Here’s a tip: the paid timer gas station air supplies have you racing around your vehicle to beat the clock. Park appropriately, take off all valve covers, and quickly slightly overinflated each tire. Don’t waste time checking pressures while pump is giving you air. Then use a quality tire gauge with air bleeder button (I like Intercomp brand and keep one in each truck) and gently bleed each down to your exact desired pressure.

I have found that the pressure on the sticker is too low and is designed for a soft ride. I always got too much wear on the outside of the treads when using the sticker pressure. Now I use the average of the sticker pressure and the max presure on the sidewall. If the sticker says 32 and the max is 44, I use 38. I get a firmer ride with better handling, the tires wear evenly, and I get 1-2 MPG better gas milage.

I'm not saying you're wrong, your experience could be entirely true. However, auto manufacturers have been trying everything for the last 45 years to increase fuel mileage. If a simple increase in tire pressure could do that, they'd absolutely be recommending the max safe pressure from the factory. With that being said, an unbiased test of different tire pressures with the factory tires on a new vehicle would be very interesting.

G'day mate, you are absolutely correct!! The best way to decide what tyre pressure to run your tyres at is to monitor the wear on the tread of the tyre. I run about 10 PSI over the sticker pressures and in winter just a little bit more again to compensate for the cold. I get fantastic mileage and very good wear out of my tires. Even the guys in the industry give you the wrong advice and the pressures are always too low causing the tyres shoulders to wear out very quickly, especially with modern rounded shoulder tyres anyway. I loved your comment well done on knowing to run your tyres at much higher pressures.

It all depends on how you load the car. For somebody who drives alone a lot, the recommended pressure might be a bit too high. For somebody constantly driving with a full trunk and 4 or 5 passengers, or a fully loaded pickup truck most of the time, the recommended pressure might be a bit low. If your tires are wearing evenly and you’re not having control issues when the tires warm up, you’re probably just fine.

Motorcycle rider here, I have my tire digital reader in the pocket and know by heart what psi my Ninja 300 needs - Front 28psi, Rear 32psi. Correct reading should be checked IN THE MORNING, before you start driving. Tires warm up AFTER you drive and pressure increases, so again check PSI in the morning before you start driving. You all ride safe ✌️

How fast the tire inflates is directly related to what pressure your air tank regulator is set on. Filling a tire with 40 psi coming through the air hose takes a bit longer than if the regulator is set up to 90 psi. Use a good pressure gauge and check your pressure often when filling them up. Just drive up to Discount Tire, they check it for free. They may not make the pressure perfect but it's probably a lot better than 95% of the tires on the road right now.

On most tires it says *maximum pressure.* It does not say normal operating pressure. That maximum pressure is the pressure above which there is a significant risk that the tire will blow off the rim and cause you to lose control of the vehicle if you fill it above that pressure when the tire is cold and then if you run the vehicle at highway speeds long enough to heat the tire up a lot.

He refused to do it until I called his boss out and his boss told him where to look for the correct pressure setting.

It’s doesn’t matter when you inflate them because the pressure fluctuates throughout the day based on air temperature and heat from usage. Every change of 10 degrees in air temperature causes your tire pressure to fluctuate 1-2 psi. So if you inflate them before sunrise, then they’re over-inflated at noon. You want to inflate the tires during the time of day that you mostly drive, which likely isn’t before sunrise. And rather than the coolest part of the day, or the hottest part of the day, it’s best to inflate them at the average temperature of the day/week. So if the temperature is between 60-80F that day/week, then inflate them at 70F, which might be 10AM or 6PM, that way you have the least variance. Of course you can still inflate them at whatever time of day is convenient for you, just be sure the tires are cold, and adjust the air pressure based on the temperature you’re inflating them at. So if you inflate them at 60F, but the average temperature for the day/week is 70F, then under inflate them by 1-2 psi. If you’re driving through Death Valley at high noon in the middle of summer, adjust the air pressure for that temperature. Give it a try. Since you already inflate your tires before sunrise, check the air pressure at the hottest time of the day. It may not be much on a day that only fluctuates 10-20F, but on a day that fluctuates 20-40F it could make a big difference.

I have argued with tires shops so many times about this exact same topic. They always want to inflate to the tires' max, and I tell them don't go beyond what is listed inside my door. They never listen, and then I am standing there letting air out right in front of them before I leave. The tires I buy say 51psi max, but my truck says 35 psi. I typically run with slightly more than my door says, but only a few pounds. Like between 37 and 40. Usually 40 on the front where the engine weight is, and 37 on the rear with an empty bed. If I am hauling a lot of weight I add air to the rear tires, and if it's a heavy load I put the full max 51 psi. As soon as I am done hauling I let the air back out to 37.

Good video, Lou......many people just don't realize how essential correctly inflated tires are to safe driving.

5:48 I learned how to do this the hard way in 1976. I had been used to the automatic pumps in which the bell started ringing when it reached the pressure you set, but this time, I tried to fill my bike tire with a hose that had the gauge right on the valve. I pulled the valve and the gauge read zero, so I held it and it kept on reading zero. After maybe a minute, the tire blew up and I went deaf for the rest of the day. I realized just after that that the gauge was disabled when the lever was pulled, so you had to keep pumping and checking. I guess they are all that way because it's impossible to get a good reading while the air is flowing. Anyway, it's good it happened with just a bicycle tire; a car tire could have killed me.

Pieces of bead nailed him in the head, took out one eye and part of his skull, he was permanently deaf in one ear and had permanent damage in the other. In short, he got f'ed up bigtime in a matter of seconds. Sister once asked me why her car was riding so rough. She filled one tire to over 60psi! I told her to gtf away from the tire and let it cool down overnight before even attempting anything.

The sticker is always safe for any of the tire sizes listed. Generally, the car manufacturers want a nice ride. Tire manufacturers want better wear and performance. Neither want to compromise safety. We were all talking about putting on a different size tire and wheel which changes the volume and therefore the load/pressure figure for that tire. Since you usually go up in size not down, for that case the sticker may be a little high. Worst that will do is wear out the center of the tread faster. It is not a safety problem.

Yes sir, it's what I've always done. 👍 No issues. And another wise and common sense comment.

Really good info Lou for those unfamiliar with vehicle care. I also keep a very basic pen type gauge in the car mainly for consistency. Back in the 70's I had a after school /Saturday job as a bowser boy, engine check boy, tyre repair boy, floor sweeping boy. I learnt a lot about tyres and tube. So here's what is important about tyre pressure. 1 or 2 psi is not going to make cause much of an issue but 5 psi or greater is. Especially if the pressure in all 4 tyre's is different (yes it happens), unequal tyre pressures is a bigger issue than slightly high or low. As it can greatly affect handling and braking.

Good advice, Lou. You made some points that a lot of other YT'ers miss. Couple things to add to what you say; Nitrogen is fairly misunderstood outside of mining and industrial uses. The manufacturer sets "cold air pressure" so it is really a few pounds lower than where the tire will operate. So, either use dried air or go the few pounds higher with nitrogen. The nitrogen is really beneficial in large industrial/mining tires due to the fact that it wont let a tire burn on the inside, if you hit a powerline with a boom or dump box for example. Pressure listed on the car can be fairly accurate but consider this. How many passengers does that take into account? How much luggage in the trunk? If a pickup, the numbers are usually with a max load in the bed, so no load, they are over-inflated. I've seen a lot of variation over my career in the tire biznis. Most of the time these will be close enough, but if you really want to maximize your tire life setting the pressure with the chalk method, or watching how the nipples wear off when the tire is new and adjusting appropriately will be the best way to go.

Thank you for this advice about inflating your tyres with Nitrogen, I wasn't aware of that benefit! A lot of commercial companies and including the military paint the tyre pressure on the top of the wheel arch.

@@billmmckelvie5188 Sorry, I was imagining a scenario where only you inflated your tires. By the way, after watching this video, I came across a few articles concluding nitrogen in passenger vehicle tires is overrated. Apparently the NHTSA did a study, and so did Consumer Reports, that it doesn’t make a great difference in fuel consumption or tire life compared to just regularly checking air pressure. The greatest benefit for consumers is not needing to check tire air pressure regularly, although I recall hearing that blowouts can be less severe as well, but with proper tire pressure there are surely less blowouts. Between the cost to fill with nitrogen and the inconvenience of filling stations, there just wasn’t much of a benefit to make it worthwhile.

@@LuckyCharms777 I agree entirely with regular checking. In the UK we used to use a code word as an aide memoir for checking you car. P.O.W.E.R. Petrol, Oil, Water, Electrics, Rubber. I am old school were we used to have to check points, distributor cap and spark plugs, a slightly sandy residue on the plugs indicated a healthy engine Depending on your mileage your frequency of checking all your levels should be at least fortnightly (8,000 to 10,000 annual mileage) or weekly if you prefer. Fleet use has to be at the start of your shift due to our law. Thanks to integral tyre compressors everything is far more convenient than previously!

Good info. I would add one thing: it is best to use your own gauge, and the same gauge every time. It may not be perfectly accurate, but it will tell you how much air your tires are losing over a period of weeks. The gauge at a service station air pump may be even less accurate, and the accuracy of one gauge to another is likely to vary, so if you don't use the same pump with the same gauge at the same service station, every time you put air in your tires, the difference in accuracy between any 2 of gauges may fool you as to how fast your tires are losing air. Just use the same gauge. And don't drop it! A good bang may either change its accuracy or damage it so that it doesn't work at all. A cheap stick gauge is usually accurate enough. But use a gauge that shows your tires' pressure roughly in the middle of the gauge's range. That is where it is the most accurate. So for example if your tire is supposed to have 30 psi, use a gauge that goes from 10 psi to 50 or 60, and not a gauge that goes from 20 to 100.

If that is what you mean then the answer is by using a tire pressure gauge to keep the tire at a correct pressure, and by using a tread gauge to make sure the tire has adequate tread you will minimize the chances that the tire will get a blow out but you can still get a blow out if, for example you strike a road hazard, say a "pot-hole" (a hole in the road) or a sharp object that cuts into the tread or the sidewall. If the tire has the correct pressure a pot hole is less likely to cause a blowout, or a flat. If there is plenty of tread left, road hazards are less likely to cause a flat or a blowout.

I 've ran the max tire pressure stated on any of my vehicle tires for over 20 years. There is no question that improves the MPG, but it's a bit rougher ride.

I remember a good few years ago, my brother got his tyres changed and came to see me after. He said the ride was a bit rubbish since, I asked him whether he'd checked the tyre pressures and he said the fitter had inflated then to 45 or 47psi and stated that was the correct tyre pressure. He had 15in wheels with 185/55 on his Vauxhall Corsa and they're supposed to be around 30... I then explained that his tyre fitter was wrong (always fun explaining to people how 'professionals' are wrong) and that his overly inflated tyre would've had poor contact patch with the ground and been pretty dangerous in the rain. I also explained the door sticker at that point. So bad the misinformation out there, it's a good thing that at least the correct information provided by people like yourself can end up offering people some insight as it's clearly done here. 😊

I have switched to Cross Climate with a max pressure of 50 psi so I am experimenting with 40 psi.

For example, if the sticker recommendation is 35 PSI but your tire says Max 50 you could inflate to 40 without an issue to the tire. The ride may be slightly more stiff but rarely noticable and if your tires are wearing on both outer edges due to under inflation, this could also help it wear more evenly and lastly help with slightly better gas mileage although it's not very noticeable.

No, water does not damage the inside of your tyre. The most obvious way to know that is because you have never seen an old tyre damaged from the inside by water, but they all have water in there throughout their lifetime, as it is not avoidable when putting air in there in the usual fashion, e.g. at home / at the gas station. The inside and the outside of the tyre are made of the same rubber, and the outside is exposed to water all the time and does not get damaged, or else we would not make tyres of rubber. The seals in your water pipes are made of rubber, the seal in your tyre valve is made of rubber, most water tightening seals are made of rubber, it is not reactive to water. The reason you do not want water in your tyre is pressure control. If a litre of water changes in to the gaseous phase, it expands to ca 1 cubic metre, i.e. a factor of 1,000. So having even a little bit of water can have a substantial effect on tyre pressure as the tyre gets warm or even hot due to outside air temperature and/or driving style - but we want to keep our pressure in a controlled range for reliable performance. That is because while water fully changes to the gaseous phase at boiling point / 100 C, some of it always changes to a certain degree as a chemical property of water, even below 100 C, so if a tyre has 30-40-50 C, that already has an effect despite being nowhere near the boiling point. If all you ever do is local trips to the Starbucks, the water in a tyre does not matter, as it never heats up in a substantial way, and if it did, the driving conditions would be well below the tyre's limit. But if you hit the Autobahn for 5 hours on a hot summer day, it matters. That is why some manufacturers will also tell you to measure the pressure at e.g. 20 C, and also specify speed limits for a given tyre pressure. "Cold" tyres means different things to different people, especially seeing how fucking dumb the average person is ;) But of course tyres also have a wide range of acceptable pressure, so it rarely matters whether you check pressure at 18 or 23 C... My tyres even have 2 pressures to choose from, so what is the correct pressure is on a spectrum - it has to be - tyres take a lot of abuse from ignorance and their use cases throughout their lifetime. Therefore pure nitrogen only makes sense on the racetrack, as tyres don't usually get tortured that much on public roads.

thx man i will admit i have been maxing out my tires for 40 yrs

I fill my tires with an electric pump that plugs into my car. The nitrogen that came with new tire installation at Costco helps but still I had to add air when the cold weather came. Also, one valve has a tiny leak so I’m adding plain air once a week until I get it fixed. Nitrogen is good if you don’t have time to check your tire pressure regularly but really, I’d rather keep on top of it and same the money.

Another tip is when you take your vehicle in for an oil change have them check the air pressure in the tires and especially the spare.

This is great video My local Costco puts nitrogen in tires when you buy from them. Last year they installed brand new two filling stations and guess what it’s nitrogen. If you have local Costco check you can get free nitrogen.

I always set it at 32 cold pressure. During my driving, i can see the pressure increase to 36. If you dont want your tire to blow up, dont over inflate it. When it was new, the tire pressure was at 50 psi. The dealer did not deflate it to the correct pressure.

So looking at the recommended inflation's for that Mercedes has 28 psi in the front. At that pressure the tires will be trashed in no time. So I'll stick to running mine at 40 psi in town and 50 psi for highway use on a 51 psi max tire .

"Master Tech Lou" is in CYA mode due to liability exposure. I have been a Hypermiler for over 40 years, I used to compete in fuel economy events nationwide. If one drives relatively slow, does not corner like a race car driver, and prioritzes MILES PER GALLON, there is nothing wrong with inflating tires up to sidewall max......which is 44 PSI in most tires. I ALWAYS overinflate, and currently am driving 2,100 miles per week on the highway. My tires ALWAYS end up with perfectly even wear across the tread, as modern steel belted radials are very stiff and strong. Currently I drive a 2020 Toyota Prius L ECO, which I purchased new. I already have 280,00 miles on the odometer. Have averaged 81.55 MPG during this time. For sure, the stock Bridgestone Ecopia 422+ rubber does a good job, they are LRR tires, with a hard rubber compound and computer optimized tread pattern. The size is 195/65/15. So remember, for maximum fuel economy, you want tall, skinny tires, NOT low profile aftermarket ones. Drive a little slower than normal and put air in tires up to sidewall max. Use MOMENTUM techniques such as looking WAY ahead to the next stoplight and try to seldom use the brakes.....

hey glad to hear! again as I have stated numerous times the only goal of this video was to show of the sticker spec. from there, you can over or under inflate as needed for each individual case. thanks for watching and reaching out!

Nice video. Thank you for doing it. I can't go by the PSI recommendation on the door frame because that's for the stock tires. I don't have the stock tires. That said, I do know not to fill to the maximum listed on the tires themselves. This was a good video for confirming what I knew. You would be an excellent teacher, Bro.

Max pressure is used when carrying max load

The door frame guide is still for your specific car.

@@tioswift3676 True, but I have to take the different tires in to consideration. As an example, if the door frame is saying to fill to 35 psi and the stock tire on the car has a max psi rating of 45 psi, that's cool. But, if I have different after market tires on the car that have a max psi rating of 55 psi and I only fill it to 35 psi, they aren't getting as much air in them by percentage as the stock tires and it may damage the tires by being underinflated. Common sense comes in to play here.

Spot on. This should be taught in drivers Ed.

@@willem2544 rims aren’t. Atleast the last time I checked. I could be wrong. It’s happened before. Just ask my wife.

Really good advice here.

Thanks for the heads up!

Great advice thank you. My advice to the shop owner is to get an air dryer for your air compressor .

Thanks! That is an air dryer just not located properly. I drain it daily as its also inside a detail shop. Talk about moisture!

Yes that’s the way I do it … might add that some tires have a sidewall indicator near the tread that can show if you fill too much… the scuffs will either be over the indicator onto the sidewall…not enough air. If shy of the indicator it scuffs towards the tread and is overinflated. Usually about 32psl I have found is perfect just like the door jam recommended and totally different tire than original. Still use a quality gauge and check.

If you go 2-3 lbs lower than the tire states your good. Even wear.. Good ride.. Good gas milage.

Helpful informative video.

I like to add 10-20% more air pressure than the door spec. I find it is a little biased to comfort over fuel mileage and even wear. Remember tires leak about 1 psi per month so by going a little over you can not have to check as frequently and you stay in the sweet spot longer, especially if you are going from summer to winter.

I learned something new. Thanks man.

Great advice. Thank you.

Great info here Lou, I picked up a couple tips.

Great video, Thank you.

Lou, , thanksyou did good I understand everything that you said

My next door neighbor bought new tires on sale for his truck early last spring and had the tire shop mount & balance them for him. He bought E rated 10ply tires. (nice tires) The tire shop employees told him they don't look at the tire pressure rating on the tire they look at the sticker on the door. They had inflated his new tires to 40 psi. The tires are rated for 80 psi max. 60 psi being the minimum. I pointed it out to him because the tires looked under inflated and if he expected to get decent life out of them, he had better read the tires inflation recommendation on the tires themselves. 50 year mech/tec.
