Jeep Gladiator - Do 35"s kill gas mileage and performance?

Автокөліктер мен көлік құралдары

Ever wondered how much bigger tires hurt your gas mileage and performance? I did some testing with my stock tires/wheels vs my 35" Nitto Ridge Grapplers and 17x8.5 Icon wheels. Did a 50 mile hwy gas mileage loop and some timed 0-60 runs using my Tazer mini.

    Man thank you so much for real world test and all the data. Out of every video and forum chat I have seen so far, this is by far the most informative. Kudos big time man and thanks again! I just bought a 2021 High Altitude and was researching all over the place for this exact info. You saved me alot of heartache lol. Instead of rushing out to get new rubber, I'll just wait until I can re-gear at the same time as most of my driving will be highway.

    Glad the video was helpful. Yea, the size/weight of the tires really has an impact. Though in all fairness, the fact that you can run 35"s without gearing and still get reasonable gas mileage is impressive. I think back to my XJ on just 31"s and was probably getting similar gas mileage. It would have been a dog with 35"s haha.

    I agree, it would be interesting to know how much impact the tires had on braking distance. While I can't say that in normal daily driving that I've noticed any real difference in braking, the reality is that heavier/taller tires will certainly increase braking distance. I have also towed an 8.5x16 enclosed trailer with my race car in it without any issue, though the trailer has trailer brakes, and I installed a Redarc trailer brake controlled.

    Thanks for the vid! The physics explains it all, and you can probably even test the concept. It's not just about the increase weight; it's about where the weight IS in proportion to the axle. The further away from the hub that the weight goes, the harder it is for a wheel assembly to be twisted. For an extreme example, you can use a barbell and a dumbell. If you held a 40 lb dumbbell in your hand, and tried to twist it from palm down to palm up, it seems relatively doable. However, if you had a 20 lb barbell and 20 lbs of weight on it and you tried to do the same thing, it would be much more difficult. This is what happens when you put on taller tires. Even if the whole assembly was the same weight, it would still be more difficult to twist and thus use more power.

    It's not exactly sports car handling on the highway, but it's good enough. On the 2020 models like mine, they have a TSB for an updated steering gear box, which I have since gotten. My understanding is that all 2021 model were built with the new gear box. Since your Rubicon will have 4.10's and stock 33"s, you shouldn't have any gearing issues at all! And congrats on the new ride! Thanks for watching.

    I know this is an old video, but very helpful. When I bought my Gladiator it already had a lift and 35 X 12.5 mud tires installed. It was getting 14.9mpg in city driving. When I bought the Jeep I was mentally prepared for poor mileage. But, you watch these Jeep channels and they go a little crazy with the lifts and tires. The 35s were fun, but kind of ridiculous. I scored some wheels/tires off Craigslist from a guy who just bought a Mohave and had immediately bought 35s. Since installing those I get between 16.5 & 17.1 mpg around town and ~21 on the highway. This is acceptable to me and about as small as I realistically can go considering anything smaller with the MOPAR lift would look ridiculous. They actually measure out to 32.5 by my measurements. On another thread someone said they got 10mpg with different gears and 40s. That's about $1 per mile! 🤪

There is a drag race formula I'm old now so can't remember exactly but basically ever pound you take off of an object like the wheels, pullys drive shaft it's equal to 8 pounds of weight on the car. If you add 20 pounds per wheel that's 80 x 8 pounds...so that's like throwing 640 pounds of shit in your bed and hauling it around

    I'm running 4.10 gears with 35s. I do see 8th frequently on flat roads, but any incline and it often drops to 6th. I was averaging 15.8 to 16.5 during the summer with very little highway. I'm getting around 13.6 - 14.4 now. I'm not going to regear, because I don't think it would be a huge difference coming from 4.10. Since you have the 3.73 ratio and want to stick with 35s, I'd recommend 4.56 gears. That would probably be the sweet spot for 35s.

    I agree. While the 4.10's still aren't ideal either, they are incrementally better than the 3.73's. At the moment though, especially since I'm not commuting to work because of Covid, it really hasn't bothered me that much. Even pulling my 8.5x16 enclosed trailer, it's not the end of the world. It runs in a lower gear and turns higher rpm, but again, it's not something that I'm doing very often at the moment. But I do eventually see going to either 4.56 or 4.88 gears. Or trade it in for a diesel, haha.

    Thanks for the confirmation on my findings. I've got a manual JL Wrangler that I just put 35's on. Around town it's not too bad, but on the highway it's painful. It's a six speed and I rarely get out of fourth. I can maybe do 5th if it's extremely flat for a long stretch. Sixth gear has become non-existent, both for highway and city. It's much more sluggish in both environments as well. Gas mileage went from about 22mpg to 17mpg. Highway mpg is worse than city. Kind of wish I had gone with 33's. But I'll be re-gearing as soon as I can come up with the $2,800 I was quoted for the job. To me, it's not really something I enjoy driving in it's current state.

A close friend just bought a JT with the 6spd and he's trying to decide what size tire he wants to go with. He's leaning towards more like a 34" tire since he's not in a position to regear in the near future.

Oh and by the way, I’ll take the lift, tires, weight and look over gas mileage every day of the week and twice on Sundays. I knew going in what I was after and what I was going to get.

    Yea, the gas mileage is definitely something to consider. I've done a few longer trips. Went for NC up to DC to pick up my race car, and took an overlanding trip to the NC mountains last year. But both of those trips I was towing a trailer so not the best comparison on gas mileage. I have just over 6k miles on the Jeep now. No real change in the gas mileage. Average 13-15mpg mixed driving.

    I've got a Tazer mini and have been happy with it. Aside from recalibrating for tire size, it also lets you turn off the autostop engine shutoff, and various other things (double tap mute to turn on the rear camera, can activate the rear camera when you use your turn signals, etc). Might be worth considering also.

  • @ScrufsGarage

    @ScrufsGarage

    3 жыл бұрын

    The 4.88's may help some, but I don't think it would be significantly better. There's still the realities of poor aerodynamics and heavier rolling mass of the tires. 3.73 gears in 7th gear (0.84), would be very similar to 4.56 gears in 8th gear (0.67). So you're still turning similar rpm's on the hwy. So instead of running primarily in 6th and 7th gear on the hwy, you would run in 7th and 8th gear. But the rpm's the engine is running at would be similar. What you gain is more power in the lower gears though, so that's a benefit.

    I had debated on going with 35"s vs 37"s. I'm glad I went with 35"s. The 3.73 definitely aren't ideal. They get it done, but regearing would be nice. 4.88's may be in my future. With Covid and work from home, I'm not driving it that much, so it's not a pressing issue at the moment. I really wish Jeep would offer the max tow (ie 4.10s) with the Overland model. I wanted some of the creature comforts that come in the Overland model, but it comes at the sacrifice of getting the max tow and 4.10s.

    Excellent point. I didn't do any A-B testing to compare, but taller/heavier tires are definitely harder to stop (can't change physics). But daily driving it's not something that I've noticed. Even towing my 8.5x16 enclosed trailer (with trailer brakes), I don't have any issues with stopping power. I'm sure if I had done 60-0 stopping distances tests, I would have seen an increase in stopping distance. Or repeated 60-0 tests would probably produce brake fade earlier. But in normal driving conditions it's not something I notice at all. Hope that helps!

    Braking performance isn't something I was able to measure, but realistically a taller heavier tire will have some impact on braking performance, especially under repeated hard braking. In a day to day setting, I can't say I've noticed a change. I didn't do any towing when my Jeep was stock, but since the lift and tires I towed my 8.5x16 enclosed trailer with the race car in it several times and didn't have any issues with braking. (the trailer had its own brakes).
