So yeah, 5” of sidewall. Or if you can’t follow that math, (305mm*.45)=137.2mm. Divide this by 25.2 to convert to inches, and you get 5.4” The point is, using aspect ratio alone to call a tire “low profile” is asinine.

I like the black wheel with more rubber look better as well. Those old classic Ferraris had much taller tires than you see today and they looked great.

You brought up the question "...why low profile tires?". To the best of my memory, LPTs came on high performance sports cars, decades ago. I read up on them and learned they were designed for high speed turns. The low side wall was meant to resist lateral inertia and not roll to the side thus keeping more tire tread on the pavement. (at the time I thought, Oh, cool...) Knowing this and and seeing how many cars now have them, needlessly, I've concluded they are there just for aesthetics, period. Furthermore, I've since purchased a (new) 2012 Ford Fusion Hybrid with (you guessed it) LPTs. Not the lowest profile but low enough to be a pain in the pocket book. LPTs do not hold up to daily driving and should not be on family sedans. One tire was ruined by a bad railroad crossing, one ruined by low air pressure causing the inside of the sidewall to become shredded (after 52 years of driving, I'd never heard of such a thing with standard tires...). When it's time to purchase my next car, I will be avoiding, as much as possible, Low Profile Tires! PS, ...good videos, very comprehensive.

This is the best modification for this car. After three weeks of using the 18” wheels I can say the car just rides incredibly. And also the shape variability of a higher profile tire allows the car to maintain contact over rough pavement. I cannot think of a mechanical reason I would use the 20” wheels other than for wanting the ultra thin tire look. I strongly recommend going to the 18 wheel.

Disagree, maybe drop it to 40psi, but he is not running "high" pressure. Over the many years, on similar size 18" I ended up running 42psi (40 on cold in "winter" here in NZ). I run treadwear 240 tyres, and they last about 40,000kms on terrible chip seal roads with lots of tight corners. Dropping to 36psi leads to excessive outside wear. There is no performance sacrifice in going from 36 to 42. The tyres I normally run are 245/45/R18 Bridgestone RE003 (before I ran RE002 and RE001 with similar results). Of course this is very tyre dependant, but I don't even bother looking at anything above treadwear ~300. The RE003 have very thick sidewall.

Finally some common sense about tires. Well done!

Also a comment on the added side wall causing some extra lateral squish in handling. I completely agree that the added sidewall is a net positive but it does allow the car to squirm a bit in entering and exiting an aggressive turn maneuver. Your review of the tire change is the best I have seen anywhere, you do an awesome job!!

One of the best videos yet. A taller tire will make a ride much more compliant and street friendly with a car that has a sportier seat and stiffer suspension. Like an S2000.

I got some 16" steelies for winter, and I've got to say the ride is so smooth (over stuff that you could feel through the already quite plush suspension); perfect for winter when you're not pushing it anyway.

Road cars have lots of extra suspension travel and there isn't nearly so much need for the cushioning effect of higher profile tires. Moreover, track tires are generally stiffer in the sidewall and have no tread squirm to contend with, and are inflated to much higher pressures than street tires. They are also, generally, not used in the rain or cold and there are many other compromises that have to be engineered into road tires that are not a part of most race tire engineering and construction. Long story short, aspect ratio is only one of MANY variables that are part of the total equation. But it is indisputable that all other things being equal, a tire with a lower aspect ratio will handle transient conditions (corner) and stop better than one with a higher aspect ratio.

@@EngineeringExplained Number 5: Tires certainly played a pivotal role. Tires. And don't ask how much you pay in rubber for each trip over 300mph. Seriously, buy/rent an airplane for anything that fast. Road friction keeps telling you to stop being so silly. Never mind the car simply can't turn at all significantly over 200mph (and won't make any real turn well under that). Also Bugatti/VW has to sell a lot of upgrades to homulugate the car to qualify for the record. It isn't in the books yet.

The standard chiron tires cost around $30,000 and need to be replaced every 2500 miles. That is for driving up to the 260ish mph limit. So to answer your question, a small fortune for 300mph

On my current truck I’ve stuck with small wheels this time around. Just to change things up a bit. I have a one ton Ram with 35” tires on 17” wheels. It’s been fun playing with dropping tires pressures and watch wear and ride quality. These tires max out at 65 psi. I’ve settled on running the fronts at 55 and the rear at 35 most of the time. I keep a load chart for tires handy in the truck, and I’ve weighed the axles and keep that info handy as well. Basically I’ve found if I’m loaded going to 45psi in the rears handles most things. During planting I may have over 2,000lbs in the bed with a pallet of seed. Maybe when these wear down I’ll try a 37” tire as these trucks swallow them up pretty well with the right wheel.

A ton of interesting info! Thank you. I also bought wheels from Tsportline. I got 19 inch for winter tires, same color as the car. Nice looking and much lighter than original 20 inch, quite happy with them.

245/45/R18 would have been a better choice. The diameter error would have been about .20 larger instead of your smaller choice. This size (26.68 in ) or slightly larger would have been more advantageous towards you stated goal of to "reduce likeihood of tire / wheel damage", while providing the same absolute error in size. The 245 would be 10MM wider and 8mm taller. That's usually not an issue for clearance and the wider aspect could increase grip. The slightly larger wheel would also visually fill the wheel well while giving the car a lower look while actually increasing ground clearance 4mm. Opportunity lost.

Wider might mess with the aero of the car though, 5mm x 23" sticking out the side of the wheel well. Also larger size reduces acceleration.

A perfect example as to why the numbers on a tire are more of a general guide, actual measurements and weights will vary.

We are waiting on a M3LR and we want the 18" tires to smooth the ride. Thanks for a great video on this subject!

Excellent comparison! Thanks for sharing Jason :)

Great video as always, EE! Last year while buying just a new Camry I labored over wheel size. So it's good to see you really break the decision down! My heart wanted the "sporty" XSE which came with 19" wheels while the cheaper and uglier LE trim came with everything practical including 17" wheels. Practical and boring. I finally compromised getting a 2019 SE which kind of hit a sweet spot in looks, practicality and cost. And came with 18" wheels. Anyway, I wondered if I should have gone with 17" wheels but now I'm thinking it would be hard to notice a difference between 17" and 18". Now 20" down to 18", you easily proved you made a huge upgrade to your Tesla Model 3 Performance! And those black 18" wheels look so much better than "chrome" on a sleek red car.

Interesting / great video Jason. I'm with you, I prefer more sidewall than most people, both from an aesthetic and performance standpoint.

I replaced my 195/60 99H r16 tires on steel on my Ford Galaxy with 215/55 97H r16 on aluminum and it totally transformed the car.

Nice follow up video after the pothole incident video. Well done!

I have no idea why such an obsession with low profile tyres exists! Great video!

I couldn't believe that with all Jason's background and understanding of mechanical engineering, he didn't understand the standard tyre (tire for you Yanks) codes. For a 245-45-20 tyre the codes are; 245 - the width of the tyre in millimetres, 45 - the height of the profile expressed as a percentage of the width and 20 - the diameter of the rim in inches. What's also important when changing tyres that the circumference remain constant. Any differences will affect the speedometer and acceleration. When you do the maths bwtween the 20" and the 18" tryes there is only a difference of about 12mm in circumference, therefore almost identical.

I've never liked overly low profile tyres, a bit more rubber looks tougher. There's an ideal profile I think before it actually doesn't look right anymore.

Love your channel, Jason! Always great content with a combination of objective and subjective analysis.

Really rational and articulate discussion, thank you! There's a sweet spot for wheel size/tire ratio that balances performance/responsiveness with resilience from road damage, and comfort. An 18 inch wheel with a 45% aspect ratio works for me in most applications and it's hard to justify a bigger wheel with all the drawbacks, unless you prefer and prioritize the looks or need that last bit of responsiveness. Yes, a smaller sidewall generally results in slightly quicker turn in response and perhaps a more accurate, connected feel, but for road use, I feel a 45 aspect sidewall offers the smartest balance of responsiveness with durability and ride quality - along with more efficiency. Also, the Michelin pilot tires (and others) have such great sidewall performance, it feels unnecessary to choose an even thinner sidewall unless you are tracking the car regularly. For a DD, anything more than 18 just seems like overkill; impractical and mostly for aesthetics.

At last I have some data to support my argument about low-profile tires with my buddies. Thanks Jason!

I remember years ago my BMW 318IS had 65 series and wanting 55 while all the super cars were going 45. 35 R20 on the Tesla, wow that’s very little cushion.

I'm with you here, the taller sidewalls look great, and the black wheels are lovely too. Winning all over really.

I definitely have more neurons now a the end than before watching the video:) I agree with you on the looks of the tire..great job! May you have not more punctures or potholes!

Would like to see you do an experimental analysis of the moment of inertia of the two wheels to see the actual difference

You made a very wise decision my man!

15:12 that appreciation slap though!

When shopping for a new truck we narrowed it down to two, and liking them equally, we started evaluating the things we liked and didn't care for on each. One of the things was wheel diameter, with one have 20 inch and the other 18 inch. Even though wheels size was not the only reason for us choosing the one with the 18 inch it was a factor, as on a truck which may get driven over things like a curb for loading or unloading it, to us made more sense. We also in our driving come across some high curbs when parking and hate curb rash. Since then we became aware of how much we save on tires by going with 18" In the past car shopping I find myself disappointed , because the model I really like has the sport trim, but comes with 20" wheels. After paying another grand or two for the sport trim is okay for the nicer seats, spoiler etc, but then hate the wheels and either live with them fearing potholes or have even more expense changing them out so the car can be driven on our potholed Pennsylvania roads.

The acoustic foam is likely necessary with the 20", whereas the 18" will absorb more of the noise with the taller sidewall and overall more mass.

Thanks for the video review of the 18 in vs 20 in wheels. Agreed with your 18" wheel choice, and I'm not surprised by the results. Formula 1 is switching to 18" wheels in 2021, while the 24hr Le Mans LMP1 class has been using 18" wheels since 2000.

Yeah, but the 18" wheels on Formula 1 cars make them slower, not faster. It's all about technology transfer from race to road, since not a lot of road cars use 13" wheels anymore.
