Hitting a pothole in my Tesla Model 3 cost nearly $2700. That's a lot of money for something as simple as driving on an unmaintained road. Although Tesla only offers 20" wheels with the Model 3 Performance with Performance Package, I was determined to find some tires that were not as low profile as the original equipment Tesla tires (Michelin PS4S).
But changing wheels & tires changes many of the behaviors of a car, and can come with consequences. In this video we'll look at how much you can increase the tire sidewall by switching to 18" wheels from 20" wheels. We'll also discuss acceleration, braking, gearing, sizing, fitment, clearance, wheel curbing, aerodynamics, rolling resistance, ride comfort, wheel construction, rotational inertia, unsprung mass, and aesthetics, as they all apply to changing wheels. What difference does it make? Check out the video for full details!

    You say you don't see any benefit to lower profile tire/wheels, but cornering stability is the entire reason for a lower rubber profile. The more cushion you have the less stable that sidewall will be in a corner as the weight of the car causes the tire to flex inward. This causes more body roll, and less predictability under tighter, higher speed cornering. Of all the people I would have expected to give an unbiased pros and cons list, I figured you would have made that point.

    @Erik Lee He measured the overall diameter difference including the tire at about 0.5%. That means the circumference would also change by 0.5% and thus the speedo off by 0.5%. That would only be 0.3 MPH difference at 60 MPH. Not significant.

    that’s why I maintain that for normal driving ideal profile number for me (looks v function) is 45-55. anything lower is too large, anything larger looks too balooney. I drive 225/55 r17 on my audi. that’s also why I’m laughing at guys buying second hand large cars (limousines, SUVs) with 19+ in wheels and putting on some cheap tires, because they can’t afford premium. pathetic.

    There is another point to make that wasn't mentioned en in this video: a lighter smaller wheel/rim combination will have less giroscopic effect as well. Which results in lighter steering effort. Can you actually feel that difference? On conventional cars without powersteering the difference in feel can be quite noticable indeed. On cars with powersteering it might be less noticeable but i can actually feel the difference.

    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.

    É o pneu mais alto terá mais massa não que talvez seja regra, pois sabemos que as formulações variam, existe os de melhor tecnologia, os de material mais adequado e isto, às vezes, influencia no maior preço justificável ou não, porque o diferencial é super valorizado em excesso para justificar maior preço o que é injusto, menor custo de fabricação tem que ser maios barato, maior peso possivelmente também para a maioria e que também não é uma regra por causa da formulação, bom deixando o contraste ideológico do absolutismo e do relativismo que surge devido às formulações que integram os constituintes os compósitos das tramas também fazem efeito resultando na eficiência e no preço final e foi interessante teres mencionado que quanto maior superfície de contato maior aderência, maior atrito culminando em menor distância e tempo de frenagem, e as rodas e seus aros sofrem menos danos apesar dos contrastes, fica realmente menos apresentável o perfil mais alto do pneu mas segurança e menor avaria é pessoalmente preferível a meu ver ou a meu ponto de vista individual. Bom são observações superficiais sem especialidade, mas o campo das idéias se se puderem servir ao próximo porventura assim espero que o seja para beneficiar uns aos outros como a borracha da Amazônia é uma fórmula que observo nos tênis ser de excelente aderência porque não são usadas nas formulações como um constituintes da fórmulas da borracha dos pneus em geral a não ser que as formulações sintéticas de laboratórios os tenha superado as das borrachas da natureza que evidentemente podem ter inspirado os laboratórios a melhorar as composições das formulações sobre autoclaves, mais controle de vácuo e pressão, etc... Grato. Paz perfeita...

    Yeap. I'm not sold on low profile tires. The sidewall of a normal tire acts as part of the suspension and in this case protects the wheel. When you only have 1 inch of sidewall your just a chuckhole away from damaging the wheel. I'm not a fan of the driving characteristic of ultra low profile tires either.

    You also forgot that high profile tires have longer tread life. I had 245/35 R20's on my 2006 eclipse and they were rated for 40,000km while the stock 225/55 17R were rated for around 90,000km. You also tend to get better tread depth on high profile meaning better traction in poor weather conditions. Snow tires are also basically non existent on low profile just not enough flex in the rubber to get traction. As for handling widers tires on the front will decrease turning radius hence why many performance cars will have narrower tires on the front. Takes the 92 300ZX for.instance the front tires are 225 while the rear are 245. The wider rear tires provide for better traction on the drive tires while the narrower front tires give it a better turning radius.

    When your talking about diameter, you seem to be talking about rim size only. Going from 18 to 20 inch rim shouldn't change the total diameter because you would need to adjust the speedometer unless I'm mistaken.

    crumple zones are not the best, see new car hit telephone pole, the car wraps around the pole, hit a telephone pole with a 54 chevy, it snapped the pole off. if you get a rim slightly narrower than the tread you will scrub sidewalls on curb nefore the wheel would hit. Taller sidewalls absorb more road imperfections. wheel mass has multiple effects, Mass to accelerate and stop also gyroscope effect on steering, minimal I know but it is there.

    I'm very confused. You say in the video that the new tyres have sidewall height (from wheel rim to road) of 2.75" & they are on 18" rims, well that means that 18" + 2.75" + 2.75" = 23.5" overall diameter, but you say that they are 26.33" overall diameter and you also said that the "old" wheels were 20" with a sidewall on the tyre of "just under 2inches", so surely their overall diameter is 20" + 2" + 2" = 24" yet you said they were 26.48"....................... so what am I missing ?

    The unsprung weight saving has multiple factors attached to it. The breaks only job is stopping the wheels spinning, the heavier they are, the harder they have to work. The engine's job is just turning the wheels, the less weight the faster it does it job. The same goes for your entire suspension, which purpose is mainly keeping the wheels on the road, not smoothing out your ride. I wonder how much this changed your active braking recharge, did it have an effect on it?

  • Roman Racing
    Roman Racing3 måneder siden

    Jason, you may have addressed this but with a diameter difference of 26.48" to 26.33", it appears that the rotations per mile will be 759.14 vs. 763.46. Not that much until you turn that into a 300 mile run or about one charge. Then you're looking at 227,742 rotations vs. 229,038 rotations which becomes a bit more significant; about 8,929.03 feet. (check my math as I may have goofed something there). Be interesting if you get an opportunity to do a real world range test and see if you can detect any difference? Guess it is possible with the lower unsprung mass, acceleration may use slightly less power and the smaller contact patch may also help reduce power use so it may be moot the extra rotations the 18" tire has to make. Anyway, might be an interesting comparison. Thanks for the great videos you post explaining stuff like this. Cheers!

    Great video as always. I’m with you on sidewalls, the steering response isn’t worth it on the street. The weight of these huge wheels is just as bad. I’m dealing with the lack of choice on the PUP on the performance Y, and in the Midwest it’s completely impractical to only offer those summer tires. At least the sidewalls on the 21” wheel’s tires in 3.5” F and 3.7” R. Would you say the width of the Y PUP tires and sidewall size would have fared better on that pothole?

    You got lucky. Last time I hit a pothole that did damage, it was a chunk of one of those huge concrete slabs that they build the interstate in cities with and a massive chunk was missing that was the width of the entire lane. Cars were on both sides of me so I couldn't dodge it and I was still going about 60mph when I hit it. Cars were all over the side of the road with their hazards on and I quickly joined them. The front two tires and wheels were completely destroyed. The back ones survived without any problems but what I didn't discover until I got home was that the impact was so hard, it bent the swaybar end links and blew out one of my front struts. I ended up getting the info for the contractor company doing the road work, they were aware of the damages drivers experienced and gave me the point of contact to send all repair bill info to. I ended up getting a new set of Koni shocks and struts all around, new set of 4 wheels and tires and aftermarket endlinks. They paid the full cost of parts (about 4 grand) quickly and everyone was satisfied. I didn't cheap out either. I got some nice Michelin pilot super sports and aftermarket wheels and the Koni Yellows were a big upgrade over the stock ones.

    What about tire pressure? I have see when vehicles have the tire pressure sticker for two or more tire-wheel sizes, the lower wheel size, the lower the tire pressure required. Which makes sense, considering lower profile tires need more pressure to withstand the weight and forces (wich also is partially accomplish with robust construction/materials). I ask, because overinflated tires tend to reduce braking performance, and as per the the contact area, lowering the 20" tire pressure to an adequate one for the 18" 's, will flatten the contact area, wich in result would have an positive impact in breaking and possibly in handling too.

    The angular speed of rotation of a small disk will be higher than that of a large one. Well, the kinetic energy of a rolling wheel does not depend on its diameter. Therefore, in terms of acceleration, the only thing that decides is the mass of the disk along with the rubber, and the distribution of masses between the disk and the rubber. But not the wheel diameter :(

    I believe that the rolling frictional resistance is a much bigger deal than you think when looking into the macro efficiency side of things. Even 0.0001% is huge when looking at the total expected efficiency of the vehicle. Especially when taking into account the directions the entire industry is heading. Not to mention the amount of testing and math Tesla likes to do. Making the tire alot more like a train wheel than a tire has to be the aim.
