What percentage of your car's width is rubber?

According to Wikipedia, the NB Miata is 1680 mm wide. I run 225 tires, so that’s 450 mm of rubber. 450 divided by 1680 yields... 26.7% . More than a quarter of the car’s width is rubber meeting the road.

My 323 GTX runs 185 snow tires, and its listed width is 1645 mm. 370/1645 = 22.4%

Who’s got the most rubber in relation to car width? The least?

And fun fact: my fronts are also 285, but on 10" wide wheels. I’ve had to remind my service center of this to make sure they don’t try and rotate the tires when I go in for an oil change...

I’ll try my best to score as low as possible. My old €300 ‘86 Peugeot 205 base model is 1572 mm wide and is on 145 narrow rubber. 1572/(2*145)=0.05. So 5%.

Crossfire is kind of known for large wheels, so its 28.8% stock. Back when I wasn’t planning on selling, it was up to 31.1%. Dem meats.

Apparently the stock tires are 25.8% on a FoST. I don’t think this actually has any performance value. Weight per contact patch might, but tread patterns could easily equalize that.

I bet tires on supercars are an even smaller percentage than on most of our cars.

but it be more then 14% available contact. The 14% is the width, there is also the hight of the tire. If you can don fancy math equation using Pi to calculate the total contact patch it a large contact patch.

So the Twingo is almost as wide as the 3-series? How cars grow. My 205s, which are theoretically a segment above the Twingo, are only 1572 mm wide. 145 wide tires on the base one, 185 on the GTi if I recall correctly.

Truck is 78.9" wide. Works out to 2004 mm. Tires are 275s.

(2x 255) / 1961 = 26%

I would love to go wider, but it requires a lot more work that I don’t want to do yet. I also have trouble finding a wider tire with the amount of sidewall that I really want. The initial goal was a 275/50R18, but I couldn’t find a single damn set of tires that matched front and rear and had the stagger I wanted. Real life struggles.

My Boostang runs 255 widths. so with the car being 1915 wide, I’m at 26.6% rubber on teh road. I’m trying to get wider wheels and go to 275 in the back to put it at 28.7% rubber on the road.

I’m not sure if vehicle width is measured by widest part of the body, or mirror-tip-to-mirror-tip, but automobile-catalog.com lists my Mustang at 1824mm. The tires are 235s, so that should be about 25.8%.

295 in the back, so thats 590

so thats........ 38% in the back? and with 205 up front thats.... 26% ? so 32% overall then?.........

The twingo is fairly wide for its class anyway but it is funny how cars have grown over the years. The compact is dwarfed by a 1 series which is its closest modern relative.

27% on the Bel Air with 275s

18,7% on the Bel Air with original 7.5s

27,9% on the Pajero with 235s

The others are pretty standard

I like wide wheels :)

I have 245/45R17 so 19.3 in or 490 mm of width

So 490/1841.5 = 26.6%
