great color, excellent wheel. tire fine.. stretched, looks like ***.. why?

more weight in rim is offset by less weight and less tread in the tire?

this is aimed at every one that does this..

i kinda understand putting a bigger tire on a rim, but this?

please, i am old. explain.

tires were dirt cheap so i picked them up (and you can see why). i am in the same boat as you though - big wheel, big tire. but that's the only reason i'm running a 265 tire on these wheels.

your answer is logical.. but so many do it on purpose.. i would love to know if there is a real reason other than i looks cool, or if fits under the fenders?

swoope if you are talking about stretched tires, its for a couple of reasons. Stretched tires provide stiffer sidewalls, therefore providing more feedback. They also help low power cars drift with a bigger tire.

Some do it for style, some do it for function. I do both........

low power cars drift is what i would think is a reasonable answer..

dont buy into the stiffer sidewall thing.

i could be wrong..

Do you rub? im getting the same setup on mine but in 19's but the rolling diameter is the same. did you roll fenders or anything? 19x10 +36 265/30/19 in the rears. I have tein flex coilovers and planning to get the fenders rolled. Im just waiting on the rims to arrive still.

unfortunately didnt end up using the 8 for autox so i cant give you any feedback if it rubs or not with stock suspension.

265/35 on a 10" wheel is hardly stretched, after all, 265mm = ~10.43"

255/35 on an 18x10 would be optimal.

You mention understanding fitting more rubber on a wheel, but why more wheel? You'll be maximizing your usable footprint as well as increasing sidewall stiffness with a very slight stretch (ie: 255 on a 10", 265 on a 10.5", etc). Why put more tire when it only allows for a fraction more grip area but increases weight and increases sidewall flex.

In short, maximized mechanical grip + maximized sidewall stiffness (allowing for better responsiveness) + minimum weight = optimal. That's my understanding, at least.

Autocrossing seems to be more rubber = better.

It also helps fitting in the fenders

Extreme stretches are for for fitting wheels under fenders and drifting, often the two overlap.

I've talked to individuals who go both ways on the subject, they each offer valid arguments but unfortunately, I have no solid experience.

Well. I tried to give an answer!

thanks,

i think. have to read more. have to look at what the tire manufactures recommend. 255 seems more suited to a ~ 9 inch wheel..

i agree!

besides, if you contact yokohama for example. they'll tell you a 255 tire will perform best on a 10" wheel.

you'll see two measurements for wheel fitment to tire.

one is measured rim width... for a 255 its 9" ... thats an industry standard.

then you'll see recommended rim width. 8.5-10" ... thats manufactured recommended. go on the low end of the spectrum for more comfort (ie: sidewall flex) go toward the end of the spectrum for more response and maximum performance from the tire.

8" or less and 10.5" and more for a 255 tire is out of the manufacturer recommended and will not perform like designed. .

but basicallly what it comes down to is to get the most from your tire, max the wheel out to the tire.

225 on an 8.5
235 on a 9
245 on a 9.5
255 on a 10
265 on a 10.5

etc...

did the research.

this tire is meant for a rim of 9 to 10.5" wheel..

bigger comment. tires and wheels make no sense on a car that might be used in autocross..

look up the specs on the tires..

i dont understand the post from the beginning..
