NO, not since the RX-8 rims are 18 inches in width. The 19's won't fit on them.

Bump. I've put 255s on successfully in the rear, but I haven't heard anyone going bigger....would be interesting to hear opinions from the "fitment pros" out there. TireRack doesn't offer any size options bigger than 245. <shrug>

I have 275/35/18 Hoosiers on the stock 8" rims for autocross, and there is plenty of room. They are on all four wheels, and there is no rubbing, hitting, or interference of any kind (even at full lock in the front).

I think those rims and tires will fit fine on the car.

Hey tim, do you have some good up close photos of your 8 in autocross trim? I'd love to see how 275 looks.

I'd like to see that to..sounds like it would have a nice stance to it..

* I think he was asking about 275 on a 19" rim...I don't know about that...it all depends on the Rim + tire combo..offset, sidewall, width...275 seems kinda tight on a 19" you can't shrink less than 35 on the side wall because you're already at rim bending specs....I think a 275/35 would be asking for trouble...I think you'll scrub on the front...and you definitely would have to roll the fenders if you plan on dropping the car..

Remember tpryor was talking about Hoosiers and autocross. B-stock means stock wheel size (18x8) and Hoosiers are race slicks that have stiff sidewalls. So while he did say 275s fit on the stock wheel, that doesn't help for street tire size info.

There are some pictures of the 275's at the link in the signature. I am going to take some more closeups at the next even (first weekend in March), so we can do some comparing between the "old" style Hoosiers and the "new" style Hoosiers. I'll let you know when they are posted.

Thanks tpryor, that would be great.

What brand and size do you run on the street, when your not running Hoosiers?

Notice that tpryor is running the same size front and rear? The RX-8 handling is tuned for same size tires front/rear. If you go to staggered sizes, you WILL degrade the handling, introducing more understeer. That doesn't sound like much of an improvement! Some guys here are doing it, because they want the look more than they care about ruining the handling balance. It's definitely a trade-off to be aware of before you go that way.

Gordon

wheels are one of the most important things on the car. and they also are prone to the most damage even if u try to take care of em.

u can baby an engine but wheels u can only hope u see that pothole when driving.. or dont slip out when u hit the black ice

if u find that it is recommeneded to stick with the same size tires... i would say do so. its a risky chance for the car to look a lil better.

Kel you realize your really hurting your acceleration with that?The good side is your putting almost 7% less actual miles on your car.This is the main reason i didnt want to try to spin a 19 more less a 20.Have you noticed a difference?Your car looks sweet no doubt about it,but at what cost.

thankyou,i do not feel that the 8 has any acceleration
i mean its okay but no worth stating.im planing on getting another fd just for the power and keep the 8 for weekend crusing and showing.im not trying to squeeze any power out of the 8 or
worry about 20" being to big.matter of fact some people say are they 18-19 ?
all i have to say is i luv the way my car looks and the compliments
surpass my fd,which is crazy too me but....


p.s raced a blk 911 turbo last night in the s4 the 8 would of been murdered. i didnt beat him but doing some pulls and keeping up was nice.and he lives by me so we will get to play later
