Default Problem with 255's on 8 inch wide wheel?

I know some people have done this setup on their STI's. I have been very interested in doing 255/40/17 Falken Azenis RT-615's on my 05 STI when my stockers go bald. I just talked to Dicount Tire and they said they will not mount that tire on an 8 inch wide wheel. They also say that there is almost 100% chance that the tire will fail from being mounted on such a skinny wheel. Now I am questioning doing this. Any feedback from long time users of 255/40's on an 8 inch wide wheel?

I can't afford new wheels. So I gotta stick with the stockers.

Like I said... PM/Ask Egan. I think he is running 255 Yoko's on Rota Torque's 17x8 for track tires.

ohh, ok. now I understand what you where saying. Thanks for the reply. If more people answer with positive feedback, and nobody answers with negative feedback, then I will have to try to find a place that will mount and balance 255's on a 8 inch wide wheel.

I was running 255/40-17 kumho victoracers on 17x8 rota wheels no problem for autocross. Just upgraded to the Kumho v710's in 275/40-17 on those same wheels for autocross. Again, no problem. Friend with a 05 sti just put the Flaken 615's in 255/40-17 on his stock 17x8 wheels with no problem. The tire actually does not even balloon out from the wheel and looks perfect. Just buy the tires and have someone else local mount them.

Wow, 275's on an 8 inch wide wheel. I didn't think that was possible. Yea, I have seen pictures of Falken RT-615's on 8 inch wide wheels and it looked just fine to me.

I talked to a guy named Thomas (from AZRedline forums) at the Discount tire on Broadway/Sarnoff. I called the same Discount Tire like 4 months ago and talked to a different guy and he said they could mount the tires no problem.

Use Aaron's shop on Kolb&Golf Links. I haven't had problems with them. I'd suggest the one I use up on Tanque Verde, but that is at the opposite end of town from you.

import111..........people who works at Discount tires are idiots, if they are not idiots, then they won't be working there

I just called Discount tire the other day to tried to buy some 265 for my STi because tirerack don't have them in stock, I asked them specifically for prices and availability for some specific brand and model 265s. They have to ask me what kind of car it is for, I said "I asked you for prices and availability, not whether 265s would fit on my car " I told them kindly "don't worry about it, I'll wait for tirerack to get them in stock"

To help you out, here is a STi with 255/40 on the stock wheels, the tire is BARELY wider then the wheel, I say you can go to 265 without any problem.

hehe, yea, that is 1 of the pics I have seen before of 255's on stock wheels. They look to fit just fine. Also as I told Thomas at Discount tire, "the stock STI tires are as wide or wider than most 235's and they fit just fine". So I don't see the big problem with running 255's on 8 inch wide wheels. Thomas started talking about off road trucks putting fat tires on stock wheels and the tires ripping apart cause they were to wide for the wheels.

Falken Azenis RT-615 in 255/40R17 on stock 2005STi wheels (17x8 +53):




They have been perfectly fine for me. No issues, no odd wear.

Actually, the only issue is that the rear tires tend to rub the trailing arms a tad on some harder bumpier corners (only way I know this is because there are some soft black scuffs on the trailing arms from the tires) even though there is physically 1/4"-3/8" clearance static.

A +48mm wheel (such as the rotas) would work great on this setup.

I am on Pinks with Racecomp camberplates running -2.0 front and -1.6 rear camber.

Just do it Ryan. I guess they think you're going to sue them if something breaks.

The stock STi tires are as wide as most 245 tires. I've seen enough EVOs with 255/40-17 on 8" wide wheels.

I've only seen one tire failure, and that was somebody running old r-compounds on the street. You've seen the picture of that.

yeah, if you look up specs for all the 255/40R17 tires, you will see that although most of them say 8.5 is the minimum width, some of them say 8" is the minimum... so yeah, 8" is fine especially with the Azenis which as I showed above is not too wide for the wheel.

nhluhr, thanks for the pics and info. As long as the rubbing does not dig into the tire at all, I am not worried about it. You have been on that setup for a while now as I remember, so if it's still working for you, it must be fine.

Chris, Yea, I have been searching the Evo forums about this topic as well, since they have 8 inch wide wheels stock also. So far I have not seen 1 failure, besides the R-comp tire that blew on the MR on the Kitt Peak drive.

If you want to embarrass Thomas with how wrong he is, here is a good one for you

The 06' BMW 330i with the sport package, its rear wheel and tire size are 18x8 on 255/35/18. Ask Thomas if he is correct that 255 would blow out when mounted on a 8" wheel, maybe you should contact BMW and have them recall all of their 330i because of this major safety hazard

Hahaha, yup, your right. The BMW sport package comes with 255/35/18 in the rear. That is an even shorter sidewall than the 255/40 also. Now I am totally convinced that 255/40/17 will work with out any problems. BMW knows cars pretty well, they wouldn't do something like that unless it was ok.

When I get my '06, I would like to install 18"x9" using 275/35/18. Slightly taller to help with those gay ratios, and wide enough to put the power down on track days.
