I know it may seem like a weird question, but would it be ok to put a 225 wide tires on a 8.5 inch wide rims?

Also, I know that you could run 225 tires on STS class in SoloII. Could I use 8.5 wide rims if I have 225s on them? (if it is safe to use 225 on a 8.5)

Any help would be greatly appreciated! Thanks

Yes, you can. Thats really the skinniest tire you'd want to run on a 8.5" wheel. Go skinnier and the sidewall will start to turn at an angle and no longer be vertical(because you're stretching the tire essentially). It can then possibly come off the wheel...veddy bad.

Somebody correct me if I'm wrong, but I don't think you're allowed to use 8.5" wheels in STS.

I had 275s on 8.5" rims on my Supra. They bulged a little but worked fine. I think 225s might be a little too small for that wide a rim.

Edit: woops, missed the free part - try them out, certainly won't hurt.

I have 225s on a 7.0" rim and I think theres way
to much sticking out....I think 255 on a 7.5" rim
is ideal..8.0 at the most..

Yes, you can run 225 on an 8.5 wheel.

VRTElektrique is running 215's on his 17x9 R33 GTR rims.

Thanks for the input everyone! now I have less things to worry about. I asked around today at the autox today. seems like 7.5 wide is the most you could go on STS.

225's don't look right on 8.5's

If you are racing, I think it would decrease lateral grip of the tire, if anything, like someone else said... the tire could come off easier.

VRT's car looks sweet though. Love the color/rim combination.

I've had 225 on my stock '95 rims & now I have them on my 18x8.5 TE37s. They don't protect the rim much, I damaged a sidewalk earlier this week, my paint is fine though http://www.freshalloy.com/

i used to run 225s on 8" rims, so it should be fine on 8.5s

in which case 225 is too big.

if you had 6.5's then 225 would fit.<font size="2" face="Verdana, Arial[/img]Anyone have any further input on this? I had wanted to see if I could get some 225/50/15s on stock alloys (yeah, I know speedo will be slightly off)

Check out the following link. It's for the AVS Sport tire made by Yokahama. Almost all manufacturers have a recommended (or measuring) rim, and then a range of rim widths on which the tire fits. In the case of a 225/50/16, they recommend 6.0 - 8.0 inches width, and made the measurements on a 7.0 inch rim.

http://www.yokohamatire.com/window.cfm?tireModel=avssport

Check out the specs for the manufacturer of your tires and see if they recommend what you're about to do. Personally, I don't F*** with tires, and wouldn't go out of the manufacturer's recommended ranges.

We don't want to be seeing any Ford Explorer type incidents happening to any 240's.

Hope that helps,

Ryan.

Yeah, that helps a lot, thanks. I hadn't seen places where they showed a recommended rim size before. I didn't want to do anything dangerous, but I didn't think a 225 would be that bad of a stretch, so I just wanted to find out.

If TireRack sells the tire in question, you can look at the specs for that tire and it will tell you the wheel width range they fit on along with the width used in measurement.

The sidewalls are actually angled IN on most of their setups. Apparently this makes the sidewall VERY stiff so transient response is very quick. The angle of the sidewall also helps a low offset to tuck under the fender easier. With a name like "DriftinJim", you should already know this! http://www.freshalloy.com/

initial D didnt teach that one j/k heheheheh

i guess this is question for djelektrique, but do things like the tire coming off the wheel from it being too skinney for the rim happen?
got any crash stories?
