I would recommend putting the correct size tire for the rim. Get a 245 to 265. There are plenty of AWD cars that come from the factory with 255 all the way around. My Audi did. Then choose the offsets based on the correct tire width and rim width. I dont understand why some people first choose a rim that ridiculously sticks outside their fender and then limit themselves to a 225 tire so they won't rub. This is a crap way of selecting proper wheel and tire packages.

Couldn't agree with you more.

But...but...stretch is cool, right? No...no its not.

Exactly! I look at wheel sizes and offsets before the actual design. They say I'm too conservative with my choices, but I'm not electing to ride a 50k car on stretched wheels. Call me crazy. Biggest I'll go it 8.5 in front and 9.5 in rear, both with ATLEAST +35 offset. Just my preference.

Yup, this is my point.

Also, If 265 doesn't fit in the front, guess what? time to pick a different wheel spec. There are two ways to go about this:

1. Hey I want to run a 10" wide wheel in the front with XX offset and want to do whatever it takes to fit, hellaflush or whatever. Ok, then unsafely stretch a tire and be done.

or

2. Hey I want to run a 10" wide wheel in the front, but have to run a proper tire size. I hate hellaflush. Ok, you should run a 255 or 265 tire, and if that doesn't fit, then maybe rethink your wheel choice and go with a narrower wheel and/or higher offset that is easier to fit.


I understand hellaflush is what some people are going for--and that's their choice. I'm just giving my $0.02 about what is safe and what isn't. FYI, I've seen plenty of hellaflush stretched tires de-bead, then you F up your nice wheels too. I personally think normal camber and a meaty tire look awesome--on any car.

Well I'm running a 9.5" wide wheel with a +43mm offset. Far from aggressive. So if a 265/30 doesn't fit I'll try 245/35. I was just looking for advice from people that are running squared.

No worries man, i think you are headed in the right direction, we just shot off onto a tangent with the stretched 225 on 10" wide wheel thing.

Anyway, You might not need to go down to a 235 if a 265 won't fit. A 255 would look and work just fine on a 9.5. I've been running 255 on my 9.5 wheel on my S2000 for years. Of course, it depends on how much room exactly you need and how much (or how little) camber you want to run.

Here's what a 255 Bridgestone S04 looks like on a 9.5" wide wheel, decently square shoulders.

looks good, do you have any side shots? is that a 255/30?

Thanks!

It's a 255/40/17. And since you plan to go a 30 or 35 series sidewall, it's probably better you go as wide a tire as you can go so you can get more protection for your wheel lip. The 265 or 255 will be have more substantial shoulders.
