The wheel size doesn't have anything to do with clearance and rubbing, it's the tire size. The only contribution the wheel has is the offset, which can have a major effect if it's not correct.

A 255 35 18 up front should fit fine. That should be about the same diameter as a stock tire, and not much wider.

A 295 35 18 is massive and may indeed create many headaches. That's gotta be close to a 27" tire, plus it's too wide to fit within the wheel well, so some of it will be under the quarter-panel lip, so you may have rubbing issues depending on your suspension.

I'm gonna disagree with Jim on this one and say it's 100% dependent on the wheel and NOT the tire size. I'm running 285's in the rear and could easily go to a 295 without worry (not that i'd want to though as my rear wheels are 9" wide and a 295 would bulge a bit more than I would like).They tuck in just like a stock wheel with no motifications to the body..this on a lowered car.

With that 10" rear width you can go as deep as about a 6" backspace before you're going to have to worry about rubbing on the inside..too little of backspacing the wheel will stick out and possibly rub on the outside. I prefer a wheel that tucks in close rather than sticking out..it's all personal preference. It's also dependent on your suspension setup as Jim said.

The wheel doesn't rub the wheel well, the tire does.
Your total overall width and diameter at the tread surface is what matters. The only impact the wheel has on this equation is the centering due to offset. Everything else is based on the tire. Stick a 275 on an 8" wheel or a 9" wheel and nothing (or at least very, very little) changes at the tread surface. Likewise, run a 275/40/17 or a 257/35/18 and nothing changes at the tread surface. The wheel doesn't matter except for offset changes. However, the difference between a 275/40/17 and a 285/50/17 is huge, and will have an impact because your total rotating dimensions are different.

I agree, but what I'm trying to say is that it's entirely possible to fit that size tire without modifying the body..it just depends on the specs of the wheel.

I run 18x9 and 18x10 on my car with a 285/35r18 in the rear, and I have no rubbing issues at all. I will be moving to a 295/35r18 in the rear hopefully this summer. I massaged the inner fender wells before I even went to the 18" wheel, but it would not have mattered cause these wheels don't let the tire get that close to the inner fender.

Tough in general, that is most of what I consider when fitting wheels/tires, real life, the tread is rarely what actually makes contact. Usually it’s some part of the sidewall contacting the inside or outside. That being said, the wheel does matter, even beyond just offset in that as the wheel gets wider the sidewall sticks out more. The general rule of thumb is that every ½” of rim width = about .2” difference in sidewall width.

What are you running for a front tire, your cardomain lists a 265/40, which is about ½” taller then those 285’s, doesn’t that look a little funny (I can’t tell from the pics)?

Re: 18" Torq Thrust II's

I have 18x10's on all four corners. With 285/35/18 on all four to. They are 4th gen rims with 2" adapters. The fit awsome with NO rubbing unless I lock there steering wheel all the way to the sides. If I had the IROC steering box with the stops in it for the 16 inch rims. I think there would be know problems. They are polished(well supose to be anyways. The finhsed needs alot of work.). I don't know if they have them in chrome. Adam :-)
