They will with no problem. I have 245 30 22 on front and 295 25 22 on the rear of my 06 MC SS with 8.5 on front and 10's on back with no lifters, nor rubbing issues. The only thing I did do is rolled the back wheel wells just for insurance.

Really? I bet that thing under steers like a ****...


But to answer your question, make sure the offset is right or it will be easy to get into the strut body or rear trailing arm.

Sky: From your post can I assume you have 8.5" of backspace on the front and 10" in the rear - what kind of offset do you have on the front and rear? I am trying to fit the largest tire I can in the front with an 18" wheel, 8" of backspacing and the OEM 52mm offset ( I think they call this negative offset on FWD's) - Can you help me out - thanks

You will want less offset (numerically) on a wider wheel to fit both the wider wheel and tire. Less offset will push the wheel further outboard. You won't want anywhere near negative offset though. I have +41 or 43 with 245s with some room to spare. 8" wheel.

Well the wheels didn't fit. The bolt pattern on he wheels was too big. If they did go on they would have rubbed. 255 45 20 is too big. But on another note, I'm waiting for my wiring harness and dash kit so I can put my touchscreen in. Does anybody know if the steering wheel controls will still work?

Idk the offset exactly, I have a set of lorenso wl23's 22x8.5 in the front and 22x10 in the rear. And far as exaust, I have a custom 3" merged into 2.5 @ the y with flowmaster 2 chanber 40 series w/o cats nor res. Souns awesome. But I also have a 222/228 cam on a 112 lsa with Dt headers! ! ! Magnaflows are 2 mellow, sounds a step above stock. Which in my opinion is a waste of $ $ $

Flows cost power. It's proven! I like spintechs. I had some on my car and they were terrifing with the stock cam and such. 3" exhaust and Magnaflows without the res. are very loud. This car has lot's of drone and screams at WOT.
