I am debating on zr1 deep dish wheels and running a 315-335 on the rear. I also like the way a 20" wheel looks but not certain about how much tire I can fit in under the car. Anyone here running a 295+ on the rear with 20" wheels and maybe a pic or two. Thanks

 

You only need a 10" wide wheel for 295s, the wheel offset is the most important.
A +50 to +44 offset would work good.

 

20x10.5's 295/25ZR20 Michelin Pilot Sport PS2's

Had 285/30ZR20's in the back, and moved them to the front when i got the PS2's

 

Did you have to roll your fender lip or did you just cut it. Do you think it is possible to go 315-335 in the rear with a set of 20" wheels. How much room do you still have in the well.

 

I had 335's on my 17's and had to do a good bit of work to get them to fit. I didnt touch the fender lips, but did completely remove the bumpstops. I had to make custom bumpstops farther under the car. and the 335's rubbed on my stock lower control arms. and under full load they would hit the fender lips when i didnt have bumpstops at all.

But i do still have room to go wider. 305 for sure. maybe a 315. the 25 series is what is giving me a little more room. the 35 series on the 335 was a tall sidewall. the 295s fit good tho. dont really see the need to go wider. if your going to be racing, i wouldnt suggest usng 20"s

the 295/25ZR20 pilot sport PS2's are just over $400 each. just something to think about
