YaKuZa_GS, thank you very much, man!

I think you right .. also HOOSIERs not like any street 315 width tires, it has very flexible side walls when starting .. i will think ...

305/25-20 on 20x11.5, cut fenders.



Anything bigger will be a serious challenge. Some 315s might run on the narrow side, but the 305/25-20 Yokohama Advan Sport I had were w-i-d-e.

I believe this is wrong information and I am 100% sure this will touch the rear suspension.

I sell wheels and tires for a living so believe me when I say I know what I'm talking about and I eat, breath and sleep about offsets and sizing LOL. If you want a 11" wide rim with the most fender clearance I recommend a +37-40 offset. But you still may need to shave the rear fender because the tire is so wide but I'm not 100% certain, you might get lucky but that is your best shot. I suggest try that first and if the tire still rubs shave the rear, its not a big job or a big deal, just make sure to reseal it to prevent any rusting.
Sorry I believe you're right. It's been so long since I've messed with the wheels/suspension on that car. I was kind of guessing what my wheel offsets were. I'd say the +37-40 that you mentioned would be the correct size. I believe mine are +38 wheels in the rear.

Default 305/35/20

Will be fitting 255/35/20 mt street comp on a 20x9.5 +22 offset for the front and a set of 305/35/20 Mickey Thompson et street radial 2 in the rear on a 20x10.5 +22. Car has a 10mm spacer in the rear currently. Going try to get the rear to fit without too much camber. Fenders have already been pulled some. Going to make it work one way or another..pics coming soon. Wish me luck.

I doubt these will fit, I am on 275/35/20 with a 10" wide wheels and +38 offset and I could not fit 285/35 unless I raise the car, I am tucking about 1/2" of tire and I have less than a finger gap from tire to fender. I am on Michelin pilot sport comps I believe

I definitely will have a fitment issue. My fenders are already modded but it's definitely going to need more of a pull. I'm putting on RCA's and lifting the car up all the way on the tein coil overs. I'll find a way to make them fit...just hope it won't look too bad.

Why are you all running such tall tires? A 275/35/20 and a 305/35/20? Both of those are too tall for the vehicle. I run a 20x11 +30 with a 275/30 with shaved fenders and don't have any clearance issues.

The specific tire compound I wanted was only offered in that size for the rear...drag radials. I think my fronts will fit.. It will probably look ridiculous if I get it to fit in the rear but going to try. They are great tires..

I like a fat tire set up, and I have no clearance issues at all, I built my car to handle and a slightly larger tire offers better traction
