Big tires?

Anyone running M/T Sportsmen SR 31x18r15?
Have an opportunity for a pair with 15x15 rims with 3.5" back spacing...

Re: Big tires?

Is your car backhalved? That's the only way that wheel and tire would ever have a chance of fitting

Re: Big tires?

Takes a lot of energy to rotate tire that tall. Just sayin

Re: Big tires?

Car is not tubbed, nor will it be. I unlike all you purists love the look of tires outside the fenderwell. Power should not be an issue, my other thread addresses that quite well. just wondering if anyone has had luck with 15x15 rims.

A lot outside the fender well, like 5 or 6 inches.

More like 8" plus tire bulge. It's a fitment catastrophe

Re: Big tires?

I'd be more concerned with the 31" tall tire. Sawzall or a donk style lift in the rear only LOL.
