Tire size for 92 formula
I am restoring a 92Formula.Currently they have 215/55/15.I plan on using the original rims but I want to go bigger/fatter.Can someone recommend a good agressive tire size that wont rub?

Re: Tire size for 92 formula
Nope. There is a crosslace wheel that is only 15x7, so a 245 would be a bit big. Try a 225-235.

Re: Tire size for 92 formula
guys.....tsk, tsk 
No Formulas ever had 15" rims. All Formulas are WS6--with 16X8 wheels (3 styles of wheels for Formulas throughout 87-92)
watajob--chuck those 15" rims and get the proper 16" rims your car was built with and your suspension desperately needs.

Re: Tire size for 92 formula
I was referring to A stock 15 x 7, not that IT was stock on Formulas.
True...Formulas, FROM THE FACTORY, got 16x8. I only meant to refer to an OEM 15x7, not necessarily stock FOR A FORMULA.
