Default tire sizes on 87 coupe

will a 315 40 17 tire and wheel fit on the rear of a stock 87 coupe without scraping the wheel wells?

thanks,

I have 275x40x17 on my 86 and have no problem. I am sure the 315x40x17 would fit.

I have 315/35-17 rear tires mounted on 11" wide wheels and they fit the car quite well. The important size here is the wheel offset.
Michelin used to make a 315/40-16 replacement tire for these cars and it fit on the original 9.5" wheels with no modifications.

I also use 17x11 wheels with 315/35/17's in the back on my 87, but it is a fairly tight fit.

I don't know the size of hub spacers that I use, but the wheels have 7 3/4" backspacing with a 9" inner lip and 2" outer lip (pretty sure).

Just make sure you have the proper offset and they will fit.
