Tire size?

[Fox Body]

I'd say 275/50/15, but there'd be lots of tire bulge.

If you're gonna put big tires on the stock rims, you should probably stay around 245/60/15 or 245/50/15 (if they make that).

If you get 15x8" rims or anything bigger(preferably a little wider than 8, like 8.5 or 9"), you can get the BFG 275/50/15s (for back).
