BFG lists a rim width range of 7.00" - 8.5". Looks? You'll have to decide. Have a look at the Americain Racing website. You can get an image of a specific vehicle with different size wheels/tires. Even with close attention to backspace, 245's may be a little close on the front. If at all possible, I'd suggest getting a trial wheel/tire for fit check.

Most performance muscle cars came with 15" wheels OE. I like 17's myself but that's just me.
