I have a 79' that hasn't been lowered or raised. What size tires do you recommend for 18's all around? And 17's all around. I'm wanting to fill the wheel whells. Post pics if you have these size wheels with tire size. I don't know for certain what sizes to go with and what looks best.
Probably going with the American Torq Thrust M style wheel.
If you with an 17 or 18 X 8, I recommend staying with what GM recommended and put on for the 15's which were 255/60/15. Therefore, a 255/50/17 or 255/45/18 would work.

With 4" backspace. If you are thinking staggered fit please post that as there are lots of choises. In 18s up to 10" wide in the rear with a 275/40 tire. Do a search on "18s". There is lots of reading.
