Hi, I have 15 x 7 now with 275 60 15 ta's. They are pulled in quite abit and would like a little wider wheel. What back spacing should I be looking for. I believe my 15 x 7 have a 4 1/2 back space. thanks

I'm surprised 275's will fit in a 67 fenderwell. on a 15x7, I believe 4-1/4" backspace puts it centered in the well. So if you go to 15x8's, I'd look for a 4-3/4" b.s. (just split the difference).

I'm running 15x8 with a 4 1/2" back space and 275/60's under the back of my 67' R/T, but..... My wheel well lips are rolled in.

My wheel well lip are still stock and I don't want to roll them. Thinking of trying to find a 15 x 8 with 5 inch back spacing and then if I need to use a small space to kick it back out and can. thanks
