wheel size/backspace for MT 275/60/15 drag radials?

i could have sworn there used to be a sticky that had "everything you ever wanted to know about buick wheels", but maybe i hallucinated it? i just scored 2 pairs of slightly worn 275/60/15 M/T drag radials from a buddy who works at a tire shop for zip. i have gta wheels on my car now, and was looking to buy a cheapo set of steel wheels to mount these freebies on to have a little fun. my car is stock height, anyone know what size/backspace wheels i should get? i'm assuming 15x8's but wanted to see if anyone has a proven setup. i was looking on summit and the choices are pretty endless!

someone correct me if I'm wrong, but I believe for 15x8 you want 3.5BS, and for 15x10 you want 4.5BS.

I have MT DR on 15x8 with 3.5 back spacing with no issues.

Thats what I was looking for, thanks!

have 4.5 bs on 8" centerline telstars w/275 60 15 m/t drag radials and airbags no rubbing issues.

X2! correct!
