I would imagine you could run 32s on 15x8s with no problem. I ran 33s on 10s on my '78 with no lift. Friend with a body shop trimmed an inch or so at the bottom of the front edge where it barely rubbed. '79 had 33s on 10s but I had the front springs re-arched a little to level it. Only pics I have of them but you can see the '78 is slightly nose-down in stock form.
