I posted this to the Falcon pages as well, but thought I'd try you guys. I'll be putting some steel wheels with stock bottle cap hubcaps on my '61 Falcon for a super sleeper effect. I have stock rear wheel wells. Can anyone help me with the widest wheel/tire combination I can fit back there? I'd like the widest 15" wheel I can get without rubbing. If you've got backspacing and actual tire size, that would be a big help. This will be my first wheel/tire fitment, and I know it can be tricky. Thanks for any help.
