I want to run 14X6 Rally II's on the front of my 68 Firebird and 15X7 Rally II's on the back.
What is the largest tire I can use without rubbing.

Well, there are a few ways to go, but you may have a slight problem matching well with the 15's and the 14's. Not a big deal, just in trying to find the best over all match.

You could go with something like a 235/60/14 up front and have only slight rubbing on the inner wheel well or a-arms at full turn. But should be ok as it's the 14".

But if you wanted to match with a 235/60/15 you may have some slight rubbing on the rear outer wheel well lip, and may need to roll that. If that is not an option you could go with a lower profile, and should be able to get away with it. Like a 235/50/15, but it's still going to be close. (BFG carries these sizes)

I run 225/60/15's all the way around and would like to go with a 235/50/15 and should be ok, even in the front, but may stick with a 225 in front.

Not to say you can't go wider, as many can and do, these are just a couple of examples of something that should be a direct fit, with out complications.

I'd like to hear more of what people are running out there too.

Good luck and keep us posted!

After I posted this question I went to the FAQ's
on tires. Some excellent info there. Thanks for your reply. I think I'm going with 225-60X14
up front and 235-60X15 on the back.
