Default How big of a tire will a 69 GP take?

I've put 9" slicks on it before but never really looked at how much room there was. How big of a tire/wheel combo do you think I can get under the rear of my GP? I think they are very similar to the GTO but???

It's going to be probably 70% street - 30% track. It's got 14x7 rallys all the way around now. I'd like to go to aftermarket wheels and was just trying to decide how big of a wheel to get. Shooting for 11.50's so I don't have to put in a rollbar.

Cool....have to post some pics..
I'm thinking about looking for a 69 GP myself as a street cruiser...may even sell/trade the 60 for one.....maybe..
Good luck..

At times I think I would like to take it further (rollbar, fiberglass, etc.) but I bought this car in July 1985, 2 weeks before I tuned 16. I have a lot of fond memories driving this car and don't want to take it off the street.
