no idea where to get then, but for tire size it's more important about wheel height check out http://www.1010tires.com/tiresizecalculator.asp put in what you have and then the tires you want to get and it will tell you how far off it is.

Hi Jeff, I have a 72 grand prix all so and I was wanting to upgrade to 15 inch, too and I was told it would not affect the speedometer. In fact it would help with the handling of the car a lot better a friend told me besides look a lot better. Best of luck on fixing up your grand prix. I just got mine a little over a month ago to and Iam very excited to have another one of these awsome cars. I got my first one when I was in my twentys and now 30 some years latter I have a chance to injoy another one of these cars. Have you posted a picture of your car. All was like to see some ones new project. Good luck , Keith
