I just purchased a 69 Roadrunner and want to put new tires and wheels on. I want 15X7 and 15X8 Magnum 500 wheels and was wondering what is the best tire size to go with the rims? I want the biggest I can get while still maintaining a fairly original look.

Thanks,
ppbmac

 

First of all welcome to the fourm.. I'm giving your question a bump so it will get the attention of the several RR guys here that can help you.. Sorry I can't but someone on here sure can.......

 

i recently went throught this with my car
I put on 15X7 P235 70R15 with a 4.25 backspace i think
but i am limited because of the fenders
since you are a later mopar, you should be able to fit more back there
not an exact answer for you, but you can use this as a starting point
