i have a 1988 iroc wit stock suspension but im looking to get new tires. i have the iroc 16in rims but im looking to put my cragar racing rim that i have on. their 15 inch. what size can i run on that rim..i want wide in rear but i can run stock size in front.... 265/50/15 work or can i go bigger than that. thanks for the help.

 

whats the width of the cragar wheel? about the largest you can run without any treadwear issues on a 15x7 is a 245/60. if its a 15x8, you can a 255 without any problems
