Re: 17/18 staggered wheels and tires size help
If you go to the Tire Rack site and look at "specs" you will get all the data you need. Make sure you check your backspace. I put 275-40-17's on the back and 255-50-16's on the front as I wanted the same size sidwall on both the front and back. I did a good amount of measuring to get the right tire. Now I have to tell you this was on my c-10 69, but the same process I went through with my Camaro. I have smaller diameter wheels than what you are doing as I don't care for the rubber band tire look on these classics. I have kept the same wheel diameter on the Camaros, 15's, but stagger the tire size. Good luck on what ever you decide.
