    Looking to order some tires for my 85 sierra 1500 . I have 7" rally wheels Im looking at 275 60 15 for the rear and 255 60 15 for the front . Or possibly 275 60 15 all the way around . The only suspension mod I have is 2" drop shackles in the rear .anyone running the 275 / 255 setup ? I have read that 275 is debatable on a 7" wheel but my research says opinions are about a 50/50 on that .
