Here's a pic of my truck with 31's on 15x8 wheels to give this thread a little more life.
Now I have a question. My speedometer is about 4 to 5 miles per hour off at 60 m.p.h. I figured I was out of luck because I didn't think 31's came stock on these trucks. Can I buy the correct speedo gear to make the speedometer accurate? Seems like there must be one if these tires came stock on the truck.
