Excellent point. The tires are too wide for the rims. In a long winded answer, that is kind of how I ended up with the 37's. When I originally purchased the truck used, it had 325/60 18 Nittos (33x13.50) that the used car dealer had put on it. I put 40K miles on those tires and never had a problem, but it always made me a little nervous. I wanted to go to 35's when it was time for new tires, but research showed that the 33's and 35's in 13.50 were recommended for a 9-12" rim. Then I noticed that the 37x13.50 were recommended for an 8.5-11" rim. So, I know I am still outside the recommended range, but closer than I was with my original tires, or 35's.
PS - The tires are Falken WildPeak AT's.
