Ok, so I'm about to pull the trigger on new 15 x 8 wheels and 35 x 12.5 x 15 tires. The two tires of choice are Mickey Thompson Baja Boss and Maxxis Razr MT. Both tires are advertised as 12.5" wide. However, actual width for the Baja Boss is 13.1" and the Razr is 13.5". Are these too wide for a 15 x 8 wheel? Should I be looking at 15 x 10?
