[OnlyaJeep]

Hi everyone!!! I was just curious about mpg and tire size also psi. So I run 30 psi I a 37x12.50r17. I programmed the tires with the tzr. Measured hight was 35 3/4. Mph at 9.5ish. This is an XR. What is everyone else at?

35x12.5x17
Nitto Terra Grappler
30-32 on pavement
15 on rocky trails
12 on sand/snow

Push to 35 psi if on a long road trip
