alot depends on the max of the tire..
what your suspension and roads are like more pressure for bad roads to keep from bending wheels less presure on smooth roads.. too much pressure can make your tires bloat and be unstable and explode...
i wouldn't wanna see anything above 45psi ever... (ona under 50seris tire) Bill
