I run my 35x12.50x17 KM2's at 28 psi for daily driving. I think the psi your running is extremely high and would only do so in deep snow. I'm going to assume your ride is a bit stiff under that psi as well. You want as much rubber in contact with the road as possible for better overall traction and wear. You can get chalk and draw a line on your tire, drive a few miles and gauge the psi from the wear on chalk line to see what's the best psi for you.. I'm gonna assume your gonna want to be around 26-32 psi....

Uhmm those are E load range?? I would try around 26 - 30 must ride awfully rough right now.. chalk test to find optimal pressure

Yep he's right. 28-32 about right on those but chalk it to make sure
