I've been running about 32lbs, but now that it has been getting cold, the TPMS keeps going off. I just bumped it up to 37lbs to see if that would stop the ding.

The off-road shop that put on my wheels and tires put 40 psi in my 33" tires. After reading several posts on the forum, I dropped down to 32. But dropping the psi also dropped about 1.5 miles off my mpg. Acceleration also seemed a little sluggish with lower pressure. I went back to 40 psi and have kept it there. Some people may say the ride is rougher with higher pressure, but I couldn't tell any difference.

My TPMS went off once it started getting cold out I had 33 PSI and checked it went down to 30 cause of the temp drop.

ok heres the deal if you keep your 33s at 40lbs you will wear the inside tread on your tires quicker than the outsu=ide treads , so less milage out of your tires, but you will get more mpg , becuase theres less rolling resistance, i run my 33s at about 33lbs in front and 35 in the rear on the street , off road i go to between 16lbs and 18 lbs , i get a nice belly in the tire and havent broken a bead , i hope this helps you out
