Well my "Check Tire Pressure" light came on this morning. My rear driver's was low. Upon checking the rest of them, I found they were all at 25psi. I put them to 40 (44 on the sidewall)but I don't like the harsher ride over small bumps. What pressure are you guys running? I've always run about 3-5 less than what the sidewall says. (30-32 on a 35 tire, ~40 on a 44 tire).
