Re: Why don't I like how my new GC Overland drives?
Actually, the tire placard on the vehicle is the recommended pressure, not the maximum. The maximum is imprinted on the tires themselves (51 lbs I believe for the 10" factory tires).
But, if you read the VIN placard on the door you'll see that the recommended pressure is what it takes for your vehicle to maintain it's GVWR. So, by extrapolation you can determine that the "recommended" pressure is actually the Minimum pressure.
I run 36 lbs all around unless I'm towing. For towing I increase to 38 lbs front and 40 lbs rear. By watching the tire pressure rise with the tire temps I find these pressures to be where the percentage pressure gain is the lowest indicating the least amount of heat is being generated.
