Re: Why don't I like how my new GC Overland drives?

The manual says to keep the tire pressure at the pressure indicated on the vehicle placard or the tire inflation label, but those numbers on the stickers always say they are the maximum recommended pressure when cold.

The Tire Pressure monitoring system section in the manual says that it will only warn if one or more of the tires are "significantly under-inflated", but it doesn't define what the threshold is. They don't seem to say anywhere what the minimum recommended pressure is. Do they ever post a minimum recommended pressure? Does the minimum recommended pressure vary between the different tire sizes? Inquiring minds want to know.

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.

Re: Why don't I like how my new GC Overland drives?

The only difference that I feel is with the steering wheel spoke position that I was used to on my Durango (7:00 - 8:00 position). I now have to position my hand up more on the steering wheel (9:00 position) which isn't a big deal, I'll just have to get used to it.
