I just replaced my tires. Got 52k out of the first pair and was very happy with the performance.

These new tires which are supposed to be the same as the old tires. General something or other....

Its like glass. As soon as I hit 80 the truck becomes almost uncontrollable. I let air out of the fronts and reduced them to 48 PSI and I noticed a marginal improvement.

I haven't downed the rears yet, but I am willing to bet they are at 70PSI. When I leave wheels it looks like bicyle tires the patch is so skinny. I am probably not getting 1/2 a full foot print out of them as is.

So, before I just let em out, I thought a poll was in order. I ran my old tires at factory PSI for 25k and then reduced them a little and ran them at 60 PSI for the rest of their life. What are you running yours at?

75psi rear, 80psi front! Never know when I might hook to something, so I wan't max pressure. Not too mention they will last longer, and give better fuel economy Who cares about ride...it's a dually

Think it might be a balance problem?? Maybe a bad tire??

60 in the front and 50 in the rear. Load range E tires.

Otherwise, mine will eat the centers out of the tires.

75 psi. My truck came with Generals, which I wasn't too thrilled about. Does Michelin make the same size tire?

It's a one-ton truck. It rides pretty smoothly considering. I'd imagine that a shorter wheelbase would make you buck and pitch more over uneven surfaces.

65 Front

55 Rear

Only towing light loads; <1k in the bed and <5k towing

What you have to look for is the sidewalls of the duals rubbing under load. This creates friction heat and will lead to a blowout. Some compensate by keeping the duals aired up to max. Like signature600, if you carry different loads, you are probably best off with keeping them near max & just sucking up the ride.

Well I don't really care about ride quality, but I cruise at 75-80 on my commute. And I used to routinely hit speeds much faster. The truck is just not safe to hit those speeds with what is does.

I am hoping the air down will help. I am also replacing the shocks tommorrow and getting an alignment.

I run 60 in the front and 50 in the rear....and have had no problems as of yet

Air pressure should not make the truck more or less controlable unless under a load...at least in my opinion!!

I would still think a bad tire or balance problem, especially if you just got new tires!!

80 Front and 40 Rear while unloaded. The outsides of the front tires are still wearing.

80 in the rear and 70 in the front, michelin does make a tire for the 3rd gen dually si get about 55k out of them towing a lot of the time. i wouldnt have a general tire if you gave it to me. had them on a trailer and they sure do pitch a lot of gators when they are under a load

Big Bob

70 in front and 35 in rears unloaded. I got tired of wearing out the center of the tire in the rear because of too much tire pressure when not loaded. Not only that, but the ride is much better.

Cold, 30 rear/75 front. Truck is 8500 lbs. It's the only way to get the tires to wear square.

I agree with some of the other replys in that too much pressure in the rear will wear out the center of the tire. It's happening to me because I was to lazy to keep adjusting the pressure in the rear all the time. 30 -40 psi in the rear empty seems to be about right for ride quality and even tire wear. The way I'm going I'll be lucky to get 40K out of the OEM Generals.

70PSI all the way around when on pavement. 15psi front/18psi rear when on sand.

80 PSI all the way around.
