My left rear tire on my tow vehicle wears down evenly at 4 times the rate the right rear tire does when towing our TT. I have checked the tire pressure and it is where it should be. We are preparing for another West to East coast trip and I had to have the un-used spare put on the left rear. The tire people said it was normal to do that because of that being the power side of my 4X2 pickup. He said it was common when towing a TT. He said it even did it when towing his 5th wheel. I towed a small 5th wheel across the U.S. twice for a total of 18,000 miles and didn't experience unusual tire wear.
Does this sound normal to you RVers? Do any of you out there have this kind of a problem of more wear on one side than another? Is there anything that can be done to lessen the wear?
My setup is a 2005 5.3 Silverado 1500 4X2 and a 24'TT with about 5700 lbs GVWR. The hitch is an "Equal-i-zer" with built in dual anti-sway bars. When setting up the hitch I was able to get the pickup and TT perfectly level with there being only 1" difference in height between the front and back of the TT. On the freeway we average 60mph and rarely go 65.
Thanks in advance for your ideas and help. Barbron

Because of it's the "powerside" of your trucks rear end. Need to rotate the rear tires more often so you get more even wear. JMHO

Unless you like to do burnouts and have an open differential that makes no sense at all. If the tire wears evenly but much faster than the one on the right my only explanation is a tire compound difference. If it wears unevenly then there may be an alignment issue at play or a suspension problem.
Very curious indeed...

I think there are a lot more right rear tires worn out on RWD vehicles. I'd have someone check the diff.

Both tires get equal torque if the differential is operating correctly.
Could be a bad tire. Try a full 4 wheel alignment check is my only thought.

I rotate all 4 of mine with every oil change. This is interesting though - the "powerside" of the truck.....I wouldn't go there again if that is what they really believe

Something has to be amiss in your rear suspension when loaded. Is it possible you have a loose or bent axle tube on that side? A good alignment shop should be able to sniff it out for you! Good luck!

Clearly the idiots who told you that have no idea how a differential works. Equal torque is applied to both rear tires are all times, by design. As a result both tires would wear perfectly even.
Unless someone was doing a lot of burnouts, in which case the RIGHT tire would wear out faster (assuming an open differential). The right tire always breaks loose first because the rotational twist of the driveline puts more pressure on the left tire (newton's law).
Your situation is curious indeed. I wonder if there was a teenager involved who wore out the tire, then rotated it to prevent daddy from figuring it out. Whatever caused it there is surely a variable that hasn't been discovered yet.
