What's causing this tire wear?

had this issue with mine running LP22.5's,,in fact i've had this issue with every truck i have ever owned,no matter what the brand,,getting an alignment guy to set the tracking of both rears to EXACTLY the same,,not just "within specs" will go a long way,,outfit I'm leased to is having this issue with all their new trucks,,they found out that just being "within specs" can still be way off,,as for rubber,,my problem diminished considerably when i switched to 11r rubber with shallow tread depth,,i'm rough on rubber being heavy always,,and no matter what brand of rubber i ran,,i had this issue with 29/32 or greater tread depth,,when someone can actually guarantee they have a solution,,they may become a millionaire,,,LOL

 

Was just checking out this thread. As soon as drive tire wear looks uneven, I rotate left to right and in such a way wheel rotation is reversed. I find with 11Rs, 95 to 100 psi is ideal pressure. To check if shocks are working, I use a infra red temperature reader, more accurate and easier than putting your hand on them. Also easier to check tire and wheel bearing temperature. I get really good wear out of Bridgestone M722s by doing just that. It goes without saying all bushings are good and axles aligned correctly.

Just looking at the pics, I would have said tire pressure first off. Another thing, when Michelins were made in France and Germany, they were really good, but when they made them in China they turned out crap. That's why I stopped using their tires. Now I won't buy any tire unless it's stamped "made in Japan" . Not sure where they are made on your side of the ocean.

 

Any update on your tire wear issue? The tires I have seen that were run with low air pressure had areas of irregular wear and not all the way around the tire.

 

I had a shake coming from the floor coming home the other day, but it was simply steer tires out of balance (Bridgestone R294). A wheel balance doesn't last forever.

 

Get some Centramatics and a cross fire tire pressure setup to even out tire pressures.
Nothing wrong with LP rubber when running heavy, 11R only offers increased rolling resistance.
