Ok so I have 24x10 Mazzi Hulk Chrome Wheels with Kumho MT KL71 38x14x24 Mud Tires (8 ply). My front 2 tires wore down really quickly and I haven't got a clue why this is happening so I needed some advice from yall Hummer experts. My rears are fine it's just my last 2 in the front wore down in 2 months of about 2500 miles. So I bought 2 more and boy was I upset ($$$$)!!! They didn't even offer me a discount! But what's my problem? Because it's starting to do it again on these 2!! It isnt the air pressure or just being a bad batch of tires or out of alignment. I've had it all checked out! I bought a Rough Country leveling kit when I bought the wheels and tires and had that installed BUT really after they installed it my hummer sut is sitting higher in the front with a lower rear. I didn't question it at the time because I just thought that was how it was supposed to be.

Any suggestions on what's going on and what I should do?

Mine was doing the same thing. I took it to the alignment shop and they rechecked the alignment. Saying it was good. The tires continued to wear and so I took it to the dealership. Found out that the front hub bearings were warn out do to having larger than stock tires on it. Had the hub bearings replaced. Took it in again for an alignment. Haven't had a problem since.

The dealership install new hub bearings with a lifetime warrenty. Not sure why the larger tires will wear out the bearings since they are the heavy duty hubs. Hope it works out for you....

Good Luck

 

My brother had a similar problem with his F150 and 6" Superlift. The problem was that the installer had the front end shocks set at the highest level. My Dad had them lower the setting making the front and back level. This cured his problem with the tire wear and also reduced stresses on the cv joints.

 

So did i. Never had a problem with em, and they did help keep the tires off the radius arms.
