Uneven tire wear

I'm looking for reasons why my drivers side tire wears the way it does.
1/2 to3/4 of the tire will wear will have like 4-5 32nds more than the other 1/4 to 1/2. I'm talking around not side to side. It happens about every 6-8 mo and makes the truck really shutter in the front as you can imagine. I put a new hub on that side not trying to fix this but my wheel seal kept leaking due to pitting. New bearings came with it. I just put new shocks on I don't know if that will help old ones did not seem bad but can't hurt. The alignment seems good. Could it be the tire its self being junk they are not a name brand but I forget what they are some Chinese brand. It's a 99 classic if that makes a difference.

 

Thanks mine don't look like any of them. You can't really see it un less you put a tread guage on it. In 22 years driving I never saw anything like it.

 

I'm thinking turns out my tire guy has continental steers and American made Kelly's for $309 installed. The chineeses ones were $280 not that big of a differance. Kinda shot my self in the foot with them.

 

The tire shop up here buys in tractor trailer loads he has a dairy barn he stores them in. The nice thing is he passes the savings on to us. Yes I messed up twice with two sets never bothered to ask about other prices. I heard a number I liked and took it.

 

Prob. Around 100k I could have got twice that out of American maybe more.
