I have noticed how my rear tires have been wearing rough and that is to be expected with a rear locker. Well my passenger rear tire is wearing more than the drivers side rear tire. Whats happening? Today I am going to rotate the two tires but dayum. Since seeing this is happening to my passenger rear tire I figured it has to do with my style of driving. meaning I drive fast and take corners without a though sometimes hearing the chirping. Seems as if the tire is dragging. I have since altered my driving style to easy going on corners taking them wider and staying on the gas not to allow binding. Make sense? help me guys. lol ben

 

EDIT:
I had something here but now that I think about it, I'm sure you already considered it.

 

Buuuuuuuuuuuuuuuuuump

 

Just a guess, but the passenger tire will be the inside one when turning right, outside when turning left. In day-to-day city driving, you take a lot of short radius rights and very few short-radius lefts. Think about it - if you lived in England or OZ it'd be the other way around. With an open diff the inside just sorta coasts around, with the locker it's just the opposite.
