I was under my 90 GTU checking everything out(bushings, etc......) and I noticed the the inside of me left rear tire was worn more then the outside. I checked out the other side and it was worn evenly. What is going on? Why is it just one side? And when I look at the rear tire it looks like the chamber is fine (from what I can tell).

Some thing is out of alignment, worn out, or bent.

How's the condition of the strut?

 

They are the stock ones with about 140,000 miles om them. Going to replace then as soon a possible. But why would it happen with just one and not all or even just the back two?

if its is blown out.

Easy to check: How many bounces when your press down on the left rear corner.

press down once or twice, it should not bounce more than 1 half.

For example: press down, release wait for it to come up, press again, release... it should only bounce up and not back down again by itself. if it starts going back down by itself after you let it bounce up, the strut is worn or blown out.

a bad strut will cause wear on the inside edge of the tire

 

or if it's bent. You can bend a strut, just hit a pothole or run over a curb

 

I don't remember hitting any curbs or a pot hole that would bend something. Any other idea's?????
