Passenger REAR tire wear only????

Bingo. Your clutches in your differential are fried. Get a rebuild and you will wear out both tires.

umm..without rebuilding everything..try checking your tire pressure. thatll do it

what would make only one rear tire wear ALOT(ruined) and the other rear tire looks fine on a 97 cobra? Thanks much

First stop should be to check the rim. If it wobbles, it will wear a tire out quickly. Same could result from the rear shaft on that side being bent which would make the tire wobble as well. Next would be to check everything on that side to make sure nothing was bent going over a speed-bump or hole, as if the other three wheels are aligned properly, that one being toed in or out due to damage will wear the tire...

Most of that you could see by jacking up the rear, putting it on jack stands, and letting someone sit in the car and spin the rear wheels (don't need to go real fast, just moving will highlight any wobble.).

Mine has the same problem. For me, it's because the right tire will spin easier than the left tire. It's from the right/rear tire spinning while turning a right corner.

I probably could also benefit from a T-lock rebuild. Mine hasn't held up very well. I've got 33,000 easy miles on my car (stock tires), and my T-lock has been worn for quite some time.

the stock traction-lock is horrible, so anything goes. single-wheel burnouts are pretty common. The clutches are held together with a wussy spring that just doesn't keep them locked very well. A good replacement will solve that if the problem is wear during burnout rather than just driving around.

Could also be a bent/twisted axle tube. This causes the wheel to roll on an angle instead of straight ahead.

Best way to tell is to put a straight edge across the face of both rear wheels. Measure each side to the other side of the car. Measure ments should be the same.
