Not sure if this is how the tires are supposed to wear on our cars, but the insides on the back tires wear twice as fast as the outer edges. I really mean twice as fast to. I have 50% tread left on the outsides, but the inside edges are almost showing the wires.

Do I need to get the camber adjusted any?

If the tire is wearing mostly on the first tread block on the inside, then you need more toe in. This is typical with Supra's when they are BPU or higher. Go with some toe in. Most places will set the toe at 0. This is not enough.

Steve,

Is this beacuse the suspension actually bends effectively causing a toe-out condition when there is power applied? Makes sense to me. I thought my alignment guy was wrong when he added toe-in to the rear to check the tire wear, but I went along with it. He must have been right all along.

When accelerating, the suspension squats. This upward movement can cause toe out. Basically you add toe in so the tires will be a 0 toe when accelerating.

How exactly do you do this? Also, with the problem fixed, wouldn't launching be greatly improved due to better weight distribution on the whole tire instead of just the inside?

I had the same problem on my 97 NA. The Toyota tech checked the alignment and it was in the middle of specs, but still the inside edges wore. He was afraid to tweak the alignment for fear of screwing up the handling. Find a tech that can/will adjust the alignment to compensate for your problem, not just hit the middle of specs.
