tire cupping

[kx250]

My left front tire is starting to cup on the outside edge. The tires only have 2000 miles on them. I had them balanced twice and a wheel alignment with no luck. What could be the problem? It has about 70k. Thanks

They are the B.F.Goodrich.

Cupped or feathered? Some call it sawtoothed. Too much toe in could cause a problem on the outer edge. Also incorrect camber. I always mix the directions but I believe it's positive camber that leans the tires outward at the top. Either way. A noticeable uneven wear at 2000 miles? I'd take it back to the allignment shop to get them to fix it.

What is your air pressure?

 

[kx250]

My tire pressure is at 32 psi cold.

I know if my Cooper's aren't over 35-36psi cold, they cup and sawtooth like mad. It's odd...

My tire pressure is at 32 psi cold.

Are they the right size tire for ex? And is that the recommended pressure?

Are your shocks original? Sometimes a bad shock can cause cupping because the tire doesn't stay in contact with the road.

Can a bearing cause cupping. I do have the original shocks.

It could cause problems, but you'd likely know from the noise if it was that bad. Plus the allignment shop should have caught it.
