Sorry Shipo, it had been a long day already when I read your post. Of course, considering my occupation, I see people every day who are trying to blame others for everything. It seems to have become a national pastime! Please accept my sincere apologies!

Cupping is typically caused by improper toe adjustment.

maybe i'm not sure what cupping is. i thought that was the term for when the shoulders of the tires are wearing faster than the center, which is due to underinflation.

"Cupping can be caused by an unbalanced tire condition, faulty wheel bearings, loose parts, fatigued springs or weak shock absorbers. Check the condition of the shock by forcefully bouncing the front end of the car several times and releasing it on the down stroke. Failure of the vehicle to settle after two strokes suggests worn shocks or struts."

I leased a BMW 530 with sports suspension. It had performance tires. BMW tuned the suspension so that the front had a camber setting that pulled the tires away from the car. So that when you cornered hard the tire on the outside as it lifted kept more tread on the ground. With wide soft tires this helped to give more traction and the car held nicely. But I noticed that the front cupped quickly. the tires lasted about 18000 and I got another set. Even when I rotated them every 3000 miles they still cupped as fast as the first set. BMW also recommend more pressure in the rears that caused them to wear in the center. So maybe DC is trying to give you better performance and is tuning the suspension a little.

thanks for the link, but that still doesn't tell me what cupping IS. That link also talks about wear on the shoulders and how that is related to underinflation, as I stated. So, apparently, cupping is a different type of wear, but what type? what does it look like?

As you run your hand along the outside or inside edge of the tire you will feel ridges along the tread edges sort of a concave effect thats like a cup. The tires will also start to whine as the ridges get deeper.
