I don't know what kind of quality record the all season Pirellis have that come with the 2007 Cobalt SS that I bought, but they sure don't pass the stress test here in Buffalo, New York. I've had my car for 1 month and have already had 2 tires replaced due to road damage. Both instances side wall damage. So far the dealer has relaced them under warranty at no charge, but let me here it from others, Are these delicate shoes or what???

 

i did not have road damage but i had to have them replaced around 16000 miles. they went bald.
