you have to understand
a normal tire lasts what 40,000 Miles? so thats almost 70,000 KM i think (i dont know the conversion off hand)
If after 10,000 miles there is no uneven wear, its normal
it would take 15-17,000 to show heavy uneven wear on a hard compound tire
ill show you, i am ordering my airride friday, and ill keep a report with huge amounts of camber and tires wear
