Is abnormal wear away phenomenon. If have, probable because the following reason causes,be: Toe-int of exorbitant or too low, front-wheel drive adjusts tyre pressure undeserved, tire is balanced not bearing of beautiful, hub is adjusted undeserved etc.
The first, the atmospheric pressure of tire is very important, it is affecting the service life of tire, when checking two handcart, turn round the car first circuit, check 4 wheels not should " short energy of life " , using naked eye is very easy observe.
