DEFINE RADIAL PULL...WHERE DID YOU COME UP WITH THIS TERMINOLOGY. IF THE MECHANIC ALIGNED THE AUTO WITH WORN TIRES HOW COULD HE HAVE PROPERLY ALIGNED CAR. TO PROPERLY ALIGN A CAR THE TIRES ON THE ALIGNMENT END OF THE CAR MUST BE OF THE SAME SIZE AND BRAND AND BE WORN EQUALLY. A TIRE WORN ON ONE SIDE WILL NOT STAND STRAIGHT AS A TIRE THAT IS WORN EVENLY.
