2 Assess wear pattern of tires on front and rear axle. IMPORTANT Greater wear at the shoulder compared to the center of the tire is normal for the front wheeland-tire assemblies. On the tires of the rear wheel-and-tire assemblies the wear at the center of the tread depth is mostly somewhat more pronounced than at the tire shoulders.
If an unusual wear pattern is present,

Rectify problem.
IMPORTANT After obtaining special order.
