Deeper tread tires on the rear axle provide better handling, wet grip, and evacuate water, thereby helping to avoid oversteer and loss of vehicle stability on wet surfaces.

Deeper tread tires on the front axle can improve wet straight line braking and stopping distance.

A wheel is out of balance when one area is heavier or lighter than the rest.

This can cause irregular treadwear and vibration, and increase the stress on the front-end parts, which may cause them to wear prematurely.

A vibration while driving indicates a problem that needs attention.

The tires, steering system and suspension system should be checked immediately to help determine the possible cause of the vibration.

This ensures that all of the tires wear evenly and last longer.

If no period is specified in your owner's manual, the tires should be rotated every 6,000-8,000 miles.If the vibration is not corrected, it could cause excessive tire and suspension wear - it could even be dangerous.All tires have treadwear indicator bars at 2/32" of remaining tread.You should always use the inflation recommended by the vehicle manufacturer.This information can be found in the owner's manual and often on a label located in the vehicle's doorjamb, inside the fuel hatch, or on the glove compartment door.Alignment generally refers to the adjustment of a vehicle's front and rear suspension parts.
