- Using a tread depth gauge or similar tool, measure the tread depth of the wear pattern.

Is the tread depth greater than 2/32 inch?

Yes
If no performance concerns (noise/vibration) are present, the tire can remain in service. CHECK the tire pressure, ADJUST as necessary. ROTATE the wheel and tire assemblies. REFER to Wheel and Tire Rotation .

INSPECT for loose, worn or damaged suspension components. INSTALL new components as necessary. CHECK the alignment and ADJUST as necessary.

No
INSTALL a new tire(s). CHECK the tire pressure in the tires, ADJUST as necessary. ROTATE the wheel and tire assemblies. REFER to Wheel and Tire Rotation .
