Inspection Service

-- Check tire wear pattern and the side walls for damage, remove any foreign bodies, if necessary.

-- Check tire treads for cupping, feathering, one-sided tread wear, porous side walls, cracks, cuts, and rim damage.

WARNING:

Inform the customer of any damage found.

Tires, Checking Wear Pattern

-- The wear pattern of the front wheels can be used to assess whether a check of the track and camber is necessary:

Feathered edges of the treads may indicate faulty toe adjustment.
One-sided tread wear is mostly caused by faulty camber.

NOTE:

If such wear patterns are found, determine the causes by checking the wheel alignment (repair measure).

-- Check the tread depth on all tires using test pin :T40139 and then write them down in the maintenance table.

Minimum tread depth: 1.6 mm

NOTE:

The minimum tread depth is reached when the tires have worn down level with the 1.6 mm high tread wear indicators -arrows- positioned at intervals around the tire.
