Tires, checking


Delivery inspection:

- Check treads and side walls for signs of
damage, if necessary, remove any foreign
bodies, such as nails and glass splinters.

- Check that tires are the same type and tread
pattern.

Inspection service:

- Measure tread depth.


Minimum tread depth: 1.6 mm (0.0625 in.)
If tread depth is close to legal permissible
minimum, i.e. if the 1.6 mm high wear indicator
spaced around tire circumference no longer has
any tread pattern, the customer must be in
formed.
Tires should also be checked for scuffing, wear
on one side, porous side walls, cuts, and
fractures.
Any defects found must be reported to the
customer.

CAUTION!

Tires of same type and tread pattern must be
used on cars with All Wheel Drive (otherwise
risk of damage to central differential).

- Check tread wear pattern:
Tread wear pattern on front tires is an indication
of whether toe and camber settings need to be
checked:
"Feathering" on tread indicates incorrect toe.
If tread is worn on one side, this is usually
caused by incorrect camber.
If wear of this nature is noticed, check wheel
alignment.
