Tire service Life
The servi ce life of tires depends on a lot of different
things including proper installation and balancing,
correct tir e pressure and driving style.

The original t ires o n your veh icle have 1/16 inch ( 1.6 mm) h igh "wear
ind icators"~ fig. 218 running across the tread . Depending on the
ma ke, there w ill be six to eight of them even Ly placed around the ti re.
Marks on the t ire sidewall (for examp le "TWI " or other symbols) indi­
cate the positions of the tread wea r indicators . Worn t ires must be
replaced. Differe nt figu res may apply in other countries ~ & .
Tire pressure
Incorrect tire pressure causes premature wea r and can cause sudden
tire blow-o ut. Fo r th is reason, tire pressu re must be checked at least
once a mont h
~ page 302.
Driving style
Driving fast aro und curves, heavy acceleration and hard b raking
increase tire wear .
Rotating tires for more even wear
For all four tires o n your ve hicle to have the same se rvice life, we
recommend that the fron t and rear t ires are rot ated according to the
tire manufact urer's suggested tire rotat ion intervals . Please
remember the fo llow ing :
• Tir e ro tat ion inte rvals may d iffe r from the vehicle serv ice intervals
out lined in your Maintenance and Warranty Booklet .
• The longer one tire is used in one locat ion on the vehicle, the more
it wears at certain points; therefore, we recommend that you follow
the t ire manufacture r's sugges ted tire rotation interva ls .
• Vehicles with front-whee l drive experience more tread wea r on the
front wheels compa red to a ll-wheel dr ive (quattro ®).
• Please ro ta te tires as shown~ fig. 219 .
• Extra care must be taken when rotating direction -specific t ires
~ page 325 .
Wheel balancing
The wheels on new vehicles are balanced. However, var ious si tuatio ns
dur ing everyday driving can cause them to become unbalanced,
resu lting in v ibr ations yo u can us ua lly fee l throug h the stee rin g
w heel.
Unbalanced whee ls mus t be rebalanced to avoid excessive wea r on
steeri ng, suspension and tires . A wheel must also be rebalanced
when a new tire is installed.
