216 Practical Tips, Emergency Service<br />
Tire traction<br />
Warning!<br />
When driving on wet or slushy roads, a<br />
wedge of water may build up between the<br />
tires and the road. This phenomenon is<br />
known as “hydroplane” and may cause partial<br />
or complete loss of traction, vehicle<br />
control or stopping ability.<br />
f Reduce speed on wet surface to prevent this.<br />
Tire life<br />
Tire life depends on various factors, i. e., road<br />
surfaces, traffic and weather conditions, driving<br />
habits, type of tires and tire care.<br />
f Inspect your tires for wear and damage before<br />
driving off. If you notice uneven or substantial<br />
wear, wheels might need alignment or tires<br />
should be balanced or replaced.<br />
Tire wear<br />
The original equipment tires on your Porsche have<br />
built-in tire wear indicators. They are molded into<br />
the bottom of the tread grooves and will appear as<br />
approximately 1/2 in. (12 mm) bands when the<br />
tire tread depth is down to 1/16 of an in.<br />
(1.6 mm).<br />
When the indicators appear in two or more adjacent<br />
grooves, it is time to replace the tires. We<br />
recommend, however, that you do not let the tires<br />
wear down to this extent.<br />
Worn tires cannot grip the road surface properly<br />
and are even less effective on wet roads.<br />
Snow tires lose their traction capability when their<br />
tread depth falls below 5/32 in. (4 mm).<br />
In the United States, state laws may govern the<br />
minimum tread depth permissible. Follow all such<br />
laws.
