When checking tire pressure, also check condition of tires. Look for uneven tire wear, damage to tires and rims and damage to suspension parts.
Porsche recommends checking wheel alignment following the first 1800-3000 (3000-5000 km) of driving, or after any repairs to the suspension system.
CAUTION:
Porsche recommends replacing a tire if there is damage to the tread or sidewall and any possibility of structural deterioration.
Note:
Repairing tires with pressurized sealants or tubes is not acceptable.
Retreading tires is not acceptable.
Tire Wear
Excessive, rapid tire wear is usually attributed to driving habits.
Almost all U.S. tires have tread wear indicators. The tread wear indicator is a ridge across the tread base at 6 points on the circumference of the tire.
The ridge has a height of 1.6 mm. When tread wear reaches this point, the ridges become visible. The appearance of the wear indicators signals the need
for tire replacement.
Storing tires
Rubber ages and is sensitive to certain substances. Ozone, fuels, oils, greases and solvents have a damaging effect.
Storage information
^
store tires indoors where cool and dry. Temperatures between -10~C and +20~C (14~ F and 68~ F)
^
clean tires with water before storing
^
store tires in a dark room
^
store tires on rims and inflate to higher pressures
^
do not store tires near heat radiators, electrical equipment, fuels, lubricants, solvents or chemicals
^
do not store tires in direct sunlight or under constant fluorescent lighting. Avoid blue light protection paint on windows.
^
do not store tires by suspending on hooks or in stacks
Note:
The assumption that tires are more wear resistant after aging is not valid.
VR rated tires should not be used if older than 6 years.
Age can be determined by the last three digits of the DOT code on the tire sidewall.
For example:
If the last three digits are 197, the tire was manufactured in the 19th week of 1987.
