(1) This tire may only be used on the front axle on Models 928, 928S, 928 S4 and 911 Turbo
(2) Standard equipment from Model Year 1986 for 911 Turbo and 928S, 928 S4. Can be used on front and rear axle.
For reasons of safety, the checking of tire pressure should be accompanied by a visual inspection to ensure adequate tread depth and a check for objects piercing the tire, holes, cuts, cracks and bulges in the sidewall.
Measure tire pressure only when the tires are cold. Air pressure increases as the tires get hotter. This increased pressure must not be reduced.
Tire Storage Information
Rubber ages and is sensitive to certain substances. Ozone, fuels, oils, greases and solvents have a damaging effect.
^ 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
^ do not store tires by suspending from hooks or in stacks
Note: The assumption that tires are more wear resistant after aging is not valid. 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.
