Caring for car tires properly: Ten golden rules for a safe journey. Tests have shown that a tire pressure that is 20 percent too low leads to up to 30 percent more tire wear.
The recommended tire pressure is listed in the fuel filler flap or in the entry area on the driver's side. Never stack more than four tires on top of each other. If the tires are stored at home, the place should be cool and dry as possible. Never use harsh cleaners with solvents, oils and chemicals.
