MAINTENANCE BASICS TIRES TIRE COMPONENTS 1. Steel Cord Belt 2. Radial Carcass 3. Bead Core 4. Liner 5. Diagonal Carcass 6. Bead Cores CHECKING THE TIRES Particularly after work on rocky surfaces, check the tires for dam- age, wear and tear, and fissures. Tighten loose screws and nuts. For reasons of safety, replace the tires, if you detect one or sev- eral of the following faults: The bead core (3) is torn or buckled. The tire is excessively worn and more than a quarter of the carcass (5), not the liner (4), is exposed. The damage to the carcass (5) exceeds one third of the tire width. The single plies of the tire are separated. Radial fissures down to the carcass (5).
Deformation or damage to such an extent that the tire can- not be used anymore. CHECKING THE TIRE PRESSURE When checking the tire pressure, pay attention to fissures, peel- ing, and unusual wear and tear. Remove nails, pieces of metal, and other undesired material from the tire. If the tire bursts or if the parts of a rim consisting of sever- al parts come apart while the tire is being inflated, parts of the tire or rim may cause injury or damage to property! Use a tire-inflating hose with clamping device to inflate the tire. The hose must be long enough to ensure that you can stand erect next to the tire's tread. Stand next to the tire's tread when you inflate the tire.
Before you inflate a removed tire, secure it by means of ropes, chains, or a protecting cage. Improper work at tires and rims may cause severe injury or damage to property due to the high tire pressure! Repairs at wheels and tires must only be performed by trained experts. The service life and performance of a tire depend very much on the tire pressure. Only correct tire pressures will protect the tires from damage. 7-18
