Installation Instructions, Run-Flat Tires

Warm up cold tires to the minimum mounting temperature

Warm the tires in the :VAS6851 

• For injury-free mounting, the upper sidewall and the upper bead inside must be minimum 15° C (59° F).
• The internal temperature is called the core temperature.
• Rubber is a poor heat conductor, and for this reason, a cold tire must be within a temperature-controlled environment for a sufficient amount of time until the inner rubber layers have warmed up to at least 21 °C (70 °F).
• The tire surface temperature during the warm-up phase is not a measure the inside temperature.
• So that the cold tires warm up as quickly as possible, never stack them one on top of the other; store them separated from each other so that the warm air can "circulate" around them.
• Never us a room heater or a hot air gun to warm up tires because the surface temperature will heat up very quickly to a critical temperature.
• To prevent damage, only warm water or warm air (maximum 50° C (32° F) (122° F)) can be used to warm up a tire!
• If cold tires (below 0° C (32° F)) are brought into a warm room (above 0° C (32° F)), a layer of ice will start to form on the tires. This layer of ice means that humidity in the warm air is condensing on the tire.
• Once the layer of ice starts to melt, wipe up the water with a rag so that the warming up process will not be slowed down.

Warm-Up Time: 

Warm the tires in the :VAS6851 

• Using the example of a room temperature of at least 19° C (66° F) and a tire temperature of 0° C (32° F) or higher, the tires should be stored for at least two hours at least 19° C (66° F).
• If the room temperature is minimum 19° C (66° F) and the tire temperature is below 0° C (32° F), then the tires should be stored for at least 2.5 hours at a minimum room temperature of 19° C (66° F).

Recommendations: 

Warm the tires in the :VAS6851 

• If possible, let the tires stand in the workshop for one day before mounting them.
• Store the tires as high as possible on an insulated surface, pallet or something similar.
• Position the tires so that they can be "surrounded" by the warm air.
• Wipe off the sweat.
• Never heat the tires with a room heater or a hot air gun!
