Assembly Requirements: Notes
Warm Up Cold Tires to the Minimum Mounting Temperature.
NOTE:
This also applies to ultra high performance tires (height/width ratio less than or equal to 45% and speed rating greater than or equal to V).
WARNING:
The minimum mounting temperature for a tire may not be below 15°C (59°F) or above 30°C (86°F) in the center of the tire.
- 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 exposed to a temperature controlled environment until the inner rubber layers have warmed up to at least 15°C (59°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 (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.
