When stored in accordance with DIN 7716, we recommend installing the rubber valves within 24 months of manufacture. It is essential to ensure correct installation with a suitable tool (valve mounting lever, art. no. PR01_071554_04) and sufficient lubrication (tyre mounting paste, art. no. PR01_08901241 or art. no. PR01_08901221)

Speed restriction:

• For tyres without inner tubes on cars, at speeds of >210 km/h (V, W, Y or ZR) metal valves (clamp-in) or valve supports should be used to restrict the valve deflection to a max. angle of 25u00b0.
• In a few cases, the rim design already ensures that the max. valve deflection is not exceeded. (This must be checked in each individual case by the user).
