You can use TIREFIT tyre sealant to seal punctures of up to 4 mm, particularly those in the tyre contact surface. You can use TIREFIT in outside temperatures down to -20 °C.
In the following situations, the tyre sealant is unable to provide sufficient breakdown assistance, as it is unable to seal the tyre properly:
there are cuts or punctures in the tyre larger than those previously mentioned.
the wheel rim is damaged.
you have driven at very low tyre pressures or on a flat tyre.
Tyre sealant is hazardous to health and causes irritation. Do not allow it to come into contact with your skin, eyes or clothing, and do not swallow it. Do not inhale any vapours. Keep the tyre sealant away from children.
Observe the following if you come into contact with the tyre sealant:

on the tyre inflation compressor. The tyre inflation compressor is switched on. The tyre is inflated. First, tyre sealant is pumped into the tyre. The pressure may briefly rise to approximately 500 kPa (5 bar/73 psi).
Do not switch off the tyre inflation compressor during this phase.
The tyre should then have attained a tyre pressure of at least 200 kPa (2.0 bar/29 psi).
If tyre sealant leaks out, make sure you clean the affected area as quickly as possible. It is preferable to use clean water.
If you get tyre sealant on your clothing, have it cleaned as soon as possible with perchloroethylene.
Please note that tyre sealant may leak out when unscrewing the filling hose.
After a maximum of ten minutes the tyre pressure must be at least 200 kPa (2.0 bar/29 psi).
If the specified tyre pressure is not achieved after the specified time, the tyre is too badly damaged. The tyre sealant cannot repair the tyre in this instance.
Damaged tyres and a tyre pressure that is too low can significantly impair braking and handling characteristics.
A tyre temporarily sealed with tyre sealant impairs handling characteristics and is not suitable for higher speeds.
After use, excess tyre sealant may leak out from the filling hose.
Tyre sealant contains pollutants.
The tyre pressure must now be at least 130 kPa (1.3 bar/19 psi).
If the specified tyre pressure is not achieved after a brief drive, the tyre is too badly damaged. The tyre sealant cannot repair the tyre in this instance.
Damaged tyres and a tyre pressure that is too low can significantly impair braking and handling characteristics.
