Tyre valve for tractors: Variant: Mounts valve height in mm: 57 Ø valve hole in mm: 15.7 packaging units: 10-piece tightening torque: 5-8.5 Nm How often should rubber valves be changed? For an optimum driving experience, we recommend that you also check and change the rubber valves every time you change a tyre. The rubber valves on car tyres can be damaged by various external influences. This can lead to a potential pressure loss in the valves, which represents a high safety risk. In addition, the heavy strain also shortens the service life of the rubber valves. Therefore it is recommended to check the car rubber valves regularly. Above all, attention should be paid to whether the rubber on the valves is brittle, whether there is corrosion on the valve core or whether the tyre valve has been damaged. If a broken or defective rubber valve is not replaced, various safety risks may occur. The consequences of tyre pressure loss include increased tyre wear, higher fuel consumption and increased rolling resistance. In the most dangerous case, defective car rubber valves lead to an extended braking distance and unsafe driving behaviour, up to the loss of control over the vehicle. For your own safety, we therefore recommend that you replace the rubber valve sets. We offer a wide range of rubber valves for cars, vans, trucks, motorcycles, scooters, tractors and construction machinery. Please have a look at our tyre valves.
