When should metal valves be replaced? The best thing to do is to change the tyres every time! Tyre valves are subjected to enormous stress during their service life and are exposed to many different environmental influences. These include varying levels of ozone, solar radiation and the use of chemicals. It does not matter whether it is a rim valve on a car, truck or bicycle or what material (rubber or metal) it is. For this reason, every time a tyre is changed in the workshop, not only the tyres and rims but also the valves should be inspected and tested. A safe driving experience can only be guaranteed with a regular check of the metal valves. Potential tyre pressure loss can be caused by defective rubber or metal valves. In addition, external damage to the car tyre or corrosion of the valve core can also be the cause. The consequences of tyre pressure loss include various safety risks, with increased tyre wear, increased rolling resistance and increased fuel consumption being among the less dangerous. However, broken rim valves can have the negative effect of increasing the braking distance and can lead to unsafe driving with the risk of losing control of the vehicle. In order to minimise the safety risk and to achieve an optimal driving experience, we advise you to have the metal valves checked and replaced regularly. We offer a wide range of tyre valves for cars, vans, trucks, motorcycles, scooters, tractors and construction machinery.
