The humble tyre valve is easy to overlook, but it plays a critical role in maintaining correct tyre pressure. A faulty valve can cause slow air leaks, leading to under-inflation, uneven wear, and reduced fuel economy. In severe cases, a failed valve can cause sudden pressure loss while driving.
There are two main types of tyre valve. Rubber snap-in valves are the most common, made of flexible rubber with a metal valve core. They are inexpensive and easy to replace. Metal clamp-in valves are used on high-performance and run-flat wheels, providing a more secure seal and better resistance to heat and corrosion. TPMS sensors are often integrated into metal valve stems.
Signs that you need a valve replacement include slow pressure loss that returns after inflation, visible cracking or perishing of the rubber valve stem, corrosion on the metal valve body, and hissing sounds when the valve cap is removed. If you are topping up a tyre more than once a month, a leaking valve is a likely culprit.
At Tayside Mobile Tyres, we replace tyre valves as part of every new tyre fitting. We also offer standalone valve replacement if your valve is leaking but your tyre is still in good condition. Our technicians carry a full range of rubber and metal valves to suit all vehicle types.
TPMS valves require special handling. Because the sensor is integrated with the valve, a damaged TPMS valve cannot simply be replaced with a standard rubber valve. The sensor must be transferred to a new metal valve body or replaced entirely. Our diagnostic tools ensure the TPMS system is recalibrated correctly after valve work.
Valve caps are not decorative — they are essential. A missing valve cap allows dirt, water, and grit into the valve core, accelerating wear and causing leaks. Always ensure your valves have caps fitted, and replace them if lost.
