Most cars use a simple rubber valve, but there are a few types, and the right one matters for sealing, pressure rating and TPMS. Knowing the difference helps you understand why a fresh valve goes in with every tyre, and why some cars cost more to service. Here are the main types you'll come across.
The Schrader core
Almost every car tyre valve, whatever its outer type, contains a small spring-loaded Schrader core, the part you press to let air in or out. It's the same core used on most bicycles and is what seals the air in. A faulty core is a common cause of a slow leak, see valve problems, and it can be replaced cheaply.
Rubber snap-in valves
The most common type on ordinary cars is the rubber "snap-in" valve, a flexible stem that pulls through the wheel and seals against it. They're cheap, reliable and replaced as standard with every new tyre, because the rubber perishes with age. If a fitter doesn't mention the valve, this is almost certainly what your car uses.
Metal clamp-in valves
Performance cars and some alloy wheels use metal clamp-in valves, which bolt to the wheel and are rated for higher speeds and pressures than a rubber valve. They're more durable and often look neater on a quality alloy. They cost more than a rubber valve but last well, and they're chosen where the higher speed rating or appearance matters.
TPMS sensor valves
Cars with direct TPMS have a valve that's part of a pressure sensor inside the wheel. This isn't just a stem, it contains electronics and a battery, so it costs more and needs careful handling and sometimes a service kit during a tyre change, see TPMS sensor replacement. It's the most complex and expensive valve type.
Which do you need?
You need whatever your wheel is designed for: rubber for most cars, metal for some alloys and performance cars, and a sensor valve if you have direct TPMS. We fit the correct valve with every tyre, at your home or work across the UK. Book a fit.
