Tyre valve types: TR413, TPMS sensors, and metal valves
What are the different types of tyre valve?
Most passenger car tyres use either a rubber snap-in valve (TR413 — the standard black rubber valve) or a TPMS sensor valve (a metal valve with an electronic pressure sensor body mounted to the wheel). Rubber TR413 valves are rated to 65 psi (4.5 bar) and should be replaced at every tyre change (typically every 4–5 years). TPMS sensor valves contain a battery-powered pressure sensor and cost €20–€80 each to replace — the sensor battery typically lasts 5–7 years. Metal clamp-in valves (TR416, TR418) are used on aluminium wheels and commercial applications where a rubber base would not seal reliably.

Tyre valve type comparison
| Valve type | Appearance | Application | Max pressure | Replacement | Approx. cost | Notes |
|---|---|---|---|---|---|---|
| TR413 rubber snap-in | Short black rubber stem, approx. 32 mm total length. Snaps through the valve hole in the rim. | Standard passenger cars and light commercial on steel or alloy wheels | 65 psi / 4.5 bar | Every tyre change (4–5 years). Never reuse. | €0.50–€1.50 each | The overwhelmingly common type. Correct for most passenger car fitments. The rubber base seals against the wheel rim hole. Must not be over-bent — the rubber seat can crack. |
| TR414 / TR415 snap-in (extended) | Longer rubber snap-in, 45–49 mm. Otherwise identical to TR413. | Same as TR413 but for wheels with deeper offset requiring a longer reach | 65 psi / 4.5 bar | Every tyre change | €0.50–€1.50 each | Choose TR414/415 when the valve hole is recessed and the TR413 cannot be properly capped. |
| Metal clamp-in (TR416 / TR418 / TR572) | Straight metal (usually brass) stem with a rubber grommet and a hex nut that clamps to the wheel from inside. | Alloy wheels with larger valve holes, high-performance fitments, commercial vehicles, caravans | 100+ psi / 6.9+ bar | Every 5–7 years (or when rubber grommet degrades) | €2–€8 each | More robust than rubber snap-in. Requires the tyre to be demounted to replace. The rubber grommet still ages and can leak — do not assume metal = permanent. |
| TPMS sensor valve (direct TPMS) | Metal stem with a cylindrical or rectangular sensor body (1–2 cm diameter, 2–4 cm long) attached to the inside of the valve base, inside the wheel. | Mandatory on new passenger cars in EU since November 2014, USA since 2008 (FMVSS 138) | Typically 87 psi / 6.0 bar (rated to the sensor specification) | Sensor body and battery: 5–10 years (when battery depletes or seal degrades). Valve stem core: at every tyre change. | €20–€80 per sensor (OEM or aftermarket) | Contains a microprocessor, pressure sensor, temperature sensor, accelerometer, and transmitter. Communicates to the vehicle ECU via RF (315 MHz in USA; 433.92 MHz in EU). Cannot be repaired — entire sensor replaced when faulty. |
| Indirect TPMS (no valve sensor) | Standard rubber or metal valve — no sensor attached. TPMS function provided by ABS wheel speed comparison. | Vehicles with indirect TPMS systems (wheel speed-based) | Standard for valve type used | Standard (no sensor battery to consider) | Standard valve cost only — no sensor replacement | Indirect TPMS does not detect pressure directly. It monitors rolling circumference changes (deflated tyres have smaller diameter). Cannot identify which tyre is affected or the exact pressure. |
| High-pressure valve (TR600HP / TR601) | Metal valve body, often with a reinforced base. May have dual sealing. | Commercial vehicles, buses, agricultural machinery operating above 100 psi | 150 psi / 10.3 bar and above | Per manufacturer schedule | €5–€20+ | Not used on passenger cars. The valve hole size is often larger than passenger car specification. |
Why rubber valves must be replaced at every tyre change
Rubber TR413 valves degrade over time through ozone attack, heat cycling, and UV exposure. The rubber base — which seals against the rim hole — becomes harder and less elastic after 4–5 years. A degraded valve base can lose its seal gradually, causing a slow leak. More critically, the base can split or crack under the stress of inflation pressure.
A new TR413 valve costs approximately €0.50–€1.50. A tyre demount and remount because of a leaking valve costs €10–€25. Always request that new valves are fitted when tyres are changed. Reputable fitting garages fit new rubber valves as standard — if a garage asks whether you want new valves, the correct answer is always yes.
Valve core maintenance and leak diagnosis
| Issue | Cause | Test | Action |
|---|---|---|---|
| Slow leak through valve (not through tyre) | Worn or dirty valve core. Core not fully tightened. Valve core seat worn. | Apply soapy water to the valve end (with cap removed). Bubbles from the valve = core leak. | Remove valve cap, use valve core tool to tighten (1/8 turn). If still leaking, replace core (€0.50 each). |
| Valve core replacement | Core not sealing after tightening. Core physically damaged. Replacing as part of service. | Soapy water test confirms leak. | Deflate tyre fully. Use valve core tool to unscrew core (anticlockwise). Fit new core with thin thread sealant. Re-inflate and test. |
| Missing or broken valve cap | Cap lost or cracked. Cap threads worn. | Visual. | Replace immediately. The cap is not the primary seal — the core is — but a missing cap allows dirt and water into the core seat, causing long-term leaks. Metal-to-metal caps with internal sealing O-ring are superior to standard plastic caps. |
| Bent valve stem (rubber TR413) | Kerb contact, tyre fitting damage, impact from road debris. | Visual — stem is no longer approximately perpendicular to the rim. | Do not straighten. A bent rubber valve may have a cracked base or torn rubber — straightening risks tearing the seal. Replace the valve (requires demounting the tyre). |
| Corrosion on metal valve (nut or stem) | Winter road salt, galvanic action between metal stem and alloy wheel. | Visual — white or green corrosion deposits around the valve base or nut. | Replace the valve at the next tyre change. In severe cases, the nut may seize to the valve — penetrating oil and careful use of valve core tool required. Anti-seize compound on threads at installation prevents this. |
TPMS sensor service guide
Direct TPMS sensors require careful handling during tyre changes. The sensor body is mounted on the inside of the valve stem — demounting and remounting a tyre causes mechanical stress on the sensor mounting. Most TPMS sensor failures occur during or shortly after tyre changes.
| Situation | Action | Cost |
|---|---|---|
| Seasonal tyre swap (same wheels, two sets) | Each set of wheels (summer/winter) has its own sensors. The TPMS system must "learn" which sensors are active after each swap — some cars do this automatically; others require a magnet or driving reset procedure. Check your owner manual. | No component cost — just the reset procedure |
| New tyres fitted to existing wheels with TPMS sensors | Replace valve stem O-ring (the rubber seal between the sensor body and the valve stem), and the valve core. These seal components degrade at high temperature and should be renewed when the tyre is demounted. | €2–€5 service kit per sensor |
| TPMS warning light illuminated after tyre change | Inflate all tyres to OEM spec. Drive at >25 km/h for 10–20 minutes. Some systems require a manual reset. If the light remains, one sensor may be faulty, dead battery, or the system needs reprogramming. | Nil if just inflation/reset. Sensor replacement €20–80 if faulty. |
| TPMS sensor battery dead | TPMS sensor batteries are not replaceable (they are sealed in resin). Replace the entire sensor. Battery life is 5–10 years from manufacture — not from vehicle purchase. Sensors may die during tyre changes as demounting stresses the seal. | €20–€80 per sensor (aftermarket); €40–€150 OEM |
| Fitting winter tyres to separate steel wheels (no sensors) | Three options: (1) fit new sensors to the winter steel wheels; (2) use transferable band-type snap-in sensors (clamp to the wheel interior without valve mounting); (3) fit no sensors and accept the TPMS warning light in winter. Option (3) is legal but means no pressure monitoring — manual pressure check becomes essential. | Option 1: €80–€200 for 4 sensors + fitting. Option 2: €40–€120. |
Valve cap selection
The valve cap is not the primary pressure seal — the valve core provides the seal. However, a missing cap allows water, dirt, and road debris into the valve core seat, corroding the metal and eventually causing the core to leak.
- Standard plastic caps: adequate for most applications. Replace when cracked or stripped. The valve cap must only be hand-tight — no tools needed.
- Metal cap with internal O-ring: better protection, particularly in winter or off-road use where water ingress is more likely. The O-ring provides an additional seal at the valve cap-to-stem interface.
- Locking valve caps: require a special key to remove. Used to prevent casual deflation (e.g. bicycle racks in public areas). Not appropriate for road vehicles — emergency services or tyre fitters may not have the key.
- TPMS-specific caps: some TPMS valve stems require specific caps. Check the TPMS sensor manufacturer's guidance — an incompatible cap may impede the sensor.
Valve hole size: passenger car vs commercial
Passenger car steel and alloy wheels use a standard valve hole of 11.3 mm (for TR413 snap-in) or approximately 9–12 mm depending on the metal clamp-in specification. Commercial vehicle wheels use larger holes (15.7 mm or 16 mm for TR600HP-type valves).
When replacing a rubber snap-in valve with a metal clamp-in valve (a common upgrade to improve durability), verify that the metal valve's grommet diameter matches the existing rim hole exactly. An oversized valve body in an undersized hole will not seal; an undersized body in an oversized hole will leak around the grommet.
