When replacing a tubeless tyre on a heavy vehicle, what is the advisable action regarding the tyre valve?

• A. Fit the same valve
• B. Have the valve checked
• C. Replace the valve
• D. Clean the valve

Answer: (C)

When you replace a tubeless tyre on a heavy vehicle, the valve through which air enters the tyre needs to be considered a wear‑and‑tear part. During removal and bead seating, the valve stem can suffer damage, the rubber seals can degrade, and the overall integrity of the valve may be compromised. A new valve ensures a fresh, secure seal and reduces the risk of slow leaks or sudden deflation once the tyre is back in service. It’s a quick, inexpensive precaution that helps maintain reliable tyre pressure under heavy loads. Reusing the old valve or merely cleaning or inspecting it doesn’t guarantee the same level of seal and safety, so replacing it is the prudent choice.
