After replacing a tubeless tyre, which action regarding the valve is recommended?

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

Answer: (B)

Replacing the valve is recommended because the valve stem is part of the airtight seal and can be damaged during tyre removal, bead seating, and remounting. A new valve ensures a reliable seal and helps prevent slow leaks or sudden deflation that could occur if the old valve is bent, cracked, or worn. Reusing the old valve may leave latent damage that isn’t fixed by cleaning or simply checking, and it doesn’t guarantee the seal will hold under load. So, fitting a new valve provides the safest and most dependable tyre installation.
