How to use

Deflate the tyre completely, remove one side of the tyre bead from the rim, and extract the old inner tube. Partially inflate the new FISCHER inner tube to give it shape, position the valve through the rim hole, and tuck the tube inside the tyre. Re-seat the tyre bead carefully around the rim, ensuring the tube is not pinched, then inflate to the tyre manufacturer's recommended pressure. Check that the tyre sits evenly on the rim and that the valve is straight before finishing.

Recommendations

Inspect the rim and tyre interior for sharp objects or rough edges before fitting. Use the tyre pressure recommended on the tyre sidewall and avoid overinflation. Carry a compatible pump or adapter for Dunlop valves when using this tube as a spare.
