Before ordering and fitting
Check for the 57-203 size on your existing tyre and confirm rim width and frame clearance. Check that a straight Schrader valve provides enough clearance for fitting and pump access.
Inspect the rim and rim tape before fitting. Lightly inflate each tube to give it shape, then fit it without trapping it under the tyre bead. Check that the tyre is evenly seated and inflate within the limits marked on the tyre and rim.
