Method
8. Remove the existing puncture free tyre by cutting it from the rim using the Stanley Knife, extreme
care should be taken to ensure that the person does not cut them selves.
9. If a pneumatic tyre is being replaced, deflate the tyre by depressing the valve, then cut the tyre from
the wheel and remove the inner tube by unscrewing the securing nut that holds the valve to the
outside face of the wheel-rim. Again extreme care must be taken when cutting away the tyre.
10. Clamp the Round Bar in the bench vice.
11. Warm the tyre by sitting it in a bath of water at 50 degrees centigrade, care should be taken when
using hot water to avoid scolding. By warming the tyre it expands and makes fitting onto the rim
easier.
12. Place as much of the tyre as possible around the wheel-rim with the Round Bar located between the
tyre and the wheel rim.
13. Turn the wheel, using the Round Bar to guide the remaining tyre onto the wheelrim. Be careful
when doing this to make sure that your fingers or other items are not caught between the tyre and
the wheelrim and this is a pinch point.
14. Pull the wheel upwards so that the Round Bar is removed from the wheel assembly.
15. Check that the tyre is securely fitted to the wheelrim.
16. If the wheel has been changed from pneumatic to puncture free care must be taken to ensure the
brakes operate correctly. To check the brake works correctly engage the brake and ensure that the
wheel does not turn when force is applied.
Spares and Options should only be fitted by a trained and competent person
