Resistant Inner Tube Fitting Instructions
1. Preparing to fit Thorn Resistant inner tubes
after a puncture
mark the position of the valve on the tyre
remove the tyre on one side of the wheel using tyre levers. If
you hold the wheel like an artist holds a paint palette with your thumb through the wheel
by the valve then you can hold the first tyre lever down while applying the second one.
remove the inner tube, inflate it and emerse in water, bubbles will
reveal where the hole is
- remove the tyre completely from the wheel and put the valve over the mark on the tyre to
help find and remove the cause of the puncture (failure to do this will result in repeat
punctures)
check the inside of the tyre for dirt, grit or thorns etc.
2. Fitting Thorn Resistant inner tubes
- fit one side of the tyre back onto the wheel, preferably the outside of the wheel so
that you are fitting the inside of the wheel last and any marks caused by tyre levers are
concealed
- remove the inner tube valve cap and fit the valve into the wheel
- feed the inner tube evenly around the wheel without kinking it
- inflate the inner tube just enough for it to take up a tubular shape (it is necessary to
do this for the tyre to fit well and in particular for the valve to fit behind the tyre
wall rather than being pinched by it)
- refit the tyre starting at the valve. Take care not to damage the inner tube if using
tyre levers but you can do it with your hands if you have strong hands
- centralise the wheel inside the tyre and inflate to approximately 10 to 14 lbs pressure.
 Tyres can be inflated with most standard bicycle pumps, we recommend
using a foot pump with a gauge as the adaptor end is easier to fit onto a small wheel.
Important
If you over inflate the tyres then the ride is harder and above 20lbs you run the risk
of distorting the wheel. |
