How to choose an inner tube :
Note all the information visible on the tire's sidewall (diameter and section).
For example, 14 x 1.90 means that the tire is 14 inches in diameter and 1.90 inches wide.
On the tire's sidewall you'll also find the dimensions in mm in the international unit ETRTO
For example, 47-254 means that the tire is 47 mm wide and has an inside diameter of 254 mm (i.e. 14 x 1.90).
Removing an inner tube:
Remove the used inner tube using the tire levers.
Checks before fitting an inner tube :
Check the condition of your tire, and replace it if necessary.
Make sure there are no foreign bodies in the tire.
Check the condition of your rim tape. Even a slightly cracked rim base can lead to punctures.
Check your rim for any alterations that could damage your inner tube.
Fitting the inner tube :
See our video before you start.
Pre-inflate the tube slightly to avoid any risk of pinching.
Insert the valve in the valve hole, making sure you use the correct type of valve for your rim.
Place your tube in the whole tire, pushing the tube so that it sits in the hollow of the rim.
Make sure you don't pinch the tube when you finally mount the tire.
Tire mounting :
Start by mounting the tire on the valve.
Finish the mounting on the opposite side of the valve to avoid pinching.
Never mount your tire with a tool or tire lever, as this can pinch and puncture the inner tube.
Tire inflation :
Inflate your tire carefully, to the pressure recommended by the manufacturer (visible on the tire sidewall in PSI or bars, 1 bar = 14.51 PSI).
Regularly check that the tire is correctly positioned when inflated.
Pro tip:
To avoid pinch punctures and get the best performance from your tires, we recommend that you check and re-pressurize your tires before every outing.
