AIR CHAMBER 650x28/42 PRESTA

To avoid pinch punctures and obtain the best performance from your tyre, we advise you to check and, if necessary, re-pressurize your tire before each ride.

Note all the information visible on the tire's sidewall (diameter and section). For example, 26 x 2.20 means that it is a tire with a diameter of 26 inches and a width of 2.20 inches. On the tire's sidewall you will also find the dimensions in mm in the international unit ETRTO. For example, 50-559 means that it is a tire with a width of 50 mm and an internal diameter of 559 mm (i.e. 26 x 2,00).

Carefully inflate your tire to the manufacturer's recommended pressure (visible on the tire sidewall in PSI or bar, 1 bar = 14,51 PSI). Regularly check that the tire is properly positioned during inflation.

Start by mounting the tire at the valve. Finish mounting opposite the valve to avoid pinching. Never mount your tire with a tool or tire lever, as this can pinch and puncture the tube.

Check the condition of your tire and replace it if necessary. Make sure there are no foreign objects in the tire. Check the condition of your rim tape. A rim tape, even a slightly cracked one, can cause punctures. Check your rim for any damage that could damage your inner tube.

Watch our video before you begin. Slightly pre-inflate the tube to avoid any risk of pinching. Insert the valve into the valve hole, making sure to use the correct valve type for your rim. Place your tube completely inside the tire, pushing the tube so that it is positioned in the hollow of the rim. Be careful not to pinch the tube when finally mounting the tire.
