Special Features and Sizing of Tyres
Ensure when fitting tyres that the tyres are the right way round. The correct direction for the tyre is indicated on the tyre wall. On Schwalbe mountain bike tyres “Front” indicates the correct direction of rotation if the tyre is fitted on the front wheel and “Rear” indicates the correct direction of rotation when the tyre is fitted on the rear wheel.
The tyre dimensions are visible on the wall of the tyre. There are two dimensions: the more precise one is given in millimeters.
The number-combination 57-559 on mountain bike tyres means that the tyre has a width of 57mm and an inner diameter of 599mm when it is fully pumped up. Picture 2 This tyre size can also be given in inches, i.e. 26 x 2.25. The number-combination 23-622 on road bikes means that the tyre has a width of 23mm and an inner diameter of 622mm when it is fully pumped up.
The tyre manufacturer’s recommended tyre pressure is normally indicated on the tyre wall or included with manufacturer’s markings on the tyre. Picture 3 Picture 4 The lower of the two indicated tyre pressures guarantees greater comfort. The greater the tyre pressure, the lower the level of rolling resistance on a smooth road surface. This, however, also reduces the level of ride comfort.
The hole in the tread on the Continental 4000s tyre is not a sign of damage, but acts as a tread wear indicator. Picture 5 If you can hardly see the hole, then the tyre must be replaced.
Front and rear tyres fulfill different functions. The front tyre transfers braking power from the bike onto the ground and also has to guarantee particularly good grip in bank curves.
The rear tyre must provide good levels of traction since this is the tyre which transfers power from the drive train into the ground.
Because the tyres must fulfill different tasks, it is perhaps wise to fit one type of tyre on the front and another on the rear wheel.
Car valves cannot be fitted to wheels on Canyon bikes. You can, however, use an adapter which enables you to inflate your tyres at any petrol station.
