Advice

Running in New Motorcycle Tyres

In order for your new tyres to provide optimum performance Bridgestone strongly advises that they should be ridden very cautiously for at least the first 125 miles / 200 km in order to condition and settle them on the rim, this allows the tread surface to be “scuffed-in” and function properly.

The tyres should then be checked to ensure correct seating and inflation. After this initial period, lean-angles and acceleration and braking forces can be gradually increased. Please remember that the tyre works most efficiently after it reaches its operating temperature.

Directly after the tyres are mounted, sudden acceleration, maximum braking and hard cornering must be avoided. This will also allow the rider to adjust to the “feel” and handling characteristics of the new tyres. It is also recommended that immediately after fitting a new tyre, the dealer or fitter should ensure that the tread surface is not contaminated in any way (e.g. by excess fitting lubricant). It is also advised that the tread surface should be “buffed” with a dry cloth around the circumference, please also ensure that the label is removed before use.

To sum up, the running in of tyres serves several purposes:

The tyre needs to settle itself onto the wheel rim.
The various components of the tyre (carcass, tread strip, etc.) need to settle in to one another.
When tyres are new the tread has a smooth surface and this surface needs to be “scuffed-in” to obtain maximum grip.
The rider is able to get used to the new tyre and ride accordingly.
