III - Pressure General
Adhere to the pressure recommended by the vehicle manufacturer, regularly checking that this is proving suitable for your particular use of the bike
Tyre PRESSURE If a tyre is inflated when hot, the pressure must be adjusted in line with manufacturer recommendations. To be correct, you should be aware that the pressure may be around 0.3 bars higher than the recommended level when cold.
example: Hot tyre pressure reading = 2.6 bar Recommended cold pressure= 2,5 bar What we should read = 2.8 bar Add 0.2 bar
Inflation with nitrogen Does not mean that frequent pressure checks are not to be made. After checking the tyre pressures do not forget to replace the valve cap which in addition to the valve body ensures an airtight seal.
Valve cap A valve cap is essential to ensure a correct airtight seal. In fact, at high speed, the valve body can be pushed in by simple centrifugal force. This leads to a loss of pressure and the risk is eliminated simply by fitting a valve cap.
These recommendations apply to tyres for use on the road. On a track and for racing in general there are special recommendations for this type of use.
Manufacturer tyre pressures are carefully arrived at and are safe and effective, however the possibility exists that on rare occasions they can prove to be less than perfect. If the tyre starts to exhibit any signs of uneven or abnormal wear when using recommended tyre pressures then seek expert advice.
Riding with underinflated tyres may result in complete tyre failure and subsequent loss of control of the vehicle.
Useful tips
Check tyre pressure every 2 weeks and when cold (a tyre that has not run for at least 2 hours or has run for less than 3 km at a reduced speed).
Adhere to the pressure recommended by the vehicle manufacturer regularly checking that this is proving suitable for your particular use of the bike.
A tyre should never be deflated when hot.
After checking the tyre pressures do not forget to replace the valve cap which in addition to the valve body, ensures an airtight seal.
Inflation with nitrogen does not mean that frequent pressure checks are not to be made.
If a check is made after use, it will be made on a hot tyre. Since pressure increases with the temperature, a tyre should never be deflated when hot.
