Tyres need the right amount of air to ensure safety and longevity


Following the manufacturer's recommendations for tyre inflation has a positive effect on the bike's performance. Tyres gradually lose air so it is essential to check tyre pressure before you set out. If you check your tyres during your journey, you will be checking 'warmed up' tyres. In effect, the pressure builds up whilst on the road, so you should never let down a tyre that has just been used


If the tyre pressure is below that recommended by the manufacturer, you should top up the air. The pressure should be more than 0.3 bars higher than the recommendation for a tyre starting from cold.


Once you have checked the tyre pressure, don't forget to replace the cap on the valve to ensure no water gets in to the core of the valve. We recommend you change the valve and cap every time you replace a tyre as it is an essential part of the seal.


Recommended pressures

These are the tyre pressures recommended by Michelin depending on the terrain, the weather conditions, the power of the bike and the type of control:


Michelin Bib Mousse

MICHELIN Bib Mousse, MICHELIN's off-road solution to a puncture!


Invented by MICHELIN and intended for Rally-Raid, Endurance and Cross bikes, here are some tips for using MICHELIN Bib Mousse:


MICHELIN Bib Mousse is lighter than a reinforced tube. With a pressure equivalent to 0.9 bar, it does away with the inconvenience of a puncture.


The maximum speed with a tyre using MICHELIN Bib Mousse is 130kph. It carries the letters NHS (Not for Highway Service). Consequently, a tyre with MICHELIN Bib Mousse should not be used on the public highway.


MICHELIN Bib Mousse should not be kept long term at temperatures above 30°C and it is best to avoid temperatures above 40°C altogether.


MICHELIN Bib Mousse can be used for a maximum of 6 months after application, much less with intensive use


The lifespan of MICHELIN Bib Mousse varies considerably depending on the intensity of usage and the discipline practised. For example, it will be much shorter for Motocross than for Endurance.


Before a fast session, Michelin recommend you warm up the tyre and the MICHELIN Bib Mousse at a moderate speed.


Apply Michelin gel every time you put on or take off a MICHELIN Bib Mousse, both new and used, to prolong its life and avoid excessive overheating.


Handling and storage

Your tyres should be kept somewhere ventilated, dry and temperate, out of direct sunlight and away from temperature extremes, all chemicals, and any solvent or hydrocarbon which might affect the rubber. They should also be kept well away from anything that might pierce the rubber (for instance sharp metal or wood) and away from direct heat or electrical charges.


Trial tip

The design of Trial back tyres makes then tricky to mount. There is a risk of damage to the spokes during the operation. You need to pay careful attention to the installation instructions with regards to the rim flanges (lubricate, hold the heel away from the rim and never use excessive force on the wheel.) When putting air in the tyre, place a circle of rubber between the heel of the tyre and the rim or use a tight belt at the top of the tyre to take the initial pressure.


Tyre wear

The tread provides most of the tyre's grip on the ground. With wear, the tyre's grip decreases. So remember to regularly check your tyres for signs of wear: visually check the depth of the tread and the uniformity of the wear. Tyre pressure also has a direct impact on wear.


Two possible classifications for the same tyre dimension

Careful! There are two classifications for the same tyre dimension.


Old classification: Enduro, Desert, Gamme 12 New classification: StarCross, AC10, Trial Light and Xlight


For the Enduro, Desert, S12XC and M12XC ranges the classification is determined by the width of the tyre at the tread.


As for the Star Cross, AC 10 Trial Light and Xlight ranges, the name is based on the width of the tire measured at the flanks.


So a 130 / 70-19 Cross Competition S12XC corresponds to a 110 / 90-19 Starcross 5.
