Tyre Safety Tips

  • Tyre Selection

    The choice of a tyre that does not strictly conformto the original equipment specifications for a particular bike must be validated by a professional technician.

    Never use a tyre that is not inflated to the correct pressure, in excess of its indicated speed rating, or with a load that exceeds its load index.


    Tyres must be inspected on a routine basis for irregularwear patterns, which can be an indication of incorrect inflation pressure, overloading or mechanical problems. An underinflated or overloaded tyre that is ridden for a prolonged period may suffer irreversible damage that can have serious consequences, even if the tyre is returned to correct inflation pressure.

    Tyres should be inspected regularly, with particular attention paid to:

    • the tread area, to detect the presence of debris, cuts, deterioration or irregular wear patterns;
    • sidewalls, to detect impact damage (from potholes or kerbs), cuts, cracking or abnormal deformation;
    • the bead area, noting any trace of abrasions or rim damage.
    • If you suspect any problems, your tyres should be inspected internally and externally by a professional technician.
  • Wear

    The primary function of the tread is adhesion with the road. As tyre wear progresses over time, the tyre's ability to evacuate water deteriorates; consequently, you should reduce speed on wet roads. Remember to check regularly for tyre wear, by observing tread depth and uniformity of the wear pattern.

    A Michelin Man figure on the shoulder of Michelin tyres shows the location of the tread wear indicators situated in each of the main grooves of the tread.

    These indicators are small raised areas at the bottom of the grooves of the tread pattern.

    If the surface of the rubber is at the level of these raised areas, the tyre is most likely very close to the safe limit, or could even be below it.

    Factors affecting wear: A tyre's durability is dependent on several major factors.

    • Some are within the rider's control, such as inflation pressure, loads carried, vehicle speed and riding style (braking and acceleration).
    • Others are beyond the rider's control, and require adaptation of one's riding style: frequency of corners, type of road surface, ambient temperature.

    Remember that mechanical problems can also cause premature wear, including warped rims, worn suspension components, loose steering head bearings and/or frame misalignment.

    Any one of these factors can have a detrimental effect on tread life; a combination of several factors will cause significant wear.


    Correct inflation is essential to the tyres' safety, comfort and durability. Maintaining the bikemanufacturer's recommended inflation pressures has a positive effect on handling characteristics. It is also amajor influence on the motorcycle's handling, both in a straight line andwhen cornering, even atmoderate speeds and under braking.

    Riding on underinflated tyres can cause premature wear, irreversible damage to the casing and, possibly, a catastrophic deflation. Tyres lose air gradually. It is essential to check pressure every 15 days, when the tyres are cold.

    If the pressure is checked during or after a ride, the tyres will be hot, which will increase the indicated pressure.Never bleed air froma hot tyre. If the pressure reading is lower than the recommended pressure, air must be added to the tyre. Keep in mind that the indicated pressure of a hot tyre can be asmuch as 0.3 bar higher than the recommended cold pressure. After checking pressures, don't forget to reinstall the valve cap, which provides added protection for the valve mechanism.

  • Mounting / Balancing / Demounting

    The mounting and demounting of tyres should be undertaken only by a professional technician; improper handling of the tyre can damage it and put your safety at risk. When replacing a tyre, the installer must confirm the following:

    • that the replacement tyre is the correct size, as specified by themotorcycle manufacturer;
    • that the speed rating and load index of the replacement tyre are correct for the motorcycle;
    • for certain motorcycles, the manufacturer specifies a particular brand and model of tyre. Always refer to the ownersmanual or the tyremanufacturer's fitment guide for confirmation, or consultwith a dealer that sells the brand ofmotorcycle in question.

    The valve stem should be replaced whenever a tyre is installed, as the valve is essential to ensuring that the tyre is airtight. It is illegal to ride on a public highway with slick tyres or any other tyres that are marked NHS (Not for Highway Service) or "FOR COMPETITION USE."


    In the event of a puncture, only a professional tyre dealer has the expertise to conduct the internal and external inspections necessary to determine whether the tyre is repairable.

  • Break-in

    During the first 100km of operation after new tyres have been installed, the motorcycle should be ridden at moderate speed, and cornering angles should be increased progressively, until the tyre reaches its optimal performance.


    During the first few kilometres of each ride, ride at moderate speed until the tyres achieve operating temperature and optimal grip.

  • Mixing Tyres

    All recommendations and precautions are based on equipping the motorcyclewithMICHELINtyres both front and rear.

    Unless specifically recommended by Michelin, bias-ply and radial tyres should not be combined on one motorcycle, to prevent unstable handling.

    Handling & Storage

    Tyres must be stored in dry, ventilated and temperature-controlled conditions, protected fromdirect sunlight and inclement weather.

    • Away from all chemicals, solvents or hydrocarbons, which can adversely affect the rubber mixture.
    • Away from sharp objects that can puncture the tyre, including metal, wood or other potential hazards.
    • Away from heat sources or electrical devices.
  • Handling Michelin Bibmousse

    • MICHELIN BIB-MOUSSE is intended specifically for off-road competition use, exclusively with MICHELIN tyres. Use of MICHELIN BIB-MOUSSE with other brands of tyres is not advised.
    • It is marked NHS (Not for Highway Service). Consequently, motorcycles equipped MICHELIN BIB-MOUSSE should never be ridden on the highway.
    • MICHELIN BIB-MOUSSE should not be stored for long periods at temperatures above 30Û«Û«C, and temperatures above 40Û«Û«C should be avoided entirely.
    • The maximum service life of MICHELIN BIB-MOUSSE is six months from the date of initial installation.
    • A new MICHELIN BIB-MOUSSE simulates a pressure equivalent to 0.9bar. Over time, this pressure decreases, indicating the need for replacement.
    • The durability of MICHELIN BIB-MOUSSE may vary considerably, depending on the type and severity of use. For example, durability in motocross use will be less than in enduro use.
    • Before riding at high speeds for long periods, the MICHELIN tyre and BIB MOUSSE should be warmed-up gradually.
