Trial tip
The design of Trial tyres makes them tricky to mount. You run the risk of breaking bead wires if you press too hard. Carefully adhere to the fitting instructions for insertion of the rim hooks (lubricate, firmly hold the bead on the opposite side in the rim hollow - do not exert excessive force on the bead). To inflate, position a rubber ring between the tyre bead and rim or use a firmly tightened strap on the tyre crown to enable initial pressurizing pressurising.
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: MICHELIN Enduro, Desert Race > size designation based on the width of the tyre measured at the tread level
- New classification: MICHELIN StarCross, Tracker, AC10, Trial > size designation based on the width of the tyre measured at sidewall level
For example : a 140/80-18 Enduro tyre corresponds to a 120/90-18 Motocross tyre (see our table below).
