Change of Tyre

€
DANGER! If it is time to change tyres, it is recommended to leave this job to a specialist and follow the rules below.
Some mounting instructions are usually printed on the tyre itself.
Failure to understand the mounting instructions will result in a bad seating of the tyre on the rim, and it could cause
the tyre to burst leading to serious injury or death!
Never mount or use damaged tyres or rims! Use of a damaged, ruptured, distorted, welded or brazed rim is not
allowed!
Mounting Instructions
• Always clean and inspect the rim before mounting a new tyre.
• Always check that the rim diameter corresponds exactly to the rim diameter moulded on the tyre.
• Always inspect the tyre inside for cuts, penetrating objects or other damages. Repairable damages should be repaired
before installing the tube. Tyres with non-repairable damages must never be used.
• Always inspect the tyre inside for dirt or foreign objects. Remove this before installing a new tyre tube.
• Always use new tubes of recommended size. When fitting new tyres, always fit new tubes. Do not use tubes for
tubeless tyres.
• Before mounting, always lubricate both tyre beads and rim flange with approved lubricating agent or equivalent anti-
corrosion lubricant. Never use petroleum based greases and oils, because they may damage the tyre. Using the
appropriate lubricant will prevent the tyre from slipping on the rim.
• Always use specialised tools for mounting the tyres as recommended by the tyre supplier.
• Make sure that the tyre is centered, and that the beads are perfectly seated on the rim - otherwise tearing of the bead
wire may occur.
• Inflate the tyre to 1-1.3 bar (14.5-19 psi), then check whether both beads are seated perfectly on the rim. If any of the
beads do not seat correctly, deflate the assembly and re-centre the beads, before starting inflation of the tyre.
If the beads are seated correctly on the rim at 1-1.3 bar (14.5-19 psi), inflate the tyre to a maximum of 2.5 bar (36 psi),
until they seat perfectly on the rim.
• Never exceed the maximum mounting pressure moulded on the tyre!
• After mounting the tyres, adjust the inflation pressure to the operation pressure as recommended.
