Fitting and removing tyres can be dangerous and should only be carried out by trained and qualified personnel using the correct tools and working procedures. Failure to follow these procedures may result in incorrect fitting of the tyre to the rim and subsequently cause the tyre to be destroyed with explosive force, which can cause serious injury or death. Make sure the rim, tire and tube are compatible. Check that the tyre is suitable for the equipment/machine. Use only rims recommended or approved by the tire manufacturer. Always use only the correct special equipment and tools. The rim must be clean and in perfect condition (not damaged etc.), if necessary clean the rim with sandpaper. Under no circumstances mount tyres on rims that are cracked, seriously deformed, have welding repair marks, etc. Carefully inspect the inside as well as the outside of the tyre to identify any damage. If the extent of the damage does not allow repair, the tyre should be devalued. If mounting with a tube, always use the correct new tube and liner for the size. For mounting tubeless tires, on tubeless rims, always use a new tubeless valve.Lubricate the rim and bead before mounting. Use only a suitable lubricant that will not destroy the tire (never use silicone or gasoline based lubricants). Vertical mounting is recommended. In the case of horizontal mounting, it is essential to check that the bottom bead is seated correctly. Fit the casing onto the rim opposite the valve hole (respect the direction of rotation indicated by the arrows). Using the mounting lever, gradually slide the first bead over the rim rim rim rim. Then insert a lightly inflated inner tube, sufficiently treated with a slip joint (if fitted), into the rim. Position the valve and secure it lightly with the retaining ring. Fit the second foot, working in sequence so that you end up at the valve. Remove the inner valve liner to seat and center the shell properly. Slowly inflate and check for proper seating of the casing foot. Ensure that the casing foot has not pinched the inner tube.Maintain a safe distance during inflation, always use a safety cage, preferably attached to a wall or safety chain. During pressure readings, make sure that no part of your body is in the possible trajectory of the valve internals or its cap. It is recommended to use a suitable device to limit the inflation pressure. Use a filter and dehumidifier for the compressed air necessary to remove moisture and dust. If the feet are not seated properly, bleed, re-prime and re-inflate. Repeat this operation until the feet are seated correctly. If all previous operations have been performed correctly, fit the valve liner. Inflate the tyre according to the load. Ensure that the valve does not touch the rim, brake drums or other mechanical parts. Disassembly Never attempt to remove the bead of an inflated tyre. Always remove the valve inner liner. Check that the tyre is completely free of air before dismounting. Never use tools that may damage the rim or tire beads.
