Store tires clean and away from heat, light, ozone or hydrocarbons. Avoid prolonged exposure of tires to direct sunlight. Avoid any contact with grease, gasoline, volatile solvents or other agents that can damage the rubber. Avoid horizontal storage of tubeless tires, only small tires can be stored horizontally (max. 6 months). If tires are stored horizontally, they must be placed tooth-to-tooth. If the tires are stored mounted on the rim, reduce the inflation pressure. Make sure there is no water or moisture inside the tire. Never store tires in direct contact with the ground for long periods of time. For safety reasons, tires can only be repaired by professionals using the correct methods and tools. When loading a tire, it is necessary to take into account the relationship between speed, inflation pressure and the load capacity of the tire. (see also the online Pressure Calculator on our website). Overloading causes premature tire failure. Use technical documentation and inflation charts that define loads and inflations for different operating speeds. Underinflation not only causes the tire to run incorrectly, but also the separation of the pads, or other damage to the tire pads. Overinflation increases tire hardness and reduces impact resistance, leading to damage to the tire liners.

Tire mounting and dismounting can be dangerous and should only be performed by trained and qualified personnel using the correct tools and work procedures. Failure to properly follow these procedures may result in misfitting the tire on the rim, resulting in the destruction of the tire with explosive force that could result in serious injury or death. Make sure the rim, tire and tube are compatible. Check that the tire 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 tires on rims with cracks, severe deformation, signs of welding repairs, etc. Carefully inspect the inside as well as the outside of the tire to identify any damage. If the extent of damage does not allow for repair, the tire should be scrapped. When installing with a tube, always use the correct new tube and insert for the given dimension. To mount tubeless tires on tubeless rims, always use a new tubeless valve. Lubricate the rim and tire beads before mounting. Use only a suitable lubricant that will not destroy the tire (never use silicone or petrol-based lubricants). We recommend vertical mounting. In the case of horizontal installation, it is necessary to check whether the bottom foot is properly seated. Place the tire on the rim opposite the opening for the valve (observe the direction of rotation indicated by the arrows). Using the mounting lever, gradually slip the first bead over the edge of the rim. Subsequently, insert a slightly inflated tube, sufficiently treated with a slide (if it is mounted), into the shell. Position the valve and lightly secure it with the circlip. Put on the second foot, work your way up to the valve. To properly seat and center the casing, remove the inner valve insert. Inflate slowly and check the correct seating of the tire bead. Make sure the shell foot has not pinched the core. Keep a safe distance during inflation, always use a safety cage, if possible attached to the wall or with a safety chain. During the reading of the pressure, make sure that no part of your body is in the possible trajectory of the internal parts of the valves or its cap. It is recommended to use a suitable device to limit the inflating pressure. Use a compressed air filter and dehumidifier to remove moisture and dust. If the shoes are not seated properly, bleed air, re-lubricate and inflate. Repeat this operation until the feet fit correctly. If all the previous operations were done correctly, put on the inner valve insert. Inflate the tire according to the load. Make sure the valve does not touch the rim, brake drums and other mechanical parts. Removal Never attempt to remove the beads of an inflated tire. Always remove the inner valve insert. Check before dismounting that the tire is completely deflated. Never use tools that can damage the rim or tire beads.
