Storage
- Keep the tyres clean and away from heat, light, ozone or hydrocarbon sources.
- Avoid prolonged exposure of the tyres to direct sunlight.
- Avoid any contact with grease, petrol, volatile solvents or other substances that may deteriorate the rubber.
- Avoid horizontal storage for tubeless tyres, only small size tyres may be stacked or stored flat. (maximum 6 months)
- When tyres are stored flat (horizontal), the position must be lug against lug.
- Reduce inflation pressure when tyres are stored fitted on rims.
- Ensure there is no water or moister inside the tyre.
- Never store tyres directly in contact with the ground for long periods.
Proper use of Tyres
- When loading tyres you have to consider the correlation between speed, inflation pressure and load capacity.
- Overloading results in premature tyre failure. Use the technical documentation and inflation tables which show the load and pressure figures for different operation speeds.
- Under-inflation results not only in incorrect tread wear but also in ply separation and eventually further damage to the ply.
- Over-inflation makes the tyre stiff and decrease its resistance against hits, leading to ply tear.
Repairs to Tyres
- For safety reasons, repairs should only be carrier out by specialists using the correct tools.
Repairs to Tyres
Demounting and mounting procedures can be dangerous, and should be performed only by trained and qualified staff, using proper tools and procedures. Failure to comply with these procedures may results in faulty positioning of the tyre on the rim, and cause the tyre to burst with explosive force leading to serious physical injury or death.
Fitting
- Make sure that the rim, the tyre and the tube are compatible.
- Check that the tyre is suitable for the machine. Use only rims recommended or permitted by the tyre manufacturer.
- Always use the proper specialized equipment and tools.
- The rim must be clean and in perfect condition (no damage etc). If necessary, clean the rim thoroughly with a wire brush. Never fit a tyre onto a rim that shows cracks, significant distortion, evidence of welded repair, etc.
- Thoroughly inspect the inside as well as outside of the tyre in orderto identify and damage which may be present. If the damage is considered to be beyond repair, the tyre should be scrapped.
- If fitting with a tube, always use the correct new tube and flap for the tyre size. For fitting tubeless tyres without tubes, on tubeless rims, always use a new tubeless valve.
- Before fitting, lubricate the rim and the beads. Use only a suitable lubricant that will not damage the tyre (never use silicone or petroleum based products).
- We recommend vertical fitting. In case of horizontal fitting it is impossible to see if the lower bead is correctly seated.
- Fit the tyre on the rim diametrically opposite to the valve hole (respect, if present, the rotation direction indicated by the arrows). With the help of a suitable lever and closely repeated applications, get the first bead over the rim flange. Then pose the lightly inflated talc coated tube (if fitted) inside the tube. Locate the valve, fitting the ferrule loosely. Fit the second bead, lever it progressively over the rim flange, finish at the valve.
- For seating the beads and centering of the tyre, remove the valve core. Slowly inflate the ensure correct seating of the beads. Ensure that the beads of not pinch the tube.
- During tyre inflation keep at a safe distance and always use a safety cage. If possible, fasten the tyre of the wall or use retaining chains. During pressure readings ensure that no part of body is within the possible trajectory of the valve mechanism or the caps. it is recommended to use suitable pressure limitation gauges. Use a filter and dehumidifier on the compressed air line to avoid introducing humidity or dirt. Never use a hammer to make a tyre bead seat by hitting it.
- Continue inflation. Make sure that you do not inflate beyond 2.5 Bar if the beads are not well seated and centered on the wheel.
- If the beads are not correctly seated deflate, lubricate and inflate again. Repeat these operations until the beads are correctly seated.
- When all the previous operations have been correctly done, refit the valve core. Set the pressure according to the load-see tables in technical data book.
- Make sure the valve does not touch the rims, the brake drums or the fixed mechanical parts.
Removing
- Never try to unseat the beads of an inflated tyre.
- Always remove the valve core.
- Let the tyre deflate. Check before unseating that the tyre is completely deflated. Never use tools that could damage the rims or the beads of the tyre.
