1. Before mounting, make sure that the rim, tire and inner tube are compatible, check if:
- The rim is compatible with load and pressure requirements
- The tire is suitable for the vehicle or machine
- The seat diameter of the rim corresponds to the seat diameter of the tire to be mounted (Example: Casing 18.4 R 30 Rim: DW16L x 30),
- Tire mounting is permitted on this rim
Warning: there are rims with 15.3” seat diameters, never install 15” tires on these rims. Similarly, for 16.1” and 16.5” diameter rims, never mount 16” tires.
2. On a rim that has already been used, before mounting: The rim must be clean and undamaged. Once inspected, clean the rim with a wire brush. Warning: Never mount a tire on a cracked or bent rim, or that shows signs of breakage, weld repair marks, etc.
3. If the tire is worn, carefully examine the outside and inside for any damage that needs to be repaired before installation. If the tire shows any damage or signs of wear that a specialist deems unrepairable, remove the tire.
4. When mounting with an inner tube, always use a new inner tube suitable for the tire (compatible tire sizes are marked on the inner tube). Do not mount an inner tube in a damaged, repaired or uneven rim. For tubeless mounting of a tubeless tire on a tubeless rim, fit a new tubeless valve each time the tire is mounted.
5. Use tools that are in good condition, that are clean and suitable for tires and rims (bead removers, levers, machines, etc.). For large or high volume tires, it is recommended to use a bead pusher or bead breaker (appropriate mechanical assistance) for mounting the second bead. Before mounting, lubricate the casing rim seals and the bulges (beads). Apply a thin layer of lubricant to the parts marked on the sketch. On the outside of the beads, the lubricant should be up to 3 inches higher than the rim flange. Only use products made for this purpose and not harmful for the tire: avoid hydrocarbon, silicone and antifreeze based products.
