4.2 Storage
When not in use for extended periods, store tires in a cool, dry place away from direct sunlight and harsh chemicals to prevent premature aging.
5. Troubleshooting
5.1 Loss of Air Pressure
- Cause: Puncture, improper bead seating, valve stem leak.
- Solution: Inspect for punctures and repair if possible. Re-seat tire beads or replace valve stem. Seek professional assistance if the leak persists.
5.2 Uneven Wear
- Cause: Incorrect tire pressure, misalignment of equipment, or worn suspension components.
- Solution: Ensure tires are inflated to the correct PSI. Check equipment for alignment issues or worn parts.
5.3 Difficulty Seating Beads
- Cause: Tire deformation from shipping, dry beads.
- Solution: Apply a tire lubricant to the beads and rim. Use a ratchet strap around the tire circumference to help push the beads outwards while inflating. If issues persist, professional mounting is recommended.
