- Lubricate Beads: Apply a suitable tire mounting lubricant to the tire beads and rim flanges.
- Mount Tire: Carefully mount the tire onto the rim using appropriate tire mounting equipment. Avoid damaging the tire beads.
- Inflate: Inflate the tire slowly and carefully to the recommended operating pressure, ensuring the beads seat properly. Never exceed the maximum pressure indicated on the tire sidewall.
- Check for Leaks: After inflation, check for any air leaks around the bead area.
Note: Refer to your equipment's owner's manual for specific tire pressure recommendations and installation procedures.
5. Operation and Usage
The OTR Grassmaster tire is designed for optimal performance on turf and lawn surfaces. Adhering to proper usage guidelines will extend tire life and maintain equipment efficiency.
- Maintain Correct Pressure: Always operate the tire at the recommended inflation pressure for your equipment. Check pressure regularly, especially before use.
- Avoid Overloading: Do not exceed the maximum load capacity specified for the tire and your equipment. Overloading can lead to premature wear and tire failure.
- Smooth Operation: Avoid sudden starts, stops, and sharp turns, which can cause excessive wear and damage to both the tire and turf.
- Surface Considerations: While designed for turf, avoid prolonged use on abrasive surfaces like concrete or asphalt, which can accelerate wear.
6. Maintenance
Regular maintenance is essential to ensure the longevity and safe operation of your OTR Grassmaster tires.
- Tire Pressure: Check tire pressure weekly, or before each use, using an accurate gauge. Adjust to the manufacturer's recommended pressure.
- Visual Inspection: Regularly inspect the tire for any signs of damage, such as cuts, cracks, bulges, or embedded objects. Remove any foreign objects carefully.
- Tread Wear: Monitor tread depth. Replace tires when the tread is worn down to the wear indicators or when traction is significantly reduced.
- Cleaning: Clean tires with mild soap and water to remove dirt, debris, and chemicals that could degrade the rubber.
- Storage: When not in use for extended periods, store tires in a cool, dry place away from direct sunlight, heat sources, and chemicals.
