Care and Service of Tires

Check tires daily for damage or noticeably low pressure.

At least every 50 hours of operation, check tire pressure. If tires contain liquid ballast, use a special air-water gauge and measure with valve stem at bottom.

A small puncture in a tubeless tire can be temporarily repaired without dismounting the tire, thus avoiding down time during a busy season.

Protect tires from exposure to sunlight, petroleum products, and chemicals.

Drive carefully. Try to avoid rocks and sharp objects.

IMPORTANT: A permanent repair should be made as soon as possible to prevent further tire damage.

NOTE: Tire pressures listed below may be higher than the tire pressures shown on the side of the tires.
