LONG HAUL ROAD

FAQ：

How to maintain long haul road tires to maximize their service life for fleets?

Answer: Fleet maintenance of long haul road tires should focus on four points: first, keep the tire pressure at the manufacturer's recommended value, and avoid underinflation (causing sidewall heat accumulation) and overinflation (reducing grip and increasing wear); second, rotate tires every 10,000-15,000 miles to avoid uneven tread wear caused by long-term high-speed driving; third, regularly check the tread for cuts and bulges, and remove stones in the grooves in time; fourth, avoid sudden acceleration and emergency braking on highways to reduce abnormal tread wear.

What is the optimal tire pressure for long haul road tires under full load high-speed conditions?

Answer: Under full load high-speed conditions (80-100km/h), the optimal tire pressure for heavy-duty long haul road tires (295/75R22.5, 11R22.5) is 8.0-8.5 bar; for light-duty long haul road tires (7.00R16, 7.50R16), the optimal pressure is 6.5-7.0 bar. The pressure can be appropriately reduced by 0.2-0.3 bar in high-temperature seasons to avoid excessive internal pressure caused by tire heat generation.
