How to maintain Chengli special car tires?
♦ Inspection of cracks and patterns in specialized vehicles
Regularly inspect the surface of specialized car tires for cracks, deformations, and other defects. If any are found, the tires should be replaced in a timely manner. Check the tread depth of special vehicle tires. If the tread wear reaches the wear limit (the tread depth of passenger cars and trailers must not be less than 1.6 millimeters; the tread depth of other vehicle steering wheels must not be less than 3.2 millimeters, and the tread depth of other tires must not be less than 1.6 millimeters), they must be replaced.
♦ Check the air pressure of specialized vehicles
The air pressure of special car tires should be inflated according to the regulations of the car manufacturer. The air pressure of special car tires should be checked regularly. Excessive or insufficient air pressure can cause abnormal wear and tear of the tires. Excessive air pressure can cause excessive wear in the middle of the tire; If the air pressure is too low, it will cause excessive wear on both sides of the tire. In addition, incorrect tire pressure in specialized vehicles can also cause reduced ride comfort, heavy steering, brake deviation, and other malfunctions.
♦Check the expiration date of specialized vehicles
When the special car tires have been used for more than 6 years, regardless of whether the car tires are intact or not, they still need to be replaced. When conducting secondary maintenance or driving a distance of 10000km, the car tires should be cross rotated according to regulations to ensure even wear of all tires and prolong the service life of specialized car tires as much as possible.
♦Timely replace specialized car tires
When installing car tires on specialized vehicles, tires of the same specification, size, pattern, and number of cord layers should be installed on the same axle. When replacing specialized car tires, it is best to replace all tires at the same time, at least in pairs. The replacement of the steering wheel (front wheel) must use new tires, and it is never allowed to replace worn old tires.
♦Pay attention to parking special vehicles
When parking a special vehicle, it is also important to protect the tires and avoid parking them on roads with large, sharp, or sharp obstacles. In addition, it should be avoided to park together with petroleum products, acidic substances, and other materials that affect rubber deterioration as much as possible.
♦ Treatment of Special Purpose Vehicle Tire Heating
Special purpose vehicle tires are prone to overheating and increased air pressure during summer or high-speed driving. At this time, the vehicle should be parked to dissipate heat, and deflation, pressure reduction, or water splashing to cool down are strictly prohibited.
♦Check the tread of specialized car tires
Regularly inspect the tire tread of specialized vehicles for any punctures and for any stones stuck between the two wheels. Remove the stones embedded in the tire and find small holes on the tread. Fill them with rubber to prevent sand and mud from entering the curtain layer and causing voids.
