Bicycle manufacturers introduce the difference between vacuum tires and ordinary tires and the use of precautions
Tubeless tires are often called “low pressure tires”, “vacuum tires”, divided into radial tires and diagonal tires. Tubeless tires have high elasticity and wear resistance, and have good adhesion and heat dissipation performance. Especially radial tires, because the crown angle is zero, the amount of change in the vehicle at high speed is small, and can maintain good driving stability and less friction, which is conducive to the absorption of vibration shock and speed increase. Tubeless tires are much thicker than the general inner tube type tires, and the surface has a layer of high quality rubber, inflated appearance tension increases, forming a certain pressure on the inner surface, improving the self-sealing ability of the breach, once punctured, unlike ordinary car tires like gas in an instant all the drain, will last for a certain period of time, to protect the high-speed driving completely.
Tubeless tires require high manufacturing precision because the tires are sealed as one with the wheel rim. Most of them are die-cast aluminum integrated wheels, with high positioning between the tires and minimal radial runout of the wheels. The comfort and stability of motorcycles with tubeless tires are much better than those with ordinary tires.
- Several points to note in use
The required air pressure must be maintained.
Tubeless tires are made of high quality rubber, which is flexible and adaptable to a wide range of air pressures, so even if the tire pressure is high, there is no hard feeling like a regular tire. In addition to tires, tubeless tires generally do not deflate on their own, so use the air pressure gauge to check and maintain the required pressure when inflating, do not feel the same as ordinary tires to decide whether to fill the air.
Tubeless tires in use should also avoid being punctured by sharp and hard objects, puncture, avoid contact with acid, alkali, stained by oil will also accelerate the decomposition of rubber. The tires should be kept clean to prevent the rubber from aging and to prolong the service life.
Tubeless tires have good adaptability to asphalt and cement roads, even if there is water on the road, they can maintain strong adhesion and have good stability. However, they have little traction and poor stability on dirt roads, especially muddy ones. Motorcycles with tubeless tires are best used in urban areas and should not be driven on dirt roads in the suburbs.
- Cold patching of tubeless tires
A punctured tire can be repaired with a special repair tool. If the motorcycle repair department is not equipped to repair the tire, you can do it yourself with cold patching rubber by
Remove the wheel and peel off the tire. It is best to use a bamboo board to pry up one side of the tire, and then press both sides of the tire to the middle as much as possible to gently pick it up, taking care not to break the two edges of the tire.
After cleaning up the foreign matter in the break, use sandpaper to apply cold patching glue around the break (more can be applied, but only once) for 5 minutes – 7 minutes and then use a large piece of cold patching film to stick in the tire. If the speed of the car is high, you can cold patch the salty double layer to improve the strength of the repair, and stick two layers of cold patch film of the same size in the symmetrical position in the tire to keep the wheel balance.
After installing the tire, such as manual pumping, the beginning to be fierce, and strive to quickly fill up both sides of the tire and sealed, installed valve needle to play to the prescribed air pressure, and then tighten the valve needle. The last check, such as no air leakage can be installed and used.
