Motorcycle tire maintenance skills

1. Basic knowledge of motorcycle tires

 

Since you bought the car, the manufacturer has stipulated the nature of the tire, the inner diameter and the rim size of the wheel. However, tires are consumables. As long as the wheels turn, they begin to wear. The wear speed is related to many factors. The service life of the same tire is also different due to the different road surface, load, driving technology, maintenance and maintenance level. Therefore, when the tire is driven to a certain mileage, it should be replaced. Generally, the tire groove shall not be less than 2mm, otherwise, it will cause sideslip on the curve due to its poor grip, and there may be dangerous accidents such as tire burst when driving at high speed. These are related to the driver's life safety, so we should attach great importance to them.

 

If you want to roughly classify tires, they can be divided into inner tube tires and tubeless tires (vacuum tires commonly referred to by car repairmen). The principle of inner tube tire is to keep the air in the inner tube without requiring precise contact between the tire and the rim. Even if the air pressure is low, there is no need to worry about the tire falling off the wheel, resulting in air leakage. Therefore, inner tube tires are widely used in off-road vehicles and American street vehicles using rims and steel wires. The principle of tubeless tire is to seal the air in the carcass by using the special structure of the rim of the steel ring (RIM) and the edge of the tire. Even if the tire is stabbed by a foreign body, the air will not disappear immediately, and the repair of a flat tire is very convenient, so it is very popular with motorcycle friends. In recent years, tubeless tires have gradually been used on ordinary motorcycles. It can be seen that the two kinds of tires have their own advantages.

Generally, qualified tires are marked with specification, maximum load, inflation internal pressure, standard rim, trademark, manufacturer name and direction. For example, the specification 160 / 60-17 is marked on the original outer tire of the rear wheel of Longxin lx650 (Wuji), where the first 160 indicates that the width is 160mm; "/" The latter 60 represents the flat ratio (%), that is, the height is 60% of the width; "-" The rear 17 indicates that it is suitable to be installed on the rim diameter of 17 inches (1 inch = 2.54 mm). If some tires are not marked with the flat ratio, it means that the flat ratio is 100%, that is, the width is equal to the height.

 

2. Purchase of motorcycle tires

 

As motorcycle tires are consumables, changing tires has long been a common thing for motorcycle friends. Due to the different forces on the front and rear wheels, the wear of the rear wheel is always greater than that of the front wheel. Generally, you need to change a front tire only after changing two rear tires, or you need to change an outer tire only after changing several inner tires. So, how to choose a qualified tire? Maybe you have no way to start with the various tires in the motorcycle accessories market.

① When selecting a tire, its specification must not be wrong. Even if the tire width is narrow and the specification is right, it can be used. However, if the specification is wrong, it can either not be installed or it is too loose to use. This will not cause unnecessary economic losses.

 

② After determining the correct specification, we should consider the width of the tire. Xiaoxin believes that if the economy allows, we should try to buy a wider tire, because the contact surface between the wide tire and the ground is large and the grip is good, so that we can well transmit the driving force and braking force, give full play to the performance of the engine and improve the stability, comfort and safety of driving.

 

③ Finally, we have to look at the tread. The tread is still an important index to determine the tire performance. The shape of the tread determines its drainage and the ability to remove other sundries, as well as its grip performance. Therefore, it is very important to select the appropriate tread pattern. There are dozens of tread patterns for tires of the same specification. Generally, appropriate tread patterns should be selected according to the actual situation of motorcycle friends. If you often drive on mountains, mud roads, snow roads, ice roads and other roads, you should choose off-road tires with wide tire groove and deep tire groove pattern, because the tire groove is deep and wide. Under the rotation of the wheel, due to the action of centrifugal force, it is easy to drain water and other sundries, so that the tire can better contact the ground. If you often drive on the highway, you should choose a more compact tire groove, such as ring, arrow, etc. This kind of tire has a large contact surface with the ground when driving on the road, which can make it safer than other tires. Motorcycle friends with good conditions can choose high grip tires. Although this kind of tire has a high wear rate, it is definitely a good tire with high performance. It is a safe tire with very good drainage and adhesion.

 

3. Tire maintenance

 

After you have a qualified tire, you can let your good foal run fast. Perhaps, many motorcycle friends only pay attention to the maintenance of the engine and appearance, but ignore the maintenance of the tire, which shortens the service life of the tire and increases the consumption on it. Therefore, mastering some common sense of maintenance and repair can not only save costs, but also reduce many troubles caused by tire problems when driving.

 

According to statistics, the consumption and maintenance times of tires in the same period are related to personal driving skills, and the difference in consumption and maintenance costs can reach 10% ~ 30%. The maintenance and repair of tires can be discussed from two aspects: one is the road factor and the other is the human factor, but the decisive factor is still the human factor. Sometimes the road factor can not be avoided, such as sometimes having to go through ice stones, construction sites and garbage roads, resulting in puncture and puncture of tires. In the face of this situation, we can only drive carefully or detour as much as possible.

 

Riders who like to perform some driving skills, such as turning around in place, single wheel driving, emergency braking, drifting and cornering, tricycle turning up one wheel, etc. These practices are very harmful to the tire, which not only accelerates the wear of the tire, but also is very unfavorable to the engine. They should be avoided as far as possible. It is suggested that motorists develop good driving habits, which can not only save tires, but also prolong the service life of the engine. For example, the starting and braking shall be gentle; Be diligent in shifting gears when going uphill to avoid starting halfway; Don't be too fierce when crossing potholes; When parking, we should develop the habit of supporting the frame, so that the car can completely "reduce the load" when resting. These are effective ways to maintain the tires.

 

The last point is often ignored by Mo you. That is, the phenomenon of "tire eating". The so-called "tire eating" means that the degree of tire wear on the left and right sides of the tire is different. Common reasons are: the scales of the sprocket regulators on the left and right sides are different, the front and rear wheels are not in the same line, the front and rear axles are not parallel, and so on. If motorcycle users find that their car has tire eating phenomenon, they should find out the cause as soon as possible, make careful adjustment, and finally completely solve the problem of "tire eating", because "tire eating" is a fatal injury to motorcycle tires, and the wear rate is faster than that of other methods.

 

In addition, the maintenance of the tire is to add appropriate air pressure to the tire. If possible, the tire should be inflated in strict accordance with the air pressure marked on the tire, because the air pressure is directly related to the service life and performance of the tire. If the air pressure is found to be low, find out the cause of the air leakage. Is it a leak from the air nozzle or a slow discharge? If the air valve leaks, check whether the valve core leaks or other reasons. For slow inflation, a small amount of talc powder (about 30g) can be injected into the tire, which can solve the problem of slow inflation.

 

From the above, we can see the importance of tires on motorcycles. Therefore, it is necessary for every motorcycle friend to master certain maintenance and maintenance knowledge. It can not only prolong the service life of tires and reduce investment, but also reduce accidents and troubles. Why not?

 

Due to the light weight and high horsepower of the motorcycle, the weight of the vehicle is concentrated with the rear wheel due to the inertia of acceleration. In addition, the motorcycle has to escort the vehicle at a large angle in many corners. It can be seen how important the tire is to a motorcycle. Speaking of motorcycle tires, there are two important points: the essence of tires and tire pressure!
