Tires for motorcycle are an important part of motorcycles, and unlike other parts, tires for motorcycle have many functions. Motorcycle tires are essential components for motorcycle work.
Tires for motorcycle are an important part of a motorcycle that is easily overlooked. Its correct use and function will directly affect the driving performance of the vehicle, and even involve driving safety.
This article will share the classification of tires and the use and maintenance of tires for motorcycle. Great electric motorcycle manufacturers in china use different tires depending on the model.
The role of tires for motorcycle
Supports the weight and load of the car
To support the weight of the car body, personnel, luggage and so on, mainly using the air volume and pressure in the tire to support the weight and load of the car body, so it is very important to maintain the appropriate air pressure.
Convey driving and braking power
In order for the car to move forward or stop, tires for motorcycle need to transmit the power of the engine and brakes to the road surface. This is mainly due to the friction of tire rubber. When the tire limit is exceeded when the tire is exceeded by rapid start or emergency braking, it is easy to cause the car to idle and skidd, which is very dangerous.
Cushion the impact of the road surface
This is known as “driving comfort” and softens bumps caused by uneven surfaces. This function is mainly through the amount of air and pressure in the tire, the elasticity of the rubber and the elasticity of tire structure. Therefore, the tire pressure of tire is too high or too low. Please maintain the appropriate tire pressure.
Change and maintain the direction of travel
The motorcycle is controlled to turn in the direction it wants to go or keep it in a straight line. This function is mainly performed through the friction and elasticity of the tire rubber and the robustness of structure.
Once you turn too fast and exceed the tyre limits, you won’t be able to go in the direction you want to turn. It is very dangerous, so please pay attention to speed when riding.
Classification of motorcycle tires
Composition structure
It can be divided into two categories: tubeless and tubeless, among which tires for motorcycle with tubes have been slowly marginalized, and tubeless tires have become mainstream.
Material function
It is divided into three categories: ordinary tires, semi-hot melt and full hot melt, and their main difference is that the functional properties of grip and durability are different.
Among them, semi-hot melt tires have become a trend in the market because they can better balance the two. While full hot melt tires will be more likely to appear on some functional models, channel motorcycles will use ordinary tires due to cost and durability considerations.
Pattern classification
If we cannot distinguish the material and actual effect of the tire with the naked eye, then the pattern will be a very intuitive display of different tires, in order to meet the grip needs of different use scenarios.
Specific model
At this stage, the general standard of motorcycle tires, the basic model will have three sets of numbers, which are matched with the wheel size.
Motorcycle tire tread
There are various grooves and notches on the surface where the tires are in contact with the road, which are called treads, and the following describes the tread of typical tires for motorcycle.
● Ribbed type
Ribbed tread refers to grooves around the tire and has the following characteristics:
Ribbed type
Reduces the likelihood of tire slippage and noise (squeaking).
Provides high maneuverability and stability for driving on paved roads.
It reduces the possibility of tire slipping and has high handling and stability, so it is suitable for use as a front tire.
Absorbs vibrations from the road surface (tire vibration) and reduces noise.
Low traction makes it unsuitable for use as a rear tire.
● Block type
The lumpy tread consists of individual small pieces with the following characteristics: Suitable for driving on uneven roads or sand like electric dirt bikes.
Block type
● Ribbed block
This ribbed block tread is a combination of ribbed and block tread with the characteristics of two types and is used in medium and large motorcycles.

Motorcycle tire functional construction
Tubeless tires
On its inner wall there is an airtight layer, forming a one-piece structure. This inner liner can be used as an alternative to an inner tube. The bead prevents air from leaking out of tires for motorcycle.
Tread
Parts where the tire and the ground are in contact can protect the tire cushioning layer and carcass from wear and external damage to the motorcycle tyre. In addition, tires for motorcycle have different tread patterns on the surface, each suitable for a specific purpose.
The tread also removes water from slippery roads, preventing the electric motorcycle from slipping when the driving or braking force is applied.
Buffer layer
The buffer layer is located between the tread and the carcass, and they absorb vibrations on the carcass, preventing the tread from separating from the carcass.
Carcass
One of the structures that make up the tire is the skeleton of tire. The tire frame is formed by stacking several layers of cord (carcass cord) on top of each other. The role of the carcass is to withstand the loads and vibrations applied to the tire and the air pressure inside the tire.
Side walls
The part that is more external than the tread and does not touch the tire side on the ground. The function is to protect the carcass and will not come into contact with the road surface.
When riding a motorcycle, the sidewall bends more than any other part of tires for motorcycle, and information such as tire size, manufacturer name, and tire name are indicated on the sidewall.
Wear indicator wire
When the tire is mounted on the rim, the wear indicator line is used to check that the bead is stuck in the correct position.
Bead
The bead supports both ends of the carcass cord to secure the tire to the rim. Consisting of a bundle of steel wire (piano wire), there will be some clearance between the rim and the bead so that the bead can hold tightly against the rim when the tire is inflated.
Innerliner
An innerliner is a layer of rubber, the innermost layer of tubeless tires, which can be used as an alternative to tubes, and the innerliner has the function of maintaining tire pressure.
Tire pressure is rarely checked when using motorcycles. Tires for motorcycle are overdue, and many counterfeit, inferior, and copied tires for motorcycle in the accessories market will cause potential safety hazards.
The specifications of the tire are indicated by a set of numbers plus letters, printed on the side of tires for motorcycle. The first number indicates the cross-sectional width of tires for motorcycle.
The second number represents the aspect ratio. The third is the letter, which indicates the tire structure. The following numbers refer to the rim diameter. The last number is a letter, representing the load factor and speed class, respectively.
When to change tires for motorcycle
Tread wear is close to the wear mark
Any brand of tire will have a wear mark at the bottom of the tread groove. The wear mark height on general car tires is 1.6 mm, and the wear mark height on load tires is 2.4 mm.
Tread wear is close to the wear mark
Some people think that as long as the tire is not broken, even if the tire pattern is almost worn out, it will continue to be used.
Such old tires are actually very dangerous, when encountering slippery roads, the tread pattern can not completely drain the stagnant water under the tires, which can easily cause the motorcycle to lose control.
Cracks or bulges in the tire
In the process of daily use of the car, tires for motorcycle may be pricked by foreign objects, or accidentally hit the road, these unexpected situations can cause tire damage.
Tires appear bulging
Damage to motorcycle tires includes cracked treads, bulging treads, missing tread rubber, severe sidewall wear, and tires repeatedly pricked by foreign objects. Especially bulges, tires can be at risk of bursting at any time.
As long as this damage is found in the tire, it is necessary to go to a professional maintenance station and requiry like Benlg as soon as possible to check and replace it on time.
Tire life expires
The service life of the tire is usually about 5 years, after which the tire will begin to age. The main manifestation of tire aging is hardening of the surface, followed by cracks. Aging tires will lose their elasticity, and if they continue to be used, they will cause deformation of the tread and there is a risk of puncture.

How to make motorcycle tires more durable
Avoid burning tires in situ. Burning tires cause severe local tire wear and shorten service life.
Avoid bumps and getting into potholes. If the air pressure is insufficient, safety problems are likely to occur.
Maintain proper tire pressure.
Suitable tire pressure can ensure that the ground area of tires for motorcycle is uniform, reducing unnecessary wear. Therefore, car owners should develop the habit of regularly checking tire pressure and keep abreast of the tire pressure condition.
Tire pressure can be tested by a professional repair shop, or you can buy a tire pressure gauge to test it yourself, and the tire pressure standard can refer to the tire pressure label of the vehicle.
Do not lower the tire pressure in summer
Many people think that with high temperatures in summer, lowering tire pressure can avoid punctures. In this way, the contact surface between the tire and the ground will increase, the friction will increase, and the tire wear will be accelerated.
And it will cause the tire temperature to rise faster and make it easier to blow out. Therefore, it is still necessary to maintain normal tire pressure in summer.
How to choose the best tires for motorcycle
The maximum numeric value
Each tire will have its own maximum air pressure value KPa, maximum load capacity kg, and limit speed km/h, which is the red line that the tire cannot touch, otherwise there will be the possibility of a puncture (the tire shoulder will be marked).
Hierarchical standards
There are usually 4 levels, 6 levels, 8 levels, the higher the level, the better the material of the tire. The rear tire cannot use four levels, so be careful when choosing.
Tire orientation
It will have its own normal rotation direction, even ordinary tubeless tires will have this characteristic. If we do not pay attention to the direction of assembly, then its grip will be reduced, and it will also affect the actual drainage effect. Therefore, be sure to follow the direction of the arrow or pattern on the side of tires for motorcycle to carry out the correct installation.
Tap the tire
There will be a yellow dot on the sidewall of the motorcycle tyre, which is the lightest position of the entire tire, which must be aligned with the valve of the hub.
Because the hub valve is the thickest place in the entire hub and the heaviest position, when these two points completely coincide, the error will be smaller when the entire wheel is dynamically balanced.
Operating temperature
The temperature can neither be too low or too high, low has insufficient grip performance, high will have the possibility of puncture.
Select criteria
When choosing, in addition to maintaining the same model of the original car, combined with actual needs, consider its grip and cost performance.
Usually wear-resistant tires will not have too good grip, because its own rubber will be hard. And the tires with large patterns do not show too good comfort and noise control.
At the same time, tires with good grip do not have too good wear resistance. At this time, comprehensive consideration is required. Take the top 10 electric motorcycle manufacturers into consideration for their products are in high quality.
Conclusion
The choice of tires is very important, regardless of the appearance of the motorcycle, tires are the foundation of support and walking, and the cornerstone of safety.
The real performance of tires varies greatly, making people not know how to choose. Different brands and different applications of tires will have big differences in performance. Hope this article can provide some help and reference.
