How To Classify Motorcycle Tire Molds

1. Composition structure. Motorcycle tires can be divided into two categories: inner tube and vacuum tire. Among them, inner tube motorcycle tires have been gradually marginalized, and vacuum tires have become the mainstream.
2. Material function. From the material point of view, motorcycle tires can be divided into three categories: ordinary tires, semi-smelt tires, and full hot melt tires. The main difference between them is the different functional properties of grip and durability.
Among them, semi-smelt tires have become the new darling of the market because they can better take into account both. Full hot melt tires are more likely to appear on some functional models. Tonglu motorcycles will use ordinary tires due to cost and durability considerations.
3. 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. At present, there are many tire patterns, among which the common ones are road tires, turtleback tires, off-road tires, etc. Although they are called differently and the layout of the pattern will also be different, they are all to meet the grip requirements in different usage scenarios.
4. Specific models. According to the general standards of motorcycle tires at this stage, there are three sets of numbers that make up the basic models, such as 140/70-17, where the first 140 is the tread width, 70 is the aspect ratio, we can simply understand it as the height of the tire shoulder after inflation, and 17 is the tire diameter, which is matched with the wheel size.
1. Maximum value. In daily life, we often hear old drivers say to fill me with two and a half air pressures, but in fact each tire has its own maximum air pressure value KPa, maximum load capacity kg, and maximum speed km/h. This is the red line that the tire cannot touch, otherwise there will be a possibility of a blowout (the tire shoulder will be marked). In addition, there will be a level standard for tires, usually there will be 4-level, 6-level, and 8-level differences. The higher the level, the thicker the material of the tire, and the rear tire cannot use four-level, so you must pay attention when choosing.
2. Tire direction. Each tire has its own normal rotation direction. Even ordinary tube-type tires have this characteristic. If we do not pay attention to the assembly direction, its grip will be reduced and the actual drainage effect will be affected. Therefore, it must be installed correctly according to the direction of the arrow or pattern on the side of the tire.
3. Light tires. There will be a yellow dot on the sidewall of the motorcycle tire. It is the lightest position of the entire tire. This position must be aligned with the valve of the wheel hub, because the valve of the wheel hub is the thickest part of the entire wheel hub and the heaviest position. When these two points are completely overlapped, the error of the entire wheel will be smaller when it is dynamically balanced.
4. Working temperature. The tire also has its own working temperature. This temperature cannot be too low or too high. If it is too low, there will be insufficient grip. If it is too high, there will be a possibility of a tire blowout. Therefore, some riders are not playing cool by grinding tires, but using a relatively extreme way to quickly reach the appropriate working temperature of the tire to exert its normal performance.
5. Selection criteria. Since tires have so many secrets, in addition to considering keeping the same model as the original car (changing the model at will will not be able to pass the annual inspection), we must also consider its grip and cost-effectiveness in combination with personal actual needs.
Usually, wear-resistant tires will not have very good grip, because the rubber itself will be hard; and tires with large patterns will not show very good comfort and noise control; at the same time, tires with good grip cannot have very good wear resistance; at this time, we need to consider comprehensively. Therefore, for road vehicles, if you want good grip, wear resistance and practicality, you should choose tires with relatively larger patterns and higher levels in road tires. For models that often run on non-paved roads, you should still consider all-terrain turtleback tires. Semi-smooth tires for pure fun models will be a good choice. Of course, if you are not short of money, you can go directly to full hot melt.
