Motorcycle tire specifications are marked similarly to car tires, but there are also some special marking attributes. The basic specification markings include four dimensions: the outer diameter of the tire, the overall width of the tire, the height of the tire, and the diameter of the rim. Basic specification markings: The outer diameter of the tire, the overall width of the tire (including the tread width), the widest part of the tire; the height of the tire, the length from the bead to the center of the tire, and the diameter of the rim. Based on these four basic data, the tire will display the following specification markings: (overall width of the tire)/(aspect ratio: the ratio between the height and the overall width of the tire)-rim diameter. These data are not marked to the precise 1mm unit but are only roughly indicated. Meaning of the yellow dot marking: The common light point on domestic tires indicates that this part is the point with the lowest mass on the circumference of the tire. The position on the rim corresponding to the valve stem is generally the heaviest point on the circumference of the rim. By aligning the heaviest point on the rim with the lightest point on the tire, which is the position of the yellow dot or circle, they complement each other, helping to balance the weight distribution around the entire wheel circumference.

When temperature drops to the lower limit, the thermostat cuts power and the fan stops operating. Common electric fan failures: Besides blade damage, the most frequent issues include fan failure to rotate, excessive noise, and frequent cycling. Professional diagnosis at a service facility is required to determine the cause.

How to Open a Car Battery Cover?

Currently, most car batteries in use are maintenance-free types, which are sealed and cannot be opened. Here is more information about maintenance-free batteries: 1. Maintenance-free batteries are constructed with lead-calcium alloy grids and are designed with the latest technology from the 1990s, featuring a fully sealed structure and modern production processes. 2. These batteries produce minimal water decomposition and evaporation during charging, release less sulfuric acid gas, do not require any liquid replenishment, and have a longer storage time. Compared to traditional batteries, they offer superior performance, require no maintenance, are safe and reliable, and have a longer service life. 3. The lifespan of a maintenance-free battery is twice that of a conventional battery. It continuously converts electrical and chemical energy during charging and discharging to provide power for the car, making it a secondary battery.
