Tire H represents the speed rating of the tire. Each tire has its speed symbol (also known as speed rating) molded on the sidewall. By referring to the speed symbol, you can determine the maximum speed capability of the tire. For example, in the tire specification 195/65R15 91H, the speed symbol is H. Checking the speed symbol and speed correspondence table reveals that this tire has a maximum speed of 210 kilometers per hour. Automotive tires are one of the crucial components of a vehicle, directly contacting the road surface and working together with the vehicle's suspension to absorb shocks during driving, ensuring good ride comfort and smooth operation. They also maintain excellent traction between the wheels and the road surface, enhancing the vehicle's traction, braking, and off-road performance. Tire tread patterns can be categorized into rib patterns, transverse patterns, mixed patterns, and off-road patterns.

What Causes a Motorcycle to Lose Power When It Gets Hot?

Motorcycles losing power when hot can be attributed to the following reasons: 1. Overly rich air-fuel mixture: If the issue only occurs when the engine is hot but functions normally when cold, it is generally caused by an excessively rich mixture due to various factors. Even after replacing the carburetor with a new, quality-assured unit and ensuring correct adjustment of the mixture ratio, choke, and needle valve, you should also inspect whether the air filter is clogged, as this can also lead to a rich mixture. 2. Ignition system failure: Check for issues with the high-voltage electricity. Some motorcycles may experience ignition component failures when hot, such as malfunctioning igniters, faulty ignition coils, or damaged stator coils in the magneto, resulting in misfires when the engine heats up while showing no obvious abnormalities when cold. If the spark plug, air filter, and carburetor are confirmed to be functioning properly, further inspection of the ignition system components is recommended.

Can Electric Vehicles Be Charged in the Rain?

Electric vehicles can be charged using charging piles during light rain, but it is advisable to avoid charging operations during heavy rainfall. Here are the specific details: Waterproofing capability of charging piles: During the construction of charging piles, waterproof materials are applied to the bottom of the charging facilities. This ensures that the lower 20-30 cm of the charging pile body has the ability to withstand water immersion. National standards for the waterproof performance of charging piles are very stringent. Before charging begins, both the vehicle side and the pile side undergo insulation testing. If the insulation test fails (due to rainwater or debris), charging cannot be initiated. Therefore, charging piles generally have no issues with exposure to rain. Waterproofing of charging interfaces: Even though charging piles are equipped with waterproof materials, it is generally recommended not to charge during rain. Some consumers worry that the charging interface might short-circuit due to rain. Even if manufacturers use insulating materials at the charging pile interface, charging during rain can still pose risks.

What are the penalties for running a right-turn red light?

Since the enactment of the new traffic law in 2016, traffic regulations have become very strict. The new regulations stipulate that running a red light, which was previously penalized with a 200 yuan fine and 3 demerit points, was changed to a 200 yuan fine and 6 demerit points starting from January 1, 2016. In many places, being caught by electronic surveillance only results in a 200 yuan fine without deducting points. Although running a yellow light is not penalized, it is still advisable to avoid doing so. In the absence of specific traffic instructions, motor vehicles can make a right turn at a red light without it being considered a violation. However, at intersections with 'No Right Turn' traffic signs, vehicles must stop when the light is red. Making a right turn in such cases is equivalent to running a red light, which incurs a penalty of 6 demerit points and a fine ranging from 100 to 200 yuan for violating traffic signal rules.
