What to Do If the Edge of the Tire Is Slightly Scratched Off?

If the tread is slightly scratched off and not very deep, it can continue to be used normally. However, if the steel wire is exposed, it needs to be repaired or replaced with a new tire. Below is relevant information about tires: 1. Wear: Tires have wear indicators. There are triangle marks on the side of the tire. When the wear reaches the point indicated by the triangle mark, it is recommended to replace the tire. There are also raised marks inside the tire's drainage grooves. When the wear reaches the level of these raised marks on the tire surface, the tire should be replaced. Simple punctures can be repaired without needing replacement. Bulges must be replaced. 2. Aging: Rubber oxidizes in the air, and oxidized rubber hardens, reducing grip. Therefore, even if a set of tires is left unused, its lifespan will decrease. It is not recommended to use tires for more than 5 years from the production date. The production date is marked on the side of the tire.

What does the fit designation h7r6 represent?

h7/r6 is an interference fit. In the mechanical industry, any fit marked with H7/r6 refers to a fit under the condition of the same nominal size, and H7/r6 is always an interference fit. Definition of transition fit: Transition fit refers to a fit that may result in either interference or clearance. Therefore, regardless of the actual dimensions, as long as the h7/r6 fit is selected, whether the tolerance zones overlap or not, it is considered a transition fit. Relevant regulations: When the hole is taken as the reference, H7 is the reference hole with a tolerance grade of 7, and h6 is the shaft with a clearance fit of grade 6 accuracy. When the shaft is taken as the reference, h6 is the reference shaft with a tolerance grade of 6, and H7 is the hole with a clearance fit of grade 7 accuracy.

How many points will be deducted for reversing on the ramp?

Reversing on a highway ramp will result in a 12-point deduction. Reversing on a highway ramp not only endangers your own life but also the lives of others. Relevant regulations: A highway ramp is the road on the right side of a highway exit or entrance, meaning it is part of the highway. According to relevant regulations, U-turns, reversing, and parking are not allowed on highways, so you cannot make a U-turn, reverse, or park on a highway ramp. What to do if you mistakenly enter a ramp: If you mistakenly enter a ramp because you didn’t see the warning signs, you should continue driving to the exit and then replan your route. Do not reverse or drive in the opposite direction. Ensure traffic safety by immediately pulling over to the emergency lane, turning on the hazard lights, and moving to a safe area outside the guardrail. Then, place a warning triangle 100 meters in front of the vehicle and contact the traffic police. Cooperate fully with the police when they arrive at the scene.

Will Car Windshield Washer Fluid Freeze in Winter and What Are Its Functions?

Whether car windshield washer fluid freezes in winter depends on two scenarios: 1. Antifreeze washer fluid will not freeze. Antifreeze washer fluid ensures it remains unfrozen even when the external temperature drops below -20°C. It is an all-weather windshield cleaning solution containing antifreeze and cleaning components, capable of preventing freezing in winter and directly dissolving frost. 2. Ordinary washer fluid may freeze in winter. Windshield washer fluid primarily serves the following three functions: (1) Cleaning performance: Windshield cleaner is formulated with various surfactants and additives. Surfactants typically have wetting, penetrating, and solubilizing properties, thereby achieving cleaning and stain removal effects. (2) Antifreeze performance: The presence of alcohol and ethylene glycol significantly lowers the freezing point of the liquid, providing antifreeze protection and quickly dissolving frost. (3) Anti-fog performance: A single-molecule protective layer forms on the glass surface. This protective film prevents the formation of fog droplets, ensuring the windshield remains clear and transparent with unobstructed visibility.

How to Maintain Tires?

Tire maintenance involves the following four methods. 1. Perform wheel alignment and tire rotation: Conduct wheel alignment and tire rotation every 10,000 kilometers. 2. Regularly check tire pressure: Tire maintenance also includes periodic pressure checks. Tires exceeding the specified pressure will significantly reduce their lifespan, while tires below the specified pressure can lead to poor braking performance, difficulty or heaviness in steering, and also shorten tire life. 3. Always pay attention to the wear indicators on tires: The tire wear indicator is located in the main drainage grooves of the tire and is a trapezoidal rubber protrusion. When the tread wears down to the level of the wear indicator, the tire must be replaced. During the rainy season, to prevent the vehicle from slipping on wet roads, the tread depth must be maintained above 3mm. 4. Regularly inspect tire condition: Frequently check tires to promptly identify issues such as bulges, cracks, cuts, punctures, valve rubber aging, and abnormal tire wear. Pay special attention to inspecting the wear on the tire tread and edges.
