What Are the Basic Knowledge Points About Tires?

Tire basics are as follows: Tire Size: The tire size is printed on the sidewall and is represented in two ways: High-pressure tires are generally denoted by "tire diameter × tire section width," such as 34×7; low-pressure tires are usually represented by "section width ~ rim diameter," such as 7.5~20, with the unit in inches (1in=0.0254m). Replacement Standard: According to technical standards, tires should be replaced when the tread grooves are less than 1.6mm. If the wear indicators on the tread grooves are exposed, it indicates that the groove depth is insufficient at 1.6mm. The tire wear indicators are the raised sections within the tread grooves. Using tires with remaining tread depth below 1.6mm may result in sudden loss of traction and braking force in rainy conditions, as well as a complete lack of traction in snowy conditions.

What is the standard size of a compact car?

There is no standard size for compact cars, as the body dimensions vary depending on the vehicle class. Even within the same class, body sizes can differ significantly. Generally, higher-class vehicles have larger dimensions, higher displacement, and better configurations. Currently, passenger cars are classified into six levels: A00, A0, A, B, C, and D. Typically, the length of an average family compact car ranges between 3800mm and 4300mm, the width between 1600mm and 1800mm, and the height between 1400mm and 1600mm.

Does a Rear-End Collision Count as an Accident Vehicle?

Only the bumper is damaged: Clearly, this is just a minor traffic accident where only the bumper and sheet metal parts are affected, so it does not qualify as an accident vehicle. It's worth mentioning that even if the rear bumper is replaced, it still does not count as an accident vehicle, and the same applies to the front bumper. Slight deformation of the rear panel: If the rear panel is deformed due to impact, the rear bumper is certainly ruined. If the deformation of the rear panel can be repaired through hammering and frame traction, it does not qualify as an accident vehicle. However, if the rear panel requires cutting, welding, or replacement, then it can be classified as an accident vehicle. Rear deformation affecting the suspension: Without a doubt, if a rear-end collision impacts the suspension, it must be a very severe impact. Components such as the rear bumper, rear panel, spare tire well, and trunk lid are likely to be deformed, so it definitely qualifies as an accident vehicle.

What Causes the Squeaking Sound When Opening the Car Door?

The reasons for the squeaking sound when opening the car door are: 1. The door hinge may have rusted or deformed due to prolonged use. After cleaning the surface dirt from the door hinge, limit arm, limit pin shaft, and connecting bracket, you can apply specialized lubricating oil appropriately; 2. It could be due to loosening or deformation of the internal window regulator causing the noise; 3. It might also be caused by the door trim panel not being securely fixed or the fastening clips falling off. The door and the car body are connected via hinges, and it is normal for hinges to produce noise after prolonged use. To ensure the pulley remains smooth and quiet for a long time, you can apply lubricating oil every 2 to 3 months for maintenance. Additionally, some cars with relatively ordinary assembly processes may have door limiters that are prone to deformation, leading to squeaking sounds, which can only be repaired or replaced at a service center.

Will Adhesive Remover Damage Car Paint?

Improper use of adhesive remover can damage car paint. If sprayed for a short duration, it won't harm the paint, but prolonged exposure can soften the paint, making it easy to peel off with a fingernail. It is recommended not to exceed one minute of exposure; around 30 seconds is sufficient. Adhesive remover can remove organic adhesives, glass glue, double-sided tape, sticky labels, blister glue, soft glue, acrylic resin glue, epoxy resin glue, and polyurethane glue. Precautions for using adhesive remover: 1. The product is volatile and should be stored in a plastic container with the lid tightly closed during soaking; 2. The product is flammable, so keep it away from fire sources; 3. The product is corrosive, so wear protective gear when handling it. If it accidentally comes into contact with the skin, rinse immediately with water.

Can a patched tire be patched again?

Generally, it is possible, but it requires grinding the damaged area again before applying a new patch. However, repeatedly patching the same spot can compromise the tire's safety. Additionally, if the damage is on the sidewall—the weakest part of the tire—it doesn't necessarily need repair if the cords aren't exposed. However, it's advisable to move this tire to the rear and use it only for city driving. Below are the common repair methods: 1. Traditional Plug Method: This involves using a tool like an awl to enlarge the puncture hole, then inserting a rubber strip coated with adhesive into the hole. It's quick, inexpensive, and doesn't require separating the tire from the rim or performing wheel balancing. However, enlarging the hole can increase the damaged area, raising the risk of air leaks. 2. Patch Repair Method: This method involves separating the tire from the rim, grinding the inner surface of the damaged area to improve adhesive bonding, cleaning the debris, applying a special tire repair adhesive, and firmly pressing a patch over the damaged area. An additional layer of adhesive is then applied to complete the repair. 3. Mushroom Plug Repair: This method also requires separating the tire from the rim and performing wheel balancing afterward. The key difference from the patch method is that the mushroom plug effectively fills the puncture hole's gaps, preventing further damage. This approach is more secure, thorough, and stable compared to other repair methods.
