Where to Repair Alloy Wheels?

Both auto repair shops and 4S stores can perform the repairs. Below are the details: 1. No damage to the wheel surface: If there are only some scratches, the refurbishment is relatively simple, requiring only surface repair and repainting. 2. The wheel is deformed: But not broken or cracked. Although this situation is more complex, it can still be handled. The wheel can be heated, restored to its original shape, balanced, and then repainted for continued use. Below is some related information about tires: 1. Tire lifespan: The wear lifespan of tires is between 30,000 to 50,000 kilometers. If the tire hasn't reached the wear limit or mileage but has been in use for 5 years or has developed numerous cracks on the side, it should be replaced. 2. Tire material: The main component of tires is rubber. The maximum storage and anti-aging time for rubber, from natural latex to ethylene propylene and nitrile, does not exceed 10 years. The average service life of various rubber products in use is 3-5 years.

What Does Tire Calibration Mean?

Tire pressure calibration refers to the situation where the vehicle's wheels have low tire pressure or other tire pressure issues. During driving, the system automatically monitors the tire pressure in real-time and alerts the driver in case of air leakage or low pressure to ensure driving safety. Over time, tire pressure decreases and needs to be refilled to the standard value, after which the tire pressure can be reset via the vehicle's multimedia system. Below are additional details: 1. Excessive wear on both sides of the tire: This is caused by prolonged low tire pressure or frequent overloading. Overloading or low tire pressure increases the contact area between the tire and the ground, leading to abnormal wear on both sides. 2. Central wear of the tire: This occurs due to high tire pressure. Excessive tire pressure causes severe tire deformation, reducing the contact area to the tread part, resulting in excessive central wear. Additionally, high tire pressure can affect the vehicle's comfort. 3. Wavy wear on the left and right tire shoulders: The main cause is a significant difference in the wheelbase between the front and rear wheels, where the right side is larger than the left, exceeding the standard.

What do 91V and 91W mean on tires?

The difference between 91V and 91W tires lies in the letters V and W at the end. These letters represent the speed rating of the tire. V indicates that the tire can withstand a maximum speed of 240 km/h, while W means the tire can handle up to 270 km/h. In other words, a 91W tire can bear a load of 615 kg and support a maximum speed of 270 km/h. Here is some related information about tires: 1. Tire lifespan: The wear life of a tire is typically 30,000 to 50,000 kilometers. If the tire hasn't reached the wear limit or mileage but has been in use for 5 years or shows significant sidewall cracking, it should be replaced. 2. Tire material: The main component of a tire is rubber. The maximum storage and anti-aging period for rubber, from natural latex to EPDM and nitrile, does not exceed 10 years. The average service life of various rubber products in use is 3-5 years.

What are the hazards of aluminum alloy valve caps?

One major hazard of aluminum alloy valve caps is that aluminum is chemically unstable and prone to react with oxygen. During the oxidation process, the valve core can become stuck together, making it difficult to unscrew after prolonged use. Additionally, the tire valve stem is connected to the tire pressure monitoring sensor. If excessive force is applied when trying to unscrew it, the stem may break, requiring replacement of the entire set. However, without unscrewing the cap, inflating the tire becomes impossible. Below is more detailed information: 1. When the aluminum valve cap becomes rusted and stuck: It can be very hard to remove. You can try spraying some penetrating oil or wrapping a towel around it and using pliers to twist it off. If these methods fail, you may have to resort to more forceful measures or seek assistance from a repair shop. 2. To prevent aluminum valve caps from rusting and sticking: Rubber valve caps can be used as an alternative, but they also have drawbacks. Over time, rubber inevitably ages, and the part in contact with the wheel rim may gradually crack, deform, and lose elasticity. Therefore, under normal circumstances, valve stems should be replaced every 3-4 years, which is roughly the same lifespan as the tires. It is recommended to replace the valve stems when changing tires.

What Causes the Sudden Illumination of the CRV Airbag Warning Light?

Introduction to the reasons for the sudden illumination of the CRV airbag warning light: 1. Loose or poor contact in the airbag device wiring: There are airbag device wires under the car seat, which may become loose due to accidental kicking by rear seat passengers. Simply check and tighten the connectors. 2. Faulty sensor in the airbag device: This requires inspection and repair at a professional auto repair shop or 4S store. 3. Battery depletion or abnormal reception device code: This requires professional testing of battery voltage or using a diagnostic device to check the code to troubleshoot.

What is a motorcycle with a sidecar called?

A motorcycle with a sidecar is called a sidecar motorcycle. Additional information: Motorcycles with sidecars generally have special purposes and are mainly equipped by various departments. However, with the popularity of cars, most sidecar motorcycles have been replaced by various vehicles. Still, a small number remain in use, such as the Jialing 600 sidecar three-wheeler, which is equipped by the military, though it is rarely seen on the road. Related information: The advantage of a sidecar motorcycle is that it can carry three people simultaneously, and the passenger in the sidecar enjoys comfortable riding conditions. Structurally, sidecar motorcycles can be divided into two types: integral sidecar motorcycles and detachable sidecar motorcycles. They are modeled after the BMW three-wheeled motorcycles from World War II.
