How deep is the sidewall scratch allowed for BMW tires?

BMW tires allow sidewall scratches up to 4mm. Scratches exceeding 4mm require replacement. Sidewall scratches increase the risk of tire blowouts: When the tire sidewall is damaged, there's a high probability of damaging the radial ply. Once the radial ply is compromised, the entire tire structure loses protection and the tire may burst at any time. When parking, be careful not to get too close to the curb as this can cause uneven friction on the sidewall. Over time, this may lead to bulges or scratches, increasing the risk of tire blowouts. Sidewall scratches affect safety: If the tire sidewall is cut, especially when damaging the cord ply, it completely breaks the structural stress of the sidewall, significantly increasing the risk of safety accidents.

Can tires stored for seven or eight years still be used?

Tires stored for seven or eight years are not recommended for use. Tires are rubber products and will naturally age even if not used. Continuing to use them poses a risk of blowouts. Here is some information about car tires: 1. Tire lifespan: Generally, tires last 6-8 years, with a maximum of up to 10 years. For tires older than 6 years, check the edges for rubber cracks. If no significant cracks are found, they can still be used. However, if numerous cracks are observed, it is advisable to replace the tires. 2. Tire mileage: If the tires have no issues (such as excessive patching, side punctures, etc.), but have been in service for four years, they should be replaced even if the mileage has not reached 80,000 kilometers. Similarly, if the mileage reaches 80,000 kilometers before four years, replacement is also recommended.

What Causes the Abnormal Noise in the Geely Boyue's Steering Gear?

Abnormal noise in the Geely Boyue's steering gear may be caused by component friction, clock spring failure, or steering gear malfunction. Component Friction with the Steering Wheel: Excessive rotational clearance between various plastic components and the steering wheel can lead to abnormal noise, especially in new cars, which require adjustment and break-in. Clock Spring Failure: Inside the steering wheel, abnormal noise may occur due to a broken clock spring or a loose clock spring connector. Replacing the clock spring can resolve this issue. Dust Boot Oil Leak: When the steering gear's dust boot leaks oil, abnormal noise may occur during rotation. In this case, replacing the dust boot or adding lubricant can solve the problem.

What Causes the Abnormal Noise When Shifting to P Gear?

There are two scenarios when abnormal noise occurs while shifting to P gear. First, if you park on a slope and shift to P gear before engaging the handbrake, a 'clunk' sound is considered normal. Second, if you shift gears before the car comes to a complete stop, a 'clunk' sound can occur, which significantly shortens the transmission's lifespan. The reasons for abnormal noise when shifting to P gear are as follows: 1. Broken or fractured gears; 2. Malfunction in the transmission's internal mechanism; 3. Damaged internal bearings. Precautions for gear shifting include: Do not look down while shifting gears to ensure driving safety; Hold the steering wheel steady with one hand while shifting gears with the other; Avoid violently shaking the gear lever back and forth; Ensure the gear matches the vehicle's speed.
