When tire wear reaches 1.6mm, replacement is mandatory. Factors related to wear level: Tire tread wear level - new tires typically have a thickness of around 8mm. When wear reduces this to approximately 1.6mm, the tire should be replaced. The rate of wear is directly influenced by mileage and driving habits. The normal lifespan ranges between 50,000 to 80,000 kilometers. Upon reaching this mileage, regular checks of tire thickness should be considered. Tread aging degree: Tire aging significantly depends on usage duration and environmental conditions, with a standard service life of about 6 years. Harsh environments can accelerate this timeline. Aged tires will exhibit numerous surface cracks. If such signs are observed, immediate replacement is advised even before reaching 6 years, as delayed action may lead to severe blowout risks.

What Causes the Sunroof to Make Noise?

Reasons for sunroof noise: 1. Aging of sunroof rubber seals or gaskets. Sunroof seals exposed to prolonged rain or sunlight can easily deteriorate. Rubber conditioner can temporarily restore seal performance. The solution is to replace the sunroof seal or apply conditioner to the seal. 2. Loose sunroof screws. Loose screws can cause roof noise and sunroof noise, and may even pose a risk of the sunroof detaching. The solution is to locate and tighten the sunroof screws. 3. Dust particles in the sunroof tracks. Repeated opening and closing of the sunroof inevitably leads to dust accumulation in the track gaps. When enough dust accumulates, friction occurs during sunroof operation, causing noise. The solution is to wipe away the dust with a cloth.
