What Causes Cracks in Tires of a New Car Less Than a Year Old?
2 Answers
Cracks appearing in the tires of a new car less than a year old may be related to the quality of the tires. Below is an introduction to tire-related information: 1. Functions of tires: Mainly include dry grip, hydroplaning resistance, providing comfort, reducing driving noise, impact resistance, wet grip, load-bearing capacity, handling performance, average wear, and mileage. 2. Tire cross-sectional structure: Generally, it can be divided into four parts: tread, shoulder, sidewall, and bead. Each part has its own function. The tread mainly contacts the ground, the shoulder and sidewall provide support, and the bead contacts the rim to provide sealing. 3. Internal composition of tires: The inside of the tire is composed of multiple layers of different materials, including tread pattern, cover layer, steel belt layer, stress absorption rubber strip, carcass ply layer, and airtight layer.
My car's tires developed cracks within less than a year, something I encountered right after buying the car last year. It makes me uneasy while driving. Maybe it's because I drive too aggressively, frequently braking and accelerating sharply in the city, which causes significant tire wear and makes the rubber prone to cracking. Another common reason is the parking environment—I rent a place without a garage, so my car is often parked outdoors, exposed to the scorching sun for hours in summer, and high temperatures accelerate rubber aging. Check if it's a quality issue; some new cars come with defective tires from the factory, and you can claim free warranty service from the manufacturer. Also, check the tire pressure—both overinflation and underinflation can cause cracks. Since I bought a tire pressure monitor, I've had fewer issues. Make it a habit to check your tire condition monthly and avoid driving too fast on rough roads.
