What Causes Bulges in Car Tires?
2 Answers
Here is the relevant introduction about car tire bulges:1. The bulged area of the tire has been impacted or squeezed: The most common scenario is when the car hits a curb at high speed or at an inappropriate angle. In such cases, there are usually impact marks, surface scratches, or white impact spots inside the bulged area of the tire. Careful inspection will reveal subtle differences.2. Tire quality issues: One possibility is that the fabric cords inside the tire have quality problems, leading to insufficient local strength; another possibility is poor handling of the cord layer joints. Bulges caused by quality issues show no marks on the surface or inside the tire at the bulged area.3. Insufficient structural strength in low-cost tires: The tire market is highly competitive. To reduce costs, low-cost tires may reduce the number of cord or nylon layers or use inferior cord layers, compromising the tire's strength. Even minor impacts can cause bulges.
I've seen many cases of tire bulging, mainly caused by accidentally hitting potholes or curbs while driving, which damages the internal structure of the tire. Aging is also a common factor – when tires get old, the rubber becomes brittle and loses elasticity, making them prone to bulging. Tire pressure is crucial too: excessive pressure makes tires too rigid, reducing their ability to absorb impacts; while insufficient pressure causes excessive deformation and friction-generated heat. Additionally, long-term overloading or manufacturing defects in tires can also lead to bulging. Safety first – a bulging tire is like a ticking time bomb that could blow out unexpectedly. It's recommended to check tire pressure monthly with a gauge and maintain it at the manufacturer's recommended level. When replacing tires, have a professional shop inspect the rims for deformation. Don't underestimate this maintenance – it can save significant repair costs and ensure safety.
