Is a Bulging Car Tire Covered Under Warranty?
2 Answers
If a car tire bulges during the warranty period due to manufacturing defects, compensation or replacement will be provided according to the Three Guarantees Law. However, if the bulging is caused by the owner's negligence or improper use, it will not be covered. Tire Maintenance Methods: Perform Wheel Alignment and Tire Rotation: Conduct wheel alignment and tire rotation every 10,000 kilometers. Regularly Check Tire Pressure: Tire maintenance also includes regular pressure checks. Overinflated tires significantly reduce tire lifespan, while underinflated tires can lead to poor braking performance, steering difficulties, or heavy steering, and also shorten tire life. Always Pay Attention to Tire Wear Indicators: Tire wear indicators are located in the main tread grooves and appear as trapezoidal rubber blocks. When the tread wears down to the level of these indicators, the tire must be replaced. During the rainy season, to prevent skidding on wet roads, tread depth should be maintained at least 3mm. Regularly Inspect Tire Condition: Frequently check tires for bulges, cracks, cuts, punctures, valve rubber aging, and abnormal wear. Pay special attention to tread and sidewall wear.
I've been driving for ten years and have seen plenty of tire bulges—they're rarely covered by warranty. Most manufacturers classify tire bulges as damage caused by improper use, like hitting a pothole, curb, or sharp object while driving, which damages the internal cords. This isn't considered a manufacturing defect, so you usually have to pay out of pocket for a replacement. I remember once when my own car had a bulging tire, the dealership inspected it and said it was due to external force. The warranty explicitly stated it only covered material and workmanship issues. The safety risk is serious—bulges can easily lead to blowouts, especially at high speeds. If a newly purchased tire bulges soon after installation, you might try filing a complaint with the seller, providing evidence that it's a quality issue rather than road conditions. For prevention, developing the habit of slowing down over rough terrain can save you trouble. If it happens, get it replaced at a professional shop as soon as possible—don't cut corners to save money.
