Can You Still Drive with a Bulging Tire?

[Dawson]

You cannot drive with a bulging car tire because prolonged or high-speed driving can cause the tire temperature to rise, which may easily lead to sudden rupture of the bulging area, resulting in a tire blowout. A tire bulge occurs because the inner layer of the tire consists of a fabric ply without steel wires—only nylon cords that prevent the internal gas from bulging outward. When several cords break simultaneously, the damaged area is left with only elastic rubber to support it. Under the pressure of the gas, the rubber expands, forming a bulge. Prolonged or high-speed driving raises the tire temperature, increasing the risk of sudden rupture at the bulging spot, i.e., a blowout. To prevent tire bulges and blowouts, follow these precautions: 1. Drive slowly on poor road conditions: If you drive a regular passenger car, avoid rough roads or drive cautiously in such areas. 2. Avoid uneven force distribution: When parking, do not partially mount curbs or uneven surfaces, as this can cause uneven tire stress. 3. Prevent rim damage: Slow down when crossing speed bumps to avoid rim scratches and tire impact, which may contribute to bulging over time. 4. Regularly check tire pressure: Ensure the tire pressure remains within the normal range to prevent bulging caused by abnormal pressure.
