Tyre bulge is the most important factor causing a puncture.
Why are tires bulging?
Tyre bulges are caused by broken cords. The side of the tire is supported by nylon threads one by one. If several wires are broken at the same time, only the rubber is left to support this place, and the tire will soon be bulging.
Causes of cord breakage
Cord breaks are caused by external forces on the tires.
Common situations are:
The side of the tire is squeezed, for example, the road teeth will be squeezed to the side;
Over speed bumps or large potholes and deep grooves without deceleration, tires are hit hard, and the sidewalls are stressed too much;
The tire pressure is too low, the deformation of the side of the tire is too large, and the tire is repeatedly bent, causing fatigue and fracture of the cord.
Whether it is a bulge or a damaged side, it cannot be repaired and cannot be repaired.
Because the ply has been broken in this area, the tire repair only puts a rubber sheet inside, and there is no way to repair the ply.
Therefore, after driving for a period of time, there will be a bulge in the place where the tire is repaired, and there may even be a risk of a tire blowout, which is a huge safety hazard.
In addition, the side of the tire is always in a state of deforming and then recovering when driving, and it is easy to fall off when repairing the tire. Check the car and don’t forget to check the side of the tires. As long as the tire is found to be bulging, it can no longer be used, and it must be replaced in time. If the bulge is very small, you can also drive to the tire shop at low speed to change the tires. Avoid long-distance high-speed use.
