Many car owners say that is tire manufacturer quality problem whenever they encounter a tire bulge problem, that is, they do not admit that they are caused by bad driving habits.

  Truth: tire manufacturer has proved that 90% of tire bulging is caused by side impact of tire through a large number of experimental data. The unexpected strong impact of tire in use, such as bumping into road teeth, passing through pits at high speed, passing through sunken well caps, pressing to raised well caps, etc., results in serious extrusion deformation between impact objects and rim flanges, resulting in yarn breakage of tire wall curtain cloth. At this time, the air inside the tire will rise from the broken yarn and form a drum. Not all of the problems are tire manufacturer problems, but also due to bad driving.
