What Causes Sidewall Bulges in Car Tires?

[McAmy]

Tire bulging predominantly occurs due to unexpected strong impacts during use, which cause severe compression deformation between the impact object and the rim flange. This results in broken cords in the tire sidewall, allowing internal air pressure to push out at the break point, forming a "bulge." Hazards of Tire Bulges: Bulging is a common form of tire wear. If not addressed promptly, the accelerated rolling or excessive frictional heat can easily lead to sudden rupture at the bulged area, potentially causing a blowout. Statistics show that the majority of tire blowouts are caused by bulges. Tips to Prevent Bulges: When installing tires, visit a professional tire shop and use specialized equipment and procedures. Avoid prolonged driving on poor road conditions whenever possible. If unavoidable, maintain the slowest feasible speed, as lower speeds minimize the adverse effects of tire impacts with road obstacles. Develop a good tire maintenance routine by checking tire conditions before each trip.
