The underlying causes of tire deformation can vary. Common reasons include overinflation, underinflation, hitting potholes or curbs, and wear over time. Overinflation leads to harder tires that are more susceptible to damage from road hazards. Conversely, underinflation causes excessive flexing of the tire sidewalls, leading to overheating and premature wear. Physical impacts can also cause structural changes in the tire, leading to deformity.

Technical terms related to tire deformation include tread wear and sidewall bulges. Tread wear refers to the gradual loss of tire surface due to friction with the road. Sidewall bulges occur when the internal structure of the tire becomes compromised, often from impacts. Both conditions can severely impact performance by reducing grip and increasing the chances of tire failure.

The mechanisms involved in tire deformation include structural fatigue and heat build-up. As tires rotate at high speeds, the rubber generates heat. Excessive heat can weaken the tire structure, making it more prone to deformation. Additionally, continuous flexing of the tire during normal driving can lead to fatigue in the materials, causing them to lose their original shape over time.

Specific conditions that contribute to tire deformation include driving on uneven surfaces, improper tire maintenance, and exceeding load limits. For example, a vehicle loaded beyond its recommended weight can cause excessive pressure on tires, leading to deformation. Regularly checking tire pressure and alignment can help prevent issues. If you frequently drive in areas with poor road conditions, you may need to inspect your tires more often for signs of deformation.
