Is It Normal for Michelin Tires to Develop Cracks?
2 Answers
Michelin tires developing cracks due to normal wear is normal, and they are not prone to cracking within their lifespan. Here are some precautions for car tire maintenance: Pay attention to tire pressure: Pressure is crucial for tires, as both overinflation and underinflation can shorten their lifespan. Underinflation increases tire body deformation, leading to sidewall cracks and excessive flexing, which generates heat, accelerates rubber aging, and causes fatigue or breakage of the cord layers. Regularly check front wheel alignment: Front wheel alignment significantly impacts tire lifespan, with toe-in and camber being the main factors. Excessive camber accelerates shoulder wear and uneven wear, while improper toe-in mainly accelerates wear on the inner or outer edges of the tire. Be mindful of driving habits: Choose smooth roads when driving, avoiding sharp objects like stones, glass, and metal that could puncture or scratch the tires, as well as chemical spills that may adhere to and corrode the tires. When driving on roads with significant camber, try to stay centered to reduce uneven tire wear caused by increased load on one side.
I just replaced my Michelin tires less than two years ago and noticed some fine cracks on the sidewalls, so I consulted a seasoned tire shop technician. He explained that minor surface cracking is indeed a normal aging phenomenon, especially common in northern regions with significant temperature variations. However, it's crucial to check the depth of the cracks—if the tread feels brittle to the touch, it's a warning sign that the rubber's molecular structure is starting to degrade. My tires were deemed still usable after inspection, but the technician advised applying tire wax during each car wash to maintain them and avoid prolonged sun exposure that could accelerate cracking. He also emphasized paying special attention to the tire's age: even without visible cracks, tires older than five years should be considered for replacement, as safety comes first. Now, I've developed a habit of checking my tire condition monthly, and addressing any abnormalities promptly gives me much greater peace of mind.
