Can Tires with Cracks on the Sidewall Still Be Used?

Tires with minor cracks on the sidewall can still be used normally, but if the cracks are numerous and deep, they should be replaced. Generally, car tires can last for about three years, but for frequent drivers, it's advisable to replace them every two years. Below is relevant information: Tire Lifespan: The typical lifespan of a tire is around 3 years or 50,000 kilometers. Beyond this period, tires begin to age. The main signs of aging include surface hardening and the appearance of cracks. Aged tires lose their elasticity, and continued use can lead to tread deformation, increasing the risk of a blowout. Tire Cracking: If the cracking is localized and doesn't compromise safety, the tires can still be used for high-speed driving. However, extensive cracking is a sign that the tires should be replaced immediately. Cracks on the front tires can affect water drainage and reduce surface friction, leading to longer braking distances and decreased stability during high-speed turns.

I'm quite concerned about cracks on the tire sidewall because from a safety perspective, it absolutely shouldn't be used anymore. The sidewall is the weakest part of the entire tire, and once cracks appear, it may suddenly blow out during high-speed driving, with unimaginable consequences. Cracks are usually signs of tire aging, such as dry rubber cracking or hardening due to UV exposure, or caused by excessive pressure on the sidewall when parked. Minor cracks aren't a big issue yet, but deep cracks can be felt by touch, indicating risk—I believe anything over 2mm warrants immediate replacement. Before daily driving, I always spend a minute checking tire conditions to prevent small issues from escalating. Additionally, cracks can affect tire pressure stability, increasing fuel consumption and noise. Safety is fundamental—don't risk your life to save a few hundred bucks. Get it checked at a professional shop ASAP to ensure safety for yourself and others.

I understand tire structure and can analyze sidewall cracking from a technical perspective: The rubber layer on the tire sidewall is thin, and cracks indicate material aging or damage, possibly due to prolonged exposure to sun and wind making the rubber brittle, or insufficient tire pressure causing excessive compression. For minor surface cracks, observe their depth - if they don't create significant ridges when scratched with a fingernail, short-distance use may still be possible. However, deep cracks or extensive cracking patterns are highly dangerous with increased risk of blowout. Generally, tires have a lifespan of 5-6 years, and visible cracks likely indicate they're past their service life. I recommend first checking if tire pressure is normal (maintain 22-32 psi), then inspecting crack locations to prevent worsening sidewall damage. If uncertain, consult a professional to test structural integrity with proper tools. These technical details aren't meant to scare, but to ensure safe driving.

With over 20 years of driving experience, I can personally attest that cracks should never be taken lightly: Once before a business trip, I noticed a small sidewall crack but was too lazy to replace the tire. On the highway, the tire suddenly started trembling and nearly caused a loss of control, giving me a real scare. I've learned my lesson now – sidewall cracks usually indicate tire aging or rubber drying from prolonged parking. Even minor cracks signal structural weakness, meaning the tire could potentially split open on bumpy roads. Experience has taught me not to take chances; when I spot a crack, I stop using the tire immediately and check its depth. Slight cracks might be manageable for short, slow drives, but the risk remains high. I now maintain my tires regularly to avoid such hazards, because after all, cars are life assistants where safety comes first.
