Can tires with small cracks on the sidewall still be used?
3 Answers
If the cracks on the sidewall are relatively small, they can still be used on city roads for the time being without immediate replacement, but they should not be used for high-speed driving. If the small cracks on the sidewall have damaged the internal structure of the tire, it cannot be used further and needs to be replaced promptly. If the sidewall is only scratched by gravel or sharp objects, such shallow cracks will not affect driving, but it is important to note that such scratches will shorten the tire's lifespan and should not be used for too long. Car tires are one of the essential components of a vehicle, as they directly contact the road surface and work together with the car's suspension to absorb shocks during driving, ensuring a comfortable ride and smooth operation. They also ensure good adhesion between the wheels and the road surface, improving the vehicle's traction, braking, and off-road capabilities.
Ah, I remember one time when my tire sidewall had small cracks. At first, I thought it was just superficial marks and no big deal. But then, during a long highway trip, the tire suddenly blew out, nearly causing a major accident. Later, I learned that tire rubber aging was the main culprit—prolonged exposure to sunlight made the material brittle and prone to cracking. Small cracks may seem harmless, but the internal structure could be compromised and gradually worsen. Under the high pressure of highway speeds, they can tear completely and fail. Since then, I’ve made it a habit to check my tire sidewalls every week, inspecting them closely or gently pressing to test the depth of any cracks. I advise all car owners to take photos of any cracks they find and compare them over time. If the cracks multiply or deepen, don’t delay—replace the tire. Safety should always come first. Spending money on new tires is far better than dealing with car repairs or personal injuries. Generally, tires last about five years, and beyond that, the risks increase significantly.
As an automotive enthusiast with years of experience, minor cracks on tire sidewalls are mostly caused by rubber oxidation or aging. Factors like prolonged parking under sunlight or driving with low tire pressure accelerating wear can lead to these marks. If the cracks are shallow, they might still hold up for a while, but depth inspection is crucial; gently scratch with a fingernail – if the inner cord layers are exposed, replace immediately as reduced support increases high-speed blowout risks. For daily driving, maintain standard pressure with regular inflation and visually inspect sidewalls monthly. Few cracks may allow cautious city driving at low speeds, but highway use significantly raises danger. Tire structure is sensitive with weak sidewall areas posing major hazards – don't cut corners here. New tires aren't expensive, and maintaining driving stability is non-negotiable.
