Can tires with cracks on the sidewall still be used?

They can be used, but regular inspections of the tire condition are necessary. If there are numerous and deep cracks, immediate replacement is required. Below is relevant information about tires: Tire Introduction: Tires are the only components of a car that come into contact with the ground. Some car owners only replace the tires on the drive wheels when changing tires. For example, some front-wheel-drive car owners only replace the two front tires, while some rear-wheel-drive car owners only replace the two rear tires. In fact, this practice is acceptable. Tire Aging: Tires are rubber products and will age over time. It is recommended that car owners replace their tires every four years, even if the mileage within those four years is relatively low. This is because tires can also age when left unused for extended periods, so it's important to check the production date when purchasing new tires.

I found cracks on the sidewall of the tire, which means it absolutely cannot be used anymore—this is quite dangerous. The tire sidewall is a critical load-bearing part of the vehicle, and cracks usually indicate rubber aging, excessive sun exposure, or prolonged use, potentially leading to sudden blowouts at high speeds and significantly increasing the risk of accidents. I’ve seen many car owners continue using them to save money, only for a small oversight to lead to major trouble. Safety comes first—don’t take chances. It’s advisable to inspect tires regularly, gently scratching the cracks with a fingernail to gauge their depth. If they’re noticeable, replace the tire immediately, opting for reputable brands for reliability. After all, driving safety affects both you and others, and timely action can also prevent unexpected repair costs from escalating.

My neighbor recently had this issue. He kept driving with a cracked tire and nearly got into an accident on the highway. Later, he regretted not replacing it sooner. I believe sidewall cracks in tires should never be ignored. Cracks are usually caused by rubber oxidation, aging, or curb impacts. Continuing to use them increases the risk of a blowout under pressure. My advice is to stop using the tire immediately if you spot any cracks, even tiny ones, and replace it for safety. Replacing a regular tire isn’t difficult—just visit a reputable shop and spend a few hundred bucks. It’s far cheaper than dealing with potential accident costs. Regular tire maintenance, like checking pressure and wear, can prevent such problems. Don’t let small issues turn into big disasters.

From an economic perspective, it's more appropriate to stop using tires with cracks on the sidewalls. Replacing new tires may cost around 800 to over 1,000 yuan, but continuing to use cracked tires could lead to blowouts, resulting in repair, towing, or even medical expenses that may amount to tens of thousands—definitely not worth it. Tires typically have a lifespan of five to six years, and cracks are a sign of aging. Ignoring them is gambling with high costs. I recommend not skimping on this investment in safety and promptly visiting a professional shop to check if replacement is needed. In daily use, avoiding parking in direct sunlight can delay the appearance of cracks. These small considerations save money and hassle in the long run while reducing risks.

My experience is that tire maintenance should never be taken lightly. Sidewall cracks are mostly caused by rubber deterioration, such as oxidation or UV damage, leading to reduced strength, and continued use poses significant risks. It's advisable to park in shaded areas and rotate tires regularly to slow down aging. Any visible cracks indicate it's time for replacement—don't risk driving on them. Routine checks on tire pressure and surface condition can help detect issues early. If similar signs are spotted, have a repair shop evaluate them and replace the tires promptly to ensure driving safety. Preventing minor issues avoids major accidents.

Don't panic if you notice sidewall cracks while driving, but handle it calmly. Slow down and pull over to check the crack size: minor cracks allow slow driving to a repair shop, while deep cracks or bulges require stopping and calling a tow truck for tire replacement. Cracks stem from aging and pressure issues—don't push it. When replacing tires, choose the right specifications and brands for long-term safety. I recommend keeping emergency tools and contact info in the car to prevent unexpected trip interruptions. Regular maintenance checks on tire condition cultivate cautious habits that avoid roadside crises and ensure smooth journeys.
