Can a car tire with cracks continue to be used?

Car tires with cracks should not continue to be used. The maintenance methods for tires are: 1. Regularly clean the stones in the tire treads; 2. Reduce exposure to sunlight; 3. Promptly check the tire pressure; 4. Pay attention to the maintenance of the suspension; 5. Regularly inspect the front wheel alignment; 6. Be mindful of driving habits. The functions of tires are: 1. Support the entire weight of the vehicle and bear the load of the car; 2. Transmit traction and braking torque, ensuring the adhesion between the wheels and the road surface; 3. Reduce and absorb vibrations and impacts during driving, preventing severe vibrations and early damage to car components; 4. Adapt to the high-speed performance of the vehicle and reduce driving noise, ensuring driving safety, handling stability, comfort, and fuel efficiency.

Tires with cracks must never be used further—it's extremely dangerous. Having driven for many years, I've seen plenty of cars running on cracked tires, only to end up with high-speed blowouts, vehicle damage, and injuries. Once a tire cracks, its structural integrity weakens, especially if there are deep or extensive cracks on the sidewall or tread, as it could deflate or burst at any moment. Hot weather increases pressure, making failures even more likely. Stop and inspect the tires immediately—if the cracks are deep or densely spread, head to a repair shop for a replacement. Regular tire maintenance is crucial: avoid prolonged sun exposure and maintain proper tire pressure to extend their lifespan. Safety comes first—don’t gamble to save a few bucks.

Can I still use a tire with cracks? It might work temporarily, but it's not cost-effective in the long run. For example, if the cracks are very shallow, you might drive home or to a repair shop, but avoid highways. Otherwise, a blowout could lead to repair and medical costs far exceeding the price of a new tire. A new tire only costs a few hundred to a thousand yuan, but the losses from an accident could be much greater. I recommend measuring the crack depth at a shop first. If it's less than 1mm, you might wait a bit, but don't delay too long. Tire cracks are usually caused by aging, underinflation, or poor road conditions. Maintaining proper tire pressure can help prevent them. Peace of mind is more important than saving money.

Tire cracking is a common sign of rubber aging, which can be caused by sunlight exposure, high temperatures, or prolonged use. If the cracks are superficial with a depth within 0.5mm, they may be acceptable for short-term, low-speed city driving, but avoid long-distance or high-speed trips. If the cracks are deep or wide, the tire's strength is significantly reduced, and the risk of a blowout skyrockets, requiring immediate discontinuation. First, inspect the crack location yourself—ensure it's not on the sidewall or shoulder—then visit a professional shop for assessment as soon as possible. For prevention, regularly check tire pressure with a gauge and avoid exposing tires to direct sunlight.
