Can tires with fine cracks on the surface still be used?

[VanGenesis]

Yes. Fine cracks on the tire surface indicate that the tire has entered the aging stage, but they generally have little impact on daily driving, and the tire can still be used. Of course, if conditions permit, it is advisable to replace the tire at a professional service center as soon as possible for a better driving experience. Here is some relevant information: There are generally two reasons for fine cracks on the tire surface—normal tire aging and prolonged driving with insufficient tire pressure. Tires are made of rubber, and when exposed to wind, rain, and sunlight for extended periods, the rubber gradually loses its original elasticity and toughness, leading to the formation of fine cracks. Although tires in this condition can still function normally, if the cracks become more severe, the tire should be replaced as soon as possible.

If there are fine cracks on the tire surface, I recommend carefully inspecting the specific situation first. I remember when my car tires had this issue before—I checked whether the cracks were on the tread or the sidewall. Sidewall cracks are more dangerous because that's a weaker area of the tire. Try using a coin to test the depth; if it doesn’t embed too deeply, it might be usable for short distances. However, if there are many cracks or they’re deep, you absolutely shouldn’t use them, as they could suddenly blow out at high speeds. Also, don’t forget to check the tire’s age and wear condition—older tires are more prone to problems. It’s best to get a professional inspection once a year, and maintaining proper tire pressure can help slow crack deterioration. Safe driving is the top priority—don’t risk saving a few hundred bucks by skipping a tire replacement.

With over a decade of driving experience, tire cracks are usually caused by rubber aging or prolonged exposure to UV rays. Small cracks may not be noticeable at first, but if they appear in high-stress areas like the center of the tread, reduced rubber strength can lead to issues during turns. Monitor the speed of crack propagation, as hot weather accelerates their growth. Regularly cleaning dust off the tire surface can slow aging, but once cracks appear, the damage is irreversible—it's wise to budget for tire replacement in advance. New tires typically last 5-6 years, while older tires require frequent inspections to avoid sudden failures that could cause delays.

Don't panic when cracks appear, check them yourself first. Gently press the crack with your finger—if there's no obvious gap or deformation, it's temporarily safe, but avoid high speeds. If the crack is on the side or deep, visit a repair shop immediately. Also, check if the tire pressure is stable, as low pressure can accelerate crack propagation. Generally, it might last a month or so for short urban trips, but for safety, it's best to replace it soon.

From an economic perspective, spending one or two thousand yuan on new tires might be painful, but the cost of a blowout, repairs, and towing is even higher. Small cracks might last for months if they don't expand, but the risk increases if you frequently drive long distances or carry heavy loads. I once had a friend who tried to save money by not replacing them and ended up stranded on the road. Regular tire maintenance, such as avoiding prolonged parking under direct sunlight, can extend tire life and reduce crack formation. If you notice an increase in cracks, don't hesitate to replace them.

It depends on driving habits. For daily city commutes like mine, small cracks on the tread may last a while. But high-speed or mountain road enthusiasts must be cautious, as cracks are prone to breaking under vibration. Storage conditions also matter—tires kept in garages with less sun exposure develop lighter cracks. Regular tire rotation ensures even wear and early detection of crack issues. In short, monitor crack progression closely to prevent potential safety hazards.
