The reason for small cracks on the edge of tires is natural aging of the tire. If there are numerous small cracks and their depth is close to damaging the tire body, the tire should be replaced promptly. Tires are rubber products and will naturally age due to environmental factors and usage. Their normal service life is approximately 4-5 years. As the tire body continuously undergoes bending and deformation, small cracks will naturally form. Over time, the safety factor will decrease, and failure to replace the tire in time may lead to accidents such as blowouts. Generally, it is recommended to rotate the tires every 10,000 kilometers to evenly distribute tire fatigue, prevent uneven wear, and extend tire life. Avoid rapid acceleration, emergency braking, or sharp turns; avoid hitting curbs; avoid parking on curbs; avoid driving quickly on unpaved roads. It is advisable to check the four-wheel alignment every 20,000 kilometers to reduce abnormal tire wear caused by changes in four-wheel alignment parameters. After overloading the vehicle or driving on rough roads, have it inspected at an authorized service center to avoid abnormal tire wear due to changes in four-wheel alignment parameters. Regularly check tire pressure, as both overinflation and underinflation can lead to abnormal tire wear, shorten the tire's normal lifespan, increase fuel consumption, and raise the risk of blowouts at high speeds.

I noticed small cracks on the edges of my tires, which are usually due to aging issues. After all, tires are made of rubber, and they naturally become brittle over time, just like clothes developing holes. I drive to work every day and have observed that prolonged parking under the sun in hot weather accelerates rubber cracking due to UV exposure. Low tire pressure, such as forgetting to inflate the tires, also increases the risk of cracks by causing excessive bending. I believe this shouldn't be ignored—once cracks become numerous, it's crucial to replace the tires promptly to avoid blowouts and potential hazards on the road. It's best to check the tire pressure monthly and maintain it at the proper level. Additionally, avoid using harsh chemicals to clean the tires, as this can speed up aging. Overall, regular maintenance is key.

From the perspective of rubber material, I understand that edge cracks on tires may stem from exposure to harsh environments, such as prolonged intense sunlight leading to the breakdown of rubber molecular structures. If a tire is consistently driven under low pressure, micro-cracks will form at pressure points. I've also observed that parking outdoors during freezing winters, where ice and temperature fluctuations make rubber brittle and prone to cracking, exacerbates the issue. These factors collectively increase the risk. I believe maintaining proper tire pressure can mitigate this problem and recommend checking for aging signs every two years. If cracks deepen and compromise tire safety, they should be replaced immediately—don’t wait until a high-speed incident occurs. Parking in a garage or using a cover to block UV rays can also extend tire lifespan.

As someone who has been driving for a long time, I've accumulated some experience. Cracks in tires are often caused by natural aging, especially in cars that have been driven for three or four years. Prolonged exposure to sunlight and long-term low tire pressure are the main culprits, leading to the degradation and splitting of the edge rubber. I believe timely replacement is crucial; too many cracks indicate that the tire structure has weakened, making continued use unsafe. I often remind people around me to check their tires regularly to ensure driving safety.

When I noticed fine cracks on the edges of the tires, my first thought was safety hazards, as increasing cracks make tires prone to bursting at high speeds, posing significant risks. These cracks are usually caused by aging or environmental exposure, such as prolonged parking under direct sunlight or insufficient tire pressure leading to excessive bending. It's advisable to immediately check the tire pressure and replace tires with deep cracks. In daily maintenance, avoid parking in extreme temperature conditions. Safety first—don't compromise it to save money.
