Is it a problem if there are many small cracks on the surface of a car's tires?

Small cracks on the tread of a car's tire are a natural aging phenomenon of the tire and are considered normal. Recommendation to replace tires: This is mainly because tires are rubber products. Over time, the rubber of the tire hardens, and the tread or sidewall becomes covered with small cracks. At this point, the performance and strength of the tire decrease. If the cracks on the tread are very fine, they are not a major concern and the tire can still be used for city driving, but it should not be used for high-speed driving as it could easily lead to a blowout. Of course, if possible, it is recommended to replace the tire. Tire lifespan: However, if the cracks on the tread are very deep, the tire should no longer be used. At this stage, the tire is severely aged and has lost the properties that rubber should have, posing a significant safety hazard if continued to be used. Generally, the lifespan of a tire is 3-5 years. Minor cracks may appear around 3 years, and after 5 years, the tire is severely aged. To ensure driving safety, it should be replaced promptly.
Those tiny cracks on the tire surface are no small matter – they're clear signs of aging. Rubber hardens and cracks over time, especially when exposed to prolonged sunlight or frequent temperature fluctuations. The cracks may appear fine, but they weaken the tire structure. During high-speed driving when tire temperatures rise, these cracked areas can become weak points leading to blowouts. We recommend carefully inspecting the crack depth, particularly on the tire sidewalls. If you find deep cracks exposing the inner cord layers, it becomes extremely dangerous. While tires typically last 3-5 years, their actual lifespan shortens with outdoor parking or extended use. Never compromise safety to save money – it should always come first.
