Can tires with small cracks still run on highways?
2 Answers
Tires with small cracks cannot run on highways. Below is an introduction to the reasons why tires with small cracks cannot run on highways and the tire replacement cycle: Reasons: Tires are the only point of contact between the car and the ground, so all the performance of the car is transmitted to the ground through the tires. The condition of the tires has a very direct impact on driving. If the tires have been used for too long and have exceeded their lifespan, they need to be replaced. Additionally, if there are bulges, the internal cords may have already broken, leaving only the rubber, which is very dangerous and poses a risk of a blowout at any time. Tire replacement cycle: If the daily maintenance of the car tires is excellent, and the driving conditions are good, with minimal tire wear, then the owner should replace the tires within 5 years, with the mileage not exceeding 100,000 kilometers. Since tires have a shelf life of 5 years and rubber has an aging period, to avoid unexpected safety hazards, regardless of whether the mileage reaches 100,000 kilometers, it is best to replace the tires once they reach the 5-year mark from the date of manufacture.
When it comes to whether tires with small cracks can be driven on highways, I must warn you that the risk is significant. Small cracks on tires are usually caused by aging, such as prolonged exposure to sunlight or years of use, which hardens and cracks the rubber. During high-speed driving, tires endure much greater pressure and heat than usual, and the rapid rotation can easily cause the cracks to expand, potentially even tearing the entire tire structure and leading to a blowout. I've seen many cases where problems arise as soon as speed increases—ranging from loss of steering control and skidding to severe rollover accidents. I strongly advise against taking chances. Park immediately and check the depth of the cracks. If the cracks are deeper than the tire tread grooves or clearly visible to the naked eye, do not drive at all—head straight to a repair shop for new tires. For road safety, regularly check tire pressure and wear to prevent minor issues from escalating into major hazards.
