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 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.

I had a scary experience with small cracks in my tires. That year, I was driving long-distance on the highway when I noticed fine cracks on the tires. I ignored them and kept going, but when I hit 120 km/h, I felt the wheel shaking. After pulling over, I saw the cracks had grown longer—fortunately, I stopped in time. At high speeds, tires heat up quickly, and aged rubber becomes fragile, causing small cracks to rapidly expand, leading to delamination or blowouts. This is a matter of life and death for you and others, so I strongly advise against risking highway driving. First, pull over to a safe area and check the cracks—if they're too deep or wide, don't drive. It's best to visit a professional auto repair shop for a full , including checking the tire's age. Generally, tires older than five or six years should be replaced. Safety should always come first—don't cut corners to save a little money.

I think driving on the highway with a tire that has small cracks is really dangerous. Common cracks caused by tire aging can easily expand due to the high speed and heat generated on the highway. A single bump could lead to a blowout. Life is too precious to gamble with. I've heard from a friend who had a close call due to a similar situation, and it was a big lesson. I suggest you take immediate action—avoid driving at high speeds and get it checked thoroughly at a repair shop. If it needs to be replaced, don't hesitate to do so. It's not worth the risk.

There are small cracks on the tires, and I absolutely believe they should not be used for highway driving. Having driven for decades, I understand these minor marks are warning signs. At high speeds, increased friction and heat can turn cracks into major hazards, easily leading to blowouts. Check the depth promptly—if it's deep, don't use them. Safety comes first.

There are small cracks on the tires, I suggest avoiding highway driving. High-speed driving subjects tires to high pressure and temperature, which may cause small cracks to suddenly expand and lead to failure. Check the depth of the cracks: insert a coin into the crack, if it exceeds the limit, don't risk driving. Immediately go to a professional shop for evaluation or replacement. Safety first.
