Can tires with cracks be driven on highways?
2 Answers
Tires with cracks cannot be driven on highways. Below are the impacts of cracked car tires and an introduction to tire mileage and lifespan: Impacts of cracked tires: Cracks on car tires indicate severe aging of the tire, making it unable to withstand prolonged high-speed driving. Therefore, driving on highways with such tires increases the risk of accidents. Tire mileage and lifespan: Generally, the lifespan of a tire is 5-6 years, with a mileage of 70,000-80,000 kilometers. However, it is important to note that the tire should be replaced based on whichever comes first—mileage or age. Even if the car is not driven frequently, the rubber can harden and become brittle, increasing the risk of a blowout.
When there are cracks in the tires, I strongly advise against driving on the highway. At high speeds, the pressure and temperature on the tires increase significantly. If the tires are aged and cracked, it can easily lead to a blowout. A blowout is no minor issue—it can cause the vehicle to lose control instantly, potentially leading to a rollover or rear-end collision, endangering you and others. I would first carefully inspect the cracks—small, shallow cracks might be manageable for short city trips, but deep or multiple cracks require immediate replacement. Regular tire maintenance, such as checking tire pressure and wear, can help prevent aging. Safety comes first, far more important than rushing. If you must drive on the highway, it's best to replace the tires or have them professionally assessed beforehand—don't take the risk.
