Should tires with multiple cracks be replaced?
2 Answers
Whether car tires with cracks need to be replaced depends on the situation. If the cracks are caused by external impact or scratches, they should be replaced immediately. There are two main scenarios for tire cracks: 1. Natural rubber aging - When tires have been used for a relatively long time, many fine cracks may appear on the tire rubber surface, which are called "crazing". 2. Cracks caused by external impact or scratches - Since the tire sidewall is the weakest part of the tire, the presence of cracks indicates damage to the tire's structure. Additionally, when the vehicle is moving, friction between the tire and the ground generates heat, causing the gas inside the tire to expand when heated.
Tires with numerous cracks definitely need to be replaced. From a driving safety perspective, widespread cracking indicates tire aging, where the rubber has hardened and is prone to blowouts or skidding while driving. I remember one rainy day when I was driving, my cracked tires couldn't stop properly on wet pavement, nearly causing a rear-end collision—it was really frightening. The designed lifespan of tires is generally 5 to 6 years. If they exceed this timeframe or show obvious cracks, they should be replaced. When inspecting, pay attention to the location of the cracks—sidewall cracks are more dangerous because they endure greater pressure. Don't wait until an accident happens to regret it. Replacing with new tires not only improves traction but can also enhance fuel efficiency. For the safety of yourself and others, don't hesitate to visit a repair shop for a replacement.
