Should tires with multiple cracks be replaced?

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.

From an economic perspective, tires with excessive cracks should be replaced. New tires may cost a few hundred yuan, but if left unchanged, the cracks can accelerate wear, leading to insufficient tire pressure or even blowouts, resulting in higher repair costs or even costly accidents. I've experienced this firsthand—when the tire tread was severely peeling and I didn't replace it in time, hitting a pothole caused a leak, and the repair cost exceeded that of a new tire. Cracks are a sign of aging, and new tires can improve fuel efficiency and driving stability. Considering long-term costs, replacing tires is a worthwhile investment—don’t skimp on it. Regularly check the severity of cracks; if they’re deep, take immediate action. Remember to choose durable brands to extend the time until the next replacement.

Tires with cracks really need to be replaced. Speaking from personal experience, last summer my car was parked outdoors under the scorching sun, and the sidewalls of the tires were covered in cracks. The handling felt poor, and the tires slipped dangerously in the rain. Thankfully, a friend reminded me to change them. Now, I check the tread condition every time I wash the car. Cracks reduce the rubber's grip, posing significant risks at high speeds—don’t take it lightly. Check them immediately, and if they’re severe, replace them right away.
