Ground tread tires are tires with removed barcodes. They should not be used for frequent highway driving. Other vehicles can use ground tread tires. Ground tread tires refer to tires where the white barcode located at the tire toe area has been ground off. Detailed information about ground tread tires is as follows: 1. Ground tread tires are defective tires: Tires with ground-off barcodes are not genuine products, and manufacturers will not take responsibility for any issues. Additionally, these tires are non-warranty products, being substandard items identified during factory inspections. Ground tread tires with minor defects can still be used. 2. Ground tread tires are cheaper but may have dynamic balance issues: Dynamic balance problems in ground tread tires can be corrected through balancing procedures. While dynamic imbalance won't cause tire blowouts, it can lead to side-to-side wobbling. They can be used normally at lower speeds and without heavy loads. 3. When purchasing ground tread tires, it's best to choose reputable brands: Most ground tread tires from major brands only have dynamic balance issues. Many generic brand ground tread tires may have numerous problems, such as uneven rubber content, radial issues, tire peeling, or small holes in the tires.

I've been driving for many years, and from a safety perspective, bald tires should never be used casually. Worn-out tire treads are like walking barefoot—significantly reduced grip makes them prone to skidding and losing control on wet roads, while braking distance also increases, posing higher risks on highways. National regulations stipulate that tread depth must not fall below 1.6mm. I often use a one-yuan coin to test: if the character 'Yuan' is completely embedded in the tread groove, it's time to replace them. Bald tires wear out quickly and may even blow out. A friend of mine had an accident on a national highway due to neglecting this, and the repair costs ended up being much higher than new tires. Tires are the lifeline of a car—for the safety of yourself and your family, don’t take risks if the treads are insufficient; replace them promptly. Conduct regular checks at least quarterly to ensure proper tire pressure and reduce wear.

I'm generally a frugal person, but using worn-out tires is really not worth it. On the surface, you save money by not replacing them, but over time, problems arise: fuel consumption increases due to higher rolling resistance, and poor tire balance can even damage the suspension system. If something goes wrong, like losing control in the rain, the company might deny your claim after an investigation, leaving you with even bigger losses in repair costs and fines. My advice is not to risk big for small savings—new tires used over several years spread out the cost more reasonably. Check wear with simple methods: feel the tread grooves or see if the manufacturer’s wear indicators are exposed. Safe driving is fundamental, and tire condition directly affects handling, especially before long trips—always check tire pressure and wear to avoid accidents.

Tire wear has significant technical implications, as tread design is crucial for grip and water drainage. When the tread depth falls below the minimum standard (typically 1.6mm), the tire cannot effectively channel water away on wet roads, drastically increasing the risk of skidding accidents. During my testing, I use a coin or professional caliper to easily measure the depth—address any issues immediately without waiting until the tread is completely worn and emergency stops become hazardous. Additionally, tire positioning and balance are vital; uneven wear accelerates aging. I recommend an annual professional wheel alignment to extend tire lifespan. Simple can prevent major issues.

I once rented a car with nearly bald tires, thinking I could save money by making do. While driving on a winding mountain road during a suburban trip, the car suddenly fishtailed, giving me a real scare! Upon checking, I saw the tread was almost gone, and the drainage grooves were shallow. That incident taught me that driving on worn tires isn't safe—it's a constant mental burden, always worrying while driving. Now, with my own car, I use a mobile app monthly to check tire wear. When the tread wear indicators become visible, it's time for new tires. I'm especially cautious in rain or snow—safety is far more important than saving a few hundred bucks. I also rotate the tires regularly to balance wear, maintain proper tire pressure, and avoid premature wear-out.

Preventing tire wear is quite simple. I've developed a habit of checking my tires every 5,000 kilometers. When assessing tire wear, don't just look at tread depth—also pay attention to low tire pressure, which can accelerate wear or cause bulges. Use the coin test: if the 'Yuan' character isn't completely hidden, the tire is still safe to use; otherwise, it's time for a replacement. Be mindful of your driving habits: rapid acceleration and hard braking speed up tread flattening, and rural road conditions require more frequent checks. I recommend combining seasonal with tire checks before the rainy season to ensure strong grip and reduce accidents. Additionally, different tire types like snow tires wear differently, so choosing the right tire for road conditions can extend lifespan and save money.
