What are the signs of poor tire grip?

Tire grip is primarily influenced by factors such as the tread pattern, tread depth, road surface conditions, and vehicle load. Weak adhesion between the tires and the road can lead to vehicle slippage. Improving grip can be achieved by increasing friction and expanding the contact area between the tires and the road. Below are specific methods to enhance tire grip: Increasing Friction: Enhance the road's friction coefficient, which refers to the road's ability to provide traction for the tires. A higher friction coefficient results in greater traction. Different road surfaces, such as asphalt, concrete, and gravel, have varying friction coefficients, each offering different levels of tire grip. Additionally, increasing the tire's own friction coefficient can be achieved by opting for softer tires. Softer tires provide stronger grip but tend to wear out faster. Expanding the Contact Area Between Tires and Road: The simplest method is to switch to wider tires. Another approach is to choose tires with fewer tread patterns, which increases the actual contact area between the tires and the ground. However, this may negatively affect grip performance on wet or slippery surfaces. Lastly, and most importantly, within a given contact area, optimizing tire pressure and precise suspension tuning can fully unleash the tire's potential.
In my daily driving, the most obvious sign of poor tire grip is that the car tends to skid when encountering rainy conditions or sharp turns, causing slight drifting or even loss of control. Once on a rainy day, I was turning at an intersection at a moderate speed when the front wheels suddenly lost traction, nearly causing me to hit the roadside railing—I was so scared that I immediately tightened my grip on the steering wheel. During acceleration, if I press the throttle too hard, the wheels spin with a screeching sound. Braking performance also worsens, requiring earlier application to get a response; otherwise, the increased stopping distance raises the risk of rear-end collisions. Severe tread wear makes the tire surface smoother, reducing friction, which is especially problematic on wet roads. Regularly checking tire pressure and maintaining it at the recommended level is crucial—low pressure also reduces grip. I usually check it monthly to prevent accidents. After switching to new tires, my driving became much more stable, significantly improving my sense of safety.
As someone who often drives to pick up family members, poor tire grip is extremely dangerous. The most concerning issue is the body swaying during turns, making kids in the backseat feel uncomfortable as they get tossed around. Extended braking distances become even more noticeable in rainy or snowy conditions, causing the vehicle to slide further. I once experienced a skid while turning on wet pavement—the steering briefly veered, but fortunately, I slowed down in time to avoid a serious incident. Insufficient grip can also cause tires to squeal or spin during acceleration, which not only wastes fuel but also increases accident risks. To prevent these issues, I’ve developed a habit of checking whether the tire tread depth is sufficient and the pressure is appropriate. When traveling with kids, safety comes first—good grip ensures smoother and safer driving, reducing anxiety.
After decades of driving, the most common experience of poor tire grip is that the vehicle slides further after braking, and the body feels light and uncontrollable when turning slightly faster. Excessive tire wear makes the surface too smooth, leading to insufficient friction and frequent skidding; during acceleration, the unpleasant sound of wheel spin affects comfort. During inspections, pay attention to tread depth—less than 1.6mm is dangerous. Both underinflation and overinflation can exacerbate the problem. Timely tire replacement and pressure adjustment can improve driving safety and enhance handling.
