Track skills: how to give full play to the tire’s maximum grip

Driving pleasure largely comes from the performance of tires, and the improvement of tire grip is the basic direction to improve handling. Especially in the racetrack, such attributes will be magnified at the geometric level. No matter how powerful the performance of the tire is, the grounding part is about the size of a credit card. Because of the small grounding area, how to actively give full play to the maximum grip of the tire has become the key to success.

There are many articles about the types of tires, but there are few articles on how to give full play to the performance of tires! Are the racers too stingy? Or are they not keen on writing? Anyway, after years of track experience, I have summarized the following points.
Pay attention:
The following driving methods are specific to the racetrack. Do not try on the normal road!
1. Keep the tire pressure and temperature consistent with the manufacturer’s standards
Some drivers often like to lower the tire pressure to achieve the purpose of rapid heating up and increasing grip, but the effect is often counterproductive! Because this kind of sports tire with strong cross ply must be under sufficient air pressure so it can make effect. Too low tire pressure will slow down the tire response, and more seriously, it will lead to too high tire temperature and loss of grip.
2. Locking the tire and excessive skidding will reduce the tire grip

In the curve, the greater the angle of dumping, the more delicate the operation is. When the motorcycle approaches or reaches the maximum inclination angle, the grounding area of the tire is only a small part. At this time, any reckless sudden refueling, fuel reduction and braking will destroy the balance between the friction between the tire and the road, and eventually lead to skidding. Experienced drivers prefer to use the tire grip before the limit rather than let it slip, because it will waste time to correct it when the tires slip.
3. Use the reclining posture to turn the corner
It has been proved in the main two rounds of events in recent years that using exaggerated inward bending posture can effectively resist the centrifugal force in the bend. Under the same tire inclination limit, it has higher stability and faster bending speed than using other bending postures.
4. Adjust your position to maintain maximum grip
“In the corners, I was constantly adjusting my stance to find the best grip.”  This is a line from the autobiography of a famous race car driver.  Indeed, in the corners, in addition to using the accelerator, the racer constantly adjusts his body position (lean forward or move back) to change the load to achieve the best grip.
When braking into a corner, the weight of the car will shift to the front, and you need to sit as far back as possible, pushing back the rear wheels that will or have been off the ground.
When bending the center, the car is at the maximum inclination angle, apply force to the center of gravity on the vertical side of the tire, that is, the pedal on the outside is strengthened, and the outside legs also press the car body hard. All tires have a physical property called vertical load. That is, the greater the force applied vertically to the tire, the greater the tire wheel grip.
When accelerating out of the corner, the center of gravity of the car will shift to the rear. At this time, it is necessary to move the body speed to the front and press the front of the car to be lifted. The ultimate goal is to keep the front and rear wheels in contact with the ground to obtain maximum grip.

5. Turning with throttle

Before entering the bend center, purposefully start to open the throttle in a small range, and evenly, and then gradually increase the throttle to pass the bend. This is the turning secret constantly emphasized in the turning Bible, but it does not clearly explain why it should be done. In fact, the purpose of this is to give full play to the maximum grip of the tire.
When the car is at the maximum inclination angle, the driver has opened the accelerator according to the front shock absorption stroke

What is the principle?

Just as we all know that the recognized best braking force ratio is the first 7 and the second 3, how small is the best ratio of front and rear tire load when the car turns a corner? The answer is the first four and the last six. This means that in order to achieve such a load ratio when cornering, the driver’s task is to use the accelerator to move 10-20% of the weight back, so that the front and rear tires always maintain the best load ratio of the first 4 and the second 6! This small throttle can keep your tires traction, and still give full play to the maximum grip and stability at the lowest inclination. In fact, this is very easy to understand. You can try to do a small test, turn around in the open space and keep a certain throttle opening, which will be lower and more stable than fully closing the throttle.

How small is the throttle?

There is no fixed answer here! Because in reality, the horsepower of every corner and every car is different, but there are several principles we can follow: there is a certain throttle, but the car tires don’t slip and the line doesn’t throw out (go big). In order to achieve such a balance, the driver needs to practice and experience constantly.
Such a driving habit may be new to many motorists. There is no doubt that the level of a driver depends on his proficiency in this driving style. Mastering the tire characteristics on the track allows you to achieve greater inclination and open the accelerator earlier, which is the key to winning the race against time.
Back to the reality of riding, the above tire characteristics are also suitable for our daily riding. Riding fast is not necessarily dangerous, and riding slowly is not necessarily safe! Understanding the characteristics of your car’s tires plays a vital role in our daily safe and fast riding. Wrong driving habits, such as opening and closing the accelerator, braking and suddenly releasing the brake in the corner, may deplete the last grip of the tire in the corner. The tire will never communicate with you before losing grip, so build people who love driving to learn orthodox driving habits. Because maybe one day your car will teach you a hard lesson.
