Why does the toe in eat the outside of the tire if the toe in is too big, and if the toe in tires ar

The toe-in is too large, simply put, the wheels are stretched outward, because there is camber, so the force on the outside is a little greater than the inside after the bolder! So the outside of the tire will eat the tire! Otherwise, eat the inside!

Landlord, your car toe is too large, then its camber angle will become larger, so it leads to abnormal wear, and the force on the outside is greater than that on the inside, so it will be present on the phenomenon of eating tires on the outside, you go to Giti Weibo to take a look, the above maintenance knowledge is very comprehensive.

The tires eat the outside, basically not the toe-in problem, the inclination problem, or your chassis problem.

If the toe-in is too large, the camber angle of the front wheel will increase, resulting in abnormal wear of the shoulder.

There are many reasons for eating a fetus, mainly as follows:

1. Tires are not used in the corresponding road conditions, such as car tires, but are often used on gravel roads;

2. If the tire inflation pressure is too low or too high, there will be a potential risk of eating tires, and the wear and tear forms will be different;

3. Bad driving habits, such as frequent sudden braking, sudden braking, frequent corners without slowing down, etc.;

4. The four-wheel alignment of the vehicle is not good, and the toe or camber setting is unreasonable;

5. Wear of the ball shaft of the vehicle suspension or assembly, etc.;

6. The dynamic balance of the tire is not trimmed;

7. The use environment, such as strong heat, strong cold, chemicals, humidity and other harsh environments;

8. The quality of the tire itself, such as poor uniformity and non-good tires;

9. The mass distribution of the vehicle is uneven, and the position of the center of mass is unreasonable;

10. Overload.

Lateral shoulder area.

If the front speed is too much, the front tire will be worn out before it will not be long before the tire will be smoothed, there is no fixed value for the front speed, the truck can only be measured with a tape measure, and the car should be aligned with four wheels.

It will cause feathery wear on the outside of the tire, vibration and deviation of the vehicle at high speeds, and the sound of tires grinding when cornering.

Toe-in. The function is mainly to make the vehicle have the function of automatic return to the right, to ensure the stable straight line driving of the car, that is, when the steering wheel occasionally encounters an external force (such as touching a stone) when the action of the deflection occurs, it can automatically return to the position of straight line immediately after the external force disappears. This centering effect is guaranteed by the positioning parameters of the steering wheel.

The front wheel toe is one of these positioning parameters.

Will eat the internal test. At this time, it is necessary to make a four-wheel alignment system for the motor vehicle to restore the front macro beam of the vehicle to normal. Otherwise, the vehicle will eat tires for a long time, which will cause excessive tire wear. In severe cases, it will lead to a puncture, which will lead to a decrease in the driving stability of the motor vehicle and cause an accident.

When to do the quad wheel alignment.

When the steering wheel of a motor vehicle is misaligned, the wheel of the vehicle will lose control. All of the above actions require the vehicle's four-wheel alignment system. The vehicle's four-wheel alignment system is not a maintenance item of the vehicle, but a maintenance item of the motor vehicle, which does not need to be done regularly.

How long does it take to do a quad wheel alignment.

The maintenance time of the four-wheel alignment system is about 20 minutes, and the four-wheel alignment of the vehicle can be completed. After the normal positioning is completed, the wheels of the motor vehicle will be dialectical, and there will be no deviation and tire eating during driving. At the same time, the steering wheel of the vehicle can be corrected.

Millions of car purchase subsidies.

Lateral shoulder area.

The front speed is too much to wear the front tire, it will not take long before the tire will be smoothed, the front speed has no fixed value, the truck can only be measured with a tape measure, the car should be aligned with four wheels, which will lead to feathery wear on the outside of the tire, and the vehicle will vibrate at high speed, run off, and have the sound of tire grinding when turning.

The function of the toe is mainly to make the vehicle have the function of automatic return to the right, to ensure the stable straight line driving of the car, that is, when the steering wheel is deflected by the action of accidental external force (such as hitting a stone), it can automatically return to the position of straight line driving immediately after the external force disappears. This centering effect is guaranteed by the positioning parameters of the steering wheel. The front wheel toe is one of these positioning parameters.

Regarding the landlord's concern about "what is the impact of too large rear wheel toe?" "Here's my personal opinion:

If the toe-in of the rear wheel is too large, then its camber angle will become larger, abnormal tire wear will occur, and the force on the outside side will be greater than that on the inside, so there will be a phenomenon of the outside eating the tire

1. The so-called toe refers to the difference between the rear distance value and the front distance value between the two wheels, and also refers to the angle between the center line of the rear wheel and the longitudinal center line;

2. The role of the rear wheel toe is to ensure the driving performance of the car and reduce the wear of the tire, when the tire is rolling, the tire will be driven inward by its inertia force, if the toe is appropriate, the deflection direction of the tire when rolling will be offset, and the phenomenon of tire wear on the inside and outside will be relatively reduced;

3. The toe-in adjustment value of different cars is different, and it can generally be adjusted by the length of the steering tie rod.

The front wheel outside the tire needs to be noisy, and the front stool needs to adjust the front toe of the vehicle, which can be carried out by going to the maintenance plant or 4S shop. The front wheel toe refers to the distance difference between the front end face of the front wheel and the rear end face in the lateral direction of the car, and can also refer to the angle between the forward direction of the body and the front wheel plane, which is also called the toe angle. Car tires wear out due to the following:

1. Early wear of the first part of the tire (crown): the main reason is excessive inflation. Properly increasing the inflation capacity of tires can reduce the rolling resistance of tires and save fuel.

However, when the inflation is too large, it will not only affect the vibration damping performance of the tire, but also make the tire deformation too large, reduce the contact area with the ground, and the normal wear can only be borne by the tread ** part, forming early wear;

2. Excessive wear on both sides of the tire (shoulder): the main reason is insufficient inflation or long-term overloading. When the inflation capacity is small or the load is heavy, the contact surface between the tire and the ground is large, so that both sides of the tire are in contact with the ground to participate in the work and form early wear.

Tire pressure is 20% higher or lower than the rated value, mileage loss 20% 25%;

3. Excessive wear on one side of the tire: the main reason is that the front wheel alignment is inaccurate. When the camber angle of the front wheel is too large, the outer edge of the tire forms early wear, and when the camber angle is too small or absent, the inner edge of the tire forms early wear;

4. The shoulders of the left and right front tires are wavy and worn, and the inside of the left rear wheel and the outside of the right rear wheel are seriously worn. The main reason is that the front and rear axles are not parallel, and the wheelbase on the right side is larger than the left, which is more than the standard. The wheelbase standard (measured at the front and rear axle spring seats) has a maximum difference of 4 mm between left and right.

The solution is: the leaf spring car can be solved by screening and adjusting the length of the leaf spring. The air suspension car adjusts the thrust rod length;

5. The left and right front tire shoulders are wavy worn, and the inside of the right rear wheel and the outside of the left rear wheel are seriously abnormally worn. The reason is that the front and rear axles are not parallel, and the wheelbase on the left side is larger than the right, which is more than the standard.
