Can the old X Trail install 15 inch wheels?

Yes, it is best to do four-wheel alignment and dynamic balancing after the change.

It is recommended that you install wheels that are one inch larger or one inch smaller.

Description: 1. The width of the original wheel is inch, and the tire with 215 is already its upper limit, so it is ready to change the wheel with an ET value of 35mm. This means that the 225 and 235 tires can be replaced, and the wide part of the tire can be pushed outward to avoid scratching the body;

2. The 4 specifications of tires I proposed are only the specifications that can be replaced without increasing the height of the body, and I don't know if the tires of these specifications on the market are easy to buy;

3. I read a post from a classmate who had done a test, and his conclusion was that the diameter limit of the new tire was 721, which would scratch the car body. So the last one is riskier;

4. It is said that the change range of the new tire compared with the original tire should be controlled at 3%, according to this statement, the last one is also exceeded, and the other three are OK.

The Nissan X-Trail wheels can be modified to 20 inches. If the car has gone to the vehicle management office in advance for the record, and modified it by itself, it is a private modification, not only can not pass the annual examination, but it is still an illegal act. According to the relevant regulations, the owner of a motor vehicle with a license plate must apply to the vehicle authority for a change of registration if the body color, model, performance, use and structure of the licensed motor vehicle is replaced, or if the frame, body or engine is replaced.

The following is the filing process for car modification changes:

1. Check the appearance, the process is the same as the annual inspection, the extension number is pure, take pictures, and the link of the appearance modification of the trouser model cannot pass the inspection, and the original factory needs to be restored in advance;

2. Fill in the application form (modified car color), there is an application form for changing the color in the business hall, and send it to the processing window to wait for review and distribute a new driving license;

3. Under normal circumstances, the new driving license can be successfully handled in about half an hour, and only 15 yuan of production cost is required, and all the business is completed.

The Nissan X-Trail wheels are available in 17-inch and 19-inch sizes. The hub is the rotating part of the wheel core that is connected by the inner profile of the tire steel through the column, that is, the metal part that supports the center of the tire mounted on the shaft. It is also called a rim, a steel rim, a wheel, and a tire bell.

According to the characteristics and needs of different models, the surface treatment process of the wheel hub will also take different ways, which can be roughly divided into two types: round source baking paint and electroplating. The following is the relevant internal crack cavity sail capacity of the automobile wheel:

1. When the temperature of the wheel hub is high, it should be allowed to cool naturally before cleaning, and it must not be cleaned with cold water;

2. When the wheel hub is stained with tar that is difficult to remove, if the general detergent does not help, you can use a brush to try to remove it;

3. If the place where the vehicle is located is wet, the wheel hub should be cleaned frequently to avoid the corrosion of the aluminum surface by salt;

4. After cleaning if necessary, the wheel hub can be waxed and maintained to keep its luster forever.

Nissan X-Trail ( Check price |The wheel size is 16 inches. The hub is the part of the wheel where the axle is installed in the center of the wheel, which is often referred to as the "rim" or "steel rim". The wheel hub is easy to get dirty, and if it is not cleaned for a long time, it may be corroded and deformed, resulting in potential safety hazards.

The differences between steel wheels and alloy wheels are as follows:

1. The main advantage of steel wheels is that the manufacturing process is simple (generally using the casting process, for example, aluminum alloy wheels are generally produced by low-pressure casting process), the cost is relatively low, and the ability to resist metal fatigue is very strong;

2. The weight of the steel hub is large (the same steel material of the hub is much heavier than that of aluminum alloy material), the inertia resistance is large, the heat dissipation is also relatively poor, and it is easy to rust;

3. The alloy wheel hub has light weight, low inertia resistance, high production accuracy, small deformation and low inertia resistance when rotating at high speed, which is conducive to improving the straight-line driving performance of the car and reducing the rolling resistance of the tire, thereby reducing fuel consumption;

4. The thermal conductivity of alloy material is about three times that of steel, and the heat dissipation is good, which can play a certain role in the thermal attenuation of the vehicle's braking system, tires and braking system.

X-Trail tires have three specifications, namely 225 65R17, 225 60R18, 225 55R19, which belong to aluminum alloy. The size of the wheels matched by different configurations is different, and the replacement of the wheels needs to be replaced with brand tires of the same specification. Replacing large wheels increases the ground contact area, increases vehicle fuel consumption, and increases driving smoothness.

The advantages and disadvantages of replacing large wheels are as follows:

1. The bearing capacity of the large hub is stronger; Small wheels are usually made of steel in order to save costs, but large wheels are made of aluminum alloy wheels, especially aluminum alloy wheels made of forging process, the bearing capacity of this kind of hub is 5 times that of ordinary steel wheels;

2. The large wheel hub improves the cornering performance of the vehicle; After the wheel hub is modified, the grounding area is increased by acres, so that the smooth cornering performance of the vehicle is improved, and the cornering performance of the vehicle is significantly improved;

3. Large rims will reduce driving comfort; The large rim affects the ride comfort. In general, the outer diameter of the tire is a fixed value, that is, the larger the rim, the thinner the thickness of the tire, which will lead to the poor isolation of road noise, and the noise in the car will increase accordingly, affecting the quietness of the car;

4. Large wheels will reduce the performance of the car; Large-sized wheels affect acceleration and braking performance. While the size of the rim increases, the width will also increase accordingly, and the larger and wider the rim, the weight of the rim will naturally rise, which will require more power consumption to drive it, which will affect the acceleration performance;

5. Large wheels will increase fuel consumption; Larger rims increase fuel consumption. The large rim has an advantage in diameter, and the tread width corresponding to the reputation rent is also larger. The advantage is that the contact area between the wheel and the road surface is increased, which can increase the grip and help improve the stability of the vehicle.

But the cost is that the friction will increase, and the fuel consumption will increase to a certain extent.

X-Trail modified wheels can not pass the annual inspection, it is illegal. Automobile modification refers to the vertical change of the external modeling, internal modeling and mechanical properties of the prototype car produced by the automobile manufacturer according to the needs of the car owner, mainly including body modification and power modification. The following are the relevant regulations for car modification:

1. To change the motor vehicle, it must be carried out within the scope specified by the traffic management department, that is, the body color, engine, fuel type, driving number, etc. can be modified.

2. No unit or individual shall assemble a motor vehicle or change the registered structure, structure or residual dust wheel characteristics of the motor vehicle without authorization;

3. Without the permission of the public security traffic management department, unauthorized modification of the motor vehicle chassis, engine, suspension, transmission system, direction system, tire hub, headlights, body color spraying and appearance structure, as well as the relevant technical data of the motor vehicle and the announcement data of the competent department of motor vehicle products are all modifications.
