2. The tire outer diameter must be basically unchanged, because it is related to the vehicle ESP stability system, instrument display and so on. Therefore, the outer diameter of the original tire must be basically unchanged, and the error should be within 3% as far as possible. The smaller the error, the better. The outer diameter of the tire is well calculated. For example, the tire with 2 15/60R 16 has an outer diameter of16× 25.4+215× 60 %× 2 = 664.4mm, and the outer diameter of the upgraded tire is very close to 664.4 mm. ..

3. The center hole diameter and hole spacing of the hub must be the same as the original hub, and the hole spacing must also be the same. Needless to say, it is impossible to install it differently. For the diameter of the central hole, don't believe that adding a circlip can achieve the same effect, and don't do it. The stability of this will be very problematic.

4. After upgrading the tire hub, not only dynamic balance but also four-wheel positioning should be done, and the positioning parameters should be adjusted to the range set by the manufacturer.

5. Be sure to buy the wheels produced by regular manufacturers. Wheels with quality problems are safe.

Hub classification:

1, steel wheel hub

The main advantages are simple manufacturing process, relatively low cost and strong metal fatigue resistance, which is also commonly known as cheap and good quality. However, the steel wheel hub has obvious disadvantages, such as ugly appearance, heavy weight, large inertial resistance, poor heat dissipation and easy rusting.

2. Alloy wheel hub

Alloy wheel hub can just make up for the shortcomings of steel wheel hub, with light weight, low inertia resistance, high manufacturing accuracy and small deformation when rotating at high speed, which is beneficial to improve the straight-line driving performance of the car and reduce the rolling resistance of the tire, thus reducing fuel consumption.

The thermal conductivity of alloy material is about three times that of steel, and it has good heat dissipation, which can play a certain role in the thermal attenuation of vehicle braking system, tire and braking system. However, compared with steel wheels, alloy wheels are much more expensive, so often in many low-end original cars, steel wheels will appear on low-profile models, while alloy wheels are standard on high-profile models.
