The difference between 18 inch wheel rims and 19 inch wheels is mainly reflected in the size, manufacturing cost, price, driving comfort and fuel consumption, and safety. The following specific instructions:
1. Dimensions
Inch refers to inches, and 1 inch is equal to 2.54 centimeters. The 18 inch hub means that the diameter of the hub circle is 45.72 cm, which is slightly smaller than the 19 inch hub.
2. Manufacturing cost
Because of the different weight of materials, the manufacturing cost of 19 inch wheel rims is much higher than that of 18 inch wheels.
3. Price
Generally speaking, the larger the size of the wheel hub of the same model, the more aluminum it consumes, the higher the relative price.
4. Driving comfort
The larger the wheel and the thinner the tire wall, the more realistic the feedback on the road surface when the car is driving. Owners and friends who pay attention to handling and appearance can choose 19 inch wheels. The tires with small wheels and thick sidewalls can effectively filter road vibrations, and 18 inch wheels are better in terms of comfort.
5. Fuel consumption
The larger the wheel hub and the wider the tread, the greater the friction with the ground, so the higher the fuel consumption. The same car with 19 inch wheels will consume more fuel than 18 inch wheels. The wheel hub is small, the comfort is higher, and the fuel consumption is lower.
6. Security
Compared with 18 inch wheels, 19 inch wheels have better driving control, better braking performance and stronger stability. The larger the wheel hub, the easier it is to control the car when a puncture occurs at high speed, reducing the probability of a dead car accident
Summary: Equipped with the same tires, 18 inch wheels are slightly inferior to 19 inch wheels in terms of handling performance, safety, and stability, but they are better in terms of comfort, quietness, and fuel economy, and the probability of tire damage is higher. Low.
