Installing wheels must first understand the values on the wheels, including size, width, E T value, PCD and hole position. Wheel width, commonly known as the J value, is a direct impact on the choice of tires, the same size tires, J value is different, the choice of tire flat ratio and width is different, you can refer to the following table:
When you usually look at the model introduction have you found a phenomenon: is that some models of different configurations in addition to some performance, configuration differences, wheel size is also different. The more expensive the configuration the larger its wheel size, the appearance also looks more sporty and better.
But the big wheels straight is necessary to choose? What is the difference between the normal size and the usual use? What are the changes and differences after the wheel upgrade?
What are the changes and differences after upgrading the wheels?
Common wheel sizes
Usually the original factory standard wheel sizes are: 15 inches, 16 inches, 17 inches, 18 inches, 19 inches, the small size is usually assigned to the family car, the larger size will be equipped with a more advanced car.
If you are not clear about the size of their car wheels, you can look at the numbers on the tires, usually our tires will be marked on the number of three groups, similar to: 225, 60, R17, the size unit is millimeters. 225 is the width of the tire in contact with the ground; 60 is the tire flat rate; R17 corresponds to the size of the wheel, so this is 17-inch wheels.
Advantages and disadvantages of large size wheels
Advantages
The larger the wheel, the lower the flat ratio, which means thinner tires and clearer and more controlled feedback on road conditions.
This is why many sports and racing cars have large wheel sizes.
Disadvantages
However, the shortcomings brought by large wheels cannot be ignored, because in order to balance, the wheel size is large, the flat ratio becomes lower, the tire wall is thin, then it rides less comfortable, and the relative fuel consumption will also increase. If you are very concerned about the economic fuel consumption, you should be more careful in the choice of wheel size.
Understand the parameters clearly before retrofitting
Installing wheels must first understand the values on the wheels, including size, width, E T value, PCD and hole position. Wheel width, commonly known as the J value, is a direct impact on the choice of tires, the same size tires, J value is different, the choice of tire flat ratio and width is different, you can refer to the following table:
If the original 17-inch wheels, but want to upgrade the size, such as 18-inch wheels, then it corresponds to a higher J-value, according to the formula of the old and new tire diameter difference should be controlled at 3% up and down, so as to protect the safety of driving, so it is optional tires are wider, the natural tire wall is also thinner. What are the changes after the wheel size upgrade?
The wheels are larger, the tires are wider, the walls are thinner, so if you are not careful, it will have a higher chance of bulging or flat tires than small wheels.
Jwheel, as an professional wheel manufacturer, concentrates in R&D and manufacturing of aluminum alloy wheels, including casting wheels, forging wheels and flow-form wheels. The products of it have passed the certifications of SEI、SEMA,VIA, JWL, JWL-T, TUV and so on. Since establishment, Jwheel has been developing steadily, with rich experience of designing and producing aluminum alloy wheels. It has earned the appreciation of both domestic market and foreign market with its high technology, good quality and customer service.
