Why high-end car tire rubber are relatively thin steel ring are relatively large? Low-end car just the opposite.
The big ring is nice and the tires are widened. Advantages: stability, good handling. Disadvantages: fuel consumption increased, sacrifice a certain comfort. Low-grade car with small steel ring cheap, fuel-efficient. Small Japanese cars such as Nissan series of tires are very narrow, flat than the value of large, comfort will be better. Tire has a flat ratio, the smaller the value, the more flat.
The tires used in premium cars (especially sports cars) are different from ordinary tire sizes and are used in the pursuit of better grip and handling performance. For example, jetta and other vehicles use 185/55 / R15 (185 For the width, 55 for the thickness, R15 for the hub radius) of the ordinary tires, and sports car or emphasis on sports performance models will use a wider and more flat, larger hub wheels, such as some 215/45 / R16 tires, some The rear wheel is usually the size of the front and rear tires are different, the rear wheel slightly wider, that the drive wheel to obtain better grip, some ultra-running and modified car tire size exaggerated, such as 235/35 / R18, usually on the market Running trolley (mid-range, upscale) tire thickness is similar, but some high-end wheels larger (16, or 17 inches), may cause visual differences, feel tires particularly flat
