The bigger the displacement, the bigger the tire

Regarding displacement as a measurement standard, in general, the larger the displacement, the larger the tire size will be. Of course, the size of the tire will directly affect the comfort, beauty, and passing performance of the vehicle. The international standard tire code, expressed in millimeters as the unit of section height and aspect ratio in percentage, the displacement of small cars is between 0.8-1.5, corresponding to its front tire size is 155/65R13 73T--175/70 R 14 77H Within this range. The front tires are small in size, and the friction with the ground is reduced when the vehicle is running, so it is more economical in terms of fuel. This is also the main reason why most consumers choose small-displacement cars, but the negative effects that follow are , Because its limited tread diameter will greatly reduce its passability and comfort, and it will often have no bottom when driving a small-displacement car over hurdles. Small-size tires make the steering gear lighter and lighter in most small rows. There is no power steering in the volume car. The tire specifications of large cars with displacement between 1.6 and 6.0 are correspondingly in the range of 185/60 R 14-- 245/50 R 18. Large-size tires will make the entire body look domineering, and good grounding properties ensure its acceleration performance and body stability at high speeds. The front and rear tire specifications of some special off-road vehicles and modified competition vehicles will differ. Under normal circumstances, they will be designed with a small front and a large rear. If it is a four-wheel drive model, it will also involve the problem of the differential between the axles, because the front and rear The size of the wheels is different, the movement of the car will be affected. When the car is walking on the ground, the time it takes for the rear wheels to make a circle will take longer than the front wheels. This will affect the normal movement of the front and rear axles.
