What Does Wheel Track Mean?
2 Answers
Automotive wheel track refers to the distance between the centerlines of two front wheels or two rear wheels. The distance between the centerlines of the two front wheels is called the front wheel track, while the distance between the centerlines of the two rear wheels is called the rear wheel track. Tire Extended Information: 1. Importance: Automotive tires are one of the crucial components of a vehicle, directly in contact with the road surface. Together with the vehicle suspension, they help absorb shocks during driving, ensuring good ride comfort and smooth operation. They also ensure excellent adhesion between the wheels and the road surface, improve the vehicle's traction, braking, and off-road capability, and bear the vehicle's weight. The significant role tires play in automobiles is increasingly being recognized. 2. Passenger cars generally use radial tires: The specifications of radial tires include width, aspect ratio, inner diameter, and speed limit symbols. Taking the Toyota CROWN 3.0 sedan as an example, its tire specification is 195/65R15, indicating that the width between the two sidewalls of the tire is 195 millimeters, 65 represents the aspect ratio, "R" stands for the word RADIAL, indicating it is a radial tire. 15 is the inner diameter of the tire, measured in inches. Some tires also have speed limit symbols, represented by letters such as P, R, S, T, H, V, Z, each denoting a specific speed limit value.
Wheel track is essentially the lateral distance between the center points of the left and right wheels. Simply put, it's like the stance of a person's legs - a wider stance provides better stability! From my experience, cars with wider wheel tracks feel exceptionally stable at high speeds, especially when driving through puddles on rainy days without feeling floaty. I remember driving a friend's performance car once - that wide wheel track made it feel glued to the road during high-speed cornering, significantly more stable than regular sedans. However, the downside is obvious: overly wide cars become risky in narrow alleys. I once nearly scraped the mirrors driving through old town areas. In the car modification scene, some enthusiasts use wheel spacers to widen the track for better looks, but this affects suspension load distribution and should be done cautiously.
