Which Tire Doesn't Turn When a Car Makes a Right Turn?
2 Answers
When a car makes a right turn, both tires rotate, but the right tire turns in a smaller arc while the left tire turns in a larger arc. Relevant details are as follows: Minimum Turning Radius: When a car turns, there is a minimum turning radius. The minimum turning radius refers to the radius of the circular track rolled by the center plane of the outer steering wheel on the supporting surface when the steering wheel is turned to its limit position and the car turns at the lowest stable speed. To a large extent, it characterizes the car's ability to pass through narrow curved areas or bypass insurmountable obstacles. The smaller the turning radius, the better the car's maneuverability. Introduction to Turning Radii of Different Vehicle Types: Generally, the turning radius of a microcar is 4.50 meters, a compact car is 6.00 meters, and a light-duty vehicle is 6.50 meters. When a car makes a right turn, the left tire turns in a larger arc, covering a longer distance, while the right tire turns in a smaller arc, covering a shorter distance.
Having driven for decades, I've encountered all sorts of tire issues. Regarding which tire doesn't rotate during a right turn, the answer is actually the spare tire. That's because the spare is usually stored in the trunk or mounted underneath the vehicle, not being part of the driven wheels. During a right turn, all four wheels turn according to the steering wheel's movement, but the spare remains stationary - like a backup guardian that only springs into action during a flat tire. I often advise friends to regularly check the spare tire's air pressure and tread condition to prevent it from becoming deflated and useless; if the spare fails when you have a flat, it'll cause unnecessary delays. Make it a habit to quickly inspect the spare during routine maintenance, ensuring its pressure stays around 30-35 psi for peace of mind. Also, avoid taking turns too fast to prevent excessive tire wear.
