Which direction loosens the tire bolts?
2 Answers
For some passenger cars, tightening is clockwise, while loosening is counterclockwise. Introduction to car tires: Car tires are the main components that support the weight of the vehicle and are the parts that come into direct contact with the ground. The size of tires used varies depending on the positioning of different vehicle models. Tire bolt tightening/loosening direction: Generally speaking, for most car tires, the tightening/loosening direction of the bolts is determined by clockwise and counterclockwise rotation - counterclockwise loosens while clockwise tightens. However, for large trucks, the bolt directions differ between left and right sides: the left side uses reverse threads while the right side uses standard threads. Tightening follows the direction of the vehicle's forward movement, while loosening follows the reverse direction.
Having worked in an auto repair shop for many years, I often encounter beginners asking this question. The direction to loosen tire bolts is actually quite simple: turn counterclockwise to loosen. Most household vehicles follow a left-loosening, right-tightening design, similar to twisting a mineral water bottle cap. When encountering particularly tight bolts, remember to use a tire wrench and apply your full body weight to press down. I once encountered a rust-seized bolt that required rust penetrant spray to loosen. During actual operation, it's best to first loosen the diagonal bolts to maintain balance, and after removal, inspect the threads for any damage. I recall helping a customer change a tire and discovering their jack wasn't properly secured - it nearly caused a serious accident. Tool selection is crucial; avoid using adjustable wrenches as they tend to slip. When tightening back, do so diagonally in stages, and finally use a torque wrench to achieve the standard torque for reliability.
