When changing tires, is clockwise tightening or loosening the bolts?

[Alana]

When changing tires, loosening the bolts is counterclockwise, and tightening the bolts is clockwise. When installing tire nuts, the tightening is not determined by depth but by torque. Different specifications and grades of bolts and nuts have specified torque range values. Simply tighten according to the bolt's grade, and the vehicle can operate normally. Torque is a special type of moment that causes an object to rotate. Engine torque refers to the moment output from the crankshaft end of the engine. Under fixed power conditions, it is inversely proportional to the engine speed—the faster the speed, the smaller the torque, and vice versa. It reflects the vehicle's load capacity within a certain range. External torque is called torque or external couple moment, while internal torque is called internal couple moment or torque. Any brand of tire will have a wear indicator at the bottom of the tread grooves. Generally, the wear indicator height for passenger car tires is 1.6 millimeters (this height is also the legally mandated minimum groove depth), while for heavy-duty tires, it is 2.4 millimeters. During daily vehicle use, tires may be punctured by foreign objects, leading to damage. Tire damage includes tread cracks, tread bulges, missing tread rubber, severe sidewall wear, and repeated punctures by foreign objects. Especially with bulges, there is a constant risk of tire blowout. If tire damage is detected, the owner should promptly take the vehicle to a professional tire shop for inspection and replacement if necessary. The typical lifespan of a tire is around 5 years. Beyond this period, the tire begins to age. The main signs of tire aging are surface hardening followed by cracking. Aged tires lose their elasticity, and continued use can lead to tread deformation, increasing the risk of a blowout.
