Which Direction to Loosen Car Tire Bolts?

[LaLuke]

For some passenger cars, tightening is clockwise, while loosening is counterclockwise. However, for large trucks, the direction of tire bolts varies: tightening is in the direction of the vehicle's forward rolling, while loosening is in the reverse direction. Below are relevant introductions: 1. Methods to deal with overly tight bolts: If you find the tire bolts too tight to loosen, the most straightforward solution is to ask someone for help. Alternatively, you can pour a lubricating solvent like diesel on the bolts. You can also appropriately use your foot to increase the tightening force on the nut, but avoid random kicking to prevent direct damage to the nut or bolt. This could also cause the wrench to suddenly pop out, posing a safety hazard. 2. Correct steps for changing a tire: (1) First, park the car properly and place a safety warning triangle 50-150 meters behind the vehicle. Loosen all the bolts of the tire that needs to be changed, but note that you must use the diagonal method to loosen them one by one. Loosen each bolt a few turns before moving to the next, and do not fully loosen one bolt at a time. Repeat this process until all the bolts are loosened to avoid deformation due to uneven force distribution. (2) Then, align the jack with the support point under the car and raise it. Once the tire is completely off the ground, you can remove it. (3) Finally, install the spare tire. After placing the spare tire, screw in the bolts, again using the diagonal method, but do not tighten them fully—just secure them in place. Once the car is lowered, tighten all the bolts completely to finish the tire installation.
