Why is it important to hand tighten the lug nuts?

Hand tightening the lug nuts is crucial because it ensures a snug fit before lowering the vehicle. This step helps to align the wheel properly on the hub and allows for any slight adjustments that may be necessary before applying final torque with a wrench. When lug nuts are hand tightened, it reduces the risk of cross-threading and provides an opportunity to detect any misalignment quickly.

Additionally, this practice enhances safety by ensuring that the lug nuts are evenly distributed, reducing the likelihood of wheel detachment once the vehicle is back on the ground. It is an essential step in the tire changing process that should not be overlooked, as it contributes to the overall integrity of the wheel assembly.
