When mounting wheels on a vehicle, tighten the wheel lug nuts:

Tightening lug nuts should bring the wheel to the hub evenly and to the exact clamping force specified by the manufacturer. Doing this gradually in a defined sequence—often described as a star or crisscross pattern—pulls the wheel evenly toward the hub so all studs engage at the same rate. This prevents one side from seating first, which could warp the wheel or cause the lug to loosen later. Reaching the final torque in steps ensures accurate, uniform loading across all lug nuts. Tightening all at once or relying on finger-tight could lead to uneven seating or under- or over-torquing individual bolts.
