Any BMW car owner can find the precise torque of the BMW lug bolts in the manufacturer`s manual or on official Internet sources. The recommended torque spec for BMW lug bolts is 140 NM / 103 ft-lbs (always inquire with a tire expert before operating). To torque the BMW lug bolts well, it is highly recommended to use a torque wrench instead of an impact wrench. Never trust an impact gun can settle everything down. Because it is hard for an impact gun to ensure each wheel stud is evenly tightened with the same torque.
Set the torque wrench to the manufacturer’s recommended value. Then simply turn the wrench handle until it reaches the torque mark. Tighten the wheel nuts a quarter turn at a time following the crisscross sequence (in a “star” pattern). This ensures that all the wheel bolts are forced evenly. When the BMW lug bolts are properly torqued down, you will feel a click around the head of the wrench.
What BMW Lug Bolts Are Good?
As a professional wheel accessories manufacturer, BONOSS provides a full line of BMW wheel bolts to fit your aftermarket wheels and spacers, lengths from 27mm to 75mm. They are made to the ISO Grade 12.9 standards: the tensile strength is over 1,282 MPa. It makes sense that stronger bolts are safer, because the higher strength the bolt is, the more force it can withstand more force before breaking.
In addition, the seat parts of BONOSS forged ISO grade 12.9 BMW wheel bolts are floating styles. This makes it convenient to change the seat types to fit various wheels. Compared to the integral-seat wheel bolts, they are more flexible. By simply changing the seat washer, you can transform a conical seat into a ball seat. Since the floating seats are not fixed, these BMW wheel bolts can effectively prevent your valuable wheels from being scratched by the bolts.
