WHEEL INSTALL: TORQUE WRENCHES

WHY EVERYONE SHOULD TORQUE
Every vehicle has a particular amount of torque, or force, to tighten a lug or bolt when installing a wheel on a car. These numbers are recommended by the manufacturer and can easily be found in any vehicles’ owner’s manual. It is very important to tighten lugs or bolts correctly on the car. If the wheel is not tight enough it will cause vibrations and wobbling of the wheel. On the other hand, if the wheel lug or bolt is too tight, this will but excessive force on the brake assembly and may cause brake damage.

Although it is not required, we strongly recommend that you purchase a high quality torque wrench. The torque wrench will provide you with accuracy up to two-percent clockwise and four-percent counterclockwise. The digital display will show you the torque ranges between five and one hundred ft. and lbs. and will give you the choice of three units of measure between lb., ft. lb., and Nm.

TORQUE TIPS
It is recommended that you re-torque your tires after you break them in, this period is the first 50 to 100 miles they are driven on. During that period the tires may compress slightly allowing the lugs to lose some torque. Below are the usual torque requirements depending on the size of the hardware. The hardware is simply the lug or the bolt for the wheel. And the size is imprinted on the metal of the hardware.
