b'Technical InformationHUB FITTING WHEELSHub fitting wheels have a bore and a number of stud holes to suit the hub to which it is being attached. When fitting the wheels to the hub, it is very important to tighten at the correct torque in order to prevent nuts from working loose. It is also important to check after a short period of use and on a regular basis thereafter. The correct nut must be used to suit the wheel seating eg. conical or spherical.GA=Bore (mm)B=Pitch circle Diameter (PCD) mmBD =Back depth (mm)F B A ET =Offset (mm)E=stud hole diameter (mm)F=Rim diameter (Inches)G=Rim width (Inches)ET ECOMMON STUD PATTERNSNO.
