PCD stands for'Pitch Circle Diameter' and is usually expressed in millimetres, (inches may also be used). For a 4 or 6 bolt fitment this measurement is the distance between the centre of two diametrically opposite bolt holes. For 5 bolt fitments measuring the diameter of an imaginary circle running through the centre of each bolt hole. The offset of a vehicle's wheels is the distance between the centerline of the wheel and the plane of the hub-mounting surface. This is typically expressed in millimetres and can be either positive / negative. The offset plays a significant role in the vehicle's suspension geometry as well as dictating the distance between the tyre and suspension.
Not to mention the visual gap between the wheel and the vehicle bodywork. The stud / bolt pattern refers to the number of studs, (or lugs) the wheel bolts onto, and the imaginary circle the studs form. Most vehicles have either 4, 5 or 6 bolt patterns. The centre bore (or hub diameter) of a rim refers to the size of the centre hole in the middle of the wheel. This correlates to the diameter of the hub centre bore and is usually expressed in millimetres.
Hub centric refers to the the the point at which the primary load of the vehicle is placed. Hub centric wheel spacers ensure less load is placed on wheel bearings and other suspension components by keeping this load on the vehicle hub. The alternative is to us'lug centric' spacers which rely on the wheel studs to centre the wheel on the hub. Good practice for fitting spacers of thicknesses greater than 10mm is to use hub centric wheel spacers.We are a UK based company that offer high quality performance vehicle parts and accessories at competitive prices.
