When choosing an aftermarket wheel, you need to consider several different factors for fitment.PCD, Height, Width, Offset and Center Bore.Ideally you want a wheel with the same PCD. (Juke is 5x114.3 also known as 5x114)PCD = Pitch Circle DiameterET = OffsetCB = Center BoreThe letter (J) refers to width.For example: PCD 5x114.3 18x7.5j ET30 Meaning 5 lugholes are situated over a 114.3mm diameter circle, 18in height, 7.5in width, 30mm OffsetOffset is the location of the hub mounting surface, this will vary between different wheels. Offset is calculated by the distance the mounting surface sits from the center line of a wheels side profile.Center Bore is the diameter of the hole in the center of the wheel. It is measured at the rear of the wheel and is the hole that locates to the hub on the vehicle.Example of standard to aftermarket upgraded wheel:Standard Wheel: 17x7j ET45Aftermarket Wheel 17x8j ET38The aftermarket wheel is 1in wider overall or 1/2 wider either side of the center line.1 inch = 25.4mm1/2 in = 12.7mm1/4 in = 6.35mmTherfore the aftermarket wheel as shown above would have an additional 12.7mm poke either side of a standard wheel if the offset were the same. (ET45)The original offset is ET45 or 45mm, aftermarket is ET38 or 38mmTherefore the aftermarket wheel sits 7mm further out than standard on basis that 45-38 = 7You then need to combine the two... Width and Offset.12.7mm poke due to additional Width.7mm poke due to Offset.12.7mm + 7mm = 19.7mm extra poke over standard.I hope this is of benefit to some members but feel free to contact me for further help for wheel/tyre choice.
