Offset
Posted Image
The offset indicates the distance from the center of the rim to the attaching disk part (unit:m/m). As seen in the attached drawing, the offset is indicated by "+" when the fitting surface extends beyond the central line of the rim and "-" when it is falls within. Caution is required to prevent the tire from coming into contact with the fender of the vehicle or the brake caliper if the offsets are very different.

P.C.D.
Posted Image
The number of bolts used to install a wheel varies from 4 to 6 depending on the vehicle model (except for some vehicle type), thus the wheel to be installed should also possess the same number of hub bolt holes. P.C.D. stands for pitch circle diameter, and indicates the diameter of the circle in mm connecting the center of each hub bolt. Since the P.C.D. also varies according to the vehicle model, make sure a suitable one is selected.

Clearance
Posted Image
Fender clearance indicates the marginal space between the tire and the fender or body of the vehicle. Inner clearance indicates the distance between the tire and wheel and the body part which is positioned closest to the tire and wheel. Dimensions for both right and left clearance should be measured on a level surface, and the smaller value is then considered as the inner clearance.

Tyre Size
Posted Image
1-Tire width (mm or inch)
2-Aspect ratio
3-Radial construction
4-Rim diameter
5-Load index
6-Speed symbol
7-Tire outer diameter (inch)
8-Ply rating

Simo, when you find the wheels you want, tell the fella u want the wheels in what ever size and width, then tell them u want a PCD of 4x100 and an offset of +45 or +42. Simple.

Offset is the distance fromthe centre of the rim, to where the stud holes are. its a + offset when the studs are closer to the outside of the wheel, and a - offset when the stud holes are closer to the inside of the wheel.

Basically, the idea behind it is to transplant the weight of the vehicle evenly down the shocks and into the wheels. If you change the centre line, the car wont be as balanced. So you want to stay as close as possible to the standard offset, or if going wider wheels ie 17x7 as opposed to 16x6.5 (or whatever the standard wheels are) get a slightly smaller offset.

Hence, +45 or +42 are your best bet cob.
