It refers to the size of
the center hole of the hub. Although you can mount the positioner, but

2, the pitch circle diameter (PCD)
For example, the pitch
circle diameter of 4 * 100mm wheels, which has representatives of four
bolts, they form a circular diameter of 100mm. This value should be
consistent with the original.
3, offset (OFFSET)
Acronym ET value, the
value is positive, indicating that outside the central plane, and vice
versa within the central plane of the hub fixing surface. Cars are
generally offset value is positive, the tracking of the impact of the
value of the car with the stability and cornering a major, original
determination will be good, non-special needs can not be changed.
4, diameter and width
[Transfer from Jagged Community http://www.tiexue.net/]
It determines the size of
the diameter of the rim. Since the car speedometer readings are based
on the wheel speed measurement, wheel diameter over the General Assembly
cause speedometer readings small, unconsciously, you're speeding.
Oversized wheel diameter will be scraped into the wheel arches and
fenders. Thus, the hub is better than the original upgrade to a large 1
inch, no more than 2 inches, but also with the eggshell to ensure that
the size and upgrade the whole of the front wheels almost. Width on the
upgraded selection of the tire, the tire is too wide will reduce the
initial speed and more fuel. Corresponding to the common values of:
185mm wide tire corresponding to 5-inch wide rim; 195mm corresponding to
6 inches; 205mm corresponding to 6.5 inch; 215 corresponds to 7 inches.
Macao and Thailand the hub of everything.
