What is a Valor Offroad Dual-Drill UTV Wheel? A dual drilled wheel is a wheel that is drilled with two sets of bolt holes. With this additional set of holes, dual drill wheels can accept two different bolt patterns. On all dual-drill wheels, the larger hub bore of the two bolt patterns is used to ensure proper fitment.
HOW TO MEASURE A BOLT PATTERN?
The bolt pattern, also known as the lug pattern or PCD (Pitch Circle Diameter), is the measurement of an imaginary circle formed by the lug holes at the center of your wheel. The first number indicates how many bolt holes are in the wheel. The second number is the diameter of the imaginary circle around the holes. For example, a wheel with a 4x156 bolt pattern (also shown as 4/156), has 5 lug holes equally spaced around a 156mm diameter circle.
Typically, larger vehicles have more lugs (think HD trucks with an 8-lug bolt patterns), while smaller vehicles have fewer connection points. Knowing your bolt pattern is a good idea, no matter what make/model you decided on.
A dual bolt pattern drilled wheel is a wheel that is drilled with two different sets of bolt holes. With this additional set of holes, dual-drill wheels can accept two different bolt patterns. In Valor wheels example below, the dual drilled wheel has both 4x156 (ex. Polaris RZR) and 4x137(ex. CanAm X3). On all dual-drill wheels, the larger hub bore of the two bolt patterns is used to ensure proper fitment.
