The Chevy Astro van is a popular vehicle used to transport people and cargo. Understanding your vehicle’s specifications is crucial to ensure proper maintenance and modification. One of the critical specifications to know is the bolt pattern.

What is a Bolt Pattern?
A bolt pattern is a set of numbers that describes the location and number of bolt holes in a vehicle’s wheel. The bolt pattern is determined by the number of bolt holes and the distance between them. For example, a 5×120 bolt pattern means there are five bolt holes, and the diameter of the circle that passes through the center of each bolt hole is 120mm.
