What Are Some Chevy Rim Bolt Patterns?
The conventional rim bolt patterns on Chevrolet vehicles include four-lug, five-lug, six-lug and eight-lug holes. The bolt pattern, also known as a bolt circle, is a diameter of an imaginary circle formed by the centers of the wheel lugs.
The tire pattern contains two numbers, the first of which indicates the number of bolt holes found on the rim while the second gives the diameter of the circle formed by the lug holes. A bolt pattern of 5 by 5 inches represents a five-lug pattern on a circle measuring 5 inches in diameter. Some diameters are indicated in millimeters. Some of the rim patterns found on Chevrolet vehicles include 5 by 5 inches, 6 by 5.5 inches and 8 by 6.5 inches.
Determining the measurements of even-numbered bold patterns involves measuring the distance from the center of one bolt hole to the center of bolt hole directly across from it. A specialty tool, bolt pattern gauge is required to obtain precise measurements in a five-lug wheel arrangement.
Models with the four-lug patterns include the Chevrolet Nova, Cobalt LT/LS and Aveo, while the Beretta, Camaro, Caprice and Cavalier have a five-lug configuration. Models that feature six-lug configurations include the Colorado, Blazer/Jimmy C1500 and C1500 pickup. The eight-lug pattern is typical on pickups such as the C2500 and C3500.
