Common wheel bolt patterns are four on 3.94 inches, four on 4.5 inches, five on 4.5 inches and five on 5 inches, representing the number of bolt holes in a wheel and the diameter of a circle drawn through the bolts. Four-bolt and five-bolt patterns are typical for passenger cars while six-, seven- and eight-bolt patterns are used for sports utility vehicles and trucks.
Bolt patterns are often available by vehicle make, model and year from sources such as DiscountTire.com and DiscountedWheelWarehouse.com. Some instances require measurements.
The four on 3.94-inch bolt pattern, also expressed as four on 100 millimeters, is found on Chevrolets, Dodges, Hondas, Toyotas and Volkswagens. The four on 4.5-inch pattern is on Dodges, Hondas and Infinities. Determining the bolt circle diameter of a four-bolt wheel involves measuring the distance from the center of any two holes opposite each other.
The five on 4.5-inch bolt pattern is on Acuras, Chryslers, Fords and Mazdas. The five on 5-inch bolts are on Chevrolets. The bolt circle diameter of a five-bolt pattern is harder to determine, being the distance from the center of one hole to the outside edge of a second hole that is two places away from the first. Some patterns are almost identical, requiring precise measurements often best taken using a bolt pattern gauge. A wheel with a slightly mismatched pattern may lead to bent lugs and wheel vibrations.
