A 5 lug bolt pattern refers to wheels that have five holes for bolts. The specific arrangement and spacing of these holes determine compatibility with various vehicles. Common 5 lug bolt patterns include: 5×100 5×108 (or 5×4.25 in inches) 5×112 5×114.3 (or 5×4.5 in inches) – one of the most prevalent 5×120

The bolt pattern consists of two numbers and looks like this (5×4.50) – the first number in this example “5” indicates how many bolt holes or studs are on the vehicle, the other number “4.50” describes the diameter of the circle formed by those “5” holes or studs in either inch or millimeter units (4.50 is inches).

A bolt pattern is the number of lug holes in a wheel and the distance between them. Bolt patterns are usually expressed in two numbers: the number of lugs on the wheel and the distance between each lug in inches. For example, a 5x100 bolt pattern means the wheel has five lug holes, and the distance between each lug is 100 millimeters.

The 5 on 4-1/2 inch bolt pattern is the most popular 5 bolt lug pattern found on trailer wheels. There's an easy way to measure and be sure though. You need to measure from the center of one lug to the center of the lug nearest to it. If the distance is: 2-5/8" - the bolt pattern is 5 on 4-1/2 2-3/4" - the bolt pattern is 5 on 4-3/4
