Wheel Bolt Pattern Guide The easiest way to estimate the 5 lug bolt pattern, is to measure from the back of a hole to the center of the second hole. For a 4 lug wheel, measure center to center of two holes directly across from each other. Measuring a 6 bolt wheel requires you to measure center to center of two holes directly across from each other. First, count the number of bolts on the wheel well, then measure the diameter of a circle that runs through the center of each bolt. Put those two numbers together, and bam! You've got an accurate measurement of your bolt pattern. Part 1 Counting the Bolts Download Article 1 Park the vehicle and turn off the engine.
To find your bolt pattern, measure the distance as accurately as possible and then find the corresponding bolt pattern in the conversion table below. For example, if you have a 5 lug wheel and your measurement is 5″ then your bolt pattern is 5 x 5″ (5 x 127mm). how to measure bolt pattern Bolt Pattern Conversion Chart Step 4: Discover the Bolt Pattern Now that you have measured the amount C, you have to think about the P.C.D. It refers to Pitch Circle Diameter. It is necessary when it comes to measuring the 4 lug or 6 lug vehicles. The P.C.D or the bolt pattern diameter here is the distance you have just measured.
It can appear in either inches or millimeters, so be sure you know which one you're looking at. Bolt patterns in 4- 6- and 8-lug can be measured by going from the center of a stud to the center of the stud directly across from it. A 5-lug bolt pattern is a little more difficult to measure, but you can easily do that by following the diagram below.
To determine the bolt pattern on a 5 lug wheel, measure from the center of a wheel stud to the outer edge of the stud furthest away from it. Take a look at our diagram for an illustration of how it is measured. Large Ford Pattern | 5 on 5.5 inches Early Ford passenger cars use a 5x5.5-inch bolt pattern, which can also be listed as 5x5-1/2 inches.
Given in a two number system, a bolt pattern, also known as the lug pattern, 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 the wheel has. The second number is the diameter of the imaginary circle around the holes.
(4, 6, or 8 Holes) To measure between the holes on a wheel with an even number of holes, simply measure from the center of one bolt hole to the center of its opposite to determine the diameter of the lug pattern. Bolt Patterns for Wheels with 4 Bolt Holes Common bolt patterns for wheels with 4 bolt holes are: 4 on 4 4 on 9.44
This video will show you how to properly measure a bolt pattern on a 5-lug wheel.www.coyswheel.com (801) 426-4736
Before worrying about equations, remember, the easiest way to get BCD for a bolt pattern with even numbers of bolts is direct measurement. Strait across from one bolt or hole, to the opposite bolt or hole on the other side of the hub. There are only a few standard patterns, so you don't have to be super exact in measuring.
Use a ruler or a tape measure, measure the distance from the middle of one bolt hole, skip one bolt hole in any direction, and then measure to the farthest edge of that bolt hole. The number you get is the bolt pattern of wheels with odd numbers like 3 and 5. To avoid any issues at the wheel fitment shop, make sure you measure the rear and.
To measure a 5-lug rim, place the hook of your measuring tape in the middle of a bolt. Then, choose 1 of the 2 bolts on the opposite side. Pull your measuring tape to the outside edge to measure the bolt pattern.  It doesn't matter which of the bolts on the opposite side you choose to use. Method 4 Offset and Backspacing Download Article 1
There are lots of ways to figure this out, but how can it be done accurately with what you have around the house? Easy, we show you in this video of our part.
Check out Discount Tire's video guide on how to measure a wheel bolt pattern. This guide also covers measurements and explains the difference between single and dual-drill bolt patterns. For more.
The bolt pattern consists of two numbers and looks like this (5x4.50) - 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).
The first number—five—refers to the number of lugs present, while the second number—four and a half—refers to the diameter of the bolt circle in inches. There is one more thing to be aware of, and that's the difference between four, five, six, and eight-bolt wheels.
For vehicles that use 4, 6, or 8 lugs, the simplest way to find its inner diameter is to measure the distance between holes directly across from one another. Using measuring tape or a long ruler, calculate the space from the center of one bolt-hole to the center of the one opposite it. This will give you the most accurate measurement.
The 6 X 5.5 Bolt Pattern or Pitch Circle Diameter (PCD) is made up of the stud count (6) and the bolt circle measurement (5.5), the notional circle determined by the center position of the studs. How To Measure 6 Lug Bolt Patterns. Measure 6 lug wheel bolt patterns from center to center distance between two studs that are across the hub from.
This is a video demonstrating how to measure the bolt pattern on an ATV or UTV.
When measuring to determine the bolt pattern of a wheel with an odd number of lugs, like a 5 lug wheel, you are basically measuring the diameter of a circle that would run through the center of each lug hole. If you are measuring the wheel the easiest way is to measure the distance between the center of one lug hole to the center of the lug.
