**How To Measure Tire Rim Bolt Pattern**. 5×114.3 mm is also referred to as 5×4.5). A bolt circle of 5×114.3 mm would indicate a 5 lug pattern on a circle with a diameter of 114.3mm (or 4.5).

Below we illustrate how to measure your wheels bolt pattern. Bolt circles are measured in both inches and millimeters, therefore you may hear a bolt pattern referred to as both (i.e.

Bolt pattern or bolt circle is the diameter of an imaginary circle formed by the centers of the wheel lugs. Common bolt patterns have 4, 5, 6, or 8 lug holes, while less common have 3, 7, or 10 lug bolt patterns.

### How To Measure Tire Rim Bolt Pattern

**First, measure the center to center distance between two studs that are across the hub from each other.**For a 4 lug wheel, measure center to center of two holes directly across from each other.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.

**If the trailer wheel has an even number of lugs, measure from the center of one bolt to the center of the bolt directly opposite using a tape measure or ruler.**If there are 5 studs, multiply the measurement by 1.05 to get the bolt pattern diameter.If there are 7 studs, multiply the measurement by 1.03.If you have 4 bolts on a 100mm bcd, it’s 4 x 100mm.

**If you were to draw a circle through all of the lug holes in your wheel, the diameter of that circle, is your bolt pattern.**In a decimal that’s 6.125.Interchangeable wheel / bolt pattern chart for cars, trucks, vans, suvs, motorhomes, rvs, atvs, utvs and trailersIt basically goes the same as the 4 bolt rim.

**It’s really very simple to measure your wheels bolt patter with a tape measure or ruler.**Luckily, it’s actually really easy to measure a bolt pattern.Measure from the middle of one stud to the outside of the second stud (skipping a stud).Measure using the metric side of the ruler, in millimeters.

**Multiplied by 25.4 that equals 155.575.**Next, you’ll measure how many inches apart the bolt holes are.Once you know the bcd, the second step is simple—add the number of bolts.One other trick is to to use a straight edge block across the back of two of the lugs a and then set the ruler on that and measure up to the center of the bolt like in the picture.

**Or the way i prefer is to measure from the center of a bolt hole to the outside edge of either of the bolt holes furthest from.**Other common bolt patterns are 5×4.75 and 5×5.Put those two numbers together, and bam!So if you see 4 1/2 inches, you have a 5 on 4 1/2 ( also 5×4.5 and 5×114.3) bolt pattern.

**So if your bcd is 4.5 inches and you have 5 lug studs, the bolt pattern is 5 x 4.5”.**So, you have to measure from the center of one hole and end up to the center of the opposite hole.The diagram above should make it clear.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.

**The number you see will be the actual measurement of the bolt pattern.**These two steps together will give you your bolt hole pattern.This is sometimes called the ‘bolt circle’ or some such thing.This technique works for trailer wheels as well as automotive and truck wheels.

**To find your bolt pattern, measure the distance as accurately as possible and then find the corresponding bolt pattern in the conversion table below.**To measure 5 lug pattern wheels, hold the end of the ruler or tape measure to the center of one bolt.To measure a tractor’s rims, measure the width of the rim from the inside bead sets, then measure from the outside of the rim from edge to edge.To measure the rim bolt pattern on a wheel with 5 bolt holes, hold the tape measure on the edge of a bolt hole and measure across to the center of the 2nd hole.

**To measure your bolt pattern, establish an imaginary circle that passes through the middle of each stud and.**Typically this will be 4, 5, 6, or 8.Wheel bolt pattern is the measured diameter of an imaginary circle formed by the centers of the wheel studs or bolt holes.When it comes to 6 bolt rim, the measurement process is also easy.

**When you are thinking about how to measure tractor tires and rims, it is also important to check inside the bead fledge because many manufacturers indicate the rim size there.**You can also determine your 5 bolt pattern by measuring the distance between the center of one bolt hole, to the center of the bolt hole next to it.You can choose basically any hole to start with, but, you have to.You get a measurement of 6 1/8″.

**You will need to figure out the bolt pattern of your hubs, which may be found online or by measuring.**You’ve got an accurate measurement of your bolt pattern.
