The bolt pattern is also known as the lug pattern, as it measures the imaginary circle formed by your wheel’s lug nut holes. In order to find the perfect wheels for your vehicle, you must know the bolt pattern.
It is common for older models of Acura and Hondas to have a 4×3.94 lug pattern, while most newer models have a 5×4.5 lug pattern. So, whether you’re upgrading your tires or changing your Acura’s rims, you need to know your car’s lug pattern.
Bolt Patterns: An Overview
There are two numbers used to indicate bolt pattern measurements: the first indicates how many lug holes the wheel has. An imaginary circle’s diameter, usually measured in millimeters, is the second number.
There are usually more lugs on larger vehicles than on smaller ones. So, for example, it would have eight lug holes on a Ford F-250 truck, as opposed to four on a Kia Rio.
A five-lug pattern is most common on smaller vehicles. For both style and safety reasons, it’s crucial to understand your vehicle’s bolt pattern before ordering wheels.

Do you need help figuring out your Acura’s lug pattern? We’ve laid out Acura’s most popular models’ wheel specs below, so you don’t have to worry about anything.
For Acura’s as old as 2001 to the present, this table includes wheel size, offset, stud size, and hub/center bore measurements.

|Model||Year||O.E. Wheel Size||Bolt Pattern||Stud Size||Hub Center Bore||Offset|
|2.2/ 3.0 CL||95-98||15×6||4×114.3||12×1.5||64.1||H|
|3.2 CL V-6||99-03||15×6||5×114.3||12×1.5||64.1||H|

How To Measure Your Acura’s Lug Pattern?
You can always measure your lug pattern yourself with a ruler and some measuring tape if you can’t find your Acura in the above table:
Measure from the outside edge of one lug hole directly across from the center of another lug hole if your wheel has an odd number of lug holes.
Measure the distance from the center of one lug hole to the center of the one directly across from it if your wheel has an even number of lug holes.
For $9, you can purchase a bolt pattern gauge that will help you get precise measurements faster and more easily.
Acura Bolt Pattern Cross Reference Guide And Wheel Sizes
The majority of rims are not car specific. As a result, they can be changed from TL to another vehicle and vice versa. However, not all rims are bolt-on compatible with your TL studs.
You should consider a number of factors if you want to ensure fitment. A very important step to take is to compare the bolt pattern on your TL wheel with the bolt pattern on your intended wheel.
When it comes to selecting the right solution, you may need information about the stud or bolt pattern. Find your vehicle’s bolt pattern by selecting the make, model, and year.
An imaginary circle formed by the centers of the wheel lugs or bolt holes is called the diameter of a wheel bolt. Bolt circles, lug patterns, and lug circles are sometimes used to describe them.
Besides these names, there are a few others as well. For example, when you see a 5 by 4.5-wheel bolt, you should remember that it refers to a 5-bolt pattern with a 4.5-inch diameter.
An Explanation Of How Bolt Patterns Are Measured
If you have an even number of lugs, measure them center-to-center. If there are odd numbers of lugs, don’t do that.
Instead, measure the diameter from the center of one lug to the outer edge of the hole. If you do this diagonally across the hole, you’ll most likely get the best results.
Torque Specifications For Bolt Patterns Should Be Checked
Use a torque wrench to install your alloy wheels. For accurate specifications, consult your owner’s manual. You should recheck the torque specifications after a test drive.
As a result, you’ll successfully avoid torquing your lug nuts or bolts incorrectly. It is easy for vibrations and rigors of driving to loosen bolts and nuts, causing lots of avoidable problems. So, whenever you install new wheels, retorque the wheel lugs after driving 50 to 100 miles.
How Do I Know What Wheel Size Is Right For Me?
You can determine the ideal wheel size by taking four important measurements. You can find them here:
Bolt Pattern For The Acura TL
Calculates the diameter of an imaginary circle created by the wheel lugs or bolt holes.
Identifies the distance between your wheels inside edge and the region where the axle flange, the brake, and the hub in contact with it.
To determine the width of the rim, measure the distance between the outer lip and the bead on the inner lip.
Acura TL Rim Diameter
Take a look at the area where your tire beads are seated. The diameter of your wheel at that particular point is measured.
The Basics Of Lug Pattern Terminology
Don’t know where to begin? Do you have trouble understanding terms such as OEM and center bore?
It’s not the first time someone has been curious about lug patterns – especially if they have never done so. However, once you know their definitions, they’re not too hard to understand.
A center bore is the opening on your hub that centers your wheel. As you drive, it also reduces vibrations from your wheels. Before changing your rims, make sure you check the size of your model.
When attaching new wheels, you need to know the stud size of the fasteners. US fasteners are expressed as stud diameter x threads per inch (e.g., 1/2×20), whereas metric fasteners are expressed as stud diameter x distance between threads (e.g., 14mm x 1.5).
Using this number, you are able to determine the distance between the wheel’s center line and the hub mounting surface. Positive offsets have hub mounting surfaces more toward the front of the wheel centerline.
Negative offsets have hub mounting surfaces behind the wheel centerline. Again, look at the wheels: if they appear to be sticking out, the offset is probably negative.
The bolt pattern indicates the number and diameter of lug holes (which determines the spacing between them) along with the number and diameter of the circle formed by them. You’ll need to know this pattern to find a wheel that fits your Acura.
OEM Wheel Size
OEM wheel size is the standard or original size of the wheels your Acura came with. “OEM” stands for “Original Equipment Manufacturer.” Make sure you match the rim size when you replace the wheels.
What Is The Purpose Of Knowing Your Acura’s Lug Pattern?
The lug holes on every car’s wheel connect the rim to the hub. On your vehicle’s wheels, the lug pattern-also called a bolt pattern-measures, how many lug holes there are and their spacing.
A lug pattern consists of two numbers: one indicates the number of holes, and the other indicates the distance between each hole, determined by the diameter of the imaginary circle formed by these holes.
The Bottom Line
A 5×4.5 lug pattern indicates that the wheels have five individual lug holes arranged in a circle of four-point-five inches. The lug pattern of your Acura is important to know whether you’re replacing old tires or upgrading to something new.
