Dodge Ram 1500 Bolt Pattern [1994 to 2023]

Knowing your vehicle’s bolt or lug pattern is a must if you want to rotate or replace your car wheel and ensure a perfect fit. So, what’s the most recent Ram 1500 bolt pattern? As of 2023, the bolt pattern on a Ram 1500 is 6 x 5.5 inches or 6 x 139.7 millimeters. This means the wheels of a 2022 Ram 1500 are attached to its hub using six bolts, and each bolt is placed 5.5 inches or 139.7 millimeters apart in a circle.

What about the older models? If you own a Ram 1500, you might know that the bolt pattern on these trucks varies depending on the manufacturing year and model number. Hence, the wheel size of a 1994 Ram 1500 is different from that of a 2022 Ram 1500.

Want to know how does the bolt pattern matter? Which factors should you consider for precise wheel fitment? Let’s dive deeper into the details and answer all your questions.

Key Takeaways:

  • All Ram 1500 trucks manufactured from 1994 to 2010 have a bolt pattern of 5 x 5.5 inches/139.7mm
  • Generation V Ram 1500 trucks manufactured from 2019 to 2022 feature a 6 x 5.5 inches/139.7mm bolt pattern
  • To measure the bolt pattern of your Ram 1500, you need to count the number of lugs on the hub and measure the diameter of the imaginary circle the lugs form

What Is the Bolt Pattern On A Ram 1500?

First things first, you need to know what exactly is the bolt pattern and how it is expressed. At the center of your car wheel, several lug or bolt patterns are placed at equal distances from each other, forming a circle.

The measurement of this imaginary circle and the number of lugs or bolts is called the bolt pattern. It is also referred to as the lug pattern, bolt circle, and Pitch Circle Diameter (PCD).

Typically, the bolt pattern is mentioned as PCD on an owner’s manual or the official site of the manufacturer.

On a Ram 1500, bolt patterns can be 3-, 4-, 5-, or 6-bolt holes. The diameter of the imaginary pitch circle is either shown in standard US units ‘inch’ or metric units ‘millimeters’.

  • Bolt Pattern Example:

If the mentioned PCD value for a vehicle is 4 x 3.94 inches or 4 x 100 millimeters, it simply means that the wheel has 4 bolts/lugs or bolt/lug holes that form a 3.94-inch or 100mm circle on the rim center.

Why Does Lug Pattern Matter?

Knowing the lug pattern is a must as it helps you to choose the right wheel that fits snugly on your vehicle. The lug nuts should perfectly match the diameter of the bolt holes of your vehicle. The wheel is locked in place by the lug nuts.

If you don’t know the lug pattern of your vehicle, you might purchase the wrong wheel that doesn’t offer a perfect fit. While driving with such wheels, the lugs might come loose and the wheel will slip as a result.

This leads to unwanted catastrophes on the road causing damage to the driver, passengers, and other car owners driving on the road. So, check out the lug pattern for your vehicle before you purchase new wheels.

How to Measure the Bolt Pattern Of A Ram 1500?

As mentioned, you only need two measurements to know the exact bolt pattern of your Ram 1500. First, you have to count the number of bolts/lugs on your truck wheel. Secondly, measure the diameter of the imaginary circle running across the bolt center.

Typically, you can refer to your owner’s manual to know the accurate bolt pattern for your specific Ram 1500. However, in some cases, the manual might not be in your hands.

So, it’s always a good idea to learn how to measure your truck’s bolt pattern, especially because it’s an incredibly easy method.

Here’s a step-by-step process of measuring a bolt pattern-

Step One: Take Safety Measures

Before anything else, you must ensure your safety by securing the vehicle. Place your Ram 1500 on a flat surface where you can easily lift it with a jack stand if needed.

Now, make sure the vehicle is completely stable and won’t move while you’re working. For this, you can use the emergency brake of your truck and keep it fixed.

Step Two: Gather Necessary Tools

Thankfully, you won’t need any fancy tool to take the measurements. You’ll only need the following tools for this job:

  • Screwdriver
  • Tape measure
  • Bolt circle template (optional)
  • Tire iron (optional)

Got all of them? Let’s proceed to the next step then.

Step Three: Take Off the Hubcap

Your Ram 1500 might or might not have a hubcap depending on the manufacturing year. If there’s a hub cap on the wheel, you must remove it to expose the lug nuts.

For this, get a screwdriver and insert it into the hub and rim area. Choose only one wheel to work with, as all the wheels are on a Ram 1500. Apply gentle pressure on the screwdriver, and the hubcap should easily come off.

Step Four: Count the Lug Nuts

Now that the center of the wheel is exposed, you can easily locate the lug nuts. As we have seen above, all Ram 150p produced between the years 1994 and 2022 have either 5 or 6-lug nuts.

Count and note the number of lug nuts and proceed to the next step.

Step Five: Measuring the Pitch Circle

Now, we need to measure the diameter of the pitch circle formed by the lug nuts. Here, the methods differ for an odd and even number of lug nuts.

  • If your vehicle has an even number of lug nuts (4, 6, or 8), Use a tape measure to gauge the distance from the center of one lug to another placed across from one another. Here, you need to hold the tape measure parallel.
  • For an odd number of lug nuts, you need to measure the distance between the top of one lug nut and the center of another lug nut placed across from it.

Remember, this method might not be completely accurate and only gives you an estimate of the circle diameter.

Step Six: Measure with Bolt Circle Template

For precise bolt pattern measurement, you’ll need a bolt circle template. Only a few dollars and a visit to the auto supply store will get you this highly convenient tool.

The template has a number of holes and size markings. To use it, you need to take off the lug nuts and expose the bolts. You can use a tire iron to easily remove the lugs.

When you’re done, place the template on the wheel studs and note down the measurement using the size markings.

Step Seven: Final Evaluation

At this point, you have all the necessary numbers to evaluate the bolt pattern. Here is how it’s expressed:

Number of bolts/lug nuts x pitch circle diameter.

So, if your truck wheel has five lug nuts and the circle diameter is 5.5 inches or 139.7mm according to your measurement, your vehicle’s bolt pattern is 5 x 5.5 inches/139.7mm.

Tightening Lug Nuts

When your vehicle’s lug nuts come loose, you’ll hear a loud knocking sound coming from your wheels while driving. In such situations, you must pull over the vehicle immediately and tighten the wheel nuts.

Experts recommend that you check the wheel nuts’ fit every 30 miles or 48 kilometers. If your vehicle is subjected to heavy driving or regular towing, the nuts will become loose more often.

No need to worry about that, though, as tightening the nuts is easy, and you’ll only need a torque wrench for this job. Here is a step-by-step process for tightening the wheel nuts of your Ram 1500:

Step One: Get Your Truck Ready

You don’t need to jack up your vehicle while tightening the lug nuts. In fact, using a jack stand will rather be a hassle as the wheels keep turning in the air.

So, place your Ram 1500 on a flat surface and put it into first gear. Now, pull the handbrake and proceed to the next step.

Step Two: Prepare the Tool

This step is important because the recent Ram 1500 trucks require specific torque to seal the lug nuts accurately. If you don’t use the right torque wrench, the fit might be too loose or too tight.

As a result, the nuts will easily come loose or get stripped while driving. So, refer to your Ram 1500 owner’s manual first to know the torque value for your vehicle model.

The most recent trucks need to be tightened at 130 lb-ft. Once you have learned the torque value, set it on the torque wrench and release the wrench lever.

You’ll hear a small click in the tool when the wrench is ready.

Step Three: Tighten the Bolts

Now, rotate the torque wrench in a clockwise direction to tighten the bolts on your Ram 1500 following the criss-cross pattern. To prevent slacking of the spring, loosen the torque wrench halfway through the process.

Otherwise, the torque settings will be incorrect, and the wrench won’t reach the required torque value.

When you’re done, check the fit and drive about one mile or so to see if the wheels are still making weird noises.


What is the most common bolt pattern on Ram 1500 trucks?

A 5-lug bolt pattern is most common for Ram 1500 trucks. All the Ram 1500 models manufactured from 1994 to 2018 (generation II-IV) have a bolt pattern of 5 x 5.5 inches.

In these trucks, the wheels are fastened to the vehicle using 5 lug nuts placed in a star-like pattern. Not all 5-lug bolt patterns are the same, and it vary depending on the vehicle brand and production year.

Does tire bolt pattern matter buying?

Yes, you must get the bolt pattern right to ensure maximum safety for you and your vehicle. The bolt pattern is specific to the vehicle model and manufacturing year.

Hence, you can’t choose wheels that don’t match the bolt pattern of your vehicle, no matter how close the size is and how snug it feels.

If you get the bolt pattern size wrong, the wheel won’t fit correctly to the vehicle as the lug bolts won’t sit in the lug holes. As a result, the wheels might come loose while driving and cause unwanted mishaps.

Can the bolt pattern be changed?

Yes, the bolt pattern of your vehicle can be changed with the help of experts. If you want to perfectly fit a particular type of wheel to your vehicle that doesn’t match the bolt pattern, you can simply use a hub or PCD adapter.

Although the tool is expensive, this is the easiest way to change the bolt pattern of any vehicle. However, your vehicle wheels must be a high offset as the PCD adapter takes about 20mm of space.

Another way of changing the bolt pattern is to re-drill holes or fill the old ones. However, this method should only be done by experienced mechanics as it might ruin your vehicle if something goes wrong.

Is 5×5 and 5×139 the same?

No, 5×5 is the bolt pattern of a vehicle expressed in inches whereas 5×139 is in millimetres. When we convert 5×5″ into millimeters, it equals 5x127mm, not 5x139mm. The customary equivalent of 5x139mm is 5×5.5 inches.

When did Ram 1500 go to 6 lugs?

Ram 1500 went to a 6-lug pattern at the year 2019. Generation V Ram 1500s manufactured from 2019 to 2023 have a bolt pattern of 6×5.5″ or 6×139.7mm.

Why do trucks have 6 lugs?

Trucks have higher load capacity than regular passenger vehicles. The bolt pattern needs to be changed to support the increased load. Instead of changing the bolt diameter, increasing the number of bolts is cheaper. So, trucks have 6 lugs instead of 5.

What rims will fit a Ram 1500?

Some Ram 1500s like Sport and Laramie can fit 20-inch rims. The remaining ones such as TRX/TRX and ST 4 trims can accommodate up to 17-inch rims. Refer to your owner’s manual to see which rim fits your Ram 1500 model.

Are all 5 lug rims universal?

No, 5-lug rims aren’t universal. Although most passenger cars and light-duty trucks have 5-lug rims, the actual size remains different for various manufacturers.

Wrapping Up!

So that was all about the Ram 1500 bolt pattern. You can visit the official website of Ram Trucks to see the specifications of your Ram 1500 and find out its lug pattern or PCD. Typically, the bolt pattern on a Ram 1500 is either 5 x 5.5 inches or 6 x 5.5 inches. With this measurement, you can easily find the right wheel for your Ram 1500 and choose the correct tools whenever any type of repair is needed.
