By the end, you’ll know how to keep your Ram 1500 in top shape with the perfect wheels.
Learn About Bolt Patterns?
A bolt pattern is vital for correctly fitting wheels on your vehicle. It shows how lug holes on a wheel are arranged. For example, “6×139.7mm” means there are six lugs with a Pitch Circle Diameter (PCD) of 139.7mm.
Knowing bolt patterns is key for safety and performance. The wrong bolt pattern can cause dangerous driving and wasted money on wheels that don’t fit.
Definition and Importance
The bolt pattern involves two main measurements: the number of lugs and the PCD. For lugs in even numbers, measure the PCD from one lug’s center to the opposite lug’s center.
With odd numbers, it’s from a lug’s center to the far edge of the lug across. The RAM 1500 Classic, for example, uses a 5×5.5 inch pattern, while the RAM 1500 New Body has a 6×5.5 inch pattern.
Using the wrong size can harm your vehicle’s performance and cause alignment problems.
How Bolt Patterns Affect Vehicle Performance?
Choosing the correct bolt pattern is crucial for mounting wheels and affects your vehicle’s performance, safety, and tire wear.
The wrong pattern can ruin wheel alignment, causing uneven tire wear and poor handling. The specific lug sizes for the RAM 1500, M14x1.5 and 1/2-20, match its bolt patterns for optimal performance. Knowing these details prevents costly errors and repairs.
| Truck Model | Bolt Pattern | Lug Size |
|---|---|---|
| RAM 1500 Classic | 5×5.5 inches (5×139.7mm) | M14x1.5 |
| RAM 1500 New Body | 6×5.5 inches (6×139.7mm) | M14x1.5 |
| Dodge Ram 1/2 Ton Trucks (’94 & Newer) | 6×5.5 inches (6×139.7mm) | M14x1.5 |
| Dodge Ram 1/2 Ton Trucks (’94 & Newer) | 8×6.5 inches (8×165.1mm) | M14x1.5 |
What Is The Ram 1500 Bolt Pattern?
The wheel bolt pattern of the Ram 1500 changes depending on the model year. Early models from 1994 to 2008 use a 5-lug design measured at 5×139.7mm.
The newer models, from 2009 onwards, have a 6-lug pattern measured at 6×139.7mm. It’s important to know your truck’s bolt pattern for choosing the right wheels.
The following specs are key for different Ram 1500 model years:
| Model Year | Bolt Pattern | Lug Nut Size | Center Bore | Torque Specification |

Ram 1500 Bolt Pattern Specifications By Year
The Dodge Ram 1500’s specs have changed over time, affecting its performance and how wheels fit. It’s essential to know the details of the Ram 1500 specs by year, including the bolt pattern history.
This is key for those wanting to upgrade or swap their wheels. Here’s a look at the bolt patterns for different years.
1994–2001: 5×139.7mm
Between 1994 and 2001, the Ram 1500 had a 5×139.7mm bolt pattern. This setup was consistent across these models. They used a ½”-20 lug nut size and had a center bore of 77.8mm.
These specs helped the earlier truck models meet typical load needs while ensuring good performance and fit.
2002–2008: 5×139.7mm
From 2002 to 2008, the bolt pattern stayed the same at 5×139.7mm. But, the lug nut size changed to 14mm x 1.5, with the center bore staying at 77.8mm.
This uniform bolt pattern made it easier for owners to find fitting aftermarket wheels since it matched earlier models.
2009–Present: 6×139.7mm
In 2009, a major change came with a new bolt pattern of 6×139.7mm. This version uses a 14mm x 1.5 lug nut size and has a slightly bigger center bore of 78.1mm.
These changes have enhanced stability, important for bigger tires and heavier loads, suiting today’s driving needs better.
Factors Affecting Bolt Pattern Compatibility
When picking wheels for your Ram 1500, understanding bolt pattern compatibility is key. Lug count, bolt circle diameter, and wheel offset are crucial factors.
They deeply impact your vehicle’s performance, safety, and how long it lasts.
Lug Count and Its Importance
The number of lugs on a Ram 1500 can change with different models. For example, some have a 5-lug setup, and others come with 6.
Not having the right lug count can cause problems like bad handling and uneven tire wear. It’s vital to match the lug count when getting new wheels to prevent them from coming off while driving.
Knowing Bolt Circle Diameter
Bolt Circle Diameter (BCD) is about measuring the space between lug holes across from each other. The Ram 1500 uses a 5×139.7 mm (5×5.5 inch) bolt pattern for models made before 2019, and a 6×139.7 mm (6×5.5 inch) for newer ones.
If the BCD doesn’t match, your new wheels won’t fit right, which can make driving unsafe.
Wheel Offset and Backspacing Considerations
Wheel offset matters because it affects how the wheels fit near the wheel well. The right offset and backspacing stop the wheels from rubbing on parts of the car.
This prevents damage and keeps your ride safe. Picking wheels with the correct offset and backspacing makes your car handle better and drive smoother.
Identifying Your Ram 1500 Bolt Pattern
To find the bolt pattern of your Ram 1500, you’ll need to take a few steps. You’ll measure and check different things to make sure you get the right wheel fitment.
- Count the Lug Holes: Start by figuring out if your truck has 5 or 6 lug holes. Knowing this is key to identify the correct bolt pattern.
- Measure the Bolt Circle Diameter:
- For 5-lug patterns, measure from the middle of one hole to the far edge of the hole across from it.
- For 6-lug patterns, measure the distance across the circle that the lugs make.
- Check Model Year: The year your vehicle was made can tell you more about the bolt pattern.
- Consult Owner’s Manual: This book often has the exact specs for fitting wheels to your truck.
- Use Professional Tools: For better accuracy, use bolt pattern gauges or calipers to measure the bolt circle diameter.
Gathering this information helps you fully understand the bolt pattern of your Ram 1500. This ensures correct wheel fit and safety when driving.

Common Mistakes To Avoid When Choosing Wheels
Picking the right wheels for your Ram 1500 is tricky. Many owners mess up when it comes to wheel fitting. Knowing what to avoid makes sure your vehicle runs smoothly.
Measuring Mistakes
Getting the measurements right is key for a good wheel fit. Some mistakes people often make include:
- Measuring next to each other lug holes, not skipping one, can mess up bolt circle diameter numbers. This may cause fitting problems.
- Using the wrong tools, like a tape measure instead of a caliper, leads to bad measurements. This increases the chances of choosing the wrong wheels.
- Not paying attention to hub bore size can make fitting even harder. It might lead to big compatibility issues with your Ram 1500.
Assumptions About Compatibility
Thinking all Ram 1500 models have the same bolt pattern is a big mistake. Different years mean different specs. Keep in mind:
- Various years have different bolt patterns. Always double-check your model’s needs before buying wheels.
- Sometimes, you might need hub adapters to fit wheels from other models. This highlights the need for correct information.
- Looking into what the manufacturer suggests for wheel compatibility can save you from expensive mistakes.
