Getting the right wheels for your 2019 Ram 1500 starts with knowing one key detail: the lug pattern.
As a Ram owner who spent hours researching this topic, I know firsthand how confusing it can be to find clear information.
Here’s the simple truth: The lug pattern affects which wheels fit your truck and keeps you safe on the road.
When I first needed new wheels, I made mistakes that cost me time and money.
But don’t worry – I’ve done the homework for you.
In this article, I’ll explain everything about the 2019 Ram 1500’s lug pattern.
You’ll learn:
- The exact measurements you need
- Which wheels will fit
- Common fitting mistakes to avoid
I’ve owned my Ram for three years and tested different wheel setups.
Let me help you get it right the first time.
What is the Lug Pattern for the 2019 Ram 1500?
Let me break down what a lug pattern is in simple terms.
The lug pattern tells you two things: how many lug nuts your wheel needs and how far apart they are.
Think of it as a circle of bolts holding your wheel to your truck.
If you get this wrong, your new wheels won’t fit—it’s that simple.
The 2019 Ram 1500 has a 6×139.7mm lug pattern. Let’s decode what that means:
- 6: The number of lug nuts on each wheel
- 139.7mm: The diameter of the circle these lugs make
I learned this the hard way: not all truck wheels use the same pattern.
That’s why knowing your Ram’s exact pattern matters for:
- Buying new wheels
- Finding spare wheels
- Switching to aftermarket options
Quick safety note: Even if wheels look like they might fit, using the wrong lug pattern can be dangerous.
I always double-check these measurements before buying new wheels.
My tip?
Write down these numbers (6×139.7mm) and keep them handy.
You’ll need them every time you shop for wheels.
Understanding the 2019 Ram 1500 Lug Pattern and Its Compatibility
1. How The Lug Pattern Affects Your Wheel Options
I’ve tested many wheel setups on my Ram 1500, and the lug pattern clearly limits what you can use.
With the 6×139.7mm pattern, you have many options – but not every wheel will fit.
The good news is that many truck brands use this same pattern.
This means you can find wheels from various makers that will perfectly fit your Ram.
2. Finding Compatible Aftermarket Wheels
When shopping for new wheels, you’ll need to match not just the lug pattern but also these key measurements:
- Center bore size
- Wheel offset
- Load rating
I’ve found that most major wheel brands offer options for the Ram 1500.
Before buying, make sure to check all specs.
3. Different Tire Setups That Work
Your lug pattern stays the same no matter what tire size you choose.
From my experience, you can run:
- Stock size tires
- Slightly larger all-terrain tires
- Mud tires (with proper lift)
4. Common Compatibility Issues
Here’s what I watch out for when fitting new wheels:
- Hub-centric vs. lug-centric designs
- Proper wheel offset range
- Brake caliper clearance
Each of these factors matters just as much as the lug pattern.
I once bought wheels with the right pattern but the wrong offset – they rubbed against my brakes.
5. Performance Impact
The right wheel setup, paired with your lug pattern, affects:
- How your truck handles
- Fuel economy
- Brake performance
- Overall ride quality
I notice the biggest difference in handling when switching between light and heavy wheels, even with the same lug pattern.
List of the Correct Lug Pattern for Different 2019 Ram 1500 Models
After checking every model and trim level, I can confirm that all 2019 Ram 1500s use the same base lug pattern.
Here’s the detailed breakdown I’ve put together from my research:
Standard Models and Their Lug Patterns
| Model Trim | Lug Pattern | Bolt Size | Center Bore |
|---|---|---|---|
| Tradesman | 6×139.7mm | M14x1.5 | 77.8mm |
| Big Horn | 6×139.7mm | M14x1.5 | 77.8mm |
| Laramie | 6×139.7mm | M14x1.5 | 77.8mm |
| Rebel | 6×139.7mm | M14x1.5 | 77.8mm |
| Limited | 6×139.7mm | M14x1.5 | 77.8mm |
Special Notes I’ve Found
- 4×2 and 4×4 models use the same pattern
- Short and long bed versions are identical
- All-wheel sizes (17″, 18″, 20″, 22″) share this pattern
Important differences to watch for
- Bolt length might vary by wheel type
- Wheel offset changes with trim level
- Some models need specific lug nuts
I’ve double-checked these specs with dealers and my own hands-on work.
You can trust these numbers when shopping for new wheels.
How to Identify the Correct Lug Pattern for a Specific 2019 Ram 1500
Tools you’ll need
- Measuring tape or ruler (metric)
- Paper and pencil
- A helper (makes it easier)
Let me show you how to check your Ram’s lug pattern yourself.
I do this whenever I want to be 100% sure about wheel fitting.
Step 1: Find the Circle
Pick any lug bolt on your wheel.
Count the total bolts – you’ll find six of them.
Mark your starting point with tape or chalk.
Step 2: Measure Correctly
Here’s the key part I learned through trial and error: You need to measure from the center of one lug to the center of the one directly across.
This gives you the 139.7mm measurement.
Pro tip: If you’re using inches, look for about 5.5 inches between centers.
Step 3: Double-Check Your Work
I always measure twice between different pairs of lugs.
This helps catch any mistakes.
If you get the same number each time, you’re good to go.
Common Mistakes to Avoid
- Don’t measure from edge to edge
- Don’t skip the metric conversion
- Don’t guess at the center points
I keep these measurements on my phone.
This makes wheel shopping much easier.
You should, too – it’ll save you time later.
Quick Safety Check: If your measurements are off by more than 1mm from 139.7mm, measure again.
Small errors here can mean big problems with wheel fitting.

How to Maintain the Lug Pattern on Your 2019 Ram 1500
1. Check Your Lug Nuts Regularly
Let me share what I’ve learned about keeping lug nuts tight.
After installing new wheels, check them every 50 miles.
Then, make it part of your monthly checks.
I use a torque wrench set to 130 ft-lbs, which is the right spec for our Ram 1500.
2. Watch for Signs of Wear
When you clean your truck, look at the wheel studs.
I check mine every time I wash the wheels.
If you see rust, cracks, or bent studs, fix them immediately.
Bad studs can wreck your wheels and put you in danger.
3. Clean the Mounting Surface
Here’s my cleaning routine:
- Wipe the hub surface clean
- Brush the lug nuts and studs
- Remove any rust spots
- Keep threads free of dirt
4. Use the Right Tools
I keep these tools in my truck:
- Torque wrench
- Socket set
- Wire brush
- Anti-seize compound
5. Follow the Pattern
When you tighten lug nuts, use a star pattern. I start hand-tight, then:
- Set torque wrench to 130 ft-lbs
- Work in a star pattern
- Check each nut twice
- Listen for the wrench’s click
6. Seasonal Checks
I check my lug nuts when I:
- Switch to winter tires
- Notice steering shake
- Hit big bumps
- Drive on rough roads
Safety tip: Stop and check the lug nuts if you hear clicking from your wheels.
Better safe than sorry.
