2014 Ram 1500 Lug Pattern: Bolt Pattern & Wheel Specs
The 2014 Ram 1500 lug pattern is 5 x 139.7mm (5 x 5.5 inches), which is the standard configuration for all 4th generation half-ton models. To ensure a safe fitment, you must also match the 77.8mm center bore and M14 x 1.5 thread pitch used on these vehicles.
🎯 Key Takeaways
- The exact lug pattern is 5×139.7mm, commonly known as 5×5.5 inches.
- All 2014 Ram 1500 trim levels utilize this identical 5-lug configuration.
- The recommended wheel torque setting for this model is 130 lb-ft.
- A center bore of 77.8mm is required for proper hub-centric mounting.
- Standard lug nuts for the 2014 model year use M14 x 1.5 threading.
The 2014 Ram 1500 uses a 5 x 139.7mm lug pattern, which is also commonly referred to in the United States as the 5 x 5.5-inch bolt pattern. Whether you are upgrading to aggressive aftermarket rims or searching for a matching spare at a yard, this specific five-lug configuration is the non-negotiable measurement you need. This pattern ensures the wheel physically fits over your studs and sits flush against the hub assembly. Unlike the heavy-duty Ram 2500 or 3500 models that utilize an 8-lug setup, the half-ton 1500 relies on this classic wide five-bolt layout.
Getting this measurement right is the difference between a seamless installation and a costly return shipping fee. Using the wrong bolt pattern can lead to dangerous vibrations or even catastrophic wheel failure if you attempt to force a “close-enough” fit. Beyond just the lug count, the 2014 model year sits at a specific hardware intersection. You must verify your thread pitch and center bore alongside the primary bolt pattern to ensure your new wheels are truly safe for the road.
Decoding the 5×139.7mm Bolt Pattern for 2014 Models
The “5” in the 5 x 139.7mm pattern indicates the number of lug holes on your hub. The “139.7mm” represents the diameter of the imaginary circle formed by the centers of those holes. Because this is an odd-numbered 5-lug setup, you cannot simply measure directly from one hole to the next to find the diameter. Instead, you measure from the back of one hole to the center of the second hole across from it to approximate the measurement.
Metric vs. Imperial: 5×139.7mm vs. 5×5.5″
In the world of Ram trucks, you will hear these two terms used interchangeably. The measurement 139.7 millimeters converts exactly to 5.5 inches. Most modern aftermarket wheel manufacturers list their products using the metric designation, but classic off-road wheel brands often stick to the imperial measurement. Both are correct for your 2014 Ram 1500. Knowing both terms helps you search more effectively across different retail platforms.
- Bolt Pattern: 5 x 139.7mm (5 x 5.5″)
- Lug Count: 5 studs per wheel
- Compatibility: This pattern fits Ram 1500 generations from 1994 through 2018.
- Commonality: Also shared with some older Ford F-150s (pre-1997) and Dodge Dakotas.
Identifying the Pattern on Your Truck
If you are looking at your 2014 Ram 1500, you will see five distinct studs protruding from the brake rotor or drum. Do not confuse this pattern with the 5 x 127mm (5 x 5″) pattern found on many Jeep models. While they look similar to the naked eye, the Jeep pattern is smaller and will not slide over your Ram’s studs. Always double-check the box or the stamping on the inner barrel of the wheel to confirm the 139.7mm spacing before you mount a tire.
Master the 2014 Ram 1500 Lug Pattern in 7 Simple Steps
Understanding the specific wheel specifications for your 2014 Ram 1500 is the most critical step before purchasing new rims, rotating your tires, or performing brake maintenance. This guide covers the exact lug pattern, thread pitch, and torque requirements for the fourth-generation Ram 1500. Following these steps ensures that your wheels remain securely fastened to the hub, preventing catastrophic mechanical failure while driving. Whether you are upgrading to aggressive off-road wheels or simply performing a routine seasonal tire swap, mastering these measurements will give you the confidence to handle your truck’s wheel assembly like a professional technician.
Step 1: Identifying the 5×139.7 Lug Pattern
What you need: Owner’s manual, a clean rag, and a flashlight to inspect the wheel hub.
Instructions: The 2014 Ram 1500 utilizes a 5-lug bolt pattern, specifically the 5×139.7mm configuration (often referred to in the Imperial system as 5×5.5 inches). The first number “5” represents the number of lug holes, while “139.7” represents the diameter of the imaginary circle formed by the centers of those lugs. It is vital to recognize that while some other trucks use a 5-lug setup, the spacing on the Ram is unique to larger half-ton platforms. Before ordering any aftermarket wheels, you must verify that the wheel is drilled specifically for 139.7mm. Using a pattern that is “close” but not exact will result in sheared wheel studs and wheel loss.
Pro Tip: Always double-check the model year of your truck. While the 2014 uses the 5×139.7 pattern, the newer 2019+ Ram 1500 (DT models) switched to a 6-lug pattern, so never assume all Ram wheels are interchangeable.
Step 2: Measuring for Confirmation
What you need: A tape measure or a dedicated bolt pattern gauge.
Instructions: To verify the pattern on a 5-lug wheel, you cannot simply measure from one hole to the next adjacent hole. Instead, you must measure from the back of one lug hole to the center of the second hole away from it (skipping one lug). This should result in a measurement of approximately 5.5 inches or 139.7mm. If you are measuring the hub itself, measure from the center of one stud to the imaginary circle that passes through the centers of all five studs. This confirmation step is essential if you are buying used wheels from a private seller who may be unsure of the exact fitment for their previous vehicle.
Pro Tip: Invest in a plastic bolt pattern gauge; they are inexpensive and eliminate the guesswork associated with using a standard tape measure on a circular pattern.
Step 3: Verifying the Center Bore and Hub-Centricity
What you need: A digital caliper and a wire brush.
Instructions: The center bore of the 2014 Ram 1500 is 77.8mm. This is the diameter of the hole in the center of the wheel that fits over the hub’s pilot. The Ram 1500 is designed as a hub-centric system, meaning the hub—not the lug studs—carries the weight of the vehicle and centers the wheel. When selecting aftermarket wheels, ensure the center bore is at least 77.8mm. If the wheel has a larger bore (common in universal aftermarket wheels), you must use hub-centric rings to fill the gap. Failure to do so can lead to persistent vibrations at highway speeds and excessive stress on the wheel studs, which are only meant to provide clamping force.
Pro Tip: Use a wire brush to clean any rust or debris from the hub pilot before mounting a wheel to ensure the center bore seats perfectly flush against the hub face.
Step 4: Selecting the Correct Lug Nuts and Thread Pitch
What you need: A 22mm or 7/8-inch deep-well socket and a 14×1.5mm lug nut sample.
Instructions: For the 2014 model year, Ram transitioned to a metric thread pitch for the 1500 series. The studs are 14mm x 1.5. This is a departure from older Dodge trucks that used 9/16-18 threads. Using the wrong thread pitch will instantly strip the threads on both the stud and the nut, requiring a costly hub or stud replacement. Additionally, pay attention to the “seat” of the lug nut. Factory Ram wheels use a conical (acorn) seat. If your aftermarket wheels require a different seat type—such as a flat mag seat or a ball seat—you must replace the nuts accordingly to ensure proper clamping pressure across the wheel surface.
Pro Tip: Never use an impact wrench to start the lug nuts. Always thread them on by hand for at least three full turns to prevent cross-threading the 14×1.5 studs.
Step 5: Accounting for Wheel Offset and Backspacing
What you need: A straightedge and a ruler.
Instructions: The stock offset for a 2014 Ram 1500 wheel is typically around +19mm or +20mm. Offset determines how far the wheel sits in or out of the wheel well. On this specific truck, the upper control arm (UCA) sits very close to the inner sidewall of the tire. If you choose a wheel with too much positive offset, or a tire that is too wide, the rubber will rub against the UCA during turns. Conversely, a negative offset will push the wheels out past the fenders, giving a wider stance but increasing the scrub radius and puting more strain on the wheel bearings. Aim for an offset between 0mm and +20mm for a balanced fitment on most leveling kits.
Pro Tip: If you plan on installing 35-inch tires, you will likely need a wheel with a lower offset (closer to 0mm or even -12mm) to clear the suspension components.
Step 6: Mounting the Wheel Using the Star Pattern
What you need: A floor jack, jack stands, and your hands.
Instructions: Once you have verified the 5×139.7 pattern and the 14×1.5 lug nuts, lift the truck using a secure jacking point and support it with jack stands. Slide the wheel onto the hub, ensuring it is flush against the rotor face. Begin installing the lug nuts by hand in a “star” or “criss-cross” pattern. This means if you start at the top (12 o’clock), the next nut should be the bottom-right (4 o’clock), followed by the top-left (10 o’clock), then the top-right (2 o’clock), and finally the bottom-left (8 o’clock). This pattern ensures the wheel is pulled evenly onto the hub, preventing it from seating at an angle which causes “wobble” and uneven tire wear.
Pro Tip: Keep the tire slightly off the ground while snugging the nuts so the wheel can center itself on the hub without the weight of the truck interfering.
Step 7: Torquing to Factory Specifications
What you need: A calibrated torque wrench and a 22mm socket.
Instructions: The final and most important step is applying the correct torque. For a 2014 Ram 1500, the factory recommended torque spec is 130 lb-ft (176 Nm). Set your torque wrench to this value and tighten the lugs in the same star pattern used in the previous step. You should hear a distinct “click” when the target torque is reached. Do not over-torque, as this can stretch the studs or warp the brake rotors. Conversely, under-torquing can lead to the lug nuts backing off while driving. After driving approximately 50 to 100 miles on new wheels, re-torque the nuts to 130 lb-ft to account for any metal compression or settling.
Pro Tip: Avoid using “torque sticks” on an impact wrench for the final pass. Only a manual click-type or digital torque wrench provides the accuracy needed for safe wheel installation.
✅ Final Checklist
- Confirmed the bolt pattern is exactly 5×139.7mm (5×5.5″).
- Verified the center bore is 77.8mm or used hub-centric rings.
- Ensured lug nuts are 14×1.5mm thread pitch with the correct seat type.
- Tightened lug nuts in a 5-point star pattern to ensure even seating.
- Finalized all lug nuts to the factory specification of 130 lb-ft.
Important Notes:
- Safety: Never work under a vehicle supported only by a hydraulic jack; always use rated jack stands.
- When to seek professional help: If you experience steering wheel vibration after installation despite proper torquing, your wheels may need professional dynamic balancing or the hub-centric alignment may be off.
- Estimated Time and Cost: This process takes approximately 45–60 minutes for all four wheels. DIY cost is $0 if you own the tools, while a professional shop may charge $50–$100 for a mount and balance.
Critical Fitment Specs: Center Bore, Thread Pitch, and Offset
While the bolt pattern gets the wheel onto the studs, secondary specifications determine if the wheel sits safely and rotates without wobbling. For the 2014 Ram 1500, the center bore and thread pitch are just as critical as the lug pattern itself. Ignoring these can lead to sheared studs or wheels that won’t stay tight.
The Hub-Centric Standard: 77.8mm Center Bore
The center bore is the large hole in the middle of the wheel that slides over the hub of your truck. The 2014 Ram 1500 features a 77.8mm center bore. This is a hub-centric design. This means the hub—not just the lug nuts—supports the weight of the vehicle and centers the wheel. If you buy aftermarket wheels with a larger bore, you must use hub-centric rings to fill the gap. This prevents high-speed vibrations and ensures the wheel remains perfectly centered during rotation.
Thread Pitch: 9/16″-18 vs M14 x 1.5
The 2014 model year is unique because it sits near a transition in lug nut hardware for the Ram brand. Most 2014 Ram 1500s use 9/16″-18 thread studs. However, some production runs began moving toward the M14 x 1.5 metric sizing that became the standard shortly after. It is vital to check your specific truck before buying new lug nuts. Using the wrong thread will strip the studs and require an expensive hub replacement.
- Standard Stud Size: 9/16″-18 (Most common for 2014)
- Metric Stud Size: M14 x 1.5 (Check late-year builds)
- Wheel Torque: 130 lb-ft (176 Nm) for all 5 lugs
- Lug Nut Style: Typically a 60-degree conical seat
Understanding Offset and Backspacing
The stock offset for a 2014 Ram 1500 factory wheel is typically around +19mm. This measurement determines how far the wheel sits in or out of the wheel well. If you move to a negative offset, such as -12mm, the wheels will “poke” out further from the fenders. While this provides a wider, more aggressive stance, it also changes the scrub radius. A wider stance may require a leveling kit to avoid rubbing the inner fender liners when you turn the steering wheel to full lock.
Compatibility Across 4th Generation Ram 1500 Trim Levels
A common question among truck owners is whether high-end trims like the Laramie or Longhorn use different hardware than the base Tradesman. The short answer is no. Regardless of the luxury features inside the cabin or the engine under the hood, the 2014 Ram 1500 maintains the same 5×139.7mm bolt pattern across the entire lineup. This consistency makes it incredibly easy to find replacements or upgrades.
Does Trim Level Change the Bolt Pattern?
Whether you are driving a Tradesman, SLT, Big Horn, Laramie, or Sport, the wheel mounting specifications remain identical. This is a huge advantage for owners looking to upgrade their look on a budget. You can easily swap a set of 20-inch polished aluminum wheels from a Limited onto a Tradesman that originally came with 17-inch steel wheels without worrying about the studs aligning.
- Universal Fit: All 2014 1500 trims use the 5-lug configuration.
- Interchangeability: OEM wheels from any 2014 trim are cross-compatible.
- Heavy Duty Note: Remember that this does not apply to the Ram 2500 or 3500, which use an 8-lug pattern designed for much heavier towing loads.
Interchangeability with Other Model Years
The 2014 model sits right in the heart of the 4th Generation (2009–2018). This means your wheel options aren’t limited to just the 2014 catalog. In fact, wheels from a 2010 Ram 1500 or even a 2022 Ram 1500 Classic will fit your truck perfectly. Because Ram kept this pattern for so many years, the secondary market is flooded with compatible “take-off” wheels, allowing for affordable styling updates using newer factory designs.
Choosing Aftermarket Wheels: Factors for a Perfect Match
Knowing your lug pattern is the first step, but it isn’t the only one. When you move away from factory rims to aftermarket options, other measurements become just as critical to ensure your tires don’t rub against the suspension or stick out too far from the fenders.
Understanding Offset and Backspacing
Offset determines where the wheel sits in relation to the hub. Most factory 2014 Ram wheels have a positive offset (around +19mm). If you choose a wheel with a negative offset, the wheel will poke out further, giving the truck a wider, more aggressive stance. However, be careful—too much “poke” can lead to “rubbing” when you turn the steering wheel to full lock, especially if you have upgraded to larger tires.
- Positive Offset: Tucks the wheel inward toward the truck (Factory style).
- Zero/Negative Offset: Pushes the wheel outward for a wider stance (Off-road style).
- Pro Tip: If you plan on installing wider-than-stock tires, a lower offset helps clear the upper control arms.
The Importance of Center Bore
The center bore is the hole in the middle of the wheel that fits over the hub. For a 2014 Ram 1500, the hub bore is 77.8mm. You should ideally look for “hub-centric” wheels that fit snugly onto this hub. This ensures the weight of the truck is supported by the hub rather than just the lug studs. If you find a set of wheels with a larger bore, you will need to purchase “hub-centric rings” to bridge the gap and prevent annoying vibrations at highway speeds.
Conclusion
Upgrading the wheels on your 2014 Ram 1500 is one of the most effective ways to personalize your truck’s appearance and performance. By sticking to the 5×139.7mm (5×5.5) lug pattern and paying close attention to the 77.8mm center bore, you can shop with total confidence. Whether you are hunting for a set of rugged off-road rims or sleek street wheels, the 4th generation Ram platform offers plenty of flexibility.
Before you buy, your next steps should be to double-check the offset of your chosen wheels and ensure you have the correct lug nuts to match the new seat type. Once you have those specs locked in, you’re ready to transform your ride. Get out there and find the perfect set of wheels!
