Understanding the 2020 Ford Ranger Lug Pattern
Let’s get straight to the heart of it. The 2020 Ford Ranger utilizes a 6×139.7mm lug bolt pattern. This measurement is composed of two parts: the number of lug holes and the diameter of the bolt circle.
The ‘6’ signifies that there are six lug studs (or bolt holes) on the wheel hub. The ‘139.7mm’ is the diameter of the imaginary circle that passes through the center of each of these lug studs. In simpler terms, it’s the distance across the wheel hub where the studs are positioned.
This particular bolt pattern is quite common among trucks and SUVs, especially those with a robust, body-on-frame construction. For the 2020 Ford Ranger, this specific pattern ensures a secure and reliable connection between the wheel and the hub assembly, which is vital for carrying loads and handling various terrains.
What Does 6×139.7mm Really Mean for Your Ranger?
When you hear “6×139.7mm,” it’s more than just numbers. It’s the blueprint for how your wheels attach to your truck. This pattern is often referred to as 6×5.5 inches, as 139.7mm is approximately equal to 5.5 inches. Mechanics and enthusiasts often use both measurements interchangeably.
This means any wheel you consider for your 2020 Ford Ranger must have a bolt pattern that matches this specification. If you try to install wheels with a different lug pattern, they simply won’t fit. It’s a fundamental compatibility check.
For the Ranger, this bolt circle diameter is designed to accommodate the forces and stresses typical for a mid-size pickup truck. It provides a stable platform for the wheels to rotate on, distributing the load effectively.
Checking Your Current Wheels and Hubs
Before you even think about buying new wheels, it’s a good practice to confirm your existing setup. While the 2020 Ford Ranger has a standard pattern, it’s always best to double-check, especially if you’ve had aftermarket wheels installed previously. How to Check:
- Count the Lugs: Look at your wheel. You should see six lug nuts holding it in place.
- Measure the Bolt Circle: This is a bit trickier. If you have the wheel off, you can measure from the center of one stud to the center of a stud directly across from it (this is the diameter). Alternatively, you can measure from the edge of one stud to the edge of the opposite stud and add the diameter of one stud. A simpler method if you have wheel off is to measure from the center of one stud to the center of an adjacent stud, then multiply that by 1.732 (for a 6-lug pattern). However, the most reliable way is to know the manufacturer’s specification.
- Consult Your Owner’s Manual: Your Ranger’s owner’s manual is the ultimate source of truth for all specifications, including the lug pattern.
- Look for Markings: Sometimes, wheel manufacturers will stamp the bolt pattern onto the back of the wheel.
Remember, if you’re unsure, it’s always better to ask a professional. A quick call to a tire shop or mechanic can save you a lot of potential headaches and safety concerns.
Wheel Offset and Backspacing: Beyond the Lug Pattern
While the lug pattern is paramount for basic fitment, other critical dimensions determine how wheels sit on your truck and interact with suspension components. These are wheel offset and backspacing. Wheel Offset: This refers to the distance between the wheel’s mounting surface (where it bolts to the hub) and the centerline of the wheel. A positive offset pushes the wheel inward, while a negative offset pushes it outward. For the 2020 Ford Ranger, stock wheels typically have a positive offset to keep the wheels tucked within the fenders.
Backspacing: This is the measurement from the back of the wheel (the mounting surface) to the outer lip of the wheel. It’s a good indicator of how much clearance you have inside the wheel well.
When choosing aftermarket wheels, you’ll need to consider these alongside the 2020 Ford Ranger lug pattern. Mismatched offset or backspacing can lead to tires rubbing on fenders, suspension components, or brake calipers, causing damage and compromising safety. Always aim for wheels with an offset and backspacing that are close to the factory specifications unless you’re intentionally planning for a wider stance or larger tires.
Hub Bore Size: Another Crucial Dimension
Another often-overlooked specification is the hub bore size. This is the diameter of the raised center section on your wheel hub, which the wheel’s center hole is designed to fit over. While the lug pattern ensures the wheel bolts on, the hub bore ensures it sits centered and true.
For the 2020 Ford Ranger, the hub bore size is typically 93.1mm. Wheels designed for your Ranger should ideally have a hub bore of 93.1mm or larger. If the hub bore is larger, you’ll need to use hub-centric rings. These are small plastic or metal rings that fill the gap between the wheel’s larger bore and the truck’s smaller hub, preventing vibrations and ensuring the wheel is perfectly centered.
Wheels that are “universal” or designed for a wider range of vehicles might have a larger hub bore (e.g., 106mm or 110mm). In these cases, using the correct hub-centric rings is absolutely essential for a safe and smooth ride. If a wheel has the correct lug pattern but a smaller hub bore than your truck’s hub, it will not fit.
Common Wheel Upgrade Scenarios for the 2020 Ranger
Many Ranger owners look to upgrade their wheels for aesthetic reasons or to accommodate larger tires for off-roading. Understanding the 2020 Ford Ranger lug pattern is your first step.
Scenario 1: Aesthetic Wheel Upgrade
- You want a new look but plan to stick with the stock tire size.
- Focus on finding wheels with the 6×139.7mm bolt pattern, a similar offset and backspacing to your factory wheels, and the correct 93.1mm hub bore (or be prepared to use hub-centric rings).
- Common sizes for aftermarket wheels might be 17-inch, 18-inch, or even 20-inch, depending on your preference.
Scenario 2: Off-Road Tire and Wheel Setup
- You’re fitting larger, more aggressive tires for trails and want wheels that can handle the abuse.
- You’ll still need the 6×139.7mm bolt pattern.
- Often, off-road enthusiasts prefer wheels with a slightly negative offset or a wider wheel to push the tires out for better clearance and a more stable stance.
- Careful consideration of tire-to-fender and tire-to-suspension clearance is paramount. You might need to trim fenders or adjust suspension components.
- Wheel diameter often stays at 17 inches for off-road setups to allow for more tire sidewall, which improves ride comfort and off-road capability.
Scenario 3: Smaller Aftermarket Wheels
- While less common for trucks, some might opt for smaller diameter wheels (e.g., 16-inch) if they can find tires that fit and clear your brakes.
- Again, the 6×139.7mm lug pattern is non-negotiable.
Always consult with a reputable wheel and tire specialist when planning significant upgrades. They can advise on compatibility and potential fitment issues based on your specific goals.
Ensuring Safe Installation of Wheels
Once you have the correct wheels, proper installation is key to safety. This is where your knowledge of the 2020 Ford Ranger lug pattern, torque specifications, and tightening sequence comes into play. Tools You’ll Need:
- Torque Wrench: Absolutely essential. Overtightening can strip threads or warp rotors, while undertightening can lead to wheels coming loose.
- Appropriate Socket: Usually a 19mm or 21mm socket for lug nuts on modern trucks.
- Jack and Jack Stands: For safely lifting and supporting your Ranger.
- Wheel Chocks: To prevent the vehicle from rolling.
- Wire Brush: To clean rust and debris from the hub and lug studs.
Installation Steps:
- Park on a Level Surface: Engage the parking brake and place wheel chocks behind the wheels that will remain on the ground.
- Loosen Lug Nuts: Before lifting the vehicle, slightly loosen the lug nuts on the wheel you’re replacing.
- Lift and Support: Safely jack up your Ranger and support it with jack stands. Never work under a vehicle supported only by a jack.
- Remove Old Wheel: Unscrew the lug nuts completely and remove the old wheel.
- Prepare Hub and Wheel: Clean the wheel studs and the hub mounting surface with a wire brush to remove any dirt, rust, or old grease. Ensure the new wheel’s center bore is clean. If using hub-centric rings, install them now.
- Mount New Wheel: Carefully slide the new wheel onto the studs.
- Hand-Tighten Lug Nuts: Thread the lug nuts on by hand until they are snug. This helps prevent cross-threading.
- Star Pattern Tightening: Using your torque wrench, tighten the lug nuts in a star or criss-cross pattern. This ensures the wheel is seated evenly against the hub.
- Torque to Specification: Consult your owner’s manual or a reliable service manual for the exact torque specification for your 2020 Ford Ranger. For most Rangers, this is around 150 lb-ft (204 Nm). Tighten in stages (e.g., to 75 lb-ft, then to the final spec).
- Repeat for All Wheels: Follow the same procedure for all four wheels.
- Re-Torque After Driving: After driving approximately 50-100 miles, it is crucial to re-torque all lug nuts to the specified value. This accounts for any settling of the wheel on the hub.
Important Note: Never lubricate lug studs or lug nut seats unless explicitly stated by the manufacturer. This can lead to overtightening and damage. Use anti-seize compound only on the hub mating surface if recommended by the wheel manufacturer, and use it sparingly.
Troubleshooting Common Wheel Fitment Issues
Even with the correct lug pattern, you might encounter issues. Here are some common problems and how to address them:
Wheel Rubbing on Fenders or Suspension
Cause: Incorrect offset, backspacing, or oversized tires. Solution: For minor rubbing, you might be able to live with it or make minor fender liner adjustments. For significant rubbing, you’ll need wheels with a different offset/backspacing, or potentially trim fenders and suspension components. Always consult an expert for major modifications.
Vibrations at Speed
Cause: Unbalanced wheels, improperly seated wheels, or incorrect hub bore fitment (lack of hub-centric rings). Solution: Have your wheels balanced. Ensure wheels are properly torqued and seated. If the bore size is different from the hub, install the correct hub-centric rings.
Lug Nuts Not Seating Properly
Cause: The lug nuts are for a different bolt seat type (e.g., conical vs. spherical) or the wrong thread pitch. Solution: Ensure you are using the correct lug nuts for your aftermarket wheels. Many aftermarket wheels require specific types of lug nuts (e.g., tuner lug nuts for smaller holes). The thread pitch for the 2020 Ford Ranger is typically M14x1.5.
Brake Caliper Interference
Cause: The spokes of the aftermarket wheel are too close to the brake calipers. Solution: This often requires wheels with a different spoke design or a larger diameter wheel. Some aftermarket wheels are specifically designed with “big brake clearance” in mind.
