So, you're wondering if you can slap those shiny 5th gen Ram 2500 wheels onto your trusty 4th gen? It's a question that many Ram owners have, and the answer isn't always a straightforward yes or no. Let's dive into the nitty-gritty of wheel compatibility between these generations of Ram trucks. We'll explore bolt patterns, offset, and everything else you need to consider before making a swap. By the end of this article, you'll know exactly what to look for and whether or not those 5th gen wheels will work on your 4th gen Ram.

Understanding the Basics of Wheel Compatibility

Before we get into the specifics of Ram generations, let's cover some fundamental aspects of wheel compatibility. Understanding these concepts is crucial for ensuring a safe and proper fit. Several factors determine whether a wheel will work on your vehicle:

• Bolt Pattern: This is the configuration of the wheel studs on your vehicle's hub. It's expressed as the number of studs and the diameter of the circle they form (e.g., 8x165.1mm). The bolt pattern on the wheels must match the bolt pattern on your truck's hubs for the wheel to be mounted correctly.
• Center Bore: This is the diameter of the hole in the center of the wheel that centers it on the hub. The center bore of the wheel should match or be slightly larger than the hub diameter of your vehicle. If the center bore is smaller, the wheel won't fit. If it's larger, you might need hub-centric rings to ensure proper centering and prevent vibrations.
• Offset: This is the distance between the wheel's mounting surface and its centerline. Offset affects how the wheel sits in the wheel well. A positive offset means the mounting surface is closer to the outside of the wheel, tucking the wheel further in. A negative offset pushes the wheel outward. The correct offset is crucial for avoiding rubbing against suspension components or the body of the truck.
• Wheel Diameter and Width: The diameter of the wheel must be compatible with the tire size you intend to use. The width of the wheel affects the tire's profile and how it sits on the wheel. Ensure that the wheel width is within the recommended range for your chosen tire size.
• Load Rating: This is the maximum weight each wheel is designed to support. It's crucial to choose wheels with a load rating that meets or exceeds the requirements of your truck, especially if you frequently haul heavy loads or tow trailers. Ignoring the load rating can lead to wheel failure and dangerous situations.

Keeping these factors in mind, you'll be well-equipped to evaluate the compatibility of different wheels for your Ram truck. Make sure to double-check all specifications before making any decisions.

4th Gen vs. 5th Gen Ram 2500: Key Differences

Okay, let's break down the critical differences between 4th gen (2010-2018) and 5th gen (2019+) Ram 2500 trucks that affect wheel compatibility. Knowing these distinctions will help you determine if a wheel swap is feasible. While they share the Ram name, some underlying changes can impact your wheel options.

• Bolt Pattern: Good news, guys! Both the 4th and 5th gen Ram 2500 trucks use the same 8x165.1mm (8x6.5 inch) bolt pattern. This means the bolt pattern itself won't be an issue when considering a wheel swap. You're off to a good start!
• Center Bore: This is where things get a little more interesting. The 4th gen Ram 2500 typically has a center bore of 121.3 mm. The 5th gen Ram 2500 also uses a center bore of 121.3 mm. Because they are the same, there are no compatibility issues here.
• Offset: Offset is a crucial factor to consider. The offset on the 4th gen Ram 2500 wheels generally ranges from +43mm to +57mm. The 5th gen Ram 2500 wheels typically have a higher offset, usually around +57mm to +63mm. This difference in offset means that the 5th gen wheels will sit slightly further inward compared to the 4th gen wheels. This can be a problem if you have larger tires or if you're concerned about the wheel rubbing against the suspension components.
• Wheel Size and Design: While both generations offer a variety of wheel sizes (typically ranging from 17 to 20 inches), the design and styling differ significantly. The 5th gen wheels often have a more modern and aggressive look. This is a primary reason why many 4th gen owners are interested in swapping to the newer wheels.
• Brake Caliper Clearance: Although less common, there's a possibility of brake caliper clearance issues, especially if you're running aftermarket or upgraded brake systems. Always double-check that the 5th gen wheels provide enough clearance for your brake calipers to avoid any interference.

Will 5th Gen Wheels Fit on a 4th Gen Ram 2500? The Verdict

So, can you bolt those 5th gen Ram 2500 wheels onto your 4th gen without any headaches? Here's the lowdown: In many cases, yes, they will fit, but with a few caveats. The matching bolt pattern and similar center bore mean that the wheels can physically be mounted. However, the higher offset of the 5th gen wheels might cause some issues. Let's explore this further.

Potential Issues and How to Address Them

• Rubbing: The most common problem you might encounter is rubbing, especially on the inside of the wheel well or against the suspension components. This is due to the higher offset of the 5th gen wheels, which pushes them further inward. To combat this, you have a couple of options:
  • Wheel Spacers: These are flat discs that you install between the wheel and the hub. They effectively reduce the offset, pushing the wheel further outward. If you're experiencing rubbing, a small wheel spacer (e.g., 1/4 inch to 1 inch) might be enough to solve the problem. Make sure to use high-quality wheel spacers and follow the manufacturer's instructions carefully. Also, be aware that using wheel spacers can put additional stress on your wheel bearings and suspension components.
  • Adjusting Suspension: In some cases, minor suspension adjustments can provide additional clearance. This might involve adjusting the ride height or modifying the fender liners. However, this is a more complex solution that might require professional help.
• Appearance: The higher offset can also affect the overall appearance of your truck. The wheels might look slightly tucked in, which some people find less appealing. Wheel spacers can also address this aesthetic issue by pushing the wheels out to a more flush position with the fenders.
• TPMS Compatibility: Tire Pressure Monitoring System (TPMS) sensors can sometimes be an issue when swapping wheels between different generations. The TPMS sensors in the 5th gen wheels might not be compatible with the TPMS system in your 4th gen truck. You have a few options here:
  • Re-use Your 4th Gen TPMS Sensors: You can remove the TPMS sensors from your 4th gen wheels and install them in the 5th gen wheels. This is usually the simplest and most cost-effective solution.
  • Purchase Compatible TPMS Sensors: You can buy new TPMS sensors that are compatible with both your 4th gen truck and the 5th gen wheels. Make sure to program the new sensors to your truck's TPMS system.
  • Ignore TPMS (Not Recommended): You can choose to ignore the TPMS system altogether. However, this is not recommended as it can compromise your safety and fuel efficiency. A properly functioning TPMS system alerts you to low tire pressure, which can prevent accidents and improve gas mileage.

Step-by-Step Guide to Swapping Wheels

If you've decided to proceed with swapping your 4th gen wheels for 5th gen wheels, here's a step-by-step guide to help you through the process: Always put safety first.

1. Gather Your Tools and Equipment: You'll need a jack, jack stands, a lug wrench, a torque wrench, wheel spacers (if needed), TPMS tools (if needed), and any other tools specific to your truck or wheels.
2. Prepare Your Work Area: Park your truck on a level surface, engage the parking brake, and chock the wheels that will remain on the ground.
3. Loosen the Lug Nuts: Use the lug wrench to loosen the lug nuts on the wheels you'll be removing. Don't remove them completely at this stage.
4. Jack Up the Truck: Use the jack to lift the truck until the wheel is off the ground. Place jack stands under the frame for safety.
5. Remove the Wheel: Finish removing the lug nuts and carefully remove the wheel.
6. Install Wheel Spacers (If Needed): If you're using wheel spacers, place them over the wheel studs.
7. Mount the 5th Gen Wheel: Carefully align the 5th gen wheel with the wheel studs and push it onto the hub. Install the lug nuts by hand, tightening them in a star pattern.
8. Lower the Truck: Remove the jack stands and lower the truck until the wheel is on the ground.
9. Torque the Lug Nuts: Use the torque wrench to tighten the lug nuts to the manufacturer's specified torque. Again, tighten them in a star pattern.
10. Repeat for Remaining Wheels: Repeat steps 3-9 for the remaining wheels.
11. Check TPMS Sensors: If you've reused or replaced the TPMS sensors, make sure they are functioning correctly. Drive the truck for a few minutes to allow the TPMS system to recalibrate.
12. Test Drive and Inspect: Take the truck for a test drive and listen for any rubbing or unusual noises. Inspect the wheels and lug nuts after the test drive to ensure everything is secure.
