If you’re driving a Dual Rear Wheel (DRW) configuration, the heavier duty setup requires more torque at 180 ft-lbs.
The specs haven’t changed since 2014, showing RAM’s confidence in these values for optimal safety and performance.
How Do Different Lug Nut Types Affect Torque Requirements?
Not all lug nuts are created equal, and RAM uses two primary types that require different torque specs:
Cone-Type Lug Nuts:
- Typically found on steel wheels
- Feature a 60-degree conical seat
- Require 130 ft-lbs of torque
- You can identify these by their tapered shape
Flanged Lug Nuts:
- Common on aluminum wheels
- Have a flat bearing surface with an integrated washer
- Need 140 ft-lbs of torque
- Recognizable by their flat washer-like face
Knowing which type you have is essential since using the wrong torque spec can damage your wheels or compromise safety.
What Were the Historical RAM 2500 Torque Specs (1994-2013)?
If you’re driving an older RAM 2500, the specs were slightly different:
1994-2013 RAM 2500 Models:
- Single Rear Wheel: 135 ft-lbs
- Dual Rear Wheel: 145 ft-lbs
RAM increased the torque values in 2014 due to improvements in wheel stud materials and updated safety requirements. If you’re maintaining a classic RAM, these historical specifications are your go-to values.

This consistency in specifications makes it easier to maintain proper torque regardless of which recent RAM 2500 model you own.
What’s the Proper Wheel Installation Procedure?
Follow these steps for safe and effective wheel installation:
- Clean the Mounting Surfaces: Remove any dirt or corrosion from the wheel hub and the back of the wheel.
- Hand-Tighten First: Thread the lug nuts by hand in a star/crisscross pattern.
- Apply Torque Properly: Using a calibrated torque wrench, tighten in sequence:
- First pass: Tighten to about half the specified torque
- Second pass: Tighten to the full specified torque
- Always follow a star pattern (like moving from 12 to 6, then 3 to 9 o’clock, etc.)
- Verify Each Lug Nut: Double-check that each nut is tightened to the correct specification.
- Re-torque After Driving: Check torque again after 50-100 miles as wheels can settle.
This proper sequence ensures even pressure distribution and prevents warping or damage.
What Happens If You Get the Torque Wrong?
The consequences of incorrect torque can range from annoying to dangerous:
Over-tightening Risks:
- Warped brake rotors that cause vibration when braking
- Stretched or broken wheel studs
- Cracked wheels (especially aluminum ones)
- Difficulty removing wheels later
Under-tightening Risks:
- Wheels that wobble, causing uneven tire wear
- Loose wheels that can completely detach while driving
- Excessive stress on remaining lug nuts
- Damaged wheel studs from movement
Both scenarios can lead to serious safety issues, which is why proper torque is non-negotiable.
What Tools Do You Need for Proper Wheel Torque?
To get the job done right, you’ll need:
Essential Tools:
- Calibrated torque wrench rated for 100-200 ft-lbs
- Correct socket size (typically 21mm or 22mm for RAM trucks)
- Breaker bar for initial loosening of tight lug nuts
- Wire brush to clean mounting surfaces
- Anti-seize compound (optional but helpful in areas with road salt)
A quality torque wrench is worth the investment. Avoid using impact wrenches for final tightening as they can easily exceed the proper torque specification.
Does Wheel Material Affect Torque Requirements?
Yes, wheel material plays a significant role in torque specifications:
Steel Wheels:
- Generally use cone-type lug nuts
- Can sometimes tolerate slight over-torquing better than aluminum
- Typically require 130-135 ft-lbs on RAM 2500s
Aluminum Wheels:
- Usually paired with flanged lug nuts
- More susceptible to damage from improper torque
- Typically require 140 ft-lbs on RAM 2500s
The difference comes down to material properties and how pressure is distributed across the mounting surface.
Have There Been Any RAM Recalls Related to Wheel Torque?
While there haven’t been major recalls specifically for wheel torque issues on the RAM 2500, there have been related concerns:
- Around 2014-2015, some owners reported issues with stretched wheel studs
- RAM briefly reduced the recommended torque to 130 ft-lbs for M14 lug studs
- Current specifications returned to higher values after improvements to stud materials
These adjustments highlight RAM’s commitment to safety and reliability in their wheel fastening systems.
How Often Should You Check Wheel Torque?
Regularly checking your wheel torque is a smart maintenance habit:
Check your wheel torque:
- After any wheel removal or rotation
- When you notice vibration while driving
- After hitting severe potholes or curbs
- Every 5,000 miles as preventative maintenance
- Before long trips or heavy towing
This regular verification helps catch any loosening before it becomes a serious problem.
What’s the Difference Between Torque Sticks and Torque Wrenches?
When working on your RAM 2500’s wheels, you might encounter these two different tools:
Torque Sticks:
- Color-coded extension bars for impact wrenches
- Flex at predetermined torque values
- Convenient but less precise
- Good for initial tightening but not final torque
Torque Wrenches:
- Precision tools that measure applied force
- “Click” or indicate when you reach the target torque
- More accurate and reliable
- Essential for final tightening to spec
For safety’s sake, always finish with a proper torque wrench even if you use torque sticks for the initial work.
How Do Aftermarket Wheels Affect Torque Requirements?
Aftermarket wheels might come with different torque specifications:
- Always check the wheel manufacturer’s recommended torque
- Aftermarket wheels may require less torque than OEM specs
- Special lug nuts or bolts might come with specific requirements
- Some aftermarket wheels need frequent re-torquing initially
When in doubt, follow the wheel manufacturer’s guidelines rather than the vehicle specs.
Why Is the Star Pattern Important for Tightening?
The star or cross pattern isn’t just mechanic tradition—it’s critical for safety:
- Ensures even pressure distribution across the wheel
- Prevents warping of the brake rotor
- Helps the wheel seat properly on the hub
- Reduces the chance of lug nuts loosening over time
Tightening in a circle (going from one lug to the adjacent one) can cause the wheel to mount unevenly and lead to vibration or failure.
What About Torque for Spare Tire Mounting?
Your RAM 2500’s spare tire needs proper torquing too:
- Use the same torque specification as your regular wheels
- Many owners overlook proper torquing of the spare
- Check spare tire torque annually
- Consider using anti-seize on spare tire hardware as it’s exposed to the elements
Properly maintaining your spare ensures it’s ready when you need it.
Common Torque-Related Issues RAM 2500 Owners Face
Several common problems can occur related to wheel torque on RAM 2500 trucks:
- Lug Nut Seizing: Common in areas with road salt
- Stud Failure: Can result from repeated over-torquing
