The lug pattern, also known as the bolt pattern or wheel stud pattern, is a crucial specification when choosing replacement wheels for your 2012 Ram 1500. Getting this wrong can be dangerous and lead to wheel failure. This guide will clarify the lug pattern for your 2012 Ram 1500 and answer frequently asked questions.
What is the Lug Pattern for a 2012 Ram 1500?
The 2012 Ram 1500 typically uses a 5x150mm (5x6 inch) lug pattern. This means it has five lug bolts arranged in a circle with a diameter of 150 millimeters (or 6 inches). However, it's crucial to verify this with your vehicle's owner's manual or the sticker located on the driver's side doorjamb. Some models or trim levels might have different specifications, particularly if they came with optional wheel packages.
What Does 5x150mm Mean?
The "5" refers to the number of lug bolts or studs. The "150mm" (or 6 inches) represents the diameter of the circle formed by the centers of the lug bolt holes. This measurement is critical for ensuring the wheel fits properly and securely on your vehicle's hub. Using an incompatible lug pattern can result in a dangerous and potentially catastrophic situation.
What is the Difference Between 5x150mm and 6x139.7mm?
The numbers represent different lug patterns. The 5x150mm pattern is common on many Ram trucks, while 6x139.7mm is another frequently encountered pattern, but for different vehicle makes and models. Using a wheel with the wrong bolt pattern is unsafe and will not fit correctly. Mixing and matching patterns is extremely dangerous.
What Other Wheel Specifications Should I Consider?
Beyond the lug pattern, you need to ensure several other specifications match your existing wheels to ensure a safe and proper fit:
- Wheel Diameter: This is the overall diameter of the wheel, measured in inches. (e.g., 17", 18", 20").
- Wheel Width: Measured in inches, this specifies the width of the wheel rim.
- Bolt Circle Diameter (BCD): This is another term for lug pattern, so make sure it matches the 5x150mm.
- Offset: This is the distance between the mounting surface of the wheel and the center line of the wheel. Incorrect offset can affect handling and clearance.
- Center Bore: The diameter of the center hole in the wheel. This must be large enough to fit over the hub of your vehicle.
Where Can I Find My 2012 Ram 1500's Lug Pattern?
The most reliable sources for verifying your lug pattern are:
- Your Owner's Manual: This is the definitive guide to your vehicle's specifications.
- The Sticker on the Driver's Side Doorjamb: This sticker usually lists tire size and other vital information, including the lug pattern.
- Your Existing Wheels: The lug pattern is often cast into the wheel itself.
Can I Use Different Wheels on My 2012 Ram 1500?
You can use different wheels, but only if they meet the same specifications as your original wheels (5x150mm lug pattern, correct diameter, width, offset, and center bore). Using wheels with different specifications is extremely dangerous and can lead to wheel separation.
