* Bolt Pattern (PCD): This is usually expressed as a number like 5x135 or 8x170, indicating the number of lug nuts and the diameter of the circle they form.
* Wheel Stud Diameter: This is the diameter of the studs that the lug nuts screw onto.
* Lug Nut Size: This specifies the thread size and length of the lug nuts.
You can find this information:
* On the vehicle's driver's side doorjamb sticker (often): Sometimes the sticker will list wheel specs.
* In the owner's manual (if you have it): The owner's manual will have the specifications for your vehicle's original wheels and tires.
* On the wheel itself (sometimes): The wheel may be stamped with its bolt pattern and other specs.
* Using online databases or parts websites: Enter the year, make, and model of your trucks into a parts website like AutoZone, Advance Auto Parts, or RockAuto. Search for wheels or lug nuts for each truck and it will often list the specs.
Don't assume they're the same; always verify. Using the wrong bolt pattern is extremely dangerous and can lead to wheel failure.
