FAQs

What is the stock wheel offset on RAM 1500? ›

The factory OEM (Original Equipment Manufacturer) wheels on the Ram 1500 will have an offset between +15mm and +25mm depending on which trim package and wheel option you have.

PCD fitments are a measurement showing first the number of studs/bolt holes and secondly the distance that they are spaced out. Common ones are 4×108, 4×100, 4×114.3, 5×100 and 5×114.3.

PCD stands for Pitch Circle Diameter which basically means the diameter of an imaginary circle running through the centre of each bolt hole. The most common PCD values are 100mm and 114.3mm, the difference arising due to manufacturers using metric or imperial measurements (4.5 inches = 114.3mm).

What size rims does the RAM 1500 have? Most OE RAM 1500 rims range in diameter from 17'' to 22''. No matter which wheel size your RAM rests on, we've got the rim selection you need to customize your rig's look.

You can find offset measurement embossed at the back of the wheel. It's either on the mounting plate or on the spoke's rear. It often ends with the letters "ET," but it can also be in the beginning. So, both ET45 and 45ET mean 45 mm offset.

Wheel PCD and Offset explained: PCD is the amount of mounting holes in the wheel and the width apart of the mounting holes. Offset is the distance of the hub mounting surface to the centre line of the wheel, see below for a full explanation.

Most wheels will have their offset embossed on the back of the wheel, either on the mounting plate itself or on the back of one of the spokes.

PCD (Pitch Circle Diameter)

Is the diameter of the circle formed by the holes on your wheels in millimeters. They are usually written in the hundred or near the hundred beside the number of holes such as: 4×100, 4×120. In Japan, this number is followed by the number of holes (100-4h, 120-4h).

Bolt pattern or Pitch Circle Diameter (PCD) is the diameter of an imaginary circle formed by the centers of the wheel lugs. Bolt patterns can be 4-, 5-, 6-, or 8-lug holes. A bolt circle of 4×100 would indicate a 4-lug pattern on a circle with a diameter of 100mm.

Is PCD the same as stud pattern? ›

Pitch circle diameter(PCD) is a reference to the number of studs equally space around a circle diameter centralised on a hub face. Stud pattern is a popular term for a combination of a PCD and stud size.

RAM 1500 pickups typically come with either a 5x139. 7 or a 6x139. 7 bolt pattern, depending on the year model and trim level.

As of 2022, the bolt pattern on a Ram 1500 is 6 x 5.5 inches or 6 x 139.7 millimeters. This means the wheels of a 2022 Ram 1500 are attached to its hub using six bolts, and each bolt is placed 5.5 inches or 139.7 millimeters apart in a circle.

To ensure a set of rims fit properly on your vehicle, you'll need the hub size on your car or truck as well as the wheel center bore measurement and number of wheel studs (as well as the distance between those studs). Les Schwab has those measurements for your vehicle, including bolt patterns.

no contact or rubbing. and the tires (265/65-17) poke out the fender guards nicely. Need more info. than what you are providing but with all things equal a -12 offset wheel will stick out further than a 0 offset by about 0.47" or just about 1/2 inch.
