Do wheels have measurements stamped on them?

Many Wheels have measurement information marked on them. If you can find and understand the markings, you won't have to measure them yourself.

How to Find the Markings

Wheel markings can be found on the backside of the hub or spokes. Sometimes they can also be found on the inside edge of the rim.

1. Remove the wheel.
2. Clean the wheel.
3. Place the wheel face down.
4. Inspect for any markings.

If your wheel is marked, you could find the Brand, Model, Part Number, Load Rating, and markings that might look like this:

7J x 16 H2 5/120 ET47

What the Markings Mean

**Click the blue links for more information.**

7 = Wheel Width

J = Bead Profile

• This is the size and shape of the lip where the tire bead is mounted. "J" is the most common and is used on most passenger cars.

x = Wheel Construction

• In this case, "x" means the wheel was constructed in one piece.

16 = Wheel Diameter

H2 = Wheel Flange

• The flange is a bulge on the surface where the tire bead is mounted. This bulge helps prevent the tire from falling into the wheel.
• The letter and number combinations specify the type, size, and shape of the flange.

5/120 = Bolt Pattern

• The first number is the number of bolts or lugs. The number following the slash is the size of the imaginary circle formed by the center of the bolt holes in the wheel.

ET47 = Offset

• In this example, the wheel has a positive offset of 47mm.

Notes

• The combination of letters and numbers used in this example are ONLY an example.
• The markings on your wheels may be split up into multiple locations.
• There is no industry standard on location or format of wheel markings.
