Wheel Measurement: Everything You Need To Know About It

Wheel Measurement: Everything You Need To Know About It

If you’re like me, you’ve spent hours scouring the internet for information on how to measure your wheels. I mean, who doesn’t want to know their wheel diameter? Well, it turns out there’s a lot more to measuring a wheel than just looking at it and saying “that’s about 26 inches around,” which is what most people do. In fact, there are several different ways of measuring your wheels for performance purposes—and knowing about each one could help you make better buying decisions when shopping for new parts or going into races. So let’s dive in!

Why do I need to know my wheel diameter?

You may have heard the term “wheel diameter” before, but you might not be sure why it’s important to know or how it affects your ride. Wheel diameter is a standard measurement that can be used to determine wheel size and width, which in turn affects the performance of your bicycle.

Diameter is measured in inches and refers to the distance across a circle at its widest point–in other words, its circumference (or perimeter). As such, it can also be thought of as being somewhat analogous to radius: The larger your wheel diameter is compared with another bike’s or rider’s own personal preferences (and ability!), the greater traction will be available for stopping quickly or accelerating quickly on wet roads due to increased surface area contact between tires/rims and pavement surfaces; however this extra traction comes at cost since higher-volume tires tend towards lower rolling resistance than smaller ones so riders who prefer lighter bikes may opt for less expensive options instead!

Measurements used for standard wheels.

  • Wheel diameter: The distance from one side of a wheel’s outer rim to the other.
  • Wheel width: The wheel measurement from one mounting surface (usually hub) to another, at 90 degrees from centerline.
  • Offset: Distance between axle centerline and wheel mounting surface, measured perpendicular to centerline. This is important for tire-to-brake clearance as well as handling characteristics.
  • Center bore: Diameter through which bolt circle passes when mounting hub/lug nuts on vehicle; also referred to as “hub size.”

How do you measure your wheels?

To measure your wheels, you’ll need to know several things:

wheel measurement

  • The diameter of the wheel. This is the distance across from one edge to another.
  • The width of your wheel (or rim). This is measured between two parallel sides of an object, including their points and curves if applicable. For example, if you have an 18″ rim that has been bent outwards so it’s wider than normal (a “stretched” rim), then its width would be measured at its widest point rather than where it was originally designed to sit on an axle or hub mount.
  • Offset refers to how far in front or behind centerline each spoke sits relative to one another when viewed from above without any bends or twists in them yet accounted for; this measurement has no relation whatsoever with how many spokes there are per side but rather just indicates whether they’re staggered left/right or not so much as seen through their position relative/rotation around centerline axis line which runs straight down through center bore hole located right beneath middle part between outer edges where two different sized holes meet together forming circle shape opening hole accessible only through removing dust cap covering entire area beneath surface level.


As you can see, wheel measurements are an important part of your car. Knowing the diameter and width of your tires is crucial for safety reasons, as well as just being able to find the right size replacements when needed.
