# How To Measure A Bike Wheel Rim

### On this episode of wheel school we go over how to properly measure your wheels.

How to measure a bike wheel rim. The calculation here will give you your bike s frame size. Sometimes you might even need to know the circumference of a bicycle wheel which is also a simple determination that can be achieved in multiple ways. Therefore a 20 622 tire is a tire 20mm wide that fits on a rim with 622mm in diameter typically a road bike rim or a 29er one. Measure the diameter of the entire wheel including rim and inflated tire.

Bike frame sizes are measured in the same way for all styles of bicycle. This chart will provide guidance on what tires sizes can match your internal rim width. Step 2 locate your measurement in inches or millimeters on a bicycle tire chart and match it to the corresponding rim size. Measure the diameter of the rim in a similar manner if you only have a rim.

If it is just the frame this will be the center point in the bottom bracket shell. This should be measured through the centre from the outer edges of the tire. Measure the distance between the wheel s hub or axle assembly and the outer edge of the wheel s rim. Although measuring a bicycle wheel including determining the size of both the tire and the rim can be accomplished by either of two methods both are simple to complete.

We show you how to measure the diameter width offset and backspacing. The wheel size for a mountain bike or any other type of bike is a combined total of the rim diameter and the thickness of the tire itself. Let us know your thoughts what you would. This measurement used only if the size printed on the tire is no longer legible can be used to determine wheel size.

To measure your bike s frame size take a measuring tape and place the tape in the center bolt of your bike s cranks. If the sizes of wheels are changed the odometer or speedometer will give a wrong reading. Many mountain bikes have a 26 inch wheel again meaning the rim plus tire but you can determine for sure using one of two methods.
