# How To Measure Wheel Size On A Bike

### To measure a bicycle wheel start by standing the bike upright by leaning it against a wall or using the kickstand.

How to measure wheel size on a bike. If you find the tire size the first dimension is the tire diameter the second dimension is the tire thickness. If the sizes of wheels are changed the odometer or speedometer will give a wrong reading. Measure on the ground the length between the first dot and the second dot and this should give you the circumference of your bike s tire. Next multiple the radius by 2 to get the diameter.

The wheel size is based on the diameter of the tire see below and as each tire size gets larger so does the size of the bicycle frame. Take your tape measure and place it on flat surface across the tire s tread going from one side to the other side. Then use a tape measure to measure the distance from the ground underneath the tire to the center of the wheel to get the radius. These different wheel and frame sizes help companies design bicycles that will fit kids of all ages and heights.

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. In some site it suggested frame size of 18 5 47 cm size. Being that i m on the cusp of tire size charts leaving bike frame size aside at the moment can you enlighten me with the difference between 26 and 29 wheels besides the obvious. The most common sizes are.

If it is just the frame this will be the center point in the bottom bracket shell. 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. Standard bike tire sizes place the diameter first and the width second. As we will learn more later.

Measure the distance or circumstance around the outer part of the bicycle wheel to calibrate odometer or speedometer of a bicycle gps and computer. I m primarily doing trail riding with a mountain bike and i m curious if the larger diameter wheels would require less force to go over slightly bumpy. Measure the diameter of the existing tire as illustrated above d or look on the tire for the size it looks like this. Now all that s left to do is to combine the measurements.

Hi i am beginner planning to buy cycle 5 7 ft height 32 leg size which wheel base would suit me 26 or 27 5 though planning for mountain bike most my trails will be on mud and rough roads and bumpy ride. 12 inch 16 inch 20 inch and 24 inch. To measure your bike s frame size take a measuring tape and place the tape in the center bolt of your bike s cranks. Measuring the bike tire size is hard as it initially seemed.

Bike frame sizes are measured in the same way for all styles of bicycle. Record the tire diameter as this also represents the bike frame size.
