How To Measure Bike Wheel Size (With Pictures

Let's say you measure a rim diameter of 622mm and a tire width of 39mm. We will have 39-700. 700 is the wheel diameter measured from the tire's outer edge from side to side. It is calculated by the length of the rim radius of 622 plus the tire width of 38 times 2, which equals 78; we will have a wheel diameter of 700 Lay your measuring tape or ruler across the rim from one side to the other. Get the largest measurement, between two points directly opposite one another. Slide one end of the tape back and forth along the rim until the measurement is largest. Measure across a few different diameters and take the average, in case the rim isn't quite round

How To Measure Bicycle Wheel & Tire Size

Measure from the contact point of the tire and the ground to the center point of the bike wheel and to the tire's outer edge in the opposite direction. There is another way to measure the outer diameter. Measure the distance between the contact point of the tire and the ground to the center part of the wheel. Multiply the result by two Wheel diameter = (rim diameter) + (tire diameter * 2). Wheel circumference = Wheel diameter * PI. Since the tire wraps around your rim, the wheel diameter includes the tire on both sides (thus the multiplication by 2). BikeCalc takes this view When measuring for the Actual Diameter, you will want to measure from the inside of the Barrel of the wheel (Shown by the Red Line in the above photo). Example: A wheel with an actual Diameter of 18 will have an overall diameter of around 19.5 Most bikes, whether road or mountain, are now measured in metric units, but you may find some manufacturers that still size mountain bikes in inches. Some brands, such as Moots, even mix the two Measure from any bolt to the outside edge of a bolt on the opposite side for a 5-lug rim. A wheel with 5 lugs won't have a symmetrical set of bolts. To measure a 5-lug rim, place the hook of your measuring tape in the middle of a bolt. Then, choose 1 of the 2 bolts on the opposite side
