Before determining the right tire size for your bicycle, it’s helpful to know how to measure bike wheel size. First, you’ll need to determine the tire width. It can vary from side to side, so this measurement is essential.
Then, you’ll need to know the diameter of your bicycle’s rim. The ISO system lists the tire’s width first, followed by its diameter.
To calculate the exact diameter of your bicycle’s tires, you’ll need to know the tire’s circumference.
To get an exact measurement, you’ll need to know the diameter of the bike’s wheel. It’s important to know this measurement because it can vary greatly from one bike to the next. The average diameter of an adult bicycle wheel is between 26 and 29 inches.
You can determine the size of your wheel by checking the sidewall of the mounted tire. By using the measurements of your bicycle’s wheel, you’ll have the exact size you need to purchase new tires.
To measure the wheel’s diameter, you’ll need to stand upright and position the bicycle on a kickstand. You want to make sure the bike is stable and not tipping over while you’re measuring. You’ll also need a measuring tape.
A retractable metal tape measure will save you time and allow you to use one hand while measuring your bike’s diameter. A retractable tape measure will provide you with a better grip.
