How to Measure Bike Tire Size

  • Your bike tire size isn’t just a number on a spec sheet or the tire’s sidewall, it’s an important part of your bike setup. Your tire’s diameter and width play a big role in how your bike handles and feels, how fast it rolls, and how well it grips the road or trail underneath. It’s an important bit of info to know, especially when it comes time to replace your tires, or if you’re looking to test out different sizing.To get more news about Carbon Wheels, you can visit official website.

    Generally, the larger the tire and wheel is in diameter, the faster you’ll roll, and the easier it’ll be to roll over obstacles. But smaller wheels may be preferred by some for height or maneuverability reasons. Similarly, the narrower the tire, the faster it rolls—plus it’s lighter—while a wider tire will offer greater traction and stability. Below, we explain bike tire sizes, tire styles, rider height, and more. Bike tires come in all sorts of sizes, but it should be really, really easy to determine the size of yours. If you’re looking to purchase a replacement tire, simply look along the sidewall of your current tire (check both sides). You’ll see something printed like “700x25mm” or “29x2.30”—that’s your tire size.

    You’ll also see the make and model of the tire, along with the recommended psi range for inflating your tire. Knowing how to measure your bike tire size is handy, but technically you shouldn’t need to measure anything in most circumstances because sizing is printed right on the tire. The first number refers to the diameter of your tire. The “700” that you will commonly see as the first number—especially on road bikes, gravel bikes, fixies, and more—denotes a 700-millimeter wide diameter tire. Another somewhat common size is 650mm, which is typically found on smaller adult bikes. Accordingly, the second number refers to the metric width of the tire.

    Common widths for metric-based bike tires run anywhere from 23mm to as much as 48mm, or even more as gravel tires get increasingly wider. Furthermore, you may see metric sizing listed as 700c or 650b. This is the older standard for sizing, where different letters represented different tire bead seat diameters. You will also see ISO sizing for tires, which is a more precise measurement for the tire bead seat diameter, though you usually won’t need to worry about it when picking out tires. For example, the ISO size of 622 corresponds with 700-size tires.
