What does 700 32c mean on a tire?
Typical road bike tire: 700 x 32c indicates a tire that has an outer diameter of 700mm and a width of 32mm. Note that the c does not stand for centimeters; it’s a holdover from an old French system that designated tire sizes using the letters a, b and c. The term “700c” is the tire size according to the French system. The “700” is stating the diameter of the bicycle tire and “c” is the width size of the tire. However it’s not 700 millimeters it’s 633 millimeters. Also, another common mistake is that often riders confuse “c” with centimeters.The size of a road bike tire is normally shown as the wheel diameter alongside the tire width – e. In this example, 28c refers to the tire being 28mm wide. Dimensions are printed clearly on the sidewall of the tire.A: 700x23C & 700x28C are the same tire sizes (diameter). The 23 & 28 denote different tire widths, not tire diameter. Both of these will fit the same diameter rim (700).
What is the 3% rule for tires?
The 3% rule says that your new tire’s total outside diameter should not change by more than ±3% compared to your current tire. If the increase or decrease is bigger than 3%, you risk problems like: Tire rubbing the frame or fork. Wrong speedometer reading (for road vehicles) The Rule of 105 states that the rim must be at least 105% the width of the tire if you have any chance of re-capturing airflow from the tire and controlling it or smoothing it. One of the most interesting aspects of the Rule of 105 is that before 2001, nobody was tunnel testing with 21 or 23mm tires.The 105% rule says that the external rim width of your wheel should be at least 105% of your tire’s actual measured width. This ratio allows the airflow to remain attached as it moves from the tire onto the rim, reducing drag and making your bike more aerodynamic.
What is the 3% tire rule?

What is the best rim width for 32mm tires?

What size tires can I put on a 700C rim?
