Demystifying the Mysterious 700c Tire Size: Separating Fact from Fiction
As a cycling enthusiast, you’ve likely encountered the term “700c” when researching bike tires. But have you ever stopped to think about what this size actually means? Unfortunately, many cyclists are misinformed about the 700c tire size, thinking it refers to the actual diameter of the tire. In reality, the “700c” designation is more complex than that.
The Origins of the 700c Tire Size
The 700c tire size is a relic from the early days of cycling, when tire sizes were measured in inches. In the late 19th century, tire manufacturers used a system called the “French system,” where tire diameters were expressed in millimeters. However, this system was later replaced by the “English system,” which used inches to measure tire diameters.
When the English system was adopted, tire manufacturers needed a way to convert the French system measurements to inches. This is where the “700c” designation comes in. The “700” refers to the diameter of the tire in millimeters (700 mm), while the “c” stands for “centimetre,” indicating that the tire is designed to fit on a wheel with a rim width of 32-35 mm (approximately 1 1/4 inches).

So, what does this mean for modern cyclists? In reality, the 700c tire size is not a fixed diameter, but rather a range of diameters that can fit on a wheel with a rim width of 32-35 mm. This range can vary depending on the specific tire model and manufacturer.
To illustrate this point, let’s consider a few examples:
- The Continental Grand Prix 4000 S II tire has a nominal diameter of 700x23c, which means it’s designed to fit on a wheel with a rim width of 32-35 mm. However, the actual diameter of this tire is approximately 622 mm (24.49 inches).
- The Schwalbe One tire, on the other hand, has a nominal diameter of 700x28c, which means it’s designed to fit on a wheel with a rim width of 32-35 mm. However, the actual diameter of this tire is approximately 622 mm (24.49 inches), just like the Continental tire.
The Importance of Nominal vs. Actual Diameter
As you can see, the actual diameter of a 700c tire can vary significantly depending on the manufacturer and model. This is where the concept of “nominal diameter” comes in.
Nominal diameter refers to the intended or standard diameter of a tire, while actual diameter refers to the actual diameter of the tire. In the case of 700c tires, the nominal diameter is 622 mm (24.49 inches), but the actual diameter can vary depending on the manufacturer and model.
Real-World Implications of the 700c Tire Size
So, what does this mean for cyclists in the real world? In reality, the 700c tire size is not as straightforward as it seems. Here are a few scenarios to consider:
