## What is the circumference of a road bike wheel?

Please note this table is only a guideline and by no means complete or 100% accurate as wheel circumference can vary due to tire pressure, tread selection, tire thickness, rider weight, rim width, and load….Wheel Circumference Setting.

Size | ISO | Circumference (mm) |
---|---|---|

700×25 | 25-622 | 2105 |

700×28 | 28-622 | 2136 |

700×32 | 32-622 | 2155 |

700×35 | 35-622 | 2168 |

### What is the circumference of a 700x25c bike tire?

Tire circumference reference table

ETRTO | Tire Size | Circum- ference (mm) |
---|---|---|

20-622 | 700x20C | 2086 |

23-622 | 700x23C | 2096 |

25-622 | 700x25C | 2105 |

28-622 | 700x28C | 2136 |

#### What does 700x23C mean?

700x23c simply means the dimensions of your bike tire, under what’s known as the ‘French system’. The first number, 700, refers to the nominal diameter of the bike tire and is measured using millimeters. The second number, 23, is actually the width of the bike tire, again it’s measured in millimeters.

**Is 27.5 the same as 700c?**

Just as a 700C wheel is the same diameter as a 29” (29er) wheel, 650B shares the exact same rim diameter as 27.5”. 27.5”/650B rims have a bead seat diameter of 584mm, and 29”/700C rims have a bead seat diameter of 622mm.

**How do you calculate the circumference of a wheel?**

Calculate the circumference of the wheel. Use the formula: c = 2_pi_r, where c is the circumference, r is the radius, and pi can be approximated by 3.14. Following the example, if the car wheel has a radius of 0.3 meters, then the circumference is equal to:

## What is the circumference of a bicycle wheel?

Take a look at your rear wheel. The circumference of the rear wheel (including the tire) on an average road bike is roughly 82 inches (6 feet, 10 inches) or about 2.1 meters (rounded to 1 decimal place). How close it is to 2.1 meters on your bike depends on things like the tire you’re using and how inflated it is.

### What is the wheel size of an adult bike?

Small-wheel bicycles are adult bicycles that have wheels of 20 inch nominal diameter or less, which is smaller than the 26″, 27.5″, 29″ or 700c sizes common on most full-sized adult bikes.

#### What is the circumference of a car tire?

A common car tire is nearly 30″ in diameter. Its circumference is its diameter times pi. Let’s round everything a little for simplicity and say that its circumference is 90″ (that’s actually pretty close). One mile is 5280 feet, or 63,360 inches.
