### What size is a 28 in tire?

Size Designations Overview

ETRTO Inch

Tire section height Approx. 1 5/8″

#### Is a 28 inch tire the same as 700C?

The tyres can differ, but the 28”, 700C and 29er are all the exact same rim diameter. The 700 markings will be followed by the width in mm, and the 28 or 29 markings will be followed by the width in inches.

What is the circumference of a tire with a diameter of 36 in?

Calculations: The Circumference of a 36 inch tire is PI * 36 = 113.1 Inches or 9.42 feet.

What size is a 27 inch tire?

27-inch tires come in common widths of 1-1/8 inch, 1-1/4 inch, and 1-3/8 inch for some older hybrid and cycloross bikes. The BSD of 27-inch tires is 630mm. 27-inch and 700C tires are close enough in size that the inner tubes are compatible; i.e. you can use a 27-inch inner tube in a 700C tire, and vice-versa.

#### Is 27.5 the same as 28?

Oddly enough, tires with an inner diameter of 630 mm are classified as 27 inch. These classifications originate from the time of tire brakes. When the 29 inch MTB tire size was introduced a few years ago, it had the same inner diameter of 622 mm, known as 28 inch in Europe. The latest tire size is 27.5 inches.

Is 29 inch the same as 700c?

29″ (ISO size 622) is actually the same rim diameter as 700C, although most 29″ tires will not fit 700C road rims because they’re too wide. 700C (ISO size 622) is the most commonly used size for modern road bikes.

What is a 700c wheel size?

700C is used to refer to any tire, rim, or wheel with a 622mm BSD, but it could be on a skinny-tired road bike where the wheel has an actual diameter of only 660mm (which is actually a little LESS than 26 inches!), or a mountain bike with a wheel diameter of over 29 inches.

## How to calculate tire diameter and rim circumference?

The 255 is the tire width in millimeters, measured from the bottom of the bead to the bottom of the bead, the 60 is the sidewall aspect ratio (the tire width factor), the ratio of sidewall height to tire width at the tread (indicating that the sidewall height is 70% of the tread width), and the 17 is the wheel rim diameter in inches.

### How big is a 28 inch bike tire?

Both indications are, however, very imprecise. A less wide 28 inch tire, e.g. with a tire width of 23 mm, which is usual for a road bike, has in fact only an outer diameter of something more like 26 inches. In the case of a tire width of 40 mm, it is more or less correct that the outer diameter measures 28 inches.

#### How big is a 700 x 28c tire?

The calculator above is based on the ISO/ETRTO (European Tyre and Rim Technical Organization) tire size which specifies tire size as a tire width and rim circumference in mm. A ISO tire size of 28-622 is how we would refer to a 700 x 28C tire has a tire width of 28 mm and a rim diameter of 622 mm. If your wheel size isn’t listed in
