For a mountain bike with a wheel diameter of 27 5 inches, what is the value of the tire circumferenc

It should be inches, not inches.

1 inch = mm, so the circumference is : = mm meter sets the value of the tire circumference is mm.

The unit of wheel diameter is inches, not inches, and one inch is equal to millimeters.

The value of the tire circumference set by the computer also depends on the specific tire width.

For example, the tire circumference can be set to 2150mm; The wheel diameter specification can be set to 2079mm; If the wheel diameter is specified, it can be set to 2182mm.

Bicycles are electronic devices used to calculate mileage and speed. It consists of an induction magnet mounted on the steel bar of the front rim, a sensor on the front, a computer base on the grip along the connecting wire, and a computer on the base.

The working principle of the computer is: when the rim rotates, the sensor captures the information brought by the induction magnet, transmits it to the computer through the sensing line, and the host computer calculates the information such as speed and mileage after processing it.

1 inch = cm = mm, inch = mm, inch is the diameter of the wheel, circumference = vulr = mm.

Tested it myself, rolled around the ground with a wheel, and it was 2140 That's right.

Here is the diameter of the rim and the width of the tyres.

The diameter of the rim becomes larger when the rim is added to the outer tires.

We can go back to a table to find out that the circumference of the wheels with the 26-inch rim plus the outer tires is: 2055 mm.

Then the diameter of the inch is more than 26 inches:

Then the wheel circumference is: (2055 mm.)

The measurement is 2140 and can be used for computer data.

Here is the diameter of the rim and the width of the tyres.

The diameter of the rim will become larger after the rim is added to the outer tires, and we can find out that the circumference of the wheels after the 26-inch rim plus the outer tires is 2055 mm.

Then the diameter of the inch is more than 26 inches:

Then the wheel circumference is: (2055 mm.)

is 2055 mm.

The circumference of a car tire is generally as follows:

There will usually be 185 65 r14; 185/65 r15；205 55 R16 three.

Example of tire size specifications (take 195 55R15 as an example:).

195: Section width, that is, the area where the tire can be grounded, in millimeters.

55: Tire flattening rate, that is, the ratio of tire section height to section width.

R: Construction mark, R is the abbreviation of radial tires. Bias tires are represented by the English letter "b". Tires for cars are generally radial tires.

15: The inner diameter of the tire, that is, the diameter of the hub, is generally measured in inches.

Consumers can find a variety of numbers and letters on the tires of their cars, which represent some basic data about the tires. Take a 185 60 R14 tire as an example, where 185 represents the cross-sectional width of the tire, that is, the tire ground contact area, in millimeters; And 60 represents the flat ratio of the tire, that is, the ratio of the height of the tire to the width of the tire; r is the construction mark of the tire, which is the abbreviation of radial tire; The last 14 indicates the diameter of the tire's hub, in inches.

The tires are also marked with the letter speed class, which indicates the maximum speed at which the tire can carry a specified load under specified conditions. The letters A to Z represent the certified speed class of the tires from km/h to 300kmh. The commonly used speed classes are as follows: Q:

160 kmh, r: 170 kmh, s: 180 kmh, h

210 kmh, V: 240 kmh, W270 kmh, etc.

Take 195 60r14 as an example: perimeter = 2 * radius.

i.e. 2*mm = meter.

Summary. Dear Hello Mountain bike tires are multiplier gauge wheel diameter should be set? The value of the tire circumference set by the pro-computer also depends on the specific tire width.

For example, the tire circumference can be set to 2150mm; The wheel diameter specification can be set to 2079mm; If the wheel diameter is specified, it can be set to 2182mm.

Dear Hello Mountain bike tires are multiplier gauge wheel diameter should be set? The value of the tire circumference set by the pro-computer also depends on the specific tire width. For example:

Wheel punch diameter specifications, tire circumference can be set to 2150mm; The wheel diameter can be set to 2079mm; If the wheel diameter specification is specified, it can be set to 2182mm

Tires for rides.

Dear Hello 2174

The measurement is 2140 and can be used for computer data.

Here is the diameter of the rim and the width of the tyres.

The diameter of the rim after the rim plus the outer tire will become larger, and the circumference of the wheel set after the 26-inch inner rim can be found through a ** Yuru plus the outer tire is: 2055 mm.

Then the diameter of the inch is more than 26 inches:

Then the circumference of the wheel is: (2055 mm.)

Bicycle tire specifications: The tire walk circumference is 2115 mm. Here is the diameter of the rim, which is the width of the outer tire, and the diameter of the rim will become larger when the rim is added to the outer tire.

The circumference of the wheels after the 26-inch rim plus the outer tire is 2055 mm, so the diameter of the inch is more than that of the 26 inches, so the circumference of the wheel is: (2055 mm.)

Bicycle classification:

There are many varieties of bicycles, which can be classified according to different methods, such as trucks, ordinary cars, light vehicles, sports cars and competition vehicles; According to the use of objects, it can be divided into men's cars, women's cars and children's cars; According to the diameter of the wheel, it can be divided into 71 cm car including noisy, 69 cm car, 66 cm car, etc., in addition to double tandem, fitness, acrobatics and other special bicycles.

The bicycle is mainly composed of the body part, the transmission part, the action part and the safety device, and some accessories can be added as needed. Bicycle accessories include hangers, brackets, air pumps, safety forks, fenders, etc. Ponji.

The body part is mainly composed of frame, fork, handlebar, saddle and fork assembly. The center distance between the front and rear wheels, the fork tilt angle, and the fork reach are the main parameters of the bike.

The transmission part consists of pedals, cranks, sprockets, bottom brackets, chains and flywheels. The cyclist's feet press the pedals to drive the crank to rotate, and the sprocket is transmitted to the flywheel on the rear axle through the chain to rotate.
