700c refers to: the outer diameter of the tire.
25 refers to the width of the cross section of the tire is 25mm.
Tyre specifications. Tire circumference (unit: mm).
700*32c
The tire circumference is 2174mm
If you want to guide the diameter, you can divide it by 2174.

700*32c
700*35c
700*40c
Divide the circumference by pi to get the diameter. (Corrected by MCLUS Hero) like 26 "car is: 26". 4mm
That is, the outer diameter of the tire (not the circumference, but the diameter) of the car is larger than that of a 26" tire. It is generally used in sports cars, for example.

The length unit is converted, the original unit is the bicycle tire, the target unit is mm, and the base system is, calculate how many mm the bicycle tire of 32c is equal to:
32c \times
32c for bicycle tires equals:
-
1 full amount,,700*32C itself is the international standard size marking,,, 700 refers to your wheel diameter is 700C wheel, the amount of this 700 actually does not mean that the actual diameter of the wheel is 700mm,,, is a size level on behalf of, is only between 650C and 27 inches of wheel size, the diameter is about 670mm, 32 fingers of the tire width, 32mm
-
700*32c itself is an international standard size marking, c refers to the first two numbers in millimeters, 700 refers to the diameter of the rim is 700 mm, and 32 refers to the cross-sectional width of the tire is 32mm.
In general, road tires have an air pressure of 60-80 psi, which is a weight-bearing situation, and the reference circumference of the tire is 2174 mm.

It is 23 inches.
Bicycle Introduction:
1. Bicycle, introduced to China from Western countries, also known as bicycles or bicycles, is usually a small two-wheeled land vehicle. Now bicycles are all over the world, entering every household, and are the most common means of transportation for people.
After people ride on the car, they are powered by pedals, which is a green and environmentally friendly means of transportation.
2. The bi of the English bicycle or bicycle means two, and the cycle means the wheel. In Japan, it is called "self-car"; In Chinese mainland, Hong Kong, Macau, Taiwan, Singapore, it is usually called "bicycle" or "bicycle"; In Hong Kong and Macau, it is often referred to as a "bicycle". It was first invented by Drèss (1785-1851), a forester in Germany.
There are single bikes, as well as tandem or multi-person bikes.
3. It can be used as an environmentally friendly means of transportation for transportation and travel; More and more people use bicycles as fitness equipment for cycling exercise and bicycle travel; Cycling itself is also a competitive sport, there are road cycling, mountain biking, track cycling, stunt cycling, etc.
Tires: Tires: Soft tires and hard tires.
The soft-side tire section is wide, which can fully wrap the inner tube, and the landing area is relatively large, which can be suitable for driving on a variety of roads. The hard-sided tires have light weight, small landing area, and are suitable for driving on flat roads, and have the advantages of low resistance and light driving. The pattern on the outer tire is to increase the friction with the ground.
The width of the tires on mountain bikes is particularly wide, and the pattern is deep, which is also suitable for off-road mountain use.
First of all, it depends on what brand of tires you use, just my tire Magis. >>>More
There are several possible reasons why a bicycle tire is leaking where it has been repaired: >>>More
It does not matter. The speed of a bicycle is not determined solely by the size of the wheel, but by the ratio of the size of the wheel to the sprocket. Let's go into more detail : >>>More
You're right, don't care what everyone says.
Rolling is a compound motion of translation and rotation, therefore, when judging by the composite mode, the direction of friction caused by translation is opposite to the direction of rolling; The direction of the frictional force caused by the rotational action is the same as the direction of rolling. The rear wheel of the bicycle is a compound motion caused by turning, so the direction of friction is the same as the direction of rolling; The front wheel is a compound motion caused by translational motion, so the direction of friction is opposite to the direction of rolling. When not pedaling, due to inertia, the two wheels still maintain their original motion state. >>>More
Ways to keep your bike from getting punctured:
1. The use of puncture-proof tires can effectively prevent the damage of small objects such as glass ballast to the tires. >>>More
