May I ask if 7 00R16 is a tubeless representation method If not, how should a tubeless be indicated?

Hello! Tubeless.

It's what we often call tubeless tires.

i.e. radial tires.

At present, passenger car tires (cars, SUVs, etc.) are basically radial tires.

Usually, the identification of car tire specifications is**r**, and the part is a number. (e.g. 205 55R16).

In general, the tires of cars belong to vacuum tires, and the difference is:

Our so-called vacuum tires are not a combination of inner and outer tubes, only outer tires and wheels, they are directly connected and sealed, should be no inner tube, and the material of the outer tire is relatively thick, so the general nail leakage time will be longer, sometimes the leakage of the whole month can also be used, but if the burst is more severe, it is generally difficult to repair (to replace).

The general tire is a combination of inner and outer tires and wheels, and now the car has no such structure (basically very little), this structure is nailed with a very piece of air leakage, and the inner tube is generally cheaper to be removed and repaired, but it is not more durable than the vacuum.

The size of the tires is 205 55 R1691V

205 – refers to a tire width of 205mm.

55 - refers to the tire flat ratio, that is, the section height is 55% of the width.

r - refers to the tire is a radial tire (the inner layer of this tire is made of radial tires)16 - means that the rim diameter is 16 inches.

91 - refers to the load index 91, which means that the maximum load of this tire is 615 kg, and the four tires are 615 4 = 2460 kg.

v – refers to a speed level of 240 km/h.

The meaning of each number.

1. It means that the width of the tire section is 7 inches.

2. R represents that the tire is a radial structure.

Indicates that the tire is suitable for a rim diameter of 16 inches.

There is no inner tube in the vacuum tire, and the ordinary one has, mainly to see this, which is a radial tire so it should be regarded as a vacuum tire.

Now car tires are tubeless.

Not necessarily, it depends on the configuration, some are tubeless, and some are not. Vacuum tires are tubeless pneumatic tires, also known as "low-pressure tires" and "pneumatic tires". In recent years, vacuum tires have been widely used in motorcycles, cars, buses and trucks.

Vacuum tires have high elasticity and wear resistance, and have good adhesion and heat dissipation properties.

For example: 205 55 r16

205: Cross-sectional width (mm).

55: The aspect ratio is 55%.

r:r=radial tire structure.

16: Rim diameter is 16 inches.

Tubeless usually refers to tubeless tires. Tubeless tires have an inner liner inside. The inner liner is made of synthetic rubber, which seals the compression air inside the tire (which functions as an inner tube).

Tubeless tires still have natural pressure loss under normal circumstances, so tire pressure usually needs to be measured at least once a month. To be on the safe side, it is advisable to check before long distances at high speeds. At present, tires for passenger cars (cars, SUVs, etc.) are basically tubeless tires.

Marked with TL in English.

99% of today's cars are tubeless, that is, there is no inner tube.

Just look at the air valve, the air valve is smaller than the hub valve hole is a non-vacuum tire, and the valve rubber covers the cylinder valve hole is a vacuum tire.

The most direct is to look at the valve, the tubeless is independent. The valve of the tubeless is the upper strap of the inner tube. It's obvious.

The simplest thing to look at is the air valve for inflation, if it sticks out of the steel ring, it has an inner tube, and if it is directly connected to the steel ring, it is a vacuum tire.

If it is a domestic motorcycle, there is also a convenient and quick way to distinguish, if it is a steel wire rim, it must be an inner tube, if it is a steel cast or aluminum cast rim, it must be confirmed according to the above method.

There are also very few imported car wire rims with vacuum tires, but the cost of modifying the rims is large, measured by our **, it can be worth half the car price.

Explain in detail how to distinguish a vacuum tube.

Keep it simple and take a look at the inflated valves for yourself.
