At one time, all car tires had a tube in their design. But then they began to install an improved version of the product on the wheels - a tubeless tire. Due to its special structure, it has much better characteristics.
A few words about marking
Let's start with the fact that there are no obvious external differences between the samples of both types. Therefore, in order to understand which tire is in front of your eyes, it makes sense to look for the markings. Manufacturers apply it to the side of the product. The marking can be represented by a complete inscription or only letters. On a tubeless tire, you may find “TUBELESS”, “TL” or “T”. On the chamber - "TUBE TYPE", or in short - "TT".
However, there may not be any mark on the tube tire. Most likely, this indicates that it was made back in the days when the tubeless version did not exist, and therefore there was no need for marking.
What is the main difference between a tubeless tire and a tube tire is clear from the very names of these products. The tube tire is compound. If it is mounted on a wheel, we can only see its tire. Under this upper rubber layer is a separate part - the chamber. Inflated, it looks like an elastic tube, closed in a ring. It is the chamber that determines the elasticity of such a tire.
The tubeless tire, in turn, is one-piece. Why does it hold its shape and does not deflate? It's all about the features of its attachment to the rim of the rim. The fit in this case is so tight that air leakage is absolutely excluded. An important role here is played by the device of the landing bead of the tire, and the design features of the rim itself. The figure shows the structure of two types of tires:
The sealing layer is of exceptional importance in the structure of a tubeless tire. It has the property of enveloping a sharp object in the event of a puncture. Therefore, in such a situation, the tire does not deflate immediately, and the car can continue to move safely for some time.
If a tube tire is punctured, it deflates instantly. This is because air escapes not only through the damaged area, as in the case of a tubeless tire, but also between the edges of the tire and the rim of the disc, where the connection is not tight.
It should be noted that in many cases, a defect in a tubeless tire can be quickly repaired with a suitable paste without having to dismantle it. At the same time, even minor damage to a tube tire is a big hassle.
What is the difference between a tubeless tire and a tube tire, if we compare the terms of their service? And here the comparison will not be in favor of the tube tire. It wears out faster due to the strong heating when the wheel rotates. The fault is the friction of the chamber on the inner surface of the tire.
Moreover, an increase in the air temperature in the tire leads to an increase in the internal pressure. And if the latter reaches a critical value, there is a risk of rupture of the chamber. This is especially the case when the vehicle is traveling at high speeds in hot weather. As for the tubeless tire, heat transfer from it to the rim is much more efficient due to the absence of additional internal friction.
On top of that, the tubeless is relatively lightweight. This means that the load on the suspension and hubs from it is significantly less than that experienced by the parts of a vehicle equipped with tubular tires.
|Tubeless Tire||Tube Tire|
|One-piece, without tube||Composite, with tube|
|Tire-to-rim sealed||Leaky tire-rim joint|
|In the event of a puncture, it does not blow off sharply||Quickly loses air upon a puncture|
|Easier to repair the damage||When repairing requires dismantling|
|Lasts longer||Wears faster|
