How do tubeless tyres work?

In place of the tube in a normal tyre, the tyre and the rim of the wheel form an air container in a tubeless tyre. To 'seal in the air', in this tyre-rim compartment, the inner wall of the tyre is throughly lined with an impermeable, air-tight membrane. The inner liner of the tubeless tyre is constructed of halo-butyl / chlorobutyl and other materials. This performs, in essence, the important chore of substantially reducing the permeation of air, as compared to the natural rubber inner liner, a function of which is why we use a butyl tube in a tubed tyre.

During high speed cruises, the temperature within the tyre rises significantly. This in turn increases the pressure on the tyre tube. An ordinary tyre is fairly vulnerable under such circumstances. Any protrusion into the tyre which at other times will cause a routine puncture, due to such heat, causes the tube to burst like a balloon. The air escapes fast as the only air tight component in the tyre is the tube. Sometimes the air escapes with so much force that it tears the tyre as well. This may cause the driver to lose control of the vehicle which at a high speed can be fatal. The tubeless tyre is better suited to hold air than a much thinner tube. In case of a protrusion, the air escapes only through the hole that caused the puncture, which is plugged by the very thing that caused the puncture, and hence escapes at a slow pace giving the much required safety. As tubeless tyres contain the air themselves, they provide much more efficient dissipation of heat. This is enhanced if the wheels are made of alloys rather than the conventional ones.

On an average, a tubeless tyre is lighter than a normal tube-type tyre by about 500g. This weight difference adds to the fuel economy of the vehicle.
