Tubeless tyres are tyres that do not have tubes within. The tyre and the rim of the wheel form an airtight container to seal the air as the tubeless tyre has an inner lining of halobutyl. The valve is directly mounted on the rim. Whereas, a tube tyre has a balloon type bladder to keep it inflated.
A Tubeless tyre can be repaired without removing it from the Car. Compared to tubed tyres, the tubeless tyres provide advantages in terms of safety and better mileage. Tubeless tyres have been in use since the last half century in many countries.
Since tube is eliminated , friction between tyre & tube is not experienced, thus lower resistance, less vibrations , less heat generation and better comfort. Also, chances of Tyre tube getting pinched under the bead while mounting are eliminated & the number of components used in a tyre wheel assembly gets reduced.
If a tubeless tyre gets punctured, air escapes only through the hole created by the nail, thus giving substantial time between a puncture and a flat tyre. The tyre wheel assembly continues to perform its function for some time before going flat. This is one of the biggest advantages of a tubeless tyre. However, if there is a sharp penetration in a tube tyre, the air in the tube starts leaking suddenly in all directions. This causes the wheel assembly to loose stability thereby resulting in accidents.
1. Better Safety
2. Better fuel efficiency
3. Cost saving on tube
4. Less chance of damage in case of flat running
5. Better heat dissipation
6. No tube related problems
7. Less balance weight required
Today in India, almost all Cars such as the Honda Accord, Honda City ,Opel Vectra, the full Mercedes range, Chevrolet Optra, Honda Civic, Ford Ikon and Toyota Qualis all use
Tubeless tyres .
