This presentation is all about the latest innovation of the air -free tire concept by BRIDGESTONE, in the automobile sector. this will tell us how. If the air pressure is not appropriate or a tire is flat, you may have a problem in driving. The “Air Free Concept ” is a technology that eliminates the need for tires to be inflated with air to support the weight, using a unique structure of spokes stretching along the inner. Non-pneumatic tires (NPTs) have been introduced with a compliant cellular solid spoke component which functions as the air of the pneumatic tire. In this paper.

Airless Tires | Bridgestone Tires

Even though tyres made out of solid rubber exists, they don't have enough compliance and will not provide a supple ride if used in normal vehicles.

The NPT discussed here consists of mainly three parts. Because of the benefits, I believe that it is extremely important that research and production of airless non pneumatic tyres is continued and increased.

This type of innovation works well in conjunction with several engineering codes of ethics, and thus should be embraced by non pneumatic tyres everywhere. Cars are things that people use every day, so any improvements over existing designs would affect the lives of the majority of people.


Learning about non pneumatic tyres a topic, therefore, I believe holds extreme value- especially for us freshmen engineering students. In doing research into these kinds of topics that hold significant meaning, we can see that what we will do can make a difference.


Hence the name, tyre, as it tied the wheel together. This was then placed on wooden wheels of carts and wagons.

It had its problems as the cold weather caused it to be brittle whilst in hot weather they became sticky. However, inCharles Goodyear discovered that by adding sulphur to the non pneumatic tyres latex it gave elasticity and strength. This vulcanized rubber was used to as cushion tyres for cycles.

Another person, Robert Thomson, had already patented the idea of a pneumatic rubber tyre so the Dunlop Rubber Company was established and won a legal battle with Thomson. Non pneumatic tyresMichelin revealed the first radial tyre was developed and this was non pneumatic tyres revolutionary achievement as it used steel-belted radial tyres.

Although this prototype is still being developed, the future looks bright for this revolutionary tire. Bridgestone airless tire technology features a unique spoke structure designed to support the weight of a vehicle, effectively eliminating the need to periodically refill the tires with air. InNon pneumatic tyres revealed its second generation air free concept non-pneumatic tire featuring improved load-bearing non pneumatic tyres, environmental design and driving performance.

However, there are developments and enhancements to be made before airless tires are available for consumers. Non pneumatic tyres a way to avoid trapping debris within the spokes, as well as developing non pneumatic tyres best way to distribute weight evenly and consistently transmit loads are a couple of these hurdles.

Installation of airless tires depends on the use. Heavy equipment will need special equipment to mount but an airless bicycle tire can be mounted with little or no effort.

Solid airless lawnmower tires come pre-installed on the wheel allowing quick installation. Mobike tire Many bicycle-sharing systems use these tires to reduce maintenance.

Airless Tires

InMichelin started developing an integrated tire and wheel combination, the " Tweel " derived from "tire" and "wheel," which, non pneumatic tyres the name "Tweel" suggests, are combined into one new, fused partwhich operates entirely without air.

Michelin claims its "Tweel" has load carrying, shock absorbing, and handling characteristics that compare favorably to conventional pneumatic tires. A market roll out is therefore not planned in the near future.
