Ever wonder what the tires of the future will be like?

Some may not even have air

Apart from introducing its latest Ecopia line of tires and giving us an in-depth look into these green tires\' characteristics, Bridgestone has also revealed two tire concepts that further push the boundaries for environment-friendly and sustainable rubber.

The first is the Large & Narrow Concept, whose 155/55 R19 specifications are true to the name. It is designed to have a bigger contact patch by length rather than by width. The combination of a long contact patch and increased internal air pressure prevents \"water from accumulating between the tire and the road,\" while the use of grip-enhancing compounds and tread patterns also contributes to wet-weather performance.

That said, the main advantage of the tire\'s being tall and skinny is a rolling resistance coefficient \"that is approximately 30% lower than [those of] conventional-size tires (175/65 R15).\" In our recent eco-tire feature story, we discussed how this directly contributes to better fuel consumption.

The other development tire is the non-pneumatic Air-Free Concept. As with the Large & Narrow, this one is also what its moniker suggests, with an internal structure composed of thermoplastic-resin spokes in an interlaced structure. There is \"no need to periodically refill [this tire] with air,\" according to Bridgestone, so it \"requires less maintenance\" and \"the worry of punctures is eliminated.\" Moreover, the Air-Free is 100% recyclable.

The Japanese tiremaker does concede that these \"next-generation\" rollers are quite a long way down the road; we\'re talking about generation in the human, not automotive, sense. Still, these tires of the future make you wonder what the cars of the future will be like, don\'t they?
