Bridgestone designs tire that never goes flat

According to The Asahi Shimbun, Bridgestone, a byword in tire manufacturing, has developed what every car owner dreams of: a tire that doesn’t puncture. 
Dubbed Airfree and still in the developmental stage, the tire will not fit all types of vehicles, however.
It relies on plastic spokes between the rubber on the tire’s surface and the metal wheel rim. The 1-centimeter-thick spokes are designed to cushion shocks from the road surface in place of a traditional inner air tube.
An obvious benefit is that there is no risk of getting a flat, nor need to check on tire air pressure and other maintenance concerns.
Initially, Airfree will be aimed at buses and other vehicles that crawl along. Bridgestone Corp. plans to market the tire in 2026.
The company envisions the tires being fitted to community buses that many communities, especially in rural areas, operate for residents and tourists. Small electric buses that travel at under 20 kph are also in the company’s sights.
