Bridgestone Develops ‘Cooling Fin’ Technology for Run-Flat Tyres
Bridgestone Corporation, has unveiled details of a new technology that is said to “expand the vehicle application potential of run-flat tyres.” The Cooling Fin design sees the manufacturer add fin shaped grooved in the sidewall, in a move to aid heat dissipation.
Heat generation is an issue when the tyre sidewall of a run-flat is placed under pressure following a loss of air pressure. It is even more apparent in tyres with a high sidewall, such as those for SUVs, which is why run-flats are largely limited to use with passenger cars.
The advancement in technology means lighter sidewall-reinforcing rubber can now be utilised – providing a greater scope for developing run-flats for larger passenger vehicles like SUVs, CUVs and minivans. The weight saving will also enhance comfort during normal driving conditions.
