Mak­ing power on the turn

The Witness - Wheels - - MOTORING -

TWO con­cept tyres that were un­veiled by Goodyear at the re­cent Geneva In­ter­na­tional Mo­tor Show prom­ise to cre­ate elec­tric­ity and ad­just the tyre pres­sure to suit the road.

The power-mak­ing tyre is called the BHO3 and could, ac­cord­ing to Goodyear, charge the bat­ter­ies of elec­tric cars by trans­form­ing the heat gen­er­ated by the rolling tyre into elec­tri­cal en­ergy. This tyre gen­er­ates elec­tric­ity through the ac­tion of ma­te­ri­als in the tyre that cap­ture and trans­form the en­ergy cre­ated by heat when it flexes as it rolls dur­ing nor­mal driv­ing con­di­tions. The ma­te­ri­als used would op­ti­mise the tyre’s elec­tric­ity gen­er­a­tion ca­pa­bil­i­ties as well as its rolling re­sis­tance.

As de­mand for elec­tric cars grows, this tech­nol­ogy has the po­ten­tial to con­trib­ute sig­nif­i­cantly to the so­lu­tion of fu­ture mo­bil­ity chal­lenges and could elim­i­nate the ve­hi­cle-range anx­i­ety mo­torists may have with elec­tric cars.

The self-ad­just­ing con­cept tyre is called the Triple Tube, thanks to three tubes that ad­just tyre in­fla­tion pres­sure in re­sponse to chang­ing road con­di­tions to en­sure op­ti­mum grip in all con­di­tions.

The tyre re­lies on an in­ter­nal pump that moves air from the main air cham­ber to the three in­di­vid­ual air cham­bers or tubes. “Th­ese con­cept tyres reimag­ine the role that tyres may play in the fu­ture,” said Joe Zekoski, Goodyear’s se­nior vice pres­i­dent and chief tech­ni­cal of­fi­cer. “We en­vi­sion a fu­ture in which our prod­ucts be­come more in­te­grated with the ve­hi­cle and the con­sumer, more en­vi­ron­men­tally friendly and more ver­sa­tile.”

Although the two tyres are con­cepts, Zekoski said they rep­re­sent a vi­tal as­pect of Goodyear’s in­no­va­tion strat­egy.
