COM­MU­NI­CAT­ING TYRES

Car (South Africa) - - FEATURE -

We have pre­vi­ously cov­ered clever sen­sors em­bed­ded in per­for­mance tyres ca­pa­ble of send­ing in­for­ma­tion about such pa­ram­e­ters as pres­sure, tem­per­a­ture and even grip lev­els to the ve­hi­cle’s elec­tronic safety sys­tems in or­der to al­ter trac­tion con­trol, ABS and en­gine torque for op­ti­mum per­for­mance. This tech­nol­ogy is still un­der de­vel­op­ment and there­fore too ex­pen­sive for mass pro­duc­tion, but a sim­i­larly func­tional tyre chip can now be found in the new Miche­lin X Multi HD D truck tyre. This ra­dio-fre­quency iden­ti­fi­ca­tion chip weighs just 0,2 g and is built into the tyre cas­ing, where it can­not be re­moved or dam­aged. The chip is read by a scan­ning tool and car­ries a unique se­rial num­ber linked to the his­tory of the tyre, from cra­dle to grave. Mea­sured tyre depths and the like can be linked to the se­rial num­ber for trace­abil­ity. If this in­for­ma­tion is com­bined with a tyre-pres­sure sen­sor, tyre life can be linked to pres­sure which is crit­i­cal to min­imis­ing cost for fleet own­ers.
