A California lawyer has filed a lawsuit demanding that Bridgestone Corp.'s US unit recall 27.5 million Steeltex tyres that allegedly suffer from tread separation similar to that which led to a massive recall two years ago, Reuters reported. Reuters said the suit seeks class action status and could cost Bridgestone/Firestone Inc. as much as $2.75 billion to recall roughly 27.5 million Steeltex R4S, R4SII and A/T tyres.
