2004 all wheel drive Toyota Sienna wears tires down to metal cords on inside edges were extremely chopped at 11,000 miles and worn to metal by the time Toyota replaced at 23,000 this is not a safe condition ,no one can expect to see seperated tire cords at 23,000 on ant production vehicle,,vehicle came with dunlops dsst 22560-17 and were replaced with bridgestone b380 runflats at Toyotas expense . However this is a desiegn flaw in our opinion ,does the all wheel drive push and pull on suspension causing tire wear???,,we feels Toyota needs to retofit suspension or come up with a runflat tire that can have normal wear.
