Was Vehicle Towed: - Description of the Complaints: Regarding nhtsa action no. pe06010, i have a 2004 toyota sienna xle limited with awd with the tire pressure warning system (tpws) for my dunlop run flat tires (sp 4000). i have experienced punctures in two of my tires on separate occasions. both times the tpws only activated when the psi was about 5- to 15. the dealer indicated to me that the magnetic system will only activate once a tire's height becomes lower due to air loss, and the magnetic field is "tripped". the problem is that the run flat tires do not lose their height due to air loss until the tire is nearly depleted. so, the tpws essentially cannot properly function as intended, at least when run flat tires are installed. as to the dunlop run flats, they had to be replaced after only 19,700 miles. i know numerous other consumers have had similar experiences. toyota acknowledged the problem and relpaced my tires with a new set of 4 run flats at no charge (other than installation). typical price is $250 per tire. credit to toyata, but not sure what will happen when the new set fails. *nm
