| Description of the problem | The vehicle has been wearing tires down unevenly to the point steel braid becomes exposed. It has had 3 sets of tires in less than 2 years. It has been aligned twice. The rear wheels are not within specs and are fixed and in adjustable. Toyota has refused to look into the problem any further and has stated that it might be how the van rides. Having the alignment off causes the tires to wear down to an unsafe level and it affects vehicle handling and performance. |
