AWD Tire Problem
 We've driven our Sienna XLE AWD van for 17,000 miles.  The van itself is a great design.  The all wheel drive works perfectly in the snow.  Toyota's decision to eliminate the spare tire and use run-flat tires was a major mistake.  At 16,000 miles I had to spend $500 to replace two tires.  The other two aren't far behind.  The run- flat tires make the van ride like a truck, are un-reliable, over-priced, impossible to find, and and short lived.
