Bought our 2011 Sienna new off the lot back in 2011 and we are now on our 2nd set of new tires (3rd in some cases that 2 needed replacing). A total of 6 new tires with a vehicle that has only 30,000 miles on it is ridiculous. I have called Toyota about this issue and now our van sits in our driveway like a dead weight. We had a tire blow out on us already a few months ago in which we had to replace it. They go bald very fast and are no good in bad weather. I have never owned a vehicle in which I had to replace tires this often. It almost caused us a wreck when the tire blew out and we cant keep up with the costs of replacing them since they are so expensive.
