The 710s are the OE tire on our 2012 Sienna XLE.
The outstanding characteristic of this tire and vehicle combination is steering response. The steering is so light and easy it is unlike any other vehicle I've driven. It makes this 2 ton+ vehicle seem like a much smaller, lighter vehicle. To call this van 'light on it's feet' is an understatement. We've taken it on one 2,000 mile trip and thought it was great on the highway. There is little noticeable wear after 17,000 miles. We've also driven in quite a bit of snow this winter and, while they're no Blizzaks, they get around just fine. I went through the tire selection matrix on Bridgestone's website and they are recommending the Dueler 422 as the top-of-the-line tire for this vehicle but I love the way this Firestone works so well on this minivan that I'd be worried about any loss of the great driving dynamics from the factory.
