Yes Runflats are notorious for wearing out rather fast. And are expensive to replace. Usually special order.
BTW, E85 [I]increases[/i] fuel consumption. This is well documented.
Yu were better off getting a FWD Sienna. Yu just picked the wrong model Toyota. There are many other better Toyotas for MPG. The 4WD Sienna was the worst pick. I know several people who own them. And, they got rid of the Run Flat tires!

Our 06 Limited AWD averages about 16mpg per tank. Driving is a mixture of city and highway. This is normal to me. Nothing to complain about.
The Sienna did not come with a spare so the run flats serve a good purpose for us. When the pressure goes down the sensor comes on telling us to check it out. If we are out in the boon docks we have 50miles to get somewhere to take care of it instead of trying to wait for a tow.
Also, there was an uneven wear recall on our run flats. The dealer replaced them with a new set at 30k miles. I figure I'll have to replace them again at 60k which will be the first time I will have to buy tires for this thing.
I can live with that...
