The run-flat tire on our Toyota Sienna AWD went flat, requiring a replacement. Unfortunately, out of all the tire stores, only the Toyota dealer had a replacement tire in stock. Every other place required a minimum of 5 days to get the tire. We were out of town at the time. What was interesting, was that when they replaced the tire, they said there was a gash in the sidewall -- it wasn't anything that was driven over. What I found more interesting was when I talked to my brother in al who has the same type of vehicle, he said that they had to replace a tire earlier in the year, because of a rip in the sidewall.

We had a tire blow out through the sidewall recently. We drive a 2004 Toyota Sienna le fwd with dunlop sp sport 4000 A/S tires installed as oem. We had just barely passed 26,000 miles when we had a side wall blowout on the driver side rear tire while travelling app. 70 mph on the highway in South Carolina. I pay attention to tire pressure and teadwear, so the tire that blew should have been inflated properly, and in this case I had already begun thinking about getting new tires because the tread was approaching the wear bars. This is a very poor-performance tire, and I'm amazed Toyota made a corporate decision to put these tires on their Sienna "family vans." Dunlop should be embarassed to even attempt to sell them.
