Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

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.
