Since posting “Toyota Sienna Run-flat Tires? Spare Us,” we have received a letter from Toyota, sent to 2004 through 2006 Toyota Sienna AWD owners that offers a short-term remedy to the reported tire-wear issue:
"Toyota now has supplemental tire warranty coverage offered for a period of 3 years or 36,000 miles from the date the vehicle was first used. Uneven or pre-mature tire wear is being covered and is limited to vehicles equipped with the Dunlop SP Sport 4000 DSST and Bridgestone B380 FRT, both runflat tire models in the P225/60R17 size.
What you should do if you have or had this condition: Contact your Toyota Dealer or Toyota's Customer Experience Center at 1-888-270-9371."
If you previously paid for replacement tires for this condition, Toyota may process your claim. Owners of effected vehicles should also be receiving a letter to describe the conditions of the warranty.
