I bought the 2005 Limited Sienna Van brand new.
We have had to replace the tires every 23 to 26,000 miles.
We have had the tires rotated, alligned and balanced as suggested.
The tire manufactures cannot figure out why the tires will not last and have been replacing them free because they are not lasting until the warranty period is up.
Firestone has given us 3 free sets of tires, Gateway gave us 1 free and 1 prorated.
The local Toyota service manager told me that this is just the way the vans ride and it is normal?????
