Where is the extra tyre in 2004 sienna xle limited awd located?

if yit came with run flat tires it wont have a spare tire. if it has one, it will be under the van at the back.

Spare tire is under the van, passenger side, below sliding door. There is a release nut under the carpet about a foot in from sliding door and a foot or so away from the center arm rest/box. Use the tool in your tool kit to turn the release nut.

The 2004 Sienna Limited AWD does NOT have and was not offered with a spare tire option. It was designed as a "run flat" only tire car. I fought with Toyota over this for over a year and finally relinquished that they were unwilling to do anything for me. I run on conventional radials, purchased a spare 17" 5x114.3 wheel from the junk yard for 5 bucks and put and put the best of my old tires on it. Have not as yet needed to use it, but it's stored behind my the right front 3rd row held down with a bungee.

thanks bro
