It does not have one - the Siennas have run-flat tires.
how do I remove the spare tire from a2007 toyota sienna
The spare tire release bolt is located in the rear cargo area of the 1998 Toyota Sienna. Look for a small "U" shaped piece of loose carpet on the floor of the cargo area. The bolt should be turned counterclockwise to release the spare tire.
Not on the underside. A full size spare would be too close to the ground to be practical.
In Sienna 2006, spare tire is below the 2nd right seat.
There is a big bolt right in the middle of the passenger side middle row. There is a flap on the carpet floor. open it and you will be able to see it. This is also where you will find the release in the 2005 Toyota Sienna.
check it in the internet and i have no idea
under the car in the rear
There is no space for a spare tire if you have AWD. That is why factory provides the Run Flat Tires.
It is located underneath the vehicle in front of the right rear tire.
what is the part for lowering the spare tire on 2004 nissan frontier
Yes, of course, it can fit in trunk.
If you have the Limited (aka XLE Limited) trim level then it was factory equipped with run-flat tires and there is no spare tire.
