Toyota Sienna versus Jeep Wrangler Rims?

The people that know for sure are those at the Junk Yard (aka auto salvage yard , or auto wreckers) They get the books directly from the manufacturer EVERY YEAR about what car is the same as another of a particular year or model.  Also if there were other makes of car that have the same wheel bolt pattern.

Usually you stick with the same brand and you can flip between years.(usually does not mean always)

Each car manufacturer is designing their car in secret.  So the chances a Jeep fits a Toyota is like "Probably NOT"  Just because the wheels are the same (16") that is the ONLY thing that is the same.  Tires may be swappable and that is it.

Many cars have a 5 bolt pattern. But FORD is FORD & GM is GM & Dodge "might fit some Fords" but mostly not.  You got to measure the size of the center hole and the spacing wheel lug to wheel lug  If they are not IDENTICAL then they are not the same rim.

Easier and cheaper to buy some pretty hubcaps or NEVER LOOK AT YOUR CAR., leaving them unwashed and filled with mud because you used the Jeep as a Jeep...offroading (not some pasty highway/street vehicle.

I think they will fit but at $75 for 4, they are going to be corroded if not bent. ( out of shape I meant but they might also be stolen)

The diameter of the center hub and bore in the wheel, especially if they are hub-centric wheels.

The offset could be a problem if it isn't really close, but why not just get some nicer hubcaps? Those Wrangler rims are probably cosmetically beat up or bent. Otherwise they wouldn't be for sale that cheap. New OEM replacements cost $350 each. 

It shouldn't be a problem with a matching bolt pattern as long as the lug nuts have the same seating style.

i would ask a mechanic about it
