Re: 2004 Sienna Wheel Specifications & Lugnut Torque
1. Before posting, I had contacted topspy, who is pretty much sure he posted a Toyota document. Thus, there are no doubts that we have a valid reference.
2. For 2004-2008 model years, difference of 5 mm in offset between 16" and 17" wheels is indirectly supported by Sienna tech specs. In the U.S. and in Canada, tread width (i.e. distance between, say, front wheels [centers]) is different for 16" and 17" tires as if Toyota wants to maintain the same gap between the wheel and non-moving parts compensating for the tire width difference by, presumably, setting different offset.
For 2009 model year, situation is not clear, Canadian brochure might have an error. We need to look at Owner's Manual.
