Must have been an option, the 2009 le i have uses one piece wheels.

 

I think you're correct. Probably was an option. I bought my Sienna from a Toyota Dealership preowned in 2011 after my 2002 was totaled in an accident. I like the hubcap you found with the Toyota Emblem in the middle.

 

Here is one,
Oops, its 16" but it looks like your tires are too.
Clicky

 

You have 16" wheels,

 

For real?

 

I know...this is a beginner thread LOL

 

Your good, there in no bad question , i think smerk has nothing better to do.
Maybe his user name should smirk,

 

I had bad luck with cheap aftermarket wheel covers.
Have you checked the local salvage yard?
My local "junk yard" ordered used oem a lot cheaper than I could find elsewhere. Oem will last you forever.
3 of my mine are still the originals with 526k miles!

 

The rims are the size the tires say. 225 60 16... 16" rim. 225 60 17... 17" rim

 

I have 16" steel wheels on my '06. Back when the wife drove it, she lost a wheel cover. I picked up a used one from eBay for $65(ish). In teaching her to drive, my daughter curbed a wheel, needing a replacement and I got aftermarket. It looks and functions identically. The only downside is that the Toyota logos are missing from the aftermarket ones and I wasn't motivated enough to unglue and reglue the old one.
