So why won't ATX Predators fit on a Tacoma??

I've had a few posts recently where I mentioned ATX Predators being what I planned on putting on my '09 Taco...after emailing a guy who I was going to get them from on eBay, he told me the 16" Predators wouldn't fit a Tacoma because "the hub bore is not going to fit". He said only the 17" ones would work. Can anyone confirm this and explain exactly what that means? Also, I've never read anything about those wheels not fitting, how do I even know what wheels will work and which ones won't?

It's just really frustrating because I was dead set on them and there aren't really any others I like near as much..ugh.
