Toyota rims on my C10?

[Snowbound]

Let me update my info:

I double checked my wheels and lo and behold, they shipped me the wrong offset! I have +19 offset on the truck right now and they are tight to the inner wheel tub. Zero offset will put me right where I need to be.

Now I need to sort this mess out.......

Do you have the factory wheels on the truck? I was not aware they made a 16" wheel. You may have wheels off a newer truck, which have way more offset, putting them in too deep.

Pop one off and measure to be sure.
