Need to borrow wheels/tires for emissions

[COJeepin]

Does anyone have a couple of smaller tires (less than 34") mounted on an 8 lug bolt pattern wheel to fit a GM 14 bolt that I could borrow for a morning early next week?

Box of beer of choice in it for you ;-)

I am located in Westminster, near 120th and Sheridan and will ideally find someone in Broomfield/Westminster/Thornton area if possible.
