I believe that the widths of the factory rims for my 2007 Tahoe is 8.5" but what is the offset?
I am looking at some aftermarket rims and need to figure out what will fit? Is the bolt pattern: 6-139.7? Or what is the correct pattern?

Thanks!

 

I just installed some aftermarket 20's on mine....here's the specs:

20 x 8.5

Offset: 31mm Bolt

Pattern: 6-139

On Edit: I ordered these fromTire Rack ( Chevrolet Forum Vendor) very fast shipping and great products.
