I'm not sure if the Tahoe's are the same bolt pattern as the regular 1/2 ton trucks, which are 5" X 5". Not hard to find out, though. Measure from the center of one bolt, or bolt hole on the wheel, skip one bolt, measure the distance to the next after that.
If they are 5x5, the only factory wheels that will fit, are from GM trucks, of course, then Astro vans, Impala's, & Jeeps. GM trucks use a larger wheel stud, so the other wheels may have to have the holes enlarged. I know the Impala wheels need this done to them.
You will also have to check the size of the center hole. I bolted some older style truck rallies on one of my trucks, & it was a major PITA to get them off the rear because of that. Doesn't take much to get the holes bigger. A small pneumatic grinder, an 80 grit cone, & five minutes.
All these wheels, (with the exception of the Jeeps, because I don't have any experience with those, I don't know), are 15".
The only factory wheels that are available larger than 15" are the '91-'96 Impala SS wheels. They are 17". These will require the bolt holes to be enlarged from 1/2" to 5/8", & they will need 1/4" spacers in the front, but you can use the spacers on the rear as well, for a uniform look.
Good Luck finding those. They're out there, but, people that have them, usually want stupid amounts of $$$ for them.
