No, I think he got the 6-bolt 22’s for his Envoy SS454.
Wait, what?
get the 15’s. stock dodge 15" wheels clear the brakes so thats a non issue.
a 15" DR with a semi squishy sidewall is going to grip far better than a 16 or 17" wheel with a rubberband so the car doesnt sit like a monster truck.
mark, you put the 175 shot on the car yet?
Brian
does your srt have stock brakes?
can you fit a 15 over stock brakes?
if you can then i say 15s all day
i just said that. 
i let a friend borrow my slicks and i have them on 15x6.5" shelby daytona wheels.
