Where to buy used Trailblazer SS rims

I might find my way into an Envoy and I want to know about TBSS rims.
Where and how much do they usually go for?

The truck has really shitty OEM Michelin’s on it now and it’s like driving on
hot marshmallows. It’s feels pretty floaty. I would like to eliminate as much of that truck feel as
I reasonably can.

I was thinking that new anti-roll bars, lower profile tires (tbss = 20"), and some lowering springs could help.

I have seen them used with OK tires go for $600…
New replicas and new tires are going to be more than I want to spend…

your gonna have to hit up the forums or score them on CL for dirt cheap
