if it was reg cab, 20's but crew cab... def 22's.

what a coincidence... i am picking up 22" RTS wheels on Saturday with 305/40/22 Kumho Ecsta tires... I have an 06 Black CC, I'll post pics as soon as I can....

I'm trying to decide the same thing myself. I'm looking at all the pictures I can. Can't wait to see the black CC ^^^

The 22's will look great. good luck.got any pics of the truck

22's is the way to go.

22's... But if you wait till next year... The consensus will be 24's.

22's for crew cabs... 20's for everything else. Nice choice of wheel BTW. I'm considering 20" black RT-S wheels myself.

The 22's will look better, but keep in mind the HP you will lose. You'll be slow off the line. Its takes more to get the big *** things going. Now you will have throw a radix on it, to get it moving.

With 22's you can't lose. I've seen those wheels in 24" on a body-dropped crew cab and they looked damn sweet.

ive got 22's on my truck (ECSB) dont notice the HP loss too much, definately notice it when you try and slow it down tho
mine sits stock with 2" rear drop shackles looks nice and serves my purposes
I have 22" chrome and my buddy has 22" black wheels, side by side the black ones look much smaller
definately 22's on a crew cab
