First Time Poster But Long Time Reader - Need a little help
I just traded my stock 2001 Silverado LS for a 2004 Sierra SLT Ext. Cab that's got a 6" Fabtech lift and completely bald 325/70R17 Open Country AT's on non-stock 17" wheels that I hate. I looked at this as a chance to put on what I want, but I am completely new to the lifted world and need a little help...
I've chosen a wheel (Helo 835 18x9, 18mm offset, 5.71 backspace) but have been unable to determine the largest tire I can use without trimming. (This means I've also not selected a tire, yet.) Combing these forums (searches) has yielded no usable help, as those running similar setups are either NBS, a different lift height, or have trimmed. I'm contemplating the following:
While I am asking questions, I'm also looking for a wheel-to-wheel nerf bar (with step) that will fit the truck. The trick is it's got an 8' bed and I'm finding few options for that scenario. Any advice there would be welcome, too, as climbing into the truck as well as getting to a truck box is tough for me without this.

Welcome to the club. I believe the maximum wheel backspacing with the Fabtech lift is 4.5". Check out N-Fabs step bars.:cool:

I had checked out N-Fab step bars but they don't seem to have 6-step bars for 2004 trucks with long (8') beds. About all I can find is Tough Country...

Much thanks for the response -- it was the piece of information I was missing to fit the pieces of the puzzle together, properly. Everything's squared away, decision-wise, and the appropriate purchases have been made. Now I wait. *sigh*

You'll be fine running 35x18x12.5 tires! 6in lift and 35 tire is a great combo
2006 Duramax LBZ
4'' Diamond eye to 6'' tip
16'' ion alloy, 33'' fierce attitudes
Lots of work left to do!

A little bit of information in case others might find it useful:
- With 4.5" backspace being stock for my truck and 4 5/8" being the backspace supported for a 6" Fabtech lift I elected to stick with 4.5".
- I found that my chosen wheel was available in 4.5" BS as a 17x8 rim... a bit smaller than I'd wanted but acceptable.
- The 17x8 rim coupled with my desire for Nitto Trail grapplers AND insistence on a D-rated tire for ride quality brought me to 315/70R17. The 35x12.5R17 (next size up) is an E-rated tire and needs a minimum of 8.5" wide rims -- both of which are no-go's for me.
P.S. I ended up ordering IC's 4" polished stainless wheel-to-wheel nerf bars (NERF431CH). Next I need to research dual alternator and battery setups (possibly with a combiner), as I want the redundancy of dual alternators and the discharge capacity of dual, deep-cycle batteries. It's a precursor to some heavy electrical additions.
