Thanks for the help! I was eyeballing the 295/55 Trail Grapplers....any chance they'd fit without trimming?

 

 

Yes, you can still crank the bars on a 2500HD...even the new ones. I think the 295/55/20's would fit with just a few cranks on each side. My dad is running 275/70/18's on his 2011 HD, with about 3-4 turns on each side....and has ZERO rubbing issues, even with the factory mud flaps. As Blackout07 said, a 305/55/20 might even work with some trimming.

 

 

 

 

Awesome! That is great to hear, because I want to make some tires fit without any modifications. Thanks for helping out a lift stupid guy! So with 3-4 turns on each side, what amount of lift does that add?

 

Also, the 295/55/20's are about 1.4 inches wider than the 275/70/18's on your dad's truck....wont that extra width be an issue?

 

 

Just measure each side and crank until you get about 2". The added width of the 295s will be an issue. I ran 305/55/20s on an aftermarket 20x9, on my old HD with a 2" crank. I had to trim and hammer and they would still rub. That was on a GMT -800 though. Get your truck leveled out and get a test fit done with the 295/55s.

Even though the 295's are wider than my dad's 275's, the 275's are taller than the 295's....so it will probably cancel out. I've always heard that 1 crank of the t-bars equals about .25"...but I've never tested that theory.

Will most tire retailers order in a tire and test fit it for you or no?

In that size, they should. It's popular enough that they can sell them either way. I can tell you now, that those mud flaps will have to go. No way they won't rub on those.

I really wish Nitto had more 20" sizes in the Trail Grappler...something comparable to the 285/65/18 (32.83x11.93)

A little late in my reply but... I'm running 275/70/18 DuraTracs on a 2011 GMC 2500 Z71 w/factory mud flaps at stock height. Only a slight rub on the bottom air dam a full lock in reverse at odd angles.

      not all plugs will be used.  gm uses more generic harnesses that support most/all options, and if your truck doesn't have a specfiic option, the plug won't be used (commonly will have a dummy insert in the plug , or it'll be taped up, but some may just be left as is).  But it's sldo possible some p.o. has installed the wrong/cheaper parts that aren't correct for your vehicle...

      First off, I'm not trying to just get easy advice/fixes for the issues I've noticed so far.  I'll be combing through the site via searches and such, and if past experiences are any indication, should find what I need.  For the sake of conversation, though, I figured I'd post the handful of things I've noticed in the 12 hours since buying my 2010 SLE CCSB.     Indicator lights: Airbag and TPMS.  The tire pressures aren't reading for any of the wheels, so I'm pretty certain the sensors were either removed, are damaged, or are otherwise inoperable.  I used to mount and balance tires 25 years ago but am pretty much ignorant when it comes to TPMS.  My 2006 didn't have the sensors and this might be the fourth vehicle I've owned that does.     Radio: Rear speakers aren't working.  I removed the driver's side rear door panel and checked the speaker and wiring.  I also removed the sill and b-pillar covers to check the wiring.  A few minutes of Google Fu showed that this is potentially a head unit issue.    Switches: Power mirrors don't turn left/right.  I ordered replacement driver's door switches that should arrive tomorrow.  The windows and locks work but it was only about $20 for all of them.  The driver's side rear window switch lets the window down but won't put it back up.  I think the passenger rear doesn't work at all.  In the coming days/weeks, I'll break out my multimeter to check all of that.   Unknown wiring harness: There's a box attached to the front driver's side of the engine compartment, right where the second battery shelf is located.  There are three plugs, one of which looks like it fits a standard headlight-style bulb (9007 or similar).  It doesn't look like it's plugged into anything.  I'll do some digging and if I don't see anything elsewhere on the site, post some pictures here.   Unknown plugs on brake booster: There are at least two female plugs on the brake booster that aren't being used.  I think it might be a replacement/aftermarket, so maybe those are used for a different application, as there don't seem to be any unplugged harnesses and no indicator lights are on.   Little squeaks when turning: Sounds almost like a bushing around the bed of the truck.  I'll have to pay close attention as I get more familiar with the truck.   Clunk on acceleration: possibly the infamous drivetrain clunk.  My 2006 had it and I'm just not familiar enough with this truck yet to fully grasp what it is.   Anyway, my apologies for the vague and all over the place post.  This truck is new to me, and it's been four years since I drove my 2006.  With 200k miles, I know I'll need to learn this truck quickly to avoid having any major issues, despite being confident it's got much more life to it.  My 2006 had nearly 320k on it when I parked it (nearly 300k of which I put on the truck), and it was still drivable then, though I suspected the head gasket might have blown.  I'd hoped to have that truck back by now, but it's gone forever, as I detailed in my reintroduction thread.

      I always drive in Sport mode. With more driving, I am finding the initial response when accelerating is much quicker now🖕 Lou

      Is it an optical illusion in the pic or is the truck really squatting that much horribly?
