I was thinking about that same size, but might just go ahead and bite the bullet with the 275/70/18 bfg at knowing that I will lose some power and mpg with the larger and heavier LT tires

I've been running 275/65R18's with no lift or level.  I think it's the perfect size tire.  I would stay FAR away from an E load tire.  My Ko2's were E load and wow.... loved them towing and off-road but for daily driving it beats the truck and you up.  I dumped them last weekend for P275/65R18 Nitto G2's.  No looking back. I have been looking for new tires and wheels for my K5 project and seems like tires are now all E load and heavy.  Going with the OEM KO2's from a JL Rubicon Jeep. MUCH lighter and C rated.  Again, stay away from E load unless you tow or haul a lot.

I'm running the same size, but I did a 1.5" level shortly after getting the truck, with no difference in ride quality over non-leveled.  After the stock Goodyears wore out, I replaced them w/ Cooper Discoverers in 276/65R18.  Only a couple of pounds heavier than stock, so very little hit to gas mileage, and still rides good.  WORLD of difference in traction on wet roads and light mud over the stock tires.

Problem is most all 285/65/18's are E-rated tires so much heavier and rougher riding than SL tires. Plus a 285 I think would be close to if not having a rub issue in many cases? I went 265/70/18 with a 1.25 Bilstein level (1.5 spacer before) and I noticed the inch. Wider tires although improve grip in some cases are worse in others mud, snow, ice and have more of an mpg penalty even before the added E-rated tire...

Tyler, do you have any pics of this setup?  I'm torn between using my stock Z71 wheels, which I like and own or buying some 17s, which will ultimately cost me a grand more.  

 

If I could get a P rated 275/70r18 that was in a tire I wanted I'd go that route. Otherwise it's

265/70/r18.  -32.6" and 10.7 wide

285/70r17 - 32.8 and 11.4 wide

Just ordered a set of 10 ply Cooper Discoverer AT3 LTs for my truck in 265/70r18. They will be installed on Thursday, I'll be sure to post some photos. The size was recommended by the tire shop. Apparently 265/65r18 is an odd ball size for a truck tire.

Did you get these installed?  I'm trying to make the same decision for my '14 1500 LTZ Z71. Pics would help!

They should, though, of course, you'll have to get them remounted.
If I recall, my 2017 originally came with 265-65R18s and the 70s aren't much different:
Scratch that, they're nearly a 33.
You might need a 2" level.

    • Can anyone explain why the oil pressure runs higher after the DFM is shut off?  just installed the Pulsar Lt.
    • Thanks!  I figured as such; GM and other manufacturers have used standard parts and harnesses across trim levels and such for decades.  I pulled the blank accessory cover off of my commuter van (a 2016 or so Chevy 15-passenger) years ago and found the plug for a USB outlet.  It wasn't connected to anything, though (I tried swapping in an outlet from another van).  I was a GM Tech years ago (late-90s) and was pretty familiar with my 2006.  I might be wrong, but I view newer vehicles (pretty much anything made in the past 20 years) as being a lot more plug and play.  Meaning, more unused wires and plugs unless you have the Mack Daddy of vehicles.    
    • 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.
