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!
