  1. A 3rd recommendation for the Continental AT's. I've got 17,000 on mine and they have lots of tread left, are still quiet, and provide decent off-road capability. I have run KO's and Cooper's and the Continental's are much quieter, and seem to have the same grip in the dirt/rocks. Not so much in the mud though....
  2. Well, I have had Cooper and BF Goodrich, and like them both very much. I just purchased a set of Continental AT’s, and so far am extremely impressed. They don’t look very aggressive on a website, but in person they look better. Great traction in dry off road conditions, but I have not had the chance to try them in wet conditions. Very quiet on highway. Load range E, so plenty stout.
  3. 2 inch black plastic pipe cap from Homey’s or Lowe’s. Fits over the top perfectly and keeps dust, ice, water, and all other associated road crap out of the fill tube.
  4. Forgot to mention that I took off the Goodyear street treads and replaced them with LT 275-65-20 KO2A's. cost me 1 mpg...
  5. So, here is what I have found with real world experience... My 6.2 Denali 4x4 CCSB has 7500 miles on it and an avaerage mpg of 21.8. My Tundra that I traded for it averaged about 17. My work truck is a 2016 F150 with the 5.0 and I am averaging about 19.5 over 11,000 miles. I just drove a rental Dodge with the 5.7 for 4,800 miles and got right at 20 mpg. All trucks 4 wheel drive CCSBs. All mpg's are calculated---not what the display says. And my 6.2 easily smokes any of the others.
  6. I changed out the factory Goodyear street tires on my 4wd Denali at about 2,000 miles. I went to the slightly larger 275/60-20 size. I like to drive off road so I wanted a "LT" tire. The only one I could find in that size was the KO2. 14 pounds heavier per tire, but really not that big of a change in drivability. I've lost about 1 mpg...
  7. Sorry I'm a little late responding but I put 275/60-20 KO2's on my stock rims on the stock suspension of my 17 Denali. No rubbing. I didn't want to level it yet and screw up the magneride. I will give it a couple years, and then level it and put 18" wheels and bigger tires on it. I like the extra sidewall for my ventures off the beaten path.
  8. Congrats on the new truck. You're going to love that 6.2.
  9. My 2017 Denali 6.2, 8 speed had vibration issues. I took it to the dealer and they replaced one tire and road force balanced them all. This took away most of the vibration. I have since changed tires to KO2's and I have no vibrations at all anymore. My 2017 Denali 6.2, 8 speed had vibration issues.

  10. New owner here. I just purchased a 2017 Sierra Denali CCSB, 4x4, 6.2 about a month ago. I got what I think was a good deal, $61,000 sticker, and paid $48,500. Plus they gave me $19,000 for my 2011 Tundra that had 140,000 miles (in excellent shape). I have been monitoring this site for the past couple months, and really appreciate all the input and expertise the members provide. I had to take my truck back to the dealer for vibration issues, and I was afraid I got one of the vibrators I have read so much about. Luckily they Road force balanced the piece of crap Goodyears, and replaced one. No more vibrations after that. Today I purchased some LT275/60 20 BFG KO2's at Discount and it is amazing how much better the truck rides and handles. No level kit installed (yet) and they fit fine. I have made a few minor mods and plan more in the future. Thanks to all of you for the great ideas!
