  1. Yeah that is something to be concerned of I would say. If you do most driving under 50-55 mph, try to drive in M5 instead of D. This will limit the transmission to only 5th gear and V4 will not turn on. Keep your eye on the oil level. I say this assuming you have the 6 speed. I am not sure what the 8 speed does (M7 ?). Either way, that is a way to potentially narrow down the issue. Sent from my SM-G950U using Tapatalk
  2. GM updated the quantity from 8.5 to 8 likely due to excess windage which reduces MPG. Your dealer is taking the safe route. And the oil is most likely being sucked through your intake through the PCV lines. Consumption in V4 mode is very possible too. I change mine every 5k. I just hit 30k on my '16 and was down just about 1 quart. I do drive mine in M5 around town to reduce the amount of time in V4. Once out of warranty I will tune it. Thats my take on it..

  3. '15 1500 Gear swap

    I should have noted too that I have a z71 with 3.42 gears... So definitely not as bad as the 3.08. Sent from my SM-G950U using Tapatalk

    I hear good things about diablo. You can input your tire size, upgrade to 93 fuel and do so many other things. You can even send it out to a company called diablew and he makes custom tunes. There are many other options thats just the first thay came to mind. Sent from my SM-G950U using Tapatalk

    You will be fine. You will read on here most people who go up to 33's have no issues. If anything a high quality tune will be fine. Keep in mind trucks that come with stock 285 45 R22 wheels/tires.. That is a 32.1" tall tire. Keep in mind jeeps come stock with really tiny tires and LOW gearing and there is usually a need to regear. Not required on these trucks. I would say anything 35" and taller you may want to consider it. I am going up tona 285 55 R22 (34.5") and everyone who runs that says its fine. Sent from my SM-G950U using Tapatalk

    Do you have confirmation from bridgestone on the discount? Wonder if i could get one as well. Sent from my SM-G950U using Tapatalk
  8. Sidewall cracking

    Wow 20% is sweet. I dont have any stores near me unfortunately. Here are pics of mine that I just took. Again.. only 3 yrs and 30k miles.. Sent from my SM-G950U using Tapatalk
  9. Sidewall cracking

    Mine are doing the same exact thing but not that bad. Mine are on my 2016 rally 2 edition with 30k on it. Thinking of going with 285 55 22 nitto (g2 or ridge grappler). I have a 2.25 level. I am only hesitant because I have 2 sets of nitto terra grapplers "g1" tires that are about 7 yrs old and the cracking on them is NUTS. Nice tires but wow.. Wondering if chemicals in tire shine have anything to do with it. Sent from my SM-G950U using Tapatalk
  10. oem 22s on 285/55

    Looks sweet. I assume you have some rubbing.. if so, where? Are you hitting upper control arm or sway bar? Or just the fender liner? Sent from my SM-G950U using Tapatalk
  11. 2014+ Leveling Kits

    Also remember that when adding a level, it "pushes" the front suspension down, which actually brings the wheels in closer to the center of the truck, which makes it more prone to rubbing UCA, swaybar, and liner. My passenger tire rubs the UCA so slightly with stock 285's. Added .5" hubcentric spacers with extended thread lugs and all gone. I know most people cringe at the sound of wheel spacers, so did I. Never tried them other than my quads. So I tried them, and so far so good with about 3k miles on them zero issues. I do plan to go to the gmc all terrain 20's with 275 65 20 duratracs. I day dream about it. Hoping the 275 width won't rub, even then I wont mind running the spacers. I just like to keep my stuff as close to stock as possible without permanent mods.
  12. Vibration 70-80 mph

    My truck does sit most of the week in my driveway, I guess tires would be more prone to flat spotting and the higher air pressure reduced that. I assume it was also tires for you?
  13. How many people have experienced the notorious "chevy shake" between 70 and 80 mph? I sure have. But I think I found my fix. Had the dealer road force my wheels and tires (oem rally 22s with 285 45 22 bridgestone duellers). Still didn't work. I did notice it was worse after they did it. Of course they road tested it and cannot go over 65 mph. I noticed they lowered the tire pressure to 32psi thinking the tires would absorb the shake. So I tried the opposite. Pumpef them to 41psi (max is 44). And... next to no shake at 80 mph. I thought my driveshaft was out of balance. Turns out the tires are junk. The dealer even said they have a hard time with those tires. Figured I would share my experience for others to try. Sent from my SM-G950U using Tapatalk
  14. Duratrac 275/65R20 Review

    Awesome thanks for the quick reply. Those are the wheels I am looking to get. Preferably in gloss black but cant find them other than PVD black chrome. Found a set of OEM's might consider powdercoating. Where I am from chrome doesn't hold up well. Sent from my SM-G950U using Tapatalk
  15. Duratrac 275/65R20 Review

    I know this is over a year ago. Any updates? What are the specs on the rims? I am considering the same tires. I have the readylift 2.25 level with control arms. Thanks.
