Lots of pix with clean, new, oiled up, knarly, off-road tires on waxed trucks. None with dirt on them in conditions they were made for? :dunno:

Those coopers you're running are more aggressive than the BFG's....but your truck always looks pretty clean to me! :jester:

Was able to get the pressure load data from BFG for KO2 in LT275/55/20

 

KO2 GOODYEAR LS2

PSI LOAD 35 2403 *.91=2187*2=4374

35 1750

40 1920

45 2085

50 2275

55 2400

60 2550

65 2680

 

Here's the data with some extrapolation based on load/air pressure and averaged rate of change between 5psi increments. What this means is if you have a GAWR of 3900F and 4300R you only need 41F/47R to preserve your load rating without having to assume anything or having too harsh a ride. The smoothing isn't perfect i'm working more info to provide a more linear progression.

 

 

35 1750 36 1786 37 1820 38 1854 39 1888 40 1920 41 1952 42 1982 43 2012 44 2042 45 2085 46 2124 47 2162 48 2200 49 2238 50 2275 51 2302 52 2327 53 2352 54 2377 55 2400 56 2431 57 2461 58 2491 59 2521 60 2550 61 2577 62 2604 63 2630 64 2655 65 2680

Curious where to find the 3900F/4300R ratings?

 

(highest I can find is 3950F + 3950R axle ratings, and 7600 max GVWR )

Has anyone tried a KO2 in 285/65R20 with a 2.5" level? Lots of guys are running the 275/65/20 in various brands and the 285's are only .4" taller and .5" wider. I'm surprised nobody has posted experience with this size yet.

so far everyone in this thread has put 275/60/20 KO2 on their trucks. which is roughly 33x11, has anyone put the 275/65/20, it is basically 1" taller at 34x11. just curious because It may be the perfect size with the 285/65 maybe too large.

 

post pics let me know.

Here's the pics of my truck (2015 All Terrain) I have the 285/65/20 with a 2.5" level in the front only. There is only a slight rub in the front when i lock the tires while turning. I have taken it on gravel, mud, and packed dirt and haven't had any issues with the tires being too large. I love them, been over three months so far, they have been awesome.

 

Here is where the tire rubs on the inside of the well. Not sure if it is because the All Terrain's come with that carpet crap. It would be easy enough to cut out, and the piece it is rubbing on actually is sagging forward a little bit and at an angle heading towards the tire. Not sure if you can see it that well in the picture.

Here is the front and rear tires, sorry if they are at a crappy angle.

 

Forgot to mention, these are on the stock 20x9 all terrain wheels that come on the SLT Plus package or whatever.

      Breaking News!    I'm going to tell you that I'm going to tell you.  Then I'm going to tell you what I'm going to tell you.  Then I'm going to tell you.  Then I'm going to tell you what I told  you.  Then I'm going to tell you what I'm about to tell you on the other side of the break.  Then we're going to break. Then I'm not going to tell you what I told you I was going to tell you.  But I'll tell you something else that is Breaking News just coming to the desk that everyone reported on yesterday.  Then I'll tease a human interest telling I'll get to on the other side of a larger break. Then I'll tell you one item in 20 seconds and go back to an even longer break. Longest break of the night.  Then I'll tell you a fluff piece that takes 10 seconds and sign off into a three minute break while you wait for the next 30 minutes of rinse and repeat on the local news.    In al you'll get about 12 minutes of something, 5 minutes of which is worth hearing in a 30 minute show and 18 minutes of advertising at a sound level twice as loud as the news.    Of course you can switch to cable news and hear 12 different people tell the same four stories in much the same format as the Network News for 20 hours of which the majority will be advertising.  And four hours of late night Specials about things you wonder why you stayed up to listen to. Half of which will be repeats.....   OR you can go for a drive

      Audio Dampening and quiet

      By Afennell19 · Posted

      Did you ever figure this out? My 2022 Trail Boss, and now my 2026 LT did this from time to time.  I believe it was more connected to Android Auto and my phone being the cause. Maybe try going for a drive, sans cell phone.... and see if it happens?

      2026 Sierra 1500 Denali - Sound upgrade?

      By Afennell19 · Posted

      I have a 2026 Silverado LT, the non bose as well.  Upgrading the door speakers is pretty straightforward. You could honestly go to walmart, or Auto Zone/ O Reilly and get a set of 6x9s for the front, and 6.5s for the rear. You do also have to get some adapters for each, but they are like $10 a pair on Amazon. Then some plug and play harnesses that are about $10 a pair on Amazon as well.  And I would also suggest a 10 pack of the Amazon Basics sound deadening. Slap that all around the speakers and on the open metal of the inside of the door. And your golden.   I am currently doing this with my Silverado. Although I am having a bit of trouble because I am snooby I guess and bought some Alpine S2 S69c's which are 2 way components and I am having to wire from the door up to the dash....  Having never installed speakers before, its taking me just a bit to get everything correct. But if you dont buy expensive component speakers, and just some $40-$50 door speakers. You will DRASTICALLY improve the sound over these stock paper cone junk speakers. I thought my Silverado had an issue with the radio/ sound for a while.  Come to find out.  The stock speakers are just THAT SH*TTY   I cannot wait to have some decent sound in the truck   What did you end up doing?

      Parking Brake - Automatic Engagement Questions

      By newdude · Posted

      Its all automatic based on yaw sensor data.  If enough incline is detected, it engages.   My recommendation though would be to disengage it before driving off and not let it auto disengage by touching the gas pedal.  The HD trucks use the same setup as prior years, the drum in hat park brake.  But now with an electric actuator.  If you drive off repeatedly over time, it can torque the park brake shoes and can also prematurely wear them out.           Electric console shift will set the park brake on flat ground too.  Pretty sure they've got it programmed to activate every time.
