Hey guys,

been lurking around here a lot lately. I’ve managed to scroll through 56 pages of tire and lift posts and I think I’ve figure out what I need to do... now I’ve got to see some pics of this Set up. 

so here’s the truck, purchased on Memorial Day. 

Looking to run a 285/65/20 ko2 on my stock wheel.. with a 2” level.  I’ll end up doing a 1” block on the rear. But for now the 2”level is long overdue.

 

any pics of this setup on this wheel? I’m curious as to if it would fit. I know a 275/60 will. A 275/65 I think would too... However I question the 285/65/20. 

Or do you think the extra width isn’t worth the extra money per tire, and stick with a 275/65

Man I don't know.  That tire is 34.5" and I really think you would get rub with that height with only the 2" level.  I run 33x12x20 AT2's on mine with that level and am all good.  I think that is a roll of the dice IMO.

Congratulations on the new truck Bill.  BFG KO2 tend to run small compared to other All Terrain tires.  A friend has this same size tire on a 2018 2500HD Denali Duramax 4x4.  When I get a chance I will try to get measurements of the tires when mounted.

Mounted the 285's have a height of 33 and 3/4 inches.  This is inflated at 70 pounds of air pressure.

So after some more precise searching it seems it is a little to big :/

so at this point I’m looking st the 275/60/20 in nitto ridge grapplers .

 

ive seen it will rub with a level.. but those are on the newer trucks. If I recall the 16+ trucks are different. 

 

Im looking for a truck with the same wheels with the 275/60/20 and a 2” level to figure it out. So far I have yet to see that size with the nitto RG on the same wheel. 

Help!

With the 275/60/20 Goodyear duratrac

These tires have 16/32, where as the Nitto have 14/32 depth.

 

Im running them on the stock All Terrain wheels which are same as your except the painted accents.

 

I have zero issues and zero rub.

LMK if you want pics.

This is only photo I can find that’s a clear side shot. This is with the above set-up and maintains about a 1/2” rake, but it appears level and stance is just right.

      OCI, not when but why?

      By Grumpy Bear · Posted

      10 Ford and Chevy engines proven to reach 300,000 miles   You may note a common 3K OCI on this list of gas motors. I skipped over the diesels. Dh'O.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By jake111 · Posted

      Thanks newdude!  By the time manual selection is needed, I'm probably too much of a control-freak to depend on the transmission sensing braking to activate automatic downshifting.  I would be anticipating the situation and already be manually downshifting.   This truck replaced a 2004.5 LLY diesel with the Allison 5-speed.  Putting it in T/H made noticeable differences (when the torque converter locked, upshift points, downshift behavior).  On this 2024 gasser with the 10L1000 I haven't been able to detect much, if any, difference.  Ok, I can never tell now when the torque converter locks up.  But I also don't notice differences in shifting.  For downhills, I've probably already manually downshifted by then anyway.  Since it's also more awkward (than the 2004.5) to engage/disengage I don't even bother.  Or maybe it doesn't really matter with just a 3k lb. camper in the bed?   Thanks also for the list of reasons the charging system might select various voltages.  However, what I am seeing doesn't fall into any of those categories.  It very definitely, and very consistently, rises after coasting/braking.  Maybe not immediately, but not very long after coasting/braking.  Very consistently drops voltage when no longer coasting/braking.  It might also be interacting with the camper battery charging (I might disconnect the camper and see if it changes the charging behavior).  I also need to recheck turning on headlights for when I want to force it to charge the camper.   Another JR, in June I converted the camper to LiFePO4.  Since it's not a good idea to try to charge lithiums directly using truck, I installed a Victron Orion XS DC-DC charger (which BTW is AMAZING!!).  Being cheap, I only had to buy that one item (besides the battery, of course) to do the conversion.  The camper OEM 120v battery charger (only 19 years old and works perfectly) and the truck feed the input to the DC-DC charger (not at the same time).  But I didn't want the camper charger feeding back to the truck so I kept the old separator.  I considered replacing the separator with a 30amp diode but that means more work and might add another 1/2 volt drop.  One thing that surprised me was the voltage drop over the long 10awg wire run, so I can only charge smoothly at 8 amps (because the DC-DC charger is completely configurable).  Another reason I don't want an added voltage drop with the diode.  I might also be a little lazy but all this work is being done under the sink with a small cabinet opening.

      cam upgrade in CA

      By davester · Posted

      apparently CA smog is (or at least was)  checking that the vehicle is using the oem and/or a ca smog approved tune, so I expect you'll fail inspection doing it.

      Possible lifter tick after DOD delete

      yes, leaking exhaust will mess up o2 sensor readings, which in turn messes up fuel trims.

      286,740 Mile Services   8/6/2026   New AC Compressor. Refrigerant oil and dye, evacuate and charge system.  New exhaust system from cat back.  New Iridium plugs plus replace #3 coil Repair/rewire headlamp wiring (passenger side) and replace all forward bulbs. Polish lenses of both assemblies.  Pull rear rotors, clean and adjust parking assembly. Inspect, clean and grease front calipers. Check pads and shoes.  4 wheel power bleed of brake system. Dot 4 Reset idle speed 50 rpm higher New Serpentine belt.    Will need new pads in the rear in about 5K more miles.    Tax Title and License out the door just short of a grand.    AC clutch had bitten the dust. 1 year warranty on the pick and save replacement. Thing will make a Polar Bear cry Uncle.  He spent quite some time on the wiring. It was in the harness and he does nothing half. I got off cheap. I have considerable more light down the road. Sylvania Silver Star replacements.  Gas seal between the porcelain and shell of plug #3 was blown, cooked the coil. That was the cold miss.  Love the new exhaust. I can sneak into the neighborhood again.  Nice to have a working parking brake again. Belle Tire never got it done. That was disappointing.    This was one of her bigger bills and still way cheaper than a payment even given the oil consumption. This thing cost me under a hundred a month in repairs and normal routine costs. What is my incentive to replace it? 🤔
