So I know there's tons of threads about tire sizes for different setups, but I have gone through countless threads without seeing one for my situation. I'm running a 6" rough country suspension lift. I currently have 35x12.5 nitto trail grapplers on the stock all terrain 20" rims. My question is, what's the biggest tire size I can run without trimming? As of now, my options in mind are keep the same size trail grapplers, go up to 37x12.5 trail grapplers, or possibly switch over to 37x12.5 mud grapplers. Any suggestions would help, and pictures would be greatly appreciated!

You ain't fitting 37's on it with a 6"lift.

Here's mine with a 9" McGaughys lift and a 1.5"body lift with 38x13.50 x20 Trail Grapplers for comparison.

Yeah I wasn't too confident 37's would fit, just figured I'd ask people with more information than me. What's the bare minimum to be able to fit 37's?

9"
8" if you get the sawzall out

Just to keep from making a whole new thread, you wouldn’t happen to know how big of a difference 325/60R20 is vs 35x12.5 on 20” rims? I’ve got the 35x12.5 nitro trail grapplers on right now, but I found a pretty solid deal on 325/60 nitto trail grapplers. I know there’s only about an inch maybe inch and a half more tire, but will this cause any rubbing issues?

Cant tell you about rubbing issues but here's the comparison.

BTW I told my wife
Watch a guy pull up in a f 350 with no lift , and buy them.
I was right.
He was running some bald ebay tires.

They do look awesome.

A whole new ballgame now with 38's and 1.5" more lift c1ef02f9c32d49859462eb1d8ae4af76.jpg

I had an 3500 2020 at my neighbor's this weekend. Running 37s that looked like they could be 35s.
All Star edition 3500 with every bell and whistle one could think of.
Impressive!

You did the Zone 1.5" body lift, right?
I did the same and it took me two weekends.
Got the body lift and front bumper lift done the first weekend - I was beat!
Two weekends later, I did the rear bumper lift - took me the whole weekend.
It was nothing like doing the 6" body lift on my 1978 Chevy pick-up back in the day!
But, then again, I was in my 20s then! :D

    • Have considered installing a DC to DC charger in your camper to replace your isolator?  
    • Common failure.  You need to replace the fuel door housing.   The painted cover transfers over to the new housing.  To remove the old one there is 4 spots where you poke the plastic to release it.  
    • No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.      
    • Hello from Australia Just sharing that there is now a way to delete the active shutters entirely with just a plug in module. Opens up tons of room to light bars etc.
    • I have an observation and a question... 1) I watch the voltage closely because I have had to dial in the cut-in/cut-out voltages of the battery separator to my camper.  The "smart" charging drives me nuts.  Anyway, I noticed that when coasting for a while, and especially if lightly using the brakes (though not necessary), the voltage goes up from mid/high-13 volts to mid/high-14 volts.  Then it drops back down after stopping or going again.  Consistently!   The only explanation I can come up with is REGENERATIVE BRAKING!  Well, maybe that's a little bit of an exaggeration, but it's certainly free extra battery charging.   2) Driving on mountain roads I will use L and vary the max gear.  Things straighten out and I end up in L10.  Sometimes I leave it there for a while.  Is there any difference between L10 and D?
