  • I have a 8" suspension lift on 38x15.50x20's .... love it
  • @ericpcronic
    You guys were instrumental in providing info for me prior to my 2022 Power Wagon build. Been running 38x13.50s since day one!

    I have Carli Commuter with BFG KM3 37x13.50x18 21 2500 6.7 with either 0 or +20(not sure which offset I have) and there was minimal rub after some trimming but zip tie the plastic back no rub on road but still some offroad under max articulation. Wish it was 12.50 instead and would probably have no rub so when this set wears out will probably be 37x12.50x18 KM3, love the KM3s amazing off road tire.

    I'm running 37/12.5/17 Nitto Trail Grappler MTs on my Power Wagon with 0 offset Raceline beadlocks. Stock suspension. Had to do plastic trimming and grinding/cutting of the pinch welds. Still rubs a little on the radius arm or sway bar when fully locked and guaranteed rubbing when fully articulated.

    My 2019 2500 Cummins fits 37’s on 17 inch AEV Katlas with no rubbing using full Pintop setup. Absolutely love it.
  • If anyone thinking about doing this listen to these guys recommendations and you won’t have any problems. 17x9 with 18 offset and just a very little rub on the plastic flair when turned all the way. I can live with that and no cutting

    WIldpeak R/T01's 37x13.5r17 +25mm offset & Ty Vole trim kit, gained a bit over an inch of clearance and it looks stock.
  • @LenTexDIY
    37s are the ONLY way to go, in my opinion. I've got them on my 2020 2500 (in my profile pic) on +12 offset 17" wheels. Thanks for the video!

    I have a 21 2500 with 4.5"-2" ready lift on axe 22x12 with -44 on 37x13.5 . Question I have is, I get pinch weld rub on passenger side only. Any thoughts on why just the passenger rub. Ty also will going to 12.5 take that away. Looks like it tracks right.

    You 1.5 Leveling kit with the 2.0 Fox shocks and front track bar allow me to run 37x12.50x17 ridge grapplers on 17x8.5 Raceline Minster beadlocks with +18 offset with very minor trimming . This is on a 2022 Power Wagon. Ride quality is outstanding.
  • I have a 2010 Dodge ram deez, that I was going to put 35's on. But now I'm wondering if I can go to 37's. Only have a RC 2.5 in leveling kit on it, no other mods, or upgrades of any kind. Not sure of what tire I will run, but it will be made in the USA, an a MT of some brand, unless you can recommend a foreign mt tire, money being a big decideing factor. Kinda lost on this offset aspect, but sounds like 25 offset would be right. Wanted to stick to my factory wheels, but from everything I watched an read, this may not work, not against pushing the wheels out some. As I have 3 in fender flares that were given to me for my truck. It is 50 % on road an 50 % offroad. But I live in Fla, an we have swamps with muddy dirt tracks, hence the reason for MT's. As I 've almost got stuck on muddy jeep tracks in our area with street tires, an we flood alot during hurricane/rainy seasons, not looking to relive any of that. BTW, I'm a retiree an built many big rigs 40 yrs ago, an not looking to build big rigs anymore, more about dependability an getting to my hunting spots in the woods, Any help would be appreciated, thx Bill

    Random question... I have really considered buying a Carli 3.25" system from you guys for my 2022 Ram 2500 Limited 4x4... I have also been weighing the 35" vs 37" but one of my bigger limiting issues is my garage. I live in Colorado so I like being parked inside on colder days (keeps the truck warm). My garage clearance is just under 95". Would you guys mind telling me how tall one of these newer Ram diesel 2500s is (include the satellite antenna please) with 37" tires and a 3.25" Carli lift?
  • I have a 2023 Ram 3500 dually. You mentioned finding 8.5-9” deep wheels, what’s the main concern here. I know you’ve put 37x12.5” tires on the stock dually 16 rims which I believe are 6.5” deep. I love the stock look but don’t want to risk something that’s out of spec. Thabks
  • @JamesSmith-ep7et
    How different does the Thuren 2.75 lift kit sit compared to all these Carli 3.25 kits? I get that the numbers indicate a 1/2 inch difference but is it that in real life? I still have yet to see a Thuren equipped truck featured here? Would this Guide work for Thuren 2.75 kit as well? Thank you!
