What Wheel Specs Do I Need to Fit 37's on a RAM? 

Is it possible to run mudflaps with 37x12.5s on the Methods CJC exclusive 315's or would they be rubbing too hard? Im also contemplating running this setup at factory height if possible while saving up for a Pintop kit

That’s exactly why we make these videos!

That’s what we like to hear!

That truck is on a 2.5" Carli Pintop level system! We have a walk around video of that truck here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-3f5NLhxYEjQ.html

@@CJCOffRoadAwesome! I noticed that there isn't a listing for the 3.0 dominator system for the 4th gen Does that product exist?

Wouldn’t recommend 37s for a 5.7. Friend of mine says he get bad gas milage on 35s. BUT he does daily his truck....

did you find out?

We’re pushing as much as we can.

37s will not fit without radius arm rub on the factory RAM wheels.

Second gens require some major trimming even with these wheel specs.

With the suggest backspace you can bottom the truck and turn lock to lock. We actually use these things off road!

What really matters is the actual load rating in pounds of your specific tire. If that meets your needs then you're good to go!

Very minimal. Just some plastic.

If you're looking to run 35" tires, 17" wheels will definitely be best! Running a 35" tire with a 20" wheel just doesn't provide enough sidewall for good ride quality.

Your truck has the suspension of the older 03-12 trucks, so give this video a watch to see what you need for 37s: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-rkljYKtGuEA.html

with the factory wheels you'll have considerable rub because they're so set in.

@@CJCOffRoad Damn and there's no way to get around that eh? Like with wheel spacers or something?

@@ddev7376 I got that set up ,37in cooper tiers with stock rim. I did how ever had to get a 2in spacers to clear the rubbing in the front and back of the tire. I do feel a slight tremble once I go over 55mph, but definitely looks killer. Let me know how it goes with you.

We typically like to use them for the look, although it’s the same trimming for hard off road use whether you’re leveled or stock since the bump stops are in the factory location.

@@CJCOffRoad Thanks! I’ll be placing my order with y’all soon.

Yep, you'll just have to trim accordingly. A 0-3" lift doesn't really impact fitment, as the wheels and tires end up in the same place when you bottom the truck's suspension.

In theory, but in practice you’d have to cut the studs to make it happen. It’s complicated explain, but has to do with the correct spacer width not accommodating a proper bolt on style setup.

@@CJCOffRoad I see 1.25" is the smallest spacer that can be run without modifying the studs. But to be around the 5.75" backspacing I would need less than that requiring the studs to be cut shorter.

@@aarondemello2683 exactly. The math depends on the wheels, but it typically just about right to require you to cut the studs. So it’s possible, but fully committed!

@@CJCOffRoad thank you for the videos and info.

The specs are a pretty hard rule unless you don’t mind a little more trimming. You can do a 5.5 with just a bit more cutting of the pinch weld and plastic liner

@@CJCOffRoad Great info, thank you for such a quick reply.

What if backspacing is 4.5? How much am I trimming with the carli 3.5?

Yeah, that's the ideal number for the least trimming possible.

@@CJCOffRoad Okay, thank you!

There is no way to fit a 37” tire under a Ram truck sadly.

Assuming your truck has the 3.73 rear end, you probably don’t need to. Our shop truck on 38s with the 3.73 gearing drives just fine!

@@CJCOffRoad thank you for the info. Just kept getting told other places that I would have to re gear do to the tires being bigger and my RPM would be off and to much stress on transmission. Last question sorry. Besides your basic leveling kit. What other kit could I go with to go higher and still kind of maintain my towing capacity

Have you seen the Carli pintop level system? That sits at a 2.5” lift in the front, with 2.5” diameter King shocks tuned specifically for the factory rear coils and carli front coils. It’s the best ride you can possibly get while still maintaining factory payload and towing!

No I havent. Send me a direct link to it. So I could check it out. Thank you once again for your help

Right here! Call if you have any questions: www.cjcoffroad.com/Carli-Suspension-2014-Ram-2500-Pintop-Leveling-Kit-p/cs-dpt25-lvl-1419-d.htm

No you will always have to trim the plastic fender liner and corner piece. How much all depends on the exact wheel and tire combo.

We can always custom powder coat wheels ordered through us!

@@CJCOffRoad Have you fitted 37's w/ the 17X9 Raceline Avenger wheels on a stock 2019 Power Wagon yet? Wondering if I'd still have to trim?

Who do you use for powder coating?

That’s for any 37s on a Ram. 👍

@@CJCOffRoad Hey thanks, this is the second time I've asked questions on your videos and gotten responses pretty quick both times. Much appreciated!

At least a 4.5"

To fit 37s on a Ram you need a 8.5-9” wide wheel with +18 to +25 offset!

@@CJCOffRoad I have a 2021 Power Wagon...The truck is a bit different than the 2018s.... I would like to run 37s also, but do not want the tires to stick out super far...I'd like to be as close as possible to "factory" so that I can still take advantage of the articulation and tucking the tires up into the fender wells as well as not slinging mud and debris on my truck all the time (at east as much as possible).. I was thinking 17x9 wheel with -12 and 4,53" backspace?? Whatcha think?

No those are a whole other ball game! Give us a call and we can help.

You’ll want to run a +18 to +25 offset wheel that’s 8.5” wide, but on second gens you have to do some pretty decent fender cutting or have a body shop cut and section the fenders.

@Evil Mofo mmm okay buddy if you say so 👍 but i do like my 390HP 401T and 1950 pay load 9,600 pound towing its more then enough for what ill ever need. Then again i guess its just not for YOU and YOU are not everyone buddy but thanks for the commit 😍 have a lovely day.

Any tire larger and more aggressive than factory will drop MPG, especially around town. On the highway these diesel trucks do just fine on 37's and don't see a big hit to economy.

If you’re handy with a hack saw and an angle grinder to get some body panels out of the way? Haha

lukenburg Id look at the fabfours open fender system

They will with a 35” tire but not with a 37. To fit 37s on a Ram you need a 8.5-9” wide wheel with +18 to +25 offset.

@@CJCOffRoad thanks for the info! great videos by the way!

No problem!

RIGID INDUSTRIES 46510 FOG LIGHT MOUNT KIT 10-18 RAM 2500 / 3500

Just head to our website that’s in the video description and look under light brackets!

@@CJCOffRoad thanks I found them

@@billthepilot1 thanks I appreciate it

You've got the wrong wheel specs then!

@@CJCOffRoad yea they came with the truck when I bought it. But there is like, eyeballing, 3 ish inch between bump when straight

@@CJCOffRoad when money becomes less of an issue I want to get one of those Carli systems yall talk about and a new set of wheels and tires. I'd keep the wheels but I want a 5 one for spare but black rhino discontinued the model

It all depends on the wheel! Give us a calling we can give you an accurate time depending on options.

No this information is for 2500 and 3500 Ram trucks only. 1500s sit a low lower.

With a +12 offset wheel you'll be good to go with some basic trimming!

@@CJCOffRoad, THANKS. They're getting mounted today.

To fit 37s on a Ram truck you need a leveled truck. We recommend a +18 to +27 offset wheel that is no wider than 9.5,” as well as some mild trimming of the plastic fender liner!

@@CJCOffRoad thank you for the reply! I have a 3" leveling kit and will be sure to order new wheels then also. I was hoping to keep my stock wheels on the 22 2500 because it's the night edition with nice black wheels

Sort of. Factory wheels are super tucked in, so you rub the radius arms and sway bar at full lock. You'll likely want 2" spacers to make it work.

You’ll be able to fit them but with moderate trimming of the metal pinch weld and plastic. You ideally need +18 to +25 offset with a 9” wide wheel like the video states. Especially if you plan to use the truck Offroad

37x13.5 with a 20x9 that has the backspace discussed in the video will work fine!

@@CJCOffRoad would a 18x10 or 20x10 work just as well with a 37x13.50 on the Carli 2.5" leveling kit and later add-on Carli trac-bar? I'm leaning towards an 18" wheel for better ride quality instead of a 20" wheel.

Dually specs are a while different deal! If you're running super singles up front, we'd recommend a -12 offset wheel that's 9" wide if you want to push things out a bit.

Sure, just send your credit card too!

They still rub with a 2.5 level on stock 20s.... Mine do

Jose Gutierrez yea I’m running 37x13.50 on stock 20’s and they run. But I had a 20x9 with 0 offset and same tire and they didn’t. 2.5 level.

Rub*

@@COLTSWAY dam dude i can imagine. Im om 37x12.50s and it rubs a lot on the platinum 20s. I wanted to try 2.5" firsf before i spent carli money amd didnt like the 2.5 vs 4.5 so i whent with a readylift 2.5 with foxes.

Jose Gutierrez hell I can still turn everywhere I have to. I can turn like 95 percent before it hits radius arm and if I gotta get somewhere tight, I let her eat.

Not if you adjust it using AlphaOBD or an AEV Pro Cal.
