Reviving an old thread here, but I too am trying to find out the answer to the OP's question.

I have a 2021 Limited w/Air ride on order and at this point going with the RC 5" lift - unless another 6" becomes available in the meantime. I then want to add 20x10-18 wheels with either 325/60r20 ridge grapplers or bump up to the 37x12.5. I tend to agree with those that say the 35's are just a touch small for these setups.

Can anyone else chime in with solid feedback on fitment?? Photos too if possible...

TIA.

I am running a 35x11.5 essentially on a leveled limited. You should have no issues running 37s if you dont go crazy offset. -12 should be ok. and give you 2" of poke or so. Hopefully you have 3.92s.

You guys think 37s are possible with -44 offset?

I’m not entirely sure, from my research it seems -18/-19 is about as far as you can go unless you have a higher lift such as 8”.

Happy to be corrected!

Yeah im on the fence with this as I’ve already order the 26 inch rims I like 35s but think 36s would be amazing

I’m going to run 325/60r20 Ridge grapplers with a 20x10 -18 wheel - if I can source that size rubber here in Australia without exorbitant shipping ($500 freight per corner!)

My tyre shop here is on the case for me, I can get the BFG KO2 in 325 but haven’t heard great things about their performance in wet conditions.

If I cant get the 325 grapplers - I am going to give the 37s a go and see what its like!

All of the setups on custom offsets with the above specs look really good IMO.

Just wish there were more guys on here running the 325s with the 5” lift for Air ride trucks to compare

I didn’t see the request for pics until a year later. 🤣 I need some better pics. 3BF9CCEE-F106-41BE-8F2D-557DD26F6323.jpeg D0D244E3-7CB0-46B1-A19E-00BB09288536.jpeg

You have one of the best looking 1500s Ive seen. The 325s are perfect imo.

I spoke with my tire guy last week and he’s hoping he can source the 325 ridge grapplers for me - which are not common in that size here in Oz.

Thanks for finally uploading the pics, much appreciated.

Hey, this reply might be a little late to the party, but I have this exact set up. Started with 35s and they just looked too damn small. I went with the toyo atII in a 37x12.5 and it fit perfectly with minor trimming, nothing a sharp pair of scissors can’t handle. Not much of a difference in performance jumping from the 35 to the 37 with the 3.92s.
What is your offset on your 22x10 wheels?

Do you know the height from the ground to the middle of the arch of your fenders? I’m curious how much taller your truck is than mine because I want to fit 37s also. :)

Do you have to stay in off-road +2 the whole time?

Any spacers?

37s will fit only if it’s stock wheel or stock specs of your OEM 22s, with that you will need a 1/4 inch spacer.
22x10 -18 offset.. rough country 5 inch lift.. would 37x12.50r22 nitto Ridge Grapplers fit?

Are those factory wheels? I have a 21 ram limited and want to put a RC 5” lift but they say I can’t use the 20”factory wheels. I was thinking about using spacers to push the wheels out in the front.

Would love to see pics of the actual truck.
Cheers,
I have a 21 ram limited w/air ride and I want to put the RC 5” lift on it but they said I couldn’t use my factory 20” wheels said the arm would hit. Do you think by looking at the lift installed on your truck I could use spacers to push the wheel out ?

I just had the 5” RC installed on my 2020 w/ air ride and I’m running 325/60r20’s (35.5x13) on a 10” wheel. To me it’s the perfect look. 35’s looked a touch small and I didn’t want to run 37’s. I’ve had to do more trimming than the sticky posted here. I just finished my third round of shaping and trimming and hopefully got it. I tested at the parking garage at my office yesterday. I have about 3/4” before I hit. I did test it in entry exit mode and it rubs pretty bad.
I am running a 35x11.5 essentially on a leveled limited. You should have no issues running 37s if you dont go crazy offset. -12 should be ok. and give you 2" of poke or so. Hopefully you have 3.92s.
You’re just leveled, no lift above stock ride? Can I fit 37’s on my ‘20 Rebel with the Revel links and day star spacers?

I just did a 5" RC lift with custom link bars for an extra 1" . I put 22"TIS wheels and 35s but im not happy with the tire size. Everybody says stay away from 37s. LOL. I dont want to be like everyone else.......... How much trimming did you have to do? How does it ride?
