Definitely but the right 37s will always give you the ability to run less pressure unloaded than any 35. Trust me, I've looked for hours trying to prove differently. It's because the 37s will give you over 3800# load at 65 psi while the 35 require 80 psi to do the same.
I post the Toyo table constantly btw. It isn't really a "Toyo" table. It's actually from the TRA and is applicable to any brand of tire so you can use it for any manufacturer as long as you match up the size and numerical load rating. Super good thing to bookmark if you change tire sizes on every truck you buy.

With the same load rating, for sure, for the most part....
My point is that it isn't that simple. You MUST consult an inflation table to confirm
Simply saying a 37 will always give you a greater load rating at every psi than a 35 is not true.
It has more to do with just diameter.
Load index, diameter, and width all come into play.
Even with all those in play it still isn't 100% predictable
And since you say you've spent hours to prove differently, you might like this...
This is from Toyos inflation table you just linked to. Page 26
A 35" tire @ 65PSI has the same load rating as a 37" tire @ 65 PSI
Even being the same load rating, your claim that a 37" will always have a greater load rating than a 35" is false.

Carli did a good write up about tires and pressure awhile back, have you seen that? Mirrors pretty much what your saying.

Who runs Index 121 tires on a new Ram HD? Compare the ones that are closer to 4000# capacity and get back to me.
You do realize that right in that image is a 37 that has 3525# at 50PSI, right? Like I said, " The RIGHT 37s will always have more load capacity for the pressure than any 35."
If you are willing to go up to 18" wheels, the 37x12.50 has a 3970# rating at 65psi.
Come on man. You aren't going to win this one.

Go back and re-read the my original post, quoting you.
You are getting bent out of shape for no reason.
I'm not arguing with you, simply pointing out that your claim that simply going to a 37" tire will net you a higher load rating than 35" at PSI just isnt true 100% of time.
For the most part, yes it does play true. But 100% of the time, not the case. That is fact, as shown in the screen grab I posted.

What part of the RIGHT 37s don't you get? It's right there in black and white in YOUR image.
Maybe this is better. The RIGHT 37s will ALWAYS give you the ability to run less pressure unloaded than any 35.
True.
Trust me. I could care less about convincing you. It's the other guys searching for info in the future that should know that if you pick the right 37, you can run significantly lower pressure and have a much better ride. If you pick the wrong one, like the one you underlined, which would be a very poor choice for an HD truck...well then...you chose poorly. Those tires have significantly less capacity than the stock tires on any current HD truck and should never be part of a discussion about a '15 Ram 2500 as this thread is about.

Anyways... I order a thuren build it yourself kit.
2” front coils
Fox 2.0 front and rear
Thuren active rate sway bar
Thuren front track bar
Thuren steering dampener
Rear coils staying oem to keep hauling performance
And a thuren rear track bar
I have a buddy who is custom making front and rear bump stops for this truck. (DuroBumps).

Awesome! Just make sure you get the alignment right so you don’t chew through tires.
This seems like the exact package I'd have put togeather. Looking forward to hearing how you like it. When do you expect to receive the components? Self install?

I’m hoping it will give me what I need for the dirt but not take away from payload capacity. Thuren hasn’t given me an eta on parts yet but hoping this week. The install will be entirely done by myself. Never had a solid axel rig so I’m excited!

Kind of hoping I do chew through these tires... hate the ko2’s. I’ve done a bit of research and I think I’m going to go with toyo mt2’s for the hard tread. Thuren gives a good alignment recommendation on the page correct?

I agree with you on the BFG’s, they are not the tire for a heavy diesel truck. I’m now running the Toyo MT, I am extremely impressed with them, also they are surprisingly quiet for what they are. Yes thuren has alignment specs, if you have issues met me know, I’ve been through the alignment a few times.
