I am looking forward to maybe buy a set of 37x13,5x17, but can't find any info on the load range. How much plies do they have?

I saw that you have not gotten a definitive answer yet, so here is what I have for you off my 40"x13.5"x17"s. I'm guessing they may be identical???
Tread= 7
Sidewall= 3
GCM2, nice job on posting the photo of the sidewall.
According to Nitto's web site the 37x13.50R17 Mud Grappler comes in an E 10 ply rating.

Let us know if we can be of assistance.
I hadn't run a 37x13.50R17 Nitto Mud Grappler before but, I think it's safe to assume that it shares the same carcass as a Toyo MT and can tell you that they were a load Range E. The 40x15.50R20 Mud Grapplers were a Load Range D and the new K-Spec 40x13.50R17 Trail Grapplers I have now are only a Load Range C.
How's the ride difference between the C on Moby vs E on Rubicat? Any noticeable difference?
Actually, Rubicat is running 37x12.50R17 Trail Grapplers and they are a Load Range D. There is no noticeable difference in ride quality between them - both are very soft and comfortable. My old Load Range E Toyos were firm and noticeably rougher unless you ran them at 24 PSI.
The 37" Toyo MTs (load range E) I had also definitely like to be run in the 23-25psi range. Any more than that got a bit bouncy. Keep the pressure low enough though and I thought they were pretty comfortable.
