I tend to agree with Mr_DIY
I've never seen an SSR preform very well offroad
Onroad they're decent, but offroad, they've got horrible traction. Personally I've run BFG ATs (on a fullsize dodge) BFG MTs, and MTRs. I think the MTRs and the MTs are a pretty comparable tire, and I've never had any problem with the sidewalls on either one
When I went through the 'con for the roundup, I didn't air down (didn't want to lose the ground clearance under the center frame of my IFS, and I was thoroughly pleased with the grip of the MTs, and the sidewall flex
I usually run them between 25-30 psi, and Have about 25K on them, with a little more than half tread left.
I think my next set of tires will be a set of TSLs, a little better offroad preformance, and I'm not driving my truck near as much as I used to, so the onroad manners won't be as big a deal anymore.
