Understand that most summer wheeling up here is in the mud. Muddy hills, muddy rocks, miles of muskeg... you get the point.
My main problem with the SSRs was that the lugs would deflect, reducing their effectiveness in the mud. While that would make them more effective in certain environments, like rocks, they were less than impressive in this application. They cut/chunked easily, and were almost as noisy as TSL bias plys on the road once they were used off road a couple times.
In snow? Well, they were OK, but not really any more effective than off-road tires costing $100 less. More often than not I would just use my old BFG ATs, which didn't have the same tread voids but had more effective siping patterns for ice.
OK. You lost me now. I ran BFG AT's for 7 years on two trucks, and as far as I'm concerned, with four wheel disc brakes and four wheel ABS, they were no better on ice than by BFG MT's. Everywhere else,my BFG MT's were 100 times more effective than the ATs. I would never EVER run the ATs again. In mud the lugs filled up and they turned into slicks. Same as wet, muddy snow. Slicks. The MTs would shed the mud and snow and dig down and bite. The MTs were a LITTLE louder, but not enough to be that noticeable and didn't bother me.
My SSRs?? When doing my research, I read that they were on par for noise to the BFG MT. To that, I call BS. My truck sounds like turbo prop airplane taking off. I got stuck in my Ford not far off the highway (with 33" BFG AT's) and had my GF come out with my rover to get me. My son and I had made it to the highway and were walking in the ditch toward home. We heard my truck coming from a LONG way off. I cannot carry on a phone conversation while on the highway and the stereo has to be up pretty loud. Convos among people in the truck are...taxing.
Performance wise? They are fantastic on ice, snow and mud. I am getting the torque steering but got my TTs the same time, so can't really compare that. I wasn't getting that before the TTs/SSRs. They are at least as good on ice and in mud as my MTs. They are pretty good for rock climbing, although once again, I didn't crawl much rock with my BFG MTs so I can't compare as well. That said, I'm pretty happy with how well the truck with SSRs performs on rocks, and there are several other guys I wheel with that use different tires, including another lifted disco with open diffs, CDL and 32" KM2s.
