SR-A's are highway tires and pretty poor ones at that. They won't handle mud at all. They're bad in rain; they're bad in snow; they're bad at cornering; they're terrible on ice; they're not even very quiet or comfortable. They have no strengths, and Goodyear should not make them. Compacted dirt road? Hell, if it's dry, even slicks could probably handle that well enough to get you from point A to point B, but if any loose and/or wet material even thinks of showing its face, all bets are off.
Goodyear Wrangler SR-A was a stock tire for the 2012 JK?! For shame, Jeep! I get that lots of non-wheelers are buying Jeep Wranglers these days, but at least give them GOOD highway tires for their mall crawling.
