The SSRs have extremely weak sidewalls as far as puncture resistance goes. I went through 5 of them of them in 6 months on trails like Rubicon, and the Hammers, where I typicaly go years without a sidewall puncture. It a shame too, because they were a good performing tire, they air down well without getting to mushy, and they have great traction on hard rock, slick rock, sand and loose loamy soil. I never ran them in the mud.
My favorite by far, are SX tires, sure they are like riding on a cube for the 1st mile on a cold morning, but they have excelent traction, and are almost bullet proof, they also except a tire boot repair, much more readily than the radials.
Boggers are awsome also, but they are a pretty brutal street ride.
Thornbirds, are the laughing stock of the Rock Crawling world, and they have a shamefull reputation in the Mod Bogg circles also.
TSL are a good compromise.
