Yep full knob, I have over 6k on mine and they still have 1500 to 2k miles left on them. I took them on a 4k mile trip to Banff Canada last month and they did great. I have gone up Palomar mt in San Diego with both the RA and the TkC80, and I prefer the TKC80. But that's just me it may be totally different for you all.Arent the TKC80's the knobby tires? They look awesome on the strom, but I'm not sure I would use them for myself. I am on pavement 99.9% of the time and I want a good street oriented tire. The TKC80's do look very cool on a strom however.
