About 3k miles on my TKC 70 Rocks, 75% pavement, 20% gravel/hard pack, 5% trail/off. Rear: Pavement; good grip dry and wet, no perceptible loss of traction on wet. Wearing surprisingly well for as much as I’ve had it on the road, the blocks still have sharp edges and plenty of bite. I ride the throttle hard and the rear has never stepped out on the road. Gravel/Hard Pack; good traction, even across the face on angles, never had any lack of confidence in the rear. The lugs are decently spaced so it did chuck an odd stone here and there, but nothing I would be concerned about. Trail/off/mud; excellent bite, clears well. This is the least of my experience thus far with this set, but I don’t see any concerns taking it on the trail or in the mud. Front: Pavement; holds a line decent. No loss of grip in wet. Tends to induce some wobble much lower than expected for me, as low as 85+ when fully loaded. Gravel/hard pack/trail; has a tendency to wander, not particularly confidence inspiring at holding the line. Washes out after a bit of fill. Bottom line, would not buy the front again. Would absolutely buy the rear again (although I did get it at 60% off, not sure I would pay full price but that’s probably more down to me being a cheap ass than a value judgement on the tire).
