Rode this Martello TNT for a year. It got rounded on the inside edge of the side knobs and lost a lot of hardpack grip. These knobs are stiff so they don't undercut like a lot of tires. Since there was so much good rubber left, and I had an extra half hour, I got the dremel and cut a notch on that inside edge. Grip is good as new. Can it go another year? Let's find out.
