I check pressures every time I ride, due to surprises I’ve had in the past. I’ve NEVER gotten over 6000 miles on a set of tires. Pirelli GT’s last 4000 miles, on average (low of 3600/high of 4400). R5’s last longer then the GT’s, have great feel, but I’ve chewed up the fronts pretty badly, which I’ve never done with the GT’s. I’m also on my 3rd, maybe 4th set of Rizoma pegs, so maybe I ride slightly harder.
