Many Valkyrie owners have had similar experiences. However when they don't blow up, they're a good, long lasting tire. I've ridden my 2 Valkyries 110,000 and 179,000 miles, and run Avons most of the time. Mileage was always great, with the fronts lasting over 20,000 miles. The only tire that ever failed was the OEM Dunlop. So many of those failed that they got the nickname 'Dunflops'.
