Happened to me also ... but mine was a little older and the valve stem cracked. Luckily just the tread separated but the casing held up until I was stopped. That is when Emergency Road Service pays off. Two flats in one day makes for a long trip. No other damage also, just a few black marks down the side ... they cleaned off. Both tires were properly inflated at start of trip and 250 miles latter pow and then 20 mi. latter wump, wump, wump, pssssssss! Changed first one myself but I only carry one spare so called to have road service to bring 2 new tires and mount them. FUN, FUN, FUN, $$$$.
