Had my daily commuter, (Burg 650) parked out on the grass under a tree today cause I was doing concrete work outside my workshop. Neighbor came over and brought a cold beer to drink so we were setting under the same tree in the shade when I looked over at my worn front tire, put my finger on the tread to point out how I needed a new tire when I spotted a bubble the size of a small egg! I drive 70 miles round trip at 75 mph to work and to have that tire blow out on the drive could have been a disaster to say the least. Lucky for me I took time out to drink a beer and was sitting right next to the bike. Tire was a Michelin Gold Standard with 8,200 miles on it. Bike will sit till I get another tire on it.
