Just collected my new to me ST from San Antonio and rode it back home to Quesnel BC Canada I checked the tires before we left and the bike had a almost new 023GT rear,after about 1000miles happened to notice a big bulge in the sidewall right down on the bead it looked like the bead wire had broken, any how had to get a new tire,only one in the right size was a conti motion, not my first choice but when needs must! had 42psi in the tirethe bike was loaded probably at or near the maximum weight and we were riding hard and fast touching pegs in corners I noticed the tire was scaloping on both sides as if it was being run at low pressure (its not!) now we are home with about 2500 miles on the Conti the center third still has about another 2000miles left but the outside edges by the sidewall are down to the wear bars is this a normal wear pattern for this bike? looking at the tire I would have said it should have had another 5psi in it any comments
