For the last 3 Saturdays some of my riding buddies and I have been meeting at a different restaurant for Saturday breakfast and fellowship. Yesterday there were 3 of us that met. One friend rides a UClassic. After breakfast & a trip to a close HD dealer to look around, we went our separate ways home. I had been home for about 30 minutes when my friend with the Ultra C called me. I could tell in his voice he was very shook up. He said on his way to another errand he was going down I-485 about 65 mph when he suddenly lost air pressure in the rear tire. The bike violently when left/right left ect. He kept his head, but said he was scoping out the best place to lay it down, because it felt like it was going down.... all along though he kept telling himself just a little longer... Finally he got it stopped on an off ramp. We are giving the credit to our Lord for protecting him during this scarey situation. We got his bike home via a trailer & found a pencil size hole puncture left of center in his rear tire... nothing was found in the tire. What I surmise happen was that he picked up screw/bolt, piece of steel or something while we were out, and when he got up to speed on the interstate, the centrifical force plus a warm tire slung out the culprate there by releasing very quickly the air pressure. Here's what we are going to do when we ride as a group from now on. We are going to try to pay closer attention to each others tires, at stops, & when we start off from lights ect for things that may be in the tires or tires that look lower in pressure than are suppose to. We do our own safety checks before we leave home, but things can happen at any time.
