Finally riding a big boys bike
Sounds like the Coker made tire, had the exact same thing happen in 98 or 99ish. Was working in Dad's upholstery shop when "the shot was fired." Lol It took us 15 minutes to figure out where the sound had come from. Looked over at the row of bikes and about the 3rd one in was sitting a little lower than usual. Sure enough, 2 days after the tire was installed, the cord ripped wide open, diagonal from top of the bead to the white to black seam. I've valued my original 50s and 60s rubber ever since. A friend of mine just had an older restoration job Phantom do the same thing not too long ago....we're pretty sure they were Coker tires too.Yup me too, been filling up my tires to where it feels right. All depending on the conditions of the road or how I feel on any given day. Sometimes cruising I might air them soft others, good and hard and that's both, road bikes with higher pressure and ballooners; never had any problems since I was a kid. That is, not until I had a like new set of Schwinn Typhoon cord from a 1998 ballooner. IDK but about 3-4 days later, sitting in my garage with all my other bikes, one just popped. It blew right through the cheap a. cord and ripped the tread rubber about 1-1/2 inch across, complete trash. I'd trust a Kenda before a modern Schwinn tire now. Hell, the cord on the Schwinn looks like waxed paper or cardboard too.
Disclaimer: Although my garage is completely drywalled, it can get awfully hot in there. That's the only reason I guess it could have popped. Albeit, never had one but that, blow on me, in the many years I've lived here. I been a little careful on Cheap a. modern Schwinn tires since.
