The EL casing is so much more supple than most tires that my realization of too low of a pressure in my Stampede Pass Els was a low speed washout on the switchbacks of multi user ramp on a repurposed bridge, decked with concrete, on a sunny dry day, just as Clayton's. No "mold release" or bloom of tread compound liquor involved, all my fault, but these tires are so fantastic that I'm not surprised that I have to relearn so much of what I used to overlook as a given about tires.
My tire episode felt like it slipped, as Clayton described, but as soon as it occurred I looked down and saw that my big turn of the bars (30-35°)‚ at almost no forward speed twisted up the sidewalls, slack to that sort of force against the contact patch, and produced the wrinkles that immediately caused the sidewall to washout. I was just fortunate to see what happened. Not too dissimilar to this appearance (that by horsepower, mine by a huge swing of the bars at low speed and an ill-advised low tire pressure): <https://lh3.googleusercontent.com/-HRz4IVf_N-8/V7xEbUawhMI/AAAAAAAAG4c/ezzpq__VpNc7Ir-Z_6EZuuOFztqufKUFwCLcB/s1600/Screen%2BShot%2B2016-08-23%2Bat%2B8.39.30%2BAM.png> <https://lh3.googleusercontent.com/-8LBaVNenv4k/V7xHOOGBwRI/AAAAAAAAG4o/b71YyP_0H_QGVrRB4bVEezAvHapf5VIQwCLcB/s1600/20160822_125243.jpg> Those Stampede Pass ELs on West Mountain, Hot Springs, National Park, AR Andy Cheatham Pittsburgh (Arkansas this week) On Friday, August 19, 2016 at 12:11:00 PM UTC-4, Clayton wrote: > > I have been using the ultra lights with the tan sidewall.
