I sort of take the results from the Silca tool as a Minimum. I guess I should have said that. I have gotten a pinch flat and dented rim on the front, but I hit the edge of that pothole hard. Earlier that same day I rode a trail down by the river with some short rocky portions no problem. But the rocks down there are usually rounded by water.
Maybe you should give Josh some feedback if you are getting double pinch flats. -Dave J On 5/7/20, Andrew Letton <let...@flash.net> wrote: > I recently had a similar experience with the recommended pressures from the > Silca tool - for Snoqualmie Pass tires and rocky fire roads - double pinch > flat on a recent ride.cheers,Andrew > On Friday, May 8, 2020, 04:20:07 AM GMT+10, Corwin <ernf...@gmail.com> > wrote: > > I don't think I would trust the Silca tool.
