Help please: having problems with the little blob/dimple on sidewalls of tire next to the valve after fitting new tires. Results in multiple pinch flats next to valve. I’ve tried the trick of pushing the valve in and wiggling around before/during pumping up but no luck. The tires are 35mm gravel king SKs and rims are alexrims df23 (21.6mm outer width/15.7 inner). Have tried 2 different types of inner tube. Is it possible that the rims are just too narrow for the thickness of the bead, forcing the valve to pinch? I realise this is a stupid problem but I’m running out of ideas here...
