Even worse with a "sloped" brake track on the rim's sides, if the wheel has any hop to it at all, this affects the effective width of the rim between the pads, causing pulsation of the brakes.


"Maybe some of that tubeless sealant goo or something along the tyre bead might do the trick..."

That sounds like fun. Glued-on clinchers!
Seriously, as some formulations are liquid latex, and prolly give a quite decent grip!

Man, you shoulda heard that front tire blow. I was riding after dark, and soon many porch lights went on! Quite lucky for me, as I was able to make the repair on one of those lit porches.
