Glass vs. sealant
Too much of a divot for the sealant to seal at 90psi, but enough for it to seal at 40psi. Which is not enough air pressure if I don’t want the machine bottoming out on any sort of substantial bump in the road. So I need to pull the tire, put a patch on the inside, then stick everything back together with new sealant and see if a patch + sealant works better than just sealant.
