[The tale of a tire]
I had a puncture in my tyre. I refilled the sealing liquid, inflated it to 3 atmospheres and rode approx 9 km (including stairs and small jumps) to work. Checked the pressue and it seemed to be quite the same as before the ride. I parked the bike in my office and then after 2 hours all of a sudden heard hissing - apparently the hole reopened. I turned the wheel so that the sealant might be just above the hole and the hole closed again. On my way to work I inflated it again to 3 atmospheres but then yet again the hole reopened - but then after a moment sealed itself again. I did not increase the pressue again and it seems to be maybe around 1.5 atmospheres.
What can I do to be able to ride 2.8 -3 atmospheres again (as I am rather on the heavier side...)? Should I pump the tyre to 4 atmospheres, let the hole open and close again and then I can ride with 3 a?
