Mechanic's Note: The #1 cause of e-scooter flats is "pinch-flats" caused by low tire pressure. Installation Tip: Before installing, check the inside of your tire casing for the sharp debris that caused the original puncture. Pro Tip: To make installation easier, inflate the tube slightly (just enough to give it shape) before tucking it into the tire—this prevents the tube from getting pinched between the rim and the tire bead!
