Vehicle: eco reco L5+ stand up electric scooter, max spd 20mph https://ecorecoscooter.com/product/l5/
Tire picked up a 3/4" long sheet metal screw. Now as the picture shows, there's a solid foam-filled ftire on this scooter with a hole in it.
Multiple tire shops in and around Portland Oregon can't fix it, and although I can run with the rear tire with that hole in it, filling in the hole will lengthen the tire's remaining life.
What could I use to fill in that hole so the tire lasts longer?
