hey man, I wouldnt trust that kind of patch, that goo may hold air, but hit a rut or log and the internal pressure hits 10 pounds or more and pooooof you're walking
Get a proper tire patch, or take it to a tire store, they will unmount it, patch it and remount, probably for 15.--20-bucks.
Or a tube. Either way you'll need a place to break the bead and do a remount. Tire patches work GREAT!
cheap too
