Maxxis Sports won’t stay on the bead

An old MX racer trick is to drill some small holes and put a small machine screw INTO the bead to hold them. Prevents rotation on the rim, and would keep the beads from coming back out. Obviously not manufacturer recommended, but I’m convinced it could be done, and work. And if you were worried about air loss, a small bead of silicone around the outside seam would help too… I’d be tempted to seat the tire to around 40 psi and then put them in a hotbox (see LTO racing…) or non-cooking oven and let them sit a while, then see if they’ll stay… Alternatively, just drill and tap some holes for beadlocks. I don’t like the air loss potential with beadlocks, though…
