A picture is worth a thousand words...most aren't nice. Here's the situation...Excedra Max with almost no perceptible wear. Picked up what looks like a 18ga brad nail. Yep, it went all the way through. It's in the bottom of a tread groove halfway between center and the outer edge. Hole is straight in (nail bent over). I've had good luck with patches and plugs in car, truck and lawnmower tires, but never had to repair a MC tire. Thanks Y'all.
