You may need to put a reverse curve in the tire to open where it is hiding, but there has got to be something. Radial tire wires are very thin and difficult to see, as is glass, but the fibers should catch on it.
so the hole is on the inside , rim side , maybe slightly to the side , maybe its in the side wall , the only thing i have touched in since MARCH is adjust the brake pad up a bit it was sitting low , every time i get this hole its in a different spot , i have never seen a whole just appear like this ,
in this session i tried to do , it only happening on the downhills , they are steep hills and there is a bit of heat on the rim , but i dont think it could cause a hole like this :I
