Yesterday I whipped off my front wheels to inspect the tyres properly as I know I need a pair fairly soon and to give the wheels a proper scrub while I was there. I kinda wish I didn’t now, as I spotted this

It could be there for a long time for all I know. I can’t recall having any pothole incidents recently and the tyre has no damage nor is it leaking any air. I guess it is bound to get worse though isn’t it…
