Heavy wear forming a lip on the side of a kerb on Balliol Lane in the Woodlands area of Glasgow. Such wear patterns are often put down to metal-rimmed cartwheels riding up onto the kerb while trying to manoeuvre down such narrow lanes. However, it's unclear whether such cartwheels would have been capable of wearing away solid stone.

I don't see why not if wet/grit laden.

Canal boat towropes used to grind impressive grooves (word derived from ground/grind maybe??)

@thisismyglasgow why unclear? Simple footwear can wear cathedral steps; cartwheels would be harder and heavier. And the wheel would be sliding over the stone, so any grains of stone detached would form grit to attack the rest.
@kw217 Personally, I think this is the case, but last time I posted something like that I got quite a few people saying it wasn't possible, so I hedged by bets this time round! 😀👍
@thisismyglasgow @kw217 I have seen instances of grooves on the running surface of causey stanes in Edinburgh and I believe these were caused by grinders used to level the surface after it had been laid
