When to change tyres?

boyesadabest:
I’d say you were lucky to get the bandvulcs down to 4mm. Every one we’ve run has always gone bang before its anywhere near worn out, although i’ve only had experience with bandvulc trailer tyres. Someone did tell me the bandvulc drive tyres were good

Bandvulc drive tyres and no this isnt a one off.
