Just finished fixing a wee puncture and had a look at my tyres and reminded myself that i havent changed them for 3 years, tread beginning to look pretty bleak.
Do people have any wee rules for changing them, like so many miles, when the tread is x mm deep etc, or is it more just - they look like they have had it/i fancy a change etc? I realise that some folk probably have different tyres to the suit the conditions etc, but budgetry constraints mean i just have the 1 set etc.
