Tyre threads are the flavour of the month it seems 
Today whilst having some tyres fitted I saw a stack of old customer tyres. I was quite surprised how low some of the treads were, maybe 10-20% were below the legal limit.
So when do you change your tyres? Please vote in the poll above.
Me? Roughly at 2-3mm ie. before the wear marker (2mm I believe)
Here's one such tyre I saw.
