When do 'you' change tyres?

[boydeee]

Would you be willing to swap rears to the front to wear them down that wee bit more?
The reason I ask is because I had an EP3 type R and I replaced the fronts. I ended up with premium front tyres and budget rears (thanks to the previous owner) Cue the arse end of the car having a tendency to slide out and keep me on my toes/scare the bejesus out of me. So I swapped the good tyres onto the rear and ran the poorer tyres down on the front so it had predictable understeer until I bought new tyres.
Up to yourself entirely, that was my experience, but then I had a mixture of good and bad tyres fitted! On my GTI I've just popped new Conti 5's on the front and still have about 6mm on the rears

I always change my tyres at the 3mm mark regardless.  The stopping distance on anything lower is scary even in the dry.  A colleague of mine is in the traffic police and they change there tyres @ 3mm for that reason.

I know its seems high, but probably sensible, 

The rules in Germany changed again in 2010 - regulations now require all passenger cars and motorbikes including vehicles from foreign countries to be fitted with winter tyres or all season tyres on all axles when conditions are wintery. So not only do they need 3mm or more, they have to have a spare set of wheels with winter tyres!

I guess thats where the vast amounts of part worns on ebay come from.

I think we should also have to have winter tyres here and they should have a minimum limit of 3mm and summer tyres a limit of 2mm

Now sorry but I have got to ask, why Jackie Threehorn?

Jackie Treehorn?
I couldn't think of a better name when I signed up many moons ago and it was nice and random,  a Cohen brothers film called The Big Lebowski had a theme of a big Porn producer called Jackie Treehorn.

bit bizarre I guess, but awesome film..

Love it.

I wait until about 2 mm,  and as the tyres are the only bits that touch the road is only by tyres with a good reputation like the 4 Michelins I bought 3 or 4 months ago, 450 quid  for 4. Another reason for not buying Chinese tyres to me is their not Chinese, everything is made there so it keeps a bit of money on our side of the world too. Win win.

I work for Cornwall fire and rescue and have to drive on blue lights to incidents , our policy is change at 3 MM and always michelins for some reason

[Finglonga]

Not sure I understand, the wear markers are at 1.6mm, so you're on the legal limit.

The wear markers are 2mm, the UK legal limit is 1.6mm. Manufacturers do not just make tyres for the UK market they are a world wide market.
