The wear indicators on tyres - is that 5mm?

Is the legal minimum depth 5mm?

When one side of the tyre is more worn than the other, say below the 5mm, but the other side is OK - is there a guide percentage of the tyre that the 5mm has to cover for it to be legal?

Legal minimum is 1.6mm but tests have shown that 3mm is realistic minimum in rain.

The centre 75% of the tyre needs to be 1.6mm minimum.

The wear indicators on tyres are the 1.6mm iirc...

Perfect exactly what I needed to know, cheers dude..

I knew it was 1.6mm, not sure why I suddenly thought it was 5mm :/

Was pretty sure if any of the tyre went under 1.6mm it was declared illegal. Could be wrong and wouldn't want to confuse the advice.

This could be called the Milton Keynes Law

Because all the ruddy roundabouts nacker the inside edges of your tyres

wear indicators mean nothing. many companies put them as high as 3mm, some as low as 1.6

they are not a legal requirement, and a good tool to get people to buy new tyres. pirelli for example put them at 2.5mm goodyear at 3mm

if you don't have access to a tread depth gauge, a good test is to get a 10p, if the ring of dots fall below the tread, they are still legal.

Do new 10ps still have those marks?

To be honest, 3mm is a much safer point to be changing tyres so I think it's a good thing if that's where they put the wear indicators:

oh yeah, thats why they put them at 3mm - its a recommended change depth.

5mm is only jut over half worn though, prob good for 10,000 more miles.
