what is the minimum legal thread depth on a motorbike?

Hi ya,
what is the minimum legal thread depth on a motorbike tyre in Ireland and then in the UK?

I've found 2 irish websites that contradict each other, the goverment sponsored http://www.citizensinformation.ie/categories/travel-and-recreation/motoring-1/driving-tests/motorcycle_driving_tests_in_ireland says 1mm and http://www.bikebuyersguide.ie/bike_safety.aspx says 1.6mm. The government site then references the 1991 law that states 1.6mm.


Thanks, Tom.

It's 1mm for bikes, 1.6mm for all other vehicles. The link to the law on the government site says that

& the legal thread depth for mopeds is "As long as its visible"

You'd be mad to drive with 1mm on the tyres.

1mm for mopeds as well

madrab

maybe they changed it but it used to be a visible thread covering the tyre with no bald spots for mopeds

You should have seen the Dunlop 220's I had on the old SV.
19500 km from new and including 1 trackday.

Squarer than a square with a flat spot.

Nowhere near that on the new one, BT020's and their dual compound are still squaring off even in this weather.

Most tyres have a wear indicator in the tread, dont they?
