The tread depth in the UK is 1.6 mm across 3/4 of it's width for the whole of the circumference. It changed from 1.0 mm some time ago. |

I laugh at 1.6 mm. What the heck is a fraction of a millimetre on a part that can wear unevenly as a tire can? Even if measured same offset from the circumferential centreline the depth can vary probably more than a millimetre much less a fraction of a millimetre. Regards, |

Zitat von Grumpy Goat im Beitrag #4 the limit was set by a crusty civil servant still working in inches and then converted by his (99.9% sure it was a man) younger assistant to mm. 1.6mm is eighth of an inch. It was also the distance from the edge of the 2 shilling coin (became 10p) to a concentric circle of dots stamped on the coin, which provided a handy depth gauge. There is a new, smaller 10p coin now which does have this useful feature. |

Zitat von Paul RS im Beitrag #3 ...is the correct answer (in the UK): Bikes: https://www.mot-testing.service.gov.uk/documents/manuals/m1s04000101.htm Cars: https://www.mot-testing.service.gov.uk/d...m4s04000107.htm Not that you'll catch me riding on 1 mm...! |

I can recall one time seeing both of my son-in-law's tires with the cords exposed. While I got all excited about the white stripes running around the tires, he didn't seem too concerned. But at least I got him to install new tires by having my daughter put the screws to him. Riding on bald tires seems to be quite common in the U.S., especially as most states here do not have any sort of motorcycle inspections for safety, equipment, emissions, sound, or anything else, for that matter.

Just change 'em every year. Works for me, saves measuring |

When I worked in the transportation business here in the states, the legal limit was 3/16” for commercial vehicles. However, best business practice recommended replacement of tires at 5/16” of tread depth. For bikes, Metzler recommends replacing at no less than 2mm of tread depth.
