Tread wear indicators: what do they look like?

They're usually a different colour to the tyre? Red?

Mine are el cheapo budget tyres. Probably from China.

It seems I should be looking for a 1.6mm high rubber bar in the groove. When the tyre has worn down to this, the top of the rubber bar and the tyre service will be flush.

I've never seen ones which are different colours to the rest of the tyre before. The ones I've seen are just a small lump in the main grooves at the minimum depth, same colour as the rest of the tyre.

The message from "Dave Plowman (News)" contains these words:

What, treadwear indicators? Not that I've ever noticed.

They're just ridges at the bottom of the grooves - sometimes marked with TWI on the sidewall.

What are you on plowman? :-)

But you shouldn't be letting the tyres wear down that far anyway, for your own safety. Not less that 2mm really.

My current set of inherited-with-the-car tyres will still have stacks of tread when they are changed, simply because they are just shocking in the wet. Hopefully I can live with them through the summer, but only if it stays mostly dry!

I had a set of Avons like that - honest. ;-)

What ever you are on Dave, I want some too. :-) Making the tread wear indicators a different colour would be quite hard to do given the tread profile is extruded. Are you not getting mixed up with the circumferential colour bands applied to the treads to ease identification of tyre sizes ? Because they are applied to the tread before the tyre is put in the mould they can sometimes drop into the tread grooves and can appear by chance to drop in wherever the TWI are around the circumference.

Michelin put a little michelin man on the sidewall to show where they are...

Professor Prost had the same attitude LoL
