Any pics on the web showing tyre tread wear indicators for worn tyres?

Looking at my tyres, I presume the tyre tread markings are at 90
degrees to the main grooves. But I'd like to find some example pics to
compare.

Thanks
Bruce

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.

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.

Pay no attention to that man behind the curtain.

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!

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
