Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

There are two little holes in the center section of the tread, just look around and you'll find them. When the tire wears down to the bottom of the holes it's used up.

Thanks, I will look for them....and if I dont see them I suppose it's time for new ones!

edit: I think I see them....2 small holes, about 2 mm in size is that right?

Yup, those are them. There doesn't seem to be any consistent placement of them on the tire but once you've found them they're easy to keep track of.

Look for the triangle with "TWI" on the sidwall side that has the "rotation" arrow.

As they get worn out the actual indicators get harder to find. The TWI is the way to spot them.

Bumping my own thread to say thanks for the help (love the triangle with TWI)....and a follow-up.

Once the dimples are obliterated, do we have a general sense of how much life is left in the tires??

all the tires I've used have a tread wear indicator. These threads start showing through the rubber. When you see them all the way around you need a new tire.
