Tire tread bread, barbari, Afghan bread, sangak, Persian flat bread. Different names for the flat bread of Iran and Afghanistan that looks like it has tire tracks on it. A soft dough that is stretched out and fast baked. Similar to naan. Similar to pita. But richer in flavor than pita which can be very dry.
A classic style is to bake the bread on top of heated stones, though, in most commercial bakeries, it is done as shown in these videos.

The wonderful Alvand Bakery is on Eldridge between Briarforest and Westheimer. At one time, it was called Afghanistan Bakery. It closed for a while. Now re-opened. And I swear, when the bread comes hot out of the oven and is used to scoop up the homemade yogurt that I consider to be the best in Houston, and adding a little honey...what a fantastic breakfast!
