I would be willing to bet it's cold weather. Summer tires become like hockey pucks when it gets colder out. Mine start doing the same thing as the weather gets colder (Now I have my snow tires on). They would make that same thumping noise almost like they're skipping on the pavement, and it happens even at like 2 mph. It definitely freaked me out when I first started hearing it but did some research and it's common with summer tires in cold/cooler weather (I notice it especially in the mornings leaving for work) And yea on tight diameter turns with the steering wheel turned all the way they would do it a lot. Not aware if it causes any strange tire wear, but in any event if you hear them doing it just make sure to drive slower since your traction isn't nearly as good as it would be in warmer weather.
