The car came with Continentals. They are still on the front. One of the rear tires had a leak for some reason.

We went into a reputable tire store and they broke the tire down and discovered an imporperly applied patch from a previous puncture. They would not repair the repair, so the tire was junked.
They had a pair of Kumhos in stock in the right size. The other Continental is sitting wrapped in my garage and will go with the car when it's sold.
