Hutchinson tires. I just bought the UrbanTour+ that is puncture proof. 700x32 is my size. It has very stiff sidewalls and has a max inflation of 94psi. Compared to my Kenda Kwick they have far less tire squat and roll very nice. I was sold a set of Serfas Touno tires last weekend and it fealt like I was riding on flat tires they squatted so much and I had four flats in five days- just too thin and flimsy of a tire.
