Michelin Pro4 Endurance 28c, I bought them as I was getting sick of sidewall failures with Contis (GP4000/4Season/UltraGatorskin the same story with all of them).
Two years and they are still going strong with only a few tread cuts. They are also safe on nasties like road markings and drain covers. (My normal ride routes take in plenty of cattle grids and flinty roads but generally no thorns, fwiw.)
