I had one set of Ultrasports and they punctured repeatedly, nearly every time I rode that bike. They really are rubbish. As a skinflint at heart it is the only time I removed tyres that still had a lot of life in them.
(And I just know someone will reply and say they've rode the same set for 10,000 miles without a puncture!)
