Continental Speed Ride. They are 700x42C, but in fact measure 38mm on 19mm rims, and that's in line what I've read from others. Have had them for a bit over 1K miles, so far I like them a lot.
Off topic, but I think focusing on traction is exaggerated when talking about recreational/fitness riding which is usually the type done on hybrid bikes. I personally very rarely experience situations where I've felt a knobbier tire would have made much difference. That said, I've ridden in mud and snow on near-slicks all my teen years, so I know what to anticipate from different surfaces and am pretty confident in my skills.
