If you are 95% road I highly recommend the Specialized Pathfinder Pro's. I ride 38mm, but they do have a 42mm version of the tire. Great tire for the road and good on the dirt too. I ride them tubeless and over 2 years I have never had a puncture issue. I did slice a sidewall open once but it was my fault for being too lazy to correct my line and going over a metal drain grate at about 40mph.
Unfortunately the Pro's are in the $50+ range. There is a Pathfinder Sport that is very similar (slick center ridge) and cheaper than the Pro - I've seen it for about $35 online and it comes in a 42mm version. It has 60tpi instead of 120.
