The Highway tires. It's a marketing description and different models/manufacturers will have different results (YMMV) but generally "highway" tires will tend to have a ribbed tread design with circumferential grooves being more predominant than any axial grooves. This helps them roll in a straight line with much less noise/resistance but hurts cornering ability.
Touring tires would be a good mix as they try to be more of an all-around tire for vehicles that do turn and would probably have better wet traction than a highway tire without a significant increase in rolling resistance.
Sports tires sacrifice everything for traction. They'll be heavier to support high side-loads, softer for better traction all around, and the tread blocks will be shorter to prevent squirm (raise the confidence near the traction limit) but will therefore reduce wet handling and tread life. Probably the highest rolling resistance tires you can find.
