What race tires?
For most purposes, the same tire I train on, Conti Gatorskin folding. The folding are about 100 grams lighter than the wire Gatorskin, making them a very light tire indeed. I'd say they wear well, but they hardly wear at all; I get 2000 miles out of a set without trouble. They stick really well as long as it's not wet (caveat: they are treacherous as hell on damp roads). Plus they are tougher than nails, literally. I've only flatted twice on them in the last couple years. Awesome tire for a mid-range price.
For champagne racing on nice surfaces, Vittoria Corsa Evos. Sticky as fresh bubble gum, 290 threads per inch make 'em softer than silk to ride on, and they weigh next to nothing. Not real durable and I wouldn't ride these on the Northeast Branch trail over the hypodermics and broken glass - not unless my goal was to meet the interesting local people who keep the multi-use trail well stocked with used needles and busted 40 bottles.
I'd consider racing my cheapo Tufo T-22 tubulars which I'm training on right now, but not if the ground was anything other than bone dry. These are supposedly the toughest, nastiest, worstest, heaviest tubies around yet they provide a sublime ride and are lighter than my lightest clinchers. When they give out I'm going to upgrade and see how a really nice (e.g. mid-range, race rated) set of tubies rides. I'll let you know.
Other tires I've raced with good luck: Michelin Pro Race 2 - light, sticky, short life. Decent wet weather tire. Serfas Seca - good crit and rough industrial park tire; sticks okay, very flat resistant. A little heavy and rides a bit rough, but you can train and race 'em. Conti 4000s - good tire, nothing particularly amazing or bad; just proficient. Specialized Armadillo - like racing on the wheels of Fred Flintstone's car, except they last longer and are possibly harder.
