My favorite tires are the Avon Storms. They're perfect for my riding style which is mostly highway. They're excellent in the wet, too. I've been caught in the rain many times before and the roads felt like they're dry.
They last a long time, too. I think I get more than 10,000 miles out of the rear. Mind you, I don't abuse them and I don't ride hard at all. Here's a pic of the rear with maybe 5,000 miles on it.
If you live in a place with not that many twisties around you, I highly recommend them.
I can't wait to try the new Storm 2 Ultra.
