I don't know if this would be appropriate for you - but if/when you decide to go with skinnier tires - I just got some Continental grand prix 4 season tires & they're great! I've rode on Conti's for the last ten years, so I'm a little partial to them - but these are great for sand, mud rain, etc.

One thing about wet - know that when you go through a wet spot, your tires will pick up glass & other crap that might be in the bike lane & hang onto it a little longer. So, if you have to go through water, try to avoid that lovely pile of windshield that the EMT's so kindly swept into the bike lane!
