Now I know that there are many many many posts about tiyres but from what I have read no one really goes into detail as to how these tyres handle in the wet, now i am looking at changing my tyres and being that i live in scotland it is wet 99.9999999999999999999% of the time so it is beneficial to me that i get a set of tyres that will work well in these conditions.
Any advice would be greatly appreciated.

Sorry, don't know much about tyres, but could you tell me how to catch aand cook a haggis?

Good tires for wet conditions are usually labelled as sport touring since touring guys ride all year they'll need a little more wet traction then the dedicated supersport track-type tires. The stock BT-45's are pretty decent in the rain so are michelin macadams, I'm speaking from experience, and if you really need to I've had good experience with metz lasertecs in the snow 

Well, you might look at the Avon Roadriders as I put on a pair back in July '08 and with almost 7k on them through all types of weather (hot, cold, rain, snow, etc..) and they work great. They're a sport touring tire, from what the vendor told me when I bought them, they're in between a Pirelli Sport Demon and a Bridgestone BT-45. Take that for what it is, but I've been happy with them.

Wet all the time, eh?  Sounds like Buffalo!  You want tires with rain grooves.  Use a little imagination when comparing tire treads, and you'll see that some are designed to channel water away from the center of the tire and some are not.  The other day I was looking at the IRC rear.  That is an example of a HORRIBLE tread for rain.  Dunlop didn't look much better.  I think Dunlops are expensive crap and their factory is in my hometown.  I'm supposed to love them, but I don't at all.  Avon Roadriders looked much better for all weather traction, and they're not super-expensive.  Actually the Kenda 671's look pretty good too, and they're cheap.  I like cheap.  I work in the private sector.  That means I'm poor!

Avon Roadriders.  i have 18k on the front and 12k on the back.  i ride in any weather and they do fine.  that is at freeway speeds mostly.
