I'm pretty sure you won't get the A539's in a 10", I think 12" is the smallest I've seen, I could be wrong though.
Anyone who says that the A008's don't hang on in the wet hasn't driven on Bridgestone SF226's or Falkens(I don't know the tyre's name) in said conditions.
The other tyre of choice atm without spending big $$ is the Dunlops. I haven't driven on those so I can't comment on their abilities, they do look the goods though.
The Bridgestones will nearly last forever, I have been driving on those for the last 2 1/2 years every day and are only now getting to the wear indicators after about a total of about 50,000km with a frequent run through the hills.
The Falkens are the second best option they don't last as long but give much better traction. One person I know tossed his 20% worn Falkens for the A008's just because of the difference in the wet. And he really likes to drive his car. (remember the been chased by an S vid? that's him in the S)
And of course the Yokohamas are better again but with the cost of higher wear. They are the tyre of choice for me where a budget isn't of real concern. I have driven on them, and know people that do.
Lets face it grip costs money and longevety. There are better tyres but i don't really want to spend the $150ea+ price tag. $100ea is enough. If these tyres last a year I'm happy.
I also have some A008's to go on NAV on friday and I can't wait
