The norm for astro is yellow minispikes in the dry, Ballistic greens in the wet...having looked at our astro, I see no reason for this to be the wrong choice!
And in 2wd the front tyre of choice currently is the cut stagger...in either full or low profile.
At some tracks the wet tyre choice varies, but I'm always a little dubious...to be honest, in the wet no tyre has much grip...so it just comes down to which one works best in your own mind...or your own tyre collection!
Minipins might also work...but to be honest, with Astro, the tendency is try and find less grippy tyres rather than more grippy ones...the new 'evil' on track will be grip roll rather than the spinning out the gravel previously gave us
I also intend to play with other manufacturers as well once we're running and settled...there are a couple of other tyres around these days, dBoots being one, which may offer a better compromise in grip vs wear rate. The only real reason these don't carry more favour with the top drivers might be the control tyre ruling at nationals...but for club and regional it's open so wouldn't matter at all!
