If you are refering to tyre compounds then its pretty simple:

Dry = mini spike yellow compound rears and either yellow staggers or cut staggers on the front. The cut ones have more bight and depends how you much front end you like
Wet = Ballistic Buggy mini spikes green compound on the rear and then the fronts can be as per above or balistic buggy mini spikes green on the front too

Except for Herts, which I havent been to yet, they are all astro like ours
