Dunlop D209GP's I'd go for if you can find them, most shops will try and sell you the GP Racer instead but it's not in the same class. Like Fontyyy says, the Maxxis road legals are good also, and very cheap to boot.

Definitely stick to the standard sizes unless you have wider rims, as you'll mess up the profile, but you should know that from your TZ riding days...
