Well with no idea what you want for a kind of tire, its hard to say.

Personally I havent seen much of the G-max so no opinion there. So if it were me I would going with a conti DWS or the sport contact. Bridgestone and Michelins tires you are going to pay way more, like the potenza and A/S plus. And to me you never get your moneys worth because they wear so quickly and tend to get cupping issues with being directional. I'm sure if you drive it like sports car everyday that wear wont happen. They are other tires out there to choose from aswell, but it depends on what kind of tire you want.
