Any sports touring tyre will do great, depends on how much you want to spend. They all have more grip than a Vstrom has ground clearance.
Michelin road 5-6 range are the best but the most expensive. Pirelli angel gt's are good and reasonably priced, as are Bridgestone bt23's.
If I was using the bike every day I'd buy the Michelin's but if a weekend nice day rider I'd buy the gt's are the stones.
