a single pass would do, u can roam around for the whole day with that....and mind it, its a big area, reach early so that by the end of the day u can visit all the stalls
The tyres are not that bad and are in no way uncontrollable if its in the right hands. It's more of a rider thing then the tyre. I agree it might not be the best but it's not the worst either. Ride it for 10-15k and you can switch to the ones of the Dazzler for the rear.
PS: You need to be extra cautious while riding/taking corners in wet conditions.That's about it.
