2008 FSRxc Expert - Street tires?

Hey all, learned a lot on here, so first, thank you to all the members... Need a little guidance...

I am starting to expand into triathlons. I don't have the money to buy a whole new road bike, and I am not in a position of winning any race any time soon. So basically making my FSRxc street friendly would suffice for now.

With that in mind, what kind of street tires are decent for this bike? Any suggestions? Also, any tips from any triathletes here are more than welcome... :-D

Thanks for any input you all may offer, thank you!!
