Drift tires, in general you want something that won't chunk up and delaminate. I've Had good luck with Kenda tires on my drift car. They're pretty cheap and have decent traction and actually last a while. I've also used Federals and Nexan, which are also pretty good.
Word of advice, use wheels in the back you don't care too much about, if a tire goes down it's likely going to chew the wheel lips up.
If this is your first time drifting, this might not be the best car to learn with, you might want to start with something a bit cheaper.
