I would go with the Conti SportContact2's. I've had them on some other cars and they are decent tires. Everytime I buy Pirelli's they seem to dry rot or have quality control (like sounding like a bad wheel bearing) issues down the road.
I would also check the "build date" on the tire sidewall. Tires are only "good" for five years... so don't buy some tire that has been sitting on the shelf for years. The build date is a four digit number with the week & year the tire was made.
more info on tire build dates...
