TIRE RECOMMENDATION

Yokohama AVS ES100. I love these tires on my Integra and will not hesitate to put them on my mustang when the time comes. or if you don't get a lot of heavy rain, the old Falken Azenis tires are pretty damn sticky ... huge tread blocks. they wear quicker, though.

I'm going to have to agree with brian, though. you won't see the full potential of good tires without some kind of LSD/locker and maybe traction bars. the rubber is only good if you can keep it stuck! [of course, I don't know if you already have those things, just assuming].
 
I run BFG radial TA's because I want long tire life with good looks and performance. You want low life and a sticky compound. Look at the tread wear rating on any tire and get some with a low number which means softer rubber.
