A lot of folks will have
their favorite tires and will recommend them. But what you may want to add to your question is what type of driving you will be doing. Street use only? Occasional autocross events, maybe a track day once a year?? What sort of weather will you be driving in, dry pavement, wet roads, ice or snow?
There are a wide variety of tires by brand name and level of performance in dry and/or wet conditions and of course cost will also play a big part in a selection.
For my personal suggestion, I have a set of Bridgestone Potenza's (RE730) on my 92 vert that has seen both dry and wet pavement, a couple of seasons of local autocross events and 3 track days at Portland (OR) Int'l Raceway where the track temps reached 130+ degrees. With about 30K miles on them, they have about 75% tread left. They are very quiet on the road and are much stickier than the original Goodyear GS-C's ever thought of being.
