Main things to consider are
1. Tire use (track, AutoX, street, etc.)
2. Your capability (newbie, experienced, advanced, etc.)
3. Your goals (hobbyist - a few track days, autoX events per year; Track rat - every weekend; a better handling car on the street and looking cool)
4. Your budget

When you can get a 3-5 year outlook, this decision becomes easier to make and to live with. I made some really stupid decisions when I first bought my car and have been living with the consequences because the cost to replace (i.e. - make a different decision) is very expensive.

Once you understand your goals, you can narrow down the tire types you are likely to want to try. Once you have this list, try to drive the different options for your given setup. Then, make sure they are available for the size options you are considering. I just made the move to 18", and in the process eliminated the Goodyear 3Rs - a tire I hadn't tried until after I bought my 18" setup and now painfully regret yet another rash decision. The Supercar 3Rs are an insanely good tire and I never gave them a shot while trying almost every other tire out there and settling on Toyo RRs for my track based on cost, performance, and longevity factors. I have the option for Hoosiers with the setup I have as well, but the cost to longevity is terrible compared to the Toyo's (but the performance is similarly pretty far apart). I did not realize just how good the 3Rs were until I drove them recently and wish I could take my decision back and go with 19s. I'd still have Toyos and Hoosiers as an option, but I'd also have the 3Rs....
