Yes, believe me, I'm completely hooked. I find myself often thinking "I don't always spend 9 hours straight online, but when I do, I'm researching about my car." I spent a few hours looking through TireRack's reviews and options and I narrowed my choices down to two different options, but I figured I would ask the Miata gang as well for their unique input. Chances are that someone with a powerful but heavy Camaro who bought the same tires would have a different experience with it than us. I looked for tires with at least 240 treadwear, AA traction rating, less than 25 lbs per tire, less than $650 for the set (preferably less than $550), and consistently positive reviews. I looked at the turn-in and cornering balance as well. I narrowed it down to Pirelli P Zero Nero or (after listening to Brian's input) sticking with the stock rubber (Bridgestone Potenza RE050A). I found a few similar Bridgestones today, such as the Bridgestone S-04 Pole Position. After starting this thread and reading Brian's responses, I thought back about all the previous tires I've had and I'm realizing how right he was about the different characteristics of each tire, not just grip.
