The syock XGTs suck, and you will truely realize that when you get good tires. I got Bridgestone Potenza RE-730 205/55. I love them to death. Paid $97 a tire, good price. Awsome in rain as well, better than XGTs even in rain. Get them you will not regret it, as long as I have 15s on my Si that is the exact size and tire I will always get.
