Personal Experiences and Reviews:
If you have personal experience with a tire listed, please list the tire and size and how long you have been running competitions on the tires. Also, please give a short review of your overall thoughts and if you would buy them again or recommend an alternative tire. Please do not post pictures - not necessary, and I want to keep the thread simple and faster to load for all users.
Example,
"Tire: Falken Azenis RT-615
Size: 225/45/17
I purchased these tires to run in my STS class...
..
..
..
....I would highly recommend these tires for STS competition."

*If there is any information I left out that you feel is pertinent, please PM me to let me know (such as another vendor, a tire no longer made, safety information, etc.). If a tire is not listed, please PM me the information so I can add it; however, remember that the focus is on competition related tires dealing with road racing, autocross, and drag racing - not street performace (a separate summer tire thread should be made for that).
