Please help! I have had street 205/55/16 tires on all 4 stock wheels. The Yokos are now gone, RIP. Now I am moving up in the DE field and ready to make the next step for a track/street car (not an ultimate track car!). I have a 3.2 l engine in the car now. I plan to open the checkbook for suspension work (sway/torsion/adj. shocks), but immediate need is tires (one is destroyed):

What are the best options for wheels/tires without modifications to the car?
What are the best options for wheels/tires if I make minor modifications to the car?
Where can I go to read up on what all the numbers mean and how they work for wheel sizes, etc.? (and learn enough to be dangerous!)

A BIG THANK YOU TO THOSE WHO REPLY AND SHARE YOUR EXPERIENCE!
