I came across this very good read posted on the High Performance Driving & Racing Enthusiasts Facebook page on how to properly select a tire for performance. It's actually slightly contradictory to what we think is correct in selecting the proper tires and sizes for our cars. I highly recommend checking this out, maybe even making it a sticky if everyone else agrees.
