OH MY GOD MAN,
you really, but really need to add air into that rubber, What was the tire pressure at the beginning of the session?
did you take the tire pressure at the end?
it really looks like you had no air in them and as a result this happened. a common mistake it to lower the pressure of your tires before you start on the track. always start with more than the usual and work your way down from that point.
remember that you can take air out as the session goes on, but it is really a bad idea to add cool air into a tire warm of the track. i use nitrogen when i go to the track and it works great, you can get it at almost any new tire shop and it controls the temperature far better.
remember to take the tire pressure after you have ended the laps, in an ideal world all of the tires would be at the same pressure. if one is higher that the other then you can take air out to match the rest. this will give you a more even balance and you will see that the car handles better.
of course everything that i tell you is subjective, this is just my experience as a races car driver and i know everyone has there own opinion, but in street cars this has worked for me... also this is advised based on the assumption that the cars suspension is in stock condition and that you haven't been playing with camber or toe setting.
hope this helps,
Willie
P.S. use shoe polish to mark your tires before you enter the track, and see at the end if the marks are still intact or how far are they gone.
