AJ recently won T1 in his Phoenix Performance mustang, the car ran 180 through the tri oval just prior to braking, which was sort of a first. During the test days the car blew a right front tire damaging the fender and wiring harness (and fortunately prior to my arrival). Hoosier made some recommendations, which we may..or may not have followed.
The point is this, in the advanced tire topic thread I was trying to get you guys to create a scale or gradient of tire pressures vs ambient air temperature, a few did, with good results, the others...well not so much.
You should be running nitrogen in your tires and, if you follow the recommendations on that thread you won't need more than a 10 gallon tank to take to the races, the big bottle can stay at home.
During the practice and qualifying sessions we cultivated a set of scuff tires for the race, the day of the even we still weren't decided to run the scuffs or stickers, but decided to run the A7 scuffs. I figured the temp / pressures out, basically exactly according to the method in that thread.
The tires lasted 14 laps and AJ ran away with the race, the following BMW blew the tires off the car and Mustangs finished 1,2, and 3.
I doubt the tires would have made more than 1 more lap, there were thumb size blisters all the way around, IF we (me) had failed to create the correct temp/pressure graph, IF AJ hadn't done a great job of saving the tires, IF the race had been 1 more lap and IF the temperature had been 10 degrees higher, we wouldn't be celebrating, we might have been scraping the car off the wall.
Just sayin'
