Firestone Indy 500

[The Radium King]

spent the day at the track with them. forecast was for thunder, lightning, torrential rain, cats and dogs falling from the skies. so, i left the hard-worn nto1's with no sypes back in the trailer and took the street tires. bad decision. sun shone the whole time, and i added 7 seconds to my best time.

what i found is that they heated up way too quick, and totally lost their composure once hot. spent the day playing with pressures to see what worked. started at 34/36, went to 32/34, finished with 30/32. nothing really worked. they made me sad.

It sucks to buy a new set of tires and find out they're not good, esp track tires. You can't wait to wear them out to get something new, but remember that $1K you're about to blow.

FWIW, I just put the Firestone's on my new to me 2001 Boxster S.

I tracked a '99 996 for several years. Not the exact same experience, but close enough to comment. Coming in off the track, you want to shoot for around 40PSI.

Unless you are running in PCA Green group, these tires will suck. If you are blue or better, get something like a Bridgestone RE-71 or Hankook R-S4. They will handle track temps and be a lot more fun.
