Drag radials
Finally got rid of my runflats and went with a shorter MT D/R. 245/40/18
Thinking 20 psi should be the magic number but any input would be appriciated. Car is lightly modded, exhaust/vararam/tune. This will be my first run with a tune on the car. Prior to that the car went 12.92 @108 with a 1.97 60' spinning off the line. Am I close to the PSI I need with 20 psi. It feels good on the street.

That's a reasonable place to start.
Run as much pressure as you can without excessive wheel spin.
