Just installed a brand new set of RE540S Type R (hard compound) tires on all 4 corners of my teg. I'll be using them on track soon.

I'm using my normal road going pressure which is 2.3 bar (33 psi) at the front and 2.1 bar (30 psi) at the back.

I took a quick glimpse at Bridgestone's catalogue and for track they recomend 1.6~1.8 bar (23~26 psi) at the front and 2.0~2.4 bar (29~35 psi) at the rear
Are they completely bananas? Or am I missing something?
