Front tire PSI recommendations?

[Airborne5.0]

Hi everyone,

I have Firestone firehawk Indy 500 on a stock wheel (pp1) in 245/45/19 up front and nitto 555r2305/45/17 on vms 17x10 in the rear at 28 psi.

my firehawk indy

many one with a similar setup, what psi do you run your front tires?

heading to the quarter mile tomorrow and will be my first time running this set up. I plan on airing down to 20psi cold in the rear.

10% less rolling resistance.

interesting! What does that translate for in terms of the time slip?

Realistically. Maybe .000458 seconds.
