458 Best Tire Pressures for Michelin Pilot Sport 4 s

In NL (Europe) 2.0 Atm front, 2.4 back ...

 

I run my 2015 Spider at 30 psi, Front and 29 psi Rear. I've experimented and found that this gives me a comfortable ride but still with plenty of grip when spirited driving.

 

Same. These are the settings on the door pillar and seem to work well. The car has more understeer than I’d like for the track, though this is good for public roads where you can encounter more surprises and don’t have room to drift or keep the right pedal down.

I did do a Track Day during the Summer and for that event I increased pressure by 3 Lbs cold at each tire and I thought the car felt very neutral. Tire pressure is easy and free to adjust so experimenting can be interesting.

 

For better grip for a track day due to tires gaining more pressure that street driving you should decrease cold pressure instead on increase. Hot pressure with stock alignment of ps4 tires should be around 36psi max. Usually on track beginner to intermediate drivers you will see around a 6-7psi increase from cold. After each session you should be bleeding air out to keep hot psi in check.

 

Ditto. 30/29 Street. 27/26 track maximum. (don't go hard the first few turns)
