Track day tyre pressures

[Car Mad Dave]

Road use has been covered quite a bit but I’m struggling to find much experience for track settings (I know there is a track setting on the door pillar).

Specifically, what have track day warriors run as a hot pressure when using the stock MPS4 tyres? The side walls are softer than say a Cup2 tyre so careful heating up from cold and not overheating should help manage excessive shoulder wear when using the MPS4 on track. Any advice greatly received.

I use the A110 a lot on track with the Michelin PS 4 tyres. Is use 2.2 BAR (front & rear) hot. Me personally I don't exceed 2.2 Bar and don't go below 2.15 Bar (measured hot). BAR <-> PSI conversion is easy found online

Thanks Franzino.

I have just finished my first track day in the A110 and found 2.15 -2.2 bar (31 - 32 psi) hot about right for the PS4 (Pure size) tyres.
