Michelin Super Sports - Track Tyre Pressures - M2
Hi All

Anyone have experience running MPSS's on track on an M2 (or any M car)? Prepping for a track day and wanna get an idea of what cold pressures to run.

Many thanks

Run stock pressures then check after each run and adjust accordingly

Tyre pressures should be higher than normal road use, to prevent "rolling" of the tyre on the rim and basically just chunking the outside edges to death

Thanks - ran 2.0 bar all round in the morning session. At end of session pressure was up to 2.7, and PSSs have an odd greasy feel when too hot.

So dropped to 1.8 for next sessions - TPMS notifications came up but was running steady 2.2-2.3 bar hot - felt good.

Don't know about this, would mean you running 3.0 bar plus when hot (70 degrees). You'd have no tyre centre left nor grip.

I have had a car go up to 3.5bar(hot temp) grip was less than optimal(not by much) but it saved the tyre, normal road pressures on Michelin and you'll go through a set of tyres in a single day due to the edges wearing down.

In my case, I am not competing etc, track day is for fun, so you not looking to shave tenths off of every lap, sacrifice a bit of grip to save the tyres, or put cheaper semis on and go ape shit

Back when the Audi Advanced Driving course was active, we were told at Gerotek that they run the S4s at 3.0 bar when they do high speed runs and the skidpan. They advocated high tyre pressures for performance.

Thanks! Car was quick - also quite neutral, more traction than expected, and M Performance brakes were great!
