Experiences with different tire pressure values
Below a picture of the 1M tire pressure specs.
What tire pressure specs do you use (Summer/Winter/Track) and what are your experiences with different values ? (soruce: http://www.1addicts.com/forums/showp...92&postcount=6)

Just summer or pseudo winter here, basically city driving plus some highway and once a week a spirited back road drive, so: I was using exactly those factory recommendations with stock PS2s, now with PSS I am going one more front and rear (2.4/2.3). I will try factory recommendation one more time with PSS though, to make sure what I like more.

I'm running 18in M3-wheels all year long. I started with 2,1 and 2,0 for the road then I had my KW-DDC and went up to the 19in recommended pressures of 2,3 and 2,2.
On a dry track with normal temperatures, I will decrease by 0,4 bars front and back, to allow for heating. On a wet track, pressures should normally be increased above recommended stock pressures. But in all honesty, I just kept driving as it started to rain, as my track time was limited... Ho wait, that's maybe why ended up spinning ?? Last edited by LotusBoy; 10-28-2012 at 04:15 PM..

Since I drive most of the time in "slow" conditions I will keep the factory pressures for some time. You guys can make your own decisions depending on your style and conditions, but I recommend for anyone who will start with a brand new SS set, start with factory pressures and play around after the break-in period (approx. 500 km or 300 miles).

At least for use on track, I set tire pressures based on the tires optimal hot pressures.
For the Michelin PSS, this is between 37-39 psi. Since I pick up 8-9 psi on track, I start with cold temps around 28.5 psi and check tires' hot temps immediately upon coming off the track. For use on the street, I generally set the tires at around 32 psi. Neil |
