What is the cold pressure for 20" P Zeros for 30 minute DE sessions? Last time out I started with owner manual cold settings, but within 5 laps in 80 degree weather they were in the high 40's and got squirrely. Also, what PCM tire setting. Comfort or full load? Thanks.

I had a similar experience and also started out with the full load cold settings of 36 front/44 rear. When it got a little squirrelly I dropped the rears two pounds and it made quite a bit of difference.

Just try and figure out which end is loose and drop those tires a couple pounds each time until you regain traction.

I'd suggest you always run the tires at the comfort pressure, partial load. I ran them at 33 front/36 rear year round, and cut them to 30 front/32 rear for the track. They don't like anything above 39 on track.

I changed to Michelin Pilot Sport Cup 2 this last tire change, and WHAT A DIFFERENCE they make on track, yet are great around town, too.
