I finally replaced the Goodyear Supercars with Michelin Pilot Sport PS2's.

What is a good starting track pressure? This is a '06 Z51 with Z06 rear bar and was using 31F/32R with the Supercars.

Thanks in Advnace

z060ntrack, I don't know the answer to your questions, however, I am very interested in what you think of your new Michelin Pilot Sport PS2's. I am thinking about purchasing them tomorrow. I also have the 06 Z51.

about 32-34. watch out, they get greasy after about 15 minutes. otherwise decent street tire to use on the track.

I have an 05 MN 6 Z51 coupe, HAWK DTC 30s all around. Bought a set of PS2 non runflats in Oct. 08. Have about 12 track days on them. Usually start out 26 F 27 R. End up around 34 F 35 R. These take about 1.5 laps at Putnam or Mid Ohio to get warmed up. When warm, grip is pretty good. Ran in a driving rain at M.O. this summer...good grip when driving off line at 60% (came in when the map pockets below the arm rests were full of water! )

Borrow a tire pyrometer (the kind with the probe) for a buddy to check tire temps mid session. Pit in as fast/hot as you can with no cool down. Have him take tire temps at 3 places across the tread (outer, middle and inner.) Read these after the session to determine if you need more or less pressure. Maximize contact patch.

These are a great "compromise" tire - one you can drive to and from the track on and have good grip while on track. These also make plenty of noise when on track (like a good street tire should) so you can listen to them "talkin' to you" about how you are driving in the corners.

Plenty of tread left. Flipped them left to right for the last 3 day event and began to even out the tread wear on the center tread (the one with no sipes), especially on the fronts. Kinda pricey up front, but I will likely get quite a few more sessions out of them next season.

Good luck!

I didn't get to test them out on the track becuase it was to late in the season. They definitely are more supple without the stiff sidewall of the Supercar EMT. They seem more responsive and the turn in is slightly better.

I haven't tracked my PS2s, but they have more than done me right for AutoXing. They do bark just enough so you know where you are in grip. I'm still fairly new in the game so I'm not adjusting tire pressures just yet. These tires will hopefully see Sebring next summer though. Good luck out there!

Excellent tire for both street and track

I used on a c5 last season and would recommend 29/30 to start

Aim for max 36psi and hottest

I was recording tire temps in the mid 60s/low 70s Centigrade

Puling about 1.1g max
