OK KAHBOOM, Middle lining? The tread on any Michelin Tire ( known in Michelin as the KM) is all the same compound. The tread ends in the shoulder area of the tire. you can see this by a slight coloration line in the shoulder area of the tire. that is where the sidewall rubber ( FE "flank exterior") is over lapped with the tread (KM).
Side note KM actually stands for Kelly Michelin. Not sure if it was the daughter or niece of one of the Michelin Cousins.

"Michelin says the PS2's tread is composed of two different compounds. The outer two-thirds of the tread has a rubber compound that's biased to provide good dry traction; the inner third has a different compound that's skewed toward wet traction."
I am sorry I called you wrong on this one. Now i am interested how the extruder handdles these 2 compounds in the manufacturing process. See you learn something new everyday. Once again sorry for saying you were incorrect.

I have to retract my statement I made to KAHBOOM. I was wrong. I was doing some research and he is correct. I have worked building tires for 4 years and my fater was head of QC in the michelin plant in Bridgewater NS. I have never heard of this until now.

bump for any updates AND pics!
I'm thinking to change out all four with the Pilot Sport A/S tires: 245/40 in the front and 275/35 in rear on stock OEM 19" rims

There are actually three different compounds on the AS. And the more aggressive dry compound is on the sides with the all weather compound in the middle.
I guess that is why the Pilot AS is so expensive too. But I loved them on my G35. The inside ribs wore a little quicker than the outside but that was ok with me for the benefit of having those tires.

I'd be interested n getting your impressions after several weeks of driving. When it's time to replace tires I'm considering going wider on the factory wheels as well. 255/40/19 front with 275/35/19 rear. If there are no clearance or rubbing issues (I doubt there will be) this combo is < 1% difference in circumference from stock sizes but significantly wider. It also gives me choices other than the OE Potenzas.

^^ +2 to both posts above
Have to go wider for more options in tires, i was thinking to get the same size u mentioned.
I thought i could make it the whole summer with the OE tires but i have 15K miles now and looks like i will hafta replace by mid summer.
NEED SOME GOOD SIDE VIEW and CLOSE UP PICS! ...plz =) thank you
Interested in seeing how ride height is affected, wheel gap, and just how "meaty" the tries look.

225/45/19 = 4" sidewall, 13.5" radius, 27" diameter, 84.7" circumference, 748 rev/mi.
255/40/19 = 4" sidewall, 13.5" radius, 27" diameter, 84.9" circumference, 746 rev/mi. Speedometer reads 60.1 MPH when actually traveling 60 MPH.
245/40/19 = 3.9" sidewall, 13.4" radius, 26.7" diameter, 83.9" circumference, 755 rev/mi. Speedometer reads 59.4 MPH when actually traveling 60 MPH

Plus zero is a larger tire on the same sized wheel maintaining approximately the same circumference as the original size tire and wheel combination by using a wider tread and lower profile tire.
