Michelin PS2 or PS3?

[hqduong]

I have a set of Michelin PS2 now but it looks like I have to replace the rear ones soon.

I am debating if I should wait and replace all of them with the PS3s, or just replace the back ones right now with PS2. I track the car heavily.

I know the PS2 has been out for a while, and I have been impressed every time Michelin does a refresh of their tires, but I'm wondering how much of a difference will I see with the PS3 vs PS2? Any ideas?

Anyone know the release date for the 265/40R18 sizes?

If your tracking a lot I have two thoughts...

1.if you only replace the rears, stick with the PS2 so you have the same compound on all four corners.
2. If you decide to replace all 4 tires, try a set of Yokohama AD08 really.

I am a big fan of the PS2's, but I really like the ADO8's and I have had many track junkies praise the Yokohama over the Michelin.
