Perhaps "stability" means slow to change direction, however, the rear tire design still has a high level of ultimate grip? With the variable tread compound design I wonder if they don't use the "softest" compound (or smaller width) on the outer tread blocks - this would slow down turn in (give the feeling of "stability") but then as you continue to load the tire it's still capable of generating a high level of lateral grip.

During my turn-ins at the track I generally stay on the brake a little longer (trail brake) and add some steering input before I fully release the brake initiating some rotation to get things going. Driving on the track is much different than on he street as you approach the limits |

That's what I get out of the email. It sounds like if you use a tire designed for the rear on the front you'll get understeer at initial turn-in but it has nothing to do with steady-state and/or mid-corner handling/grip.

Now on my old e46 M3 I did notice if I used a staggered PSC setup the front end would turn in a bit quicker than when I used a square PSC setup. However, overall lap times were lower with the square setup. |

I need to replace the OEM PS2 tires that came on my car finally (been running winters during the cold months). But, as you can see in that link, tirerack won't have my size until mid-May at best. Anywhere else I can get OEM 18 inch sized PSS? Or should I just call up some local places?

^ I just inspected the tread on all 4 and it's very evenly worn after about 3k miles and a few track days. Keep in mind this will vary with your driving style and the size and type of rubber you run as well as the pressure you have in them.

I run a dedicated set of track wheels and tires so I do see slightly more wear on the inside of my PSS street tires with the increased camber. It is barely worth mentioning though and definitely worth the handling and tire wear advantages on the track.

I ran 18's and the wear was terrible everywhere... outside chunked, inside worn, the middle tread was worn to an angle. For some reason the 19's are wearing so much better. completely even. I'm using PSS's for both street and track. Sometimes I throw on a set of slicks on my 18's |
