Any comments on the new Hoosier 255 now that some have tried them

Took a close look at mine today. We were close to cording the pair that were on the front for Saturday at El Toro; 24 total runs in the low - mid 40 second range. We swapped them to the rear on Sunday; 12 more runs. I'll be having them flipped soon.
It's odd that the outer front corners are shaving off at a 45 deg angle. The rest of the tire isn't worn much. I've never seen this before, ran other size Hoosier A6s all last year without issue.

(now that I've said that, there'll be 300 entries, we'll only get 3 runs and finish at 7 PM...
)

My email's with Hoosier say that nothing is going to change with the tire.
They regret that not all cars will get good wear with the product.
We were at near 50psi for pressure and are now going into the 50's.
That is on a Cobalt though.

hmm, thought I had posted the info previously
ran low-mid 50s on asphalt and they still rolled over too much, ran high 50s at the Wendover Pro concrete, the problem was not occurring as fast, but it was still going to happen, front grip was fine at that pressure until going over the limit and then the tire was not quick to recover
I won't buy another set of 255s, the 285 Hoosiers mount up pretty easy on 8" wheels, much easier than 245 V710 Kumhos

Can those who have had issues with the 255 A6's post up the manufacturing date from their tires?
Keith Scala will be adding some interesting info to this thread on the 255's he's running on his moton equipped '09 RX-8 sport with only ~-1.3 degrees of front camber.

Chike -
I don't have the first production run 255's A6's close by to give you an exact date, but they would have 4th quarter 2008 dates.
The 255's John and I tested for this months Grassroots Motorsports article (August 09) were also from this batch. As mentioned earlier in this thread, Hoosier has not planned any immediate changes to the tire.
Although the tire wear appears to be accelerated at the shoulder ply/ tread cap junction point, we (and others-EDJ!) have found the 255's to be very competitive on the clock. On surfaces that are known for high wear rates or drivers who tend to drive through an understeer condition, I would recommend the 285's on the front. The 255 wear rate seems to be much less of an issue on less aggressive surfaces like the Finger Lakes asphalt or our asphalt test track.
John and I have continued to experiment with 285F/255R combo. It has some pluses and minus depending on the course design, but it is another viable option to try.
See you in Toledo -

Chris,
Keith had a set at the Finger Lakes NT which had a build date of the 11th week of 2009 which had ~17-18 runs on them by the end of the weekend, which showed no unusual wear whatsoever. What's remarkable is that he runs only 34psi in the front on a car with only ~-1.3 degrees of front camber.
On the Fedex asphalt, one of my local competitors bought a set of 255's earlier this year (has had them for a few months now) and his tires are showing the much described groove of doom forming along the outside edge. He runs -2 degrees of front camber and runs pressures in the mid 40's.
I'm wondering if Hoosier quietly fixed this issue or if there was an issue in the production of the 1st batch of tires.
P.S. Won't make Toledo this year. The DC Pro will be my last national event both Nats. See you in Lincoln!

Here are photos of a rear. I used 34 psi in front and 32 psi in rear
Photo 1. less rubber pickup
Photo 2. less rollover
Photo 3. a fun photo
Photo 4. see how the tires sit on a 8" rim, you judge

I ran mine with a big front bar and regular pressures this past weekend and the problem seemed to go away, the corners rounded off smooth like normal
IMO the OE or softer bars are allowing too much body roll, think I may have PAXd #1 (not that this means squat
