Finished up my second set of Pzero scrubs. I used 305/680-18 up front and 325/680-18 in the rear. -3.6 up front, -2.6 rear with neutral toe.

As with the first set, they were good for two days, then fell to crap on day 3. The difference this time, I continued to push them hard on the third day. By the end of the third 20 minute session on that third day, I had started to rip them up (pictures attached). When this setup gives way, it's the fronts that suffer most, and the car was pushing badly.

With the first set, I backed off of them on the third day, so none of the carnage you see here.

I started on 24lbs of pressure. Tested them hot after the first run and dropped them to 29-30. Went with that the rest of the day.

Overall, given the price I'm paying, I have no complaints. Two good days and a third suspect day. Going to 660 for the fronts next time, but only out of caution; the 680s up front had no obvious rubbing and no "ice mode" issues.
