those tires are the new Pilot Sport Cup 2. can't wait to try them!

 

Just listened to that interview, very interesting as the plot thickens. Lieb basically said he did not go all out (safety concerns) and that there is still a quicker lap in the 918. He mentioned about the understeer that forum members noticed and that all the nannies were turned off for the record lap. I also inferred that Porsche is still continuing to develop the car till the last possible minute ;0)
