For better or worse (that’ll get some opinions) I have ‘re-tired’ once and went Pirelli Nero’s on the rear and original P-zero’s up front. Had a flat two weeks ago and had to use that bullshit system in the trunk but...observed two things. The front P zeros are not run-flat but did a great job of saving my MRR wheel even though it was completely deflated. The tire was shot but the goo and pump got me home. But I was close when it happened.

So, if you want to maintain original performance, go with P Zero. But you will pay for the privilege. : /
