Default Run flat?
My car has Michelin Pilot sport All season tires, sidewall has 4 ZP, is this a run flat tire? ZP I assume is zero pressure.


TIA, Frank

ZP is Michelin abbreviation for Zero Pressure so yes it is a Run Flat. Corvette engineering team made an outstanding decision to start moving supply of corvette OEM tires to Michelin from Goodyear starting in 2009 with the new C6 ZR1.

If you have a puncture, runflats allow you to stop when you want instead of when you must.
Driving very far on a flat can make the tire un-repairable, I consider 20 miles to be the normal limit for driving flat if you want to repair.

Which i consider to be a bargain.

~$500 to replace a tire is much preferable to possible damage from a tow.

There is no comparison between Goodyear RunCraps and Michelin ZP.
