Based on a recent tire test in the German press the Goodyear Eagle F1 (Z06 tire, right?) and the PZero Hero (599GTB etc.) offer very similar track performance as the Michelin Sport Cup tire...


So why would anyone use anything else than run-flat tires, if there's no performance gain?

I'm totally lost why any performance-oriented car (like GT3 RS) would use anything less than best tire available.





I don't quite understand your question, I guess...

My point is: the Goodyear Eagle F1 (Z06) or Pirelli PZero Hero (599GTB) are very close to cup tires like Michelin PS Cup in terms of performance. Thus changing from either tire to cup tires should not improve lap times significantly.
