Are the PZero so bad in these conditions
The PZero's are terrible tires and I am impatient to get rid of the original factory set on my Turbo S (991.1). I thought that I was prejuduiced because of my previous bad experience with every hi-end Pirelli set that I've ever had but then a few of my 911 friends told me that they even got rid of the factory Pirelli's immediately.
So yeah, these are bad tires and the only reason we get them is probably some cost-saving by Porsche. On the other hand, I've never had Michelin's that I didn't like...winter or summer.
I couldn't agree less, sorry to say that. The new PZero N1 for the 991.2 Turbo S is one of the best road tires available on the market (look at how it performs in various reviews) but it may not be that good in the wet at lower temperatures. Also, when it is wet, you never really know if there is something else...like a watery mix of dirt, dissolved leaves or even oil or coolant liquid. This is why I am always careful in the wet.
Also, I can assure you that Porsche using the PZero has not as much to do with cost as you think. Pirelli is very flexible when it comes to adapting tires to manufacturer needs and this is what makes Pirelli a good partner for manufacturers.
I also noticed that the PZero is very tire pressure sensitive and works always best with the lowest recommended tire pressure. Unfortunately this is also the so called "comfort" tire pressure which limits speeds to under 270 kph.
