305/30 21 Tire Review Highlights

Continental SportContact 7 rated 94% while driving a Porsche TAYCAN
Driving on a combination of roads for 200 spirited miles
Replaced the OEM Pirelli PZ4 NF0. I had doubts for the longest of time, since the Taycan is really heavy and the OEM Pirelli is designed for this car with stiffer sidewall to handle this extra weight. Boy was I wrong. The SC7 is really spectacular with better steering feel, better braking, noticably better traction and a bit more progressive. It also understeers less than the Pirelli. The only thing I miss from the Pirelli is that super quick steering response, but the Continental is not that far off. Comfort is also better. Pretty much everything is better except for steering response. Impressive tire.

Pirelli P Zero PZ4 rated 70% while driving a Porsche TAYCAN
Driving on a combination of roads for 1500 spirited miles
OEM tire for the Taycan GTS. Quite a ride I had with these tires. The Taycan is nothing to play with. It is a 600hp, 2,3 tone, elecric beast with instant torque. This NF0 version of the PZ4 can really hold its own ground against this car. Dry performance is excellent, you can pretty much do whatever you want to do. Traction is great, balance is great, steering is delightful even when you push really hard. Really love it. My only complaint is that it is a bit clumsy when it begins to slide. You get used to it through, it is not something really scary. Wet perfomance is equally good. A click below dry performance but very good overall. Comfort is kind of average, same goes for noise, it is actually a bit noisy. I really liked this tire, until...I decided to try dry drifting. The tire was literally torn to pieces after 4-5 minutes (not consecutive). Half the tire was gone after this very short session. It really cannot handle it and I am quite surprised that it is approved by Porsche for OEM. Did the same thing with different tire setup and it was just fine (considering the weight of the car). I bought a second pair right after and tried wet drifting this time. Same thing! Much less this time, but a few tire blocks were once again detached. I now have a weird love and hate relatiosnhip with this tire. Will not buy them again, even though I admire what they can do.
