Pirelli P Zero PZ4 220/40 R18 Alfa Romeo GT 3.2 14,000 miles March 3, 2020
These are the grippiest road tyres I've ever had. Amazing handling and braking distances both in dry and wet conditions. I just love how they hold the car on the road. Steering feedback is superb too. This amount of grip has its price though, it only lasted roughly 14k miles and I only have around 2.5-3 mm left so time for a new set. I also love that the outer rims protrude nicely and protect the alloy wheels well – on a 8 x 18" alloy, that is. The other minor negative is that aquaplaning performance is not exemplar, but I've learnt to go more careful around big puddles than usual. I don't believe this is a major weakness though, I am extremely happy with them and will keep buying the same set for this car.

Very good tyres, quiet and comfortable. Dry grip is very good as well road feedback. Best choice for that price!

Where this data comes from

Owner ratings are submitted through the review form on this site, naming the tyre, the size and the distance covered, and are checked by hand before publication. Test results come from independent published tyre tests indexed by size, and label values from the EU EPREL database.

About the TR Score

The Tyre Reviews Score rates each tyre out of 10 using independent test results and the full body of owner reviews, so you can check a car-specific ranking against the wider evidence.

Who does the testing

Every test published as a Tyre Reviews test is run by Jonathan Benson, who has been testing tyres independently since 2007.
