Pirelli P ZERO™ (PZ4) Reviews

After 22000km tyres delaminated forcing me to purchase another brand as replacement.  Absolutely a waste of time

Lovely square wear right across the tyre face. Smaller sipes on shoulders still present (often get worn out at this distance). Holds pressure well. Could do with a slightly larger rim saver.

These Pirelli PZero PZ4 (*) RFTs were the OE fitment to my car. I’m a bit ambivalent about them, but I’m not sure if it’s the fact they’re run-flats that’s the main contributor. They’re good all-rounders, fairly quiet and steer really well, but I rate them less highly than the Michelin PS4 tyres on my Jaguar for rear grip in both wet and dry. The car never seems quite to settle, there’s an underlying jitteriness to the ride on anything other than billiard-table smooth roads that can become a bit wearing. My car has adaptive dampers, but that characteristic is apparent whether in Comfort or Sport modes. I suspect it’s the harder sidewalls and high pressures mandated for run-flats (39 psi) that are the main contributors. Big bump absorption is pretty good though. Non Run-flats may be a little more forgiving, and when I replace these I’ll probably go that route (and buy a tyre inflation kit as my car has no spare).

Excellent grip especially in the wet

They have a nice looking edge which i reckon that provides a measure of protection against curb rash. Traction not as good as expected - tendency to slip under hard accel on damp roads.

One tyre developed bulges in sidewall while vehicle stored in workshop before car was really ever driven. Pirelli Australia and Italy refused to reply and retailer claim it must have hit a pot hole without even removing the tyre to inspect. Removed all 4 and replaced with Khumo PS91's which are excellent. Will never ever purchase any Pirelli branded product again.

These tyres were on the car as factory fitted and have lasted a mix of continuous and casual driving (highway and rural roads) over the last three and a half years. Very quiet to start with, but road noise increased as they wore down. They are now down to the stops with 26,500 km on them. I consider this a pretty good run for a high performance tyre. Noted there are a few comments about these tyres hydroplaning. Experienced it in very heavy rain on a poorly draining highway (110km/h), with water cutting across both lanes. Price wise they appear to be very cost competitive. Currently looking to make a change to compare. Slim change I may go with the same again.

A very good all rounder with strong performance. Starting to get a tad noisy on rougher surfaces.

Car came factory fitted with these R20 RFTs. The dry grip is excellent and the steering is very precise with these tires on the car. Wet grip is very good too, although I have been cautious as other commenters have stated that the aquaplaning on these tires is not good. Braking is very good so far. The tire sidewalls protruding out has protected my rims a few times when parking at the kerb. If you like sporty dynamics this tyre and wheel combo is excellent. My complaints are that despite my car cabin being superbly quiet, the 20" Runflats transmit road noise into the cabin. The Merc's air suspension makes you glide across, however the tires get quite a knock from potholes and bumps which can feel harsh in the cabin as well. For a floaty executive sedan, the car would benefit more from 18" wheels with larger tire profile and non-RFTs.

Great tyres. Except worn to nothing in 16,000km's. Purchased Feb'20, have to be replaced Dec '20. Only checked review sites to see if others have same experience, previous tyres (unknown) did 50,000km exactly the same driving style on the same car. Either something is seriously wrong with this set of 4, or these Pirelli PZ4's are too soft for relatively benign (ie: Australian) driving on outskirts of Sydney in a Volvo station wagon.
