Pirelli P Zero XL FSL - 265/35R20 99Y - Summer Tire

A milestone in the development of the Pirelli range, P ZEROT has been chosen as original equipment for the most performance orientated and powerful models on the market. A reference point for the ultra high performance segment, it is characterised by an asymmetric tread pattern. Ideal for all top of the range sports and highpowered cars, it can also be considered for powerful midrange vehicles.'. It is a ultra high performance tyre, technologically the most advanced.A tyre designed for the most prestigious OE fitments on premium new models.Another milestone in a continuous story of succes.The new tread design offers superior handling and braking performance on both dry and wet surfaces.The new high grip coumpund with nanocomposites in the perfect solution for an enhanced driving stability and sensitive steering control.Three wide longitudinal grooves ensure an high aquaplaning resistance, while the sshaped sipesare deigned to reduce rolling noise.The external area with large, rigid blocks is the ideal support to exalt handling characteristics when driving on the limit.

The European Union has introduced the EU Tyre Label by Regulation (No. 1222/2009) identically and bindingly for all EU member states. It applies to passenger car tyres, light commercial vehicle tyres and heavy commercial vehicle tyres produced after 01.07.2012. With this regulation, the European Union is pursuing the goal of promoting economic and ecological efficiency in road traffic as well as increasing road safety on the one hand, and on the other hand, granting consumers more product transparency and at the same time serving as an active decisionmaking aid.

Already during the incorporation, experts criticise the fact that the EU Tyre Label unfortunately only shows a few product characteristics. Apart from rolling resistance, wet grip and rolling noise, which are the main focus of EU tyre labelling, tyres have much more important and safetyrelevant product characteristics, such as aquaplaning properties, driving stability, service life, braking properties on dry and wet roads, behaviour in wintry conditions, etc. Tyre manufacturers point out that test results from various institutions and journals remain an important information medium for the end consumer.

These tests usually focus on further safetyrelevant product characteristics besides the EU standard qualifications for tyre labelling, which are always important for the final customer. Car had 20" 245/35r20 runflats in front and 275/30r20 runflats (all MOE) for RWD w213 luxury saloon.The car came with these factory fitted MOE runflat tyres. I've Replaced these tyres and wheels at 10600km. Steering as a result is very precise in both wet and dry. Front 245/30s have sound deadening foam and overall tyre noise is quiet in the cabin (but just wee bit louder than the 18" PS4 tyres I replaced them with).

Ride comfort is 8/10 on highways due to air suspension. On chip seal, speed humps, potholed roads ride comfort is 5/10 there is very abrupt jarring transmitted to cabin due to tyre profile and rims. Wet grip in cold (5'C) and damp country highways was 7/10 at 110km/h speeds there was some slip noticeable. Dry grip was 8/10 most of the time but with occasional rear traction slips at highway speeds in curves. This combination of tyres and rims is quite poor for a luxury sedan and compliant rides.

I have used Pirelli P Zeros for about 15 yrs and they are a great tyre. I ordered a run flat tyre, only to find several months later it is not!.
