About Pirelli P ZERO™ (PZ4) 205/40R18 86W XL Run Flat *

The P ZERO™ (PZ4) is Pirelli's fourth-generation P ZERO ultra-high-performance summer tyre. It was developed using Pirelli's motorsport experience and through collaboration with leading vehicle manufacturers, with the aim of delivering high levels of handling, braking and traction for performance-oriented vehicles. 

Ultra-High-Performance Summer Design

The P ZERO™ (PZ4) is designed specifically for high-end cars and SUVs requiring responsive handling and high-speed road performance. Its construction and tread compound are optimized for dry and wet-road driving. 

Wet-Road Performance

Pirelli uses a high-silica tread compound in the inner tread area to support wet-road safety and traction. The tread design is intended to provide strong wet performance while maintaining driving comfort. 

The P ZERO™ (PZ4) is engineered for sporty driving, with a focus on handling, braking and traction at high speeds. Its customized tread design and performance-oriented compound help provide the road response expected from a UHP summer tyre.

This specification features Pirelli Run Flat technology. In the event of a loss of tyre pressure, the reinforced Run Flat construction is designed to help maintain vehicle control and allow the driver to continue to a suitable location rather than stopping immediately. Pirelli states that, under the applicable Run Flat conditions, the tyre can be driven for up to 80 km at a maximum speed of 80 km/h after a puncture. 

XL Load Version

The 205/40R18 specification is an XL, or Extra Load, version. It carries a load index of 86, corresponding to a maximum rated load of 530 kg per tyre under the applicable conditions. Pirelli confirms the XL designation for this exact fitment. 

W Speed Rating

The W speed category corresponds to a maximum rated speed of 270 km/h. This rating is appropriate for compatible performance vehicles, subject to the vehicle manufacturer's tyre requirements and applicable speed limits. 

Original Equipment Star Marking

The star (*) marking identifies this specification as an original-equipment tyre developed for a specific vehicle manufacturer's requirements. The exact Pirelli listing confirms the * OE marking for the 205/40R18 86W XL Run Flat specification. 

Low Noise and Rolling Resistance Design

Pirelli's customized outer tread design uses an optimized pitch sequence and siping arrangement to reduce external noise and rolling resistance. The tread compound is also developed to balance rolling resistance, wet performance and mileage. European Tyre Label

For the listed European-market specification, Pirelli reports a B fuel-efficiency class, B wet-grip class and A external rolling-noise class with an external noise value of 68 dB. 

Summer Application

The P ZERO™ (PZ4) Run Flat 205/40R18 is a summer tyre and is not designed for severe ice and snow conditions. Pirelli specifically identifies this specification as not intended for severe ice and snow.

2024 Production

The requested product is specified as a 2024 tyre. The exact manufacturing week of an individual tyre should be verified from the DOT/date code printed on its sidewall, because the model and size specification alone do not establish the production week.

Who Should Consider This Tyre?

Pirelli P ZERO™ (PZ4) 205/40R18 86W XL Run Flat * is suited to compatible performance cars and SUVs requiring this exact original-equipment specification. It is particularly relevant to drivers seeking UHP summer handling, strong wet and dry performance, a high W speed rating and Run Flat capability.
