Pirelli 255/40 R19 100Y P Zero PZ4 I* 2024

The Pirelli P Zero PZ4 255/40 R19 100Y is a summer ultra-high-performance tyre developed for premium cars and SUVs. This exact configuration is XL reinforced and carries a 100 load index, corresponding to 800 kg maximum load per tyre, together with a Y speed rating for speeds up to 300 km/h. The supplied 2024 designation identifies the manufacturing year. The I* marking is a BMW i-specific original-equipment homologation, making the exact marking important when matching the tyre to the vehicle.

About Pirelli P Zero PZ4 255/40 R19 100Y I*

The Pirelli P Zero PZ4 255/40 R19 100Y I* is part of the fourth-generation P Zero family, developed by Pirelli with vehicle manufacturers for high-performance applications. Pirelli lists this exact size as an XL 100Y specification with BMW I* homologation. The PZ4 is a summer tyre focused on dry and wet road performance, high-speed braking and traction, while its construction also considers ride comfort and rolling resistance. For Dwbtyres customers looking to buy car tyres in UAE, the BMW I* marking should be checked carefully because the same 255/40 R19 size exists in several different PZ4 versions.

Dry-road handling and steering response

The 255 mm width and 40-series profile give this P Zero PZ4 a performance-oriented contact shape with relatively firm sidewall support. The XL construction is suited to vehicles requiring the higher 100 load index. Pirelli describes the PZ4 as an ultra-high-performance summer tyre designed to maximise high-end vehicle performance, including handling during sporty driving and braking and traction at high speed. This makes the configuration more appropriate for drivers prioritising steering precision and cornering control than for those seeking a soft touring feel.

Wet-road grip and braking

Pirelli's PZ4 uses a customised inner tread design with a high-silica compound intended to support wet performance, traction and riding comfort. The manufacturer also uses a high-pitch sequence in the inner tread and a differentiated outer tread design. Pirelli's catalogue identifies the BMW I* version separately from the generic and other BMW-starred PZ4 versions, so wet-grip and rolling-resistance classifications should not be transferred from another homologation.

Tread design and high-speed stability

The PZ4 employs an asymmetric tread with customised inner and outer zones. Pirelli describes the inner section as being optimised for wet safety, traction and comfort, while the outer section uses a lower-pitch sequence and siping to help reduce noise and rolling resistance. Tailored tread compounds are used to balance rolling resistance, wet performance and mileage. The design is therefore clearly road-focused and performance-oriented rather than intended for winter or all-season use.

BMW i application and everyday driving

The I* marking is particularly relevant to this product because Pirelli identifies it as a BMW i homologated PZ4 in 255/40 R19 100Y XL. This makes the tyre relevant to an approved BMW i fitment where this exact specification is required. The 40-series profile remains relatively low, so ride response over sharp road imperfections can be firmer than with a higher-profile touring tyre. Buyers should follow the vehicle manufacturer's approved tyre specification rather than treating the size alone as sufficient for fitment.

Who should choose this Pirelli?

This Pirelli P Zero PZ4 is best suited to a buyer whose vehicle specifically calls for the 255/40 R19 100Y XL BMW I* specification and who wants a summer tyre with performance-focused handling and high-speed capability. It is less suitable for someone looking specifically for winter traction, maximum sidewall cushioning or an all-season tyre. The supplied product should not be treated as RunFlat because Pirelli separately lists a RunFlat PZ4 in this size.

For customers comparing Pirelli Tyres, the complete 100Y XL and BMW I* markings are more important than the size alone. Dwbtyres buyers should verify the sidewall markings against the vehicle documentation before purchase, particularly where the vehicle requires an OE-specific tyre.
