The Primacy HP ZP (Zero Pressure technology) is Michelin's Grand Touring Summer run flat tire developed to provide longer tread life and lasting performance throughout the tire's life, as well as better braking, steering control and handling on wet roads. The Primacy HP ZP also offers temporary mobility (up to 50 miles at 55 mph) in the event of air loss for current BMW 3-Series sedans, coupes, cabriolets and wagons and Z4 roadsters, as well as MINI Cooper and Cooper S hatchbacks and convertibles featuring Original Equipment self-supporting run-flat tires. While Primacy HP ZP tires are designed to offer reliable traction in dry and wet conditions, they are not intended to be driven in near-freezing temperatures, through snow or on ice.
Primacy HP ZP tires benefit from Michelin design innovations known as A.S.M. (Architecture, Sculpture and Materials) that reflect Michelin's ability to focus simultaneously on three fundamental factors that determine a tire's capabilities. Using their A.S.M. design method, Michelin can develop tires that combine an architecture that deforms more easily to optimize contact with the road, a tread design sculpture that remains rigid so more of the footprint contributes to performance, and unique tread compound materials precisely blended by Michelin's mixing technology.
Primacy HP ZP tires use a new generation Michelin tread compound molded into an asymmetric tread design that features large, linked shoulder blocks, notched intermediate ribs and a solid center rib to combine responsive handling and high-speed stability with traction and even treadwear. The Primacy HP ZP tire's structure includes twin steel belts reinforced by size-optimized BAZ Technology (spiral-wrapped Polyamide Banded At Zero degrees to tire rotation) to enhance ride quality while providing high-speed durability. Sidewall reinforcement using low hysteresis rubber provides self-supporting strength at zero-pressure, helps combat sidewall damage, and maintains cool temperatures to allow longer zero-pressure driving while a special bead design helps tires stay securely seated on conventional rims.
The Tire Labeling Ordinance specifies the information requirements on fuel efficiency, wet grip and external rolling noise from tires. In addition, reference is made to the winter properties of the product.
The EU 1222/2009 regulation that has been in force since November 1st, 2012 has been revised and will be replaced by regulation EU 2020/740 from May 1st, 2021; From this point on, new requirements apply. The rating classes for fuel efficiency, wet grip and exterior noise have been changed and the layout of the EU label has been adjusted. The manufacturer's product data sheets stored in the EU database can be downloaded via a QR code integrated into the label. Information on snow grip and ice grip is also newly included for tires that meet these criteria.
The following tires are exempt from the regulation: - tires that are designed exclusively for installation on vehicles that were first registered before October 1, 1990 - retreaded tires (until a corresponding extension of EU VO 2020/740 has taken place) - professional off - Road tires - Racing tires - Tires with additional devices to improve traction, eg studded tires - T-type emergency tires - Tires with a permissible speed below 80 km/h - Tires for rims with a nominal diameter ≤ 254 mm or ≥ 635 mm
The criteria and evaluation classes at a glance
fuel efficiency
The fuel consumption depends on the rolling resistance of the tyres, the vehicle itself, the driving conditions and the driving style of the driver. The measured rolling resistance (rolling resistance coefficient) of the tire is divided into classes A (highest efficiency) to E (lowest efficiency).
If a vehicle is completely equipped with class A tires, a consumption reduction of up to 7.5%* is possible compared to class E tyres. In the case of commercial vehicles, it can even be higher. (Source: European Commission Impact Assessment * when measured according to the test methods set out in Regulation (EU) 2020/740)
Please note: Fuel consumption depends to a large extent on your own driving style and can be significantly reduced by driving in an environmentally friendly manner. Tire pressure should be checked regularly to improve fuel efficiency.
wet grip
Wet grip is divided into classes A (shortest braking distance) - E (longest braking distance).
If a car is equipped with class A tires, compared to class E tires, a braking distance of up to 18 m can be reduced when braking from 80 km/h (on a road surface with average grip).* *Source: wdk Economic Association of the German Rubber Industry eV
Please note: Traffic safety depends to a large extent on your own driving style. The stopping distances must always be observed. Tire pressure should be checked regularly to improve wet grip.
External rolling noise
The noise emitted by a tire affects the overall volume of the vehicle and affects not only your own driving comfort, but also the noise pollution of the environment. In the EU tire label, the external rolling noise is divided into 3 classes from A (lowest rolling noise) - C (highest rolling noise), measured in decibels (dB) and compared with the European noise emission limit values for external tire rolling noise.
A The pictogram with the classification "A" indicates that the tire's external rolling noise is more than 3 dB below the EU limit value in force until 2016. B The "B" classification means that the tyre's external rolling noise is up to 3 dB below or equal to the EU limit value in force until 2016. C The classification "C" indicates that the specified limit value is exceeded.

25.08.2014fromGerard A fantastic summer/wet tyre, the best I've had to date
10.03.2014fromChris Thomas Good tyre from a very good supplier
12.04.2012fromGoran Comfortable in the beginning but ended up being very noisy due to uneven wear of outer thread blocks.
