Michelin’s Pilot Sport 4S* (PS4S*) has been chosen by BMW as a 21-inch summer tire fitment for its new high-performance X3 M and X4 M models, and also as the sole fitment for the global press launch of these high-performance vehicles.

The new BMW X3 M and X4 M Competition models, which are fitted with the 21-inch light alloy wheels, will be equipped with MICHELIN PS4S* 255/40ZR21 102Y front and 265/40ZR21 105Y rear ultra-high-performance tires. These feature a number of Michelin technologies, including multi-compound tread patterns and an aramid-reinforced casing design, and the tires are star-marked (*) to signify that they are homologated BMW fitments.

The front tires feature Michelin’s tri-compound technology and the rears are bi-compound. Originally developed for endurance race tires, multi-compound technology uses different rubber compounds on different parts of the tread to fine tune the performance. As an example, the outer shoulder provides exceptional grip and wear resistance during cornering, intermediate ribs are optimised for steering and handling and the inner shoulder is designed to break through water and provide grip on wet roads.

When developing the tires, BMW’s engineers asked Michelin to concentrate on dry performance, high grip levels, good track endurance and good balance on wet surfaces, and all while maintaining the BMW M signature sporting feel at the steering wheel. The fact that the front and rear tire sizes are similar meant Michelin had to engineer the different characteristics with only the tread pattern and the compounds to ensure the design brief was met.

The combination of these technologies means the Michelin PS4S* achieves a unique balance between grip, comfort, safety and driving enjoyment that meets BMW M’s exacting standards and makes it suitable for everyday road use.

Whilst developing the tires, Michelin’s engineers focused on simultaneously improving performance in all of the different areas required, while still maintaining the others. The driver of the BMW X3 M and X4 M equipped with Michelin PS4S* tires can enjoy the experience, knowing that the tires deliver maximum safety and long life even in extreme conditions of use.
