Michelin Chosen by BMW for New X3M and X4 M

BMW has chosen the Michelin Pilot Sport 4S (PS4S) tyres as a 21-inch summer tyre fitment for its new high-performance X3 M and X4 M models.

Tyrepress.com reports that the new BMW X3 M and X4 M Competition models, which are fitted with 21-inch light alloy wheels, will be equipped with Michelin PS4S 255/40ZR21 102Y front and 265/40ZR21 105Y rear ultra-high performance tyres.

Michelin has a long and successful relationship with BMW M and has designed tyres for many of the manufacturer’s previous models. These tyres are the result of almost three years of co-development between BMW M and Michelin.

During this development phase around 800 prototype tyres and 1,400 pre-production tyres were produced and tested and the Nürburgring in Germany, and Miramas and Ladoux test tracks in France.


The front tyres feature Michelin’s tri-compound technology and the rears are bi-compound. Originally developed for endurance race tyres, multi-compound technology uses different rubber compounds on different parts of the tread to fine-tune the performance.

When developing the tyres, BMW M’s engineers reportedly asked Michelin to concentrate on dry performance, high grip levels, good track endurance and good balance on wet surfaces, while maintaining the BMW M signature sporting feel at the steering wheel.

The fact that the front and rear tyre 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.

Michelin high-performance tyres have been, or are currently fitted to BMW’s M2, M3, M4, M5, M6, X5 M and X6 M models.
