The Michelin Pilot Sport 4S is an ultra high-performance tyre, something that is exemplified by its status as an OE supplier to BMW. In June 2019, BMW chose the Michelin Pilot Sport 4S as a 21-inch summer tyre fitment for its new high-performance X3 M and X4 M models. According to company, 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 at the Nurburgring in Germany, and Miramas and Ladoux test tracks in France.
