Product description & features

Michelin have created the Pilot Sport 4 S with an ultra-reactive tread pattern design, which adapts continuously to the road, to deliver an optimised surface footprint.

The Pilot Sport 4S features Michelin's 'Dynamic Response' technology – made from a hybrid belt of aramid and nylon, providing motorists with an optimum handling performance.

Exceptional dry grip and improved wet braking have been achieved thanks to the use of a Bi-Compound technology.

The tyre also features a novel hybrid elastomer for dry grip and a new mix of compound with specific “functional elastomers” and silica for wet grip and braking.

Pilot Sport 4 S For Road & Track

Michelin have developed the PS4s tyres for both road and occasional track usage.

Through the use of Michelin's Pilot Sport Technology, the Pilot Sport 4S provides motorists with reliable braking performances throughout the lifespan of the tyre.

Whilst the Bi-Compound Technology delivers a continued high performance in wet and dry conditions.

Steering Precision with the Michelin Pilot Sport 4S

The Michelin PS4s' ultra-reactive tread pattern includes the use of hybrid architecture for precise and responsive steering.

The multi-compound technology adapts to various conditions to ensure that you remain in control of your vehicle should the weather change from dry to wet, or vice versa, when you are out on the road.

Michelin PS4S Aestheic Design

As with all of Michelin's tyres, the Pilot Sport 4 S boasts a premium design.

The PS4s tyre's sidewall features a dark velvet effect, for increased visual and tacticle appeal, and the symmetric tread design pattern gives the tyre a dynamic appearance. 

The tyre comes with a deep rim protector that offers your car with some light wheel damage protection. 

Michelin Pilot Sport 4s tyres are available in 18 inch, 19 inch, 20 inch, 21 inch, 22 inch and 23 inch rim tyre sizes.

Very poor on ice; caused a slide which resulted in an insurance claim and a month off the road. Do not use these tyres in ice conditions if possible.
