After three years of development, the Michelin Primacy 4 tyre provides exceptionally high levels of performance on wet roads. What really sets the Primacy 4 apart from its competitors is its long-term performance, from the first use as a brand new tyre, right down to the last mile when the tyre reaches its legal tread limit. The tyre continues to respond exceptionally under braking even when worn. Compared to its direct competitors, the new Michelin Primacy 4 brakes on average 2.5m shorter in the wet when new and 5.1m shorter when worn.* That means that you and your family will be safe when the tyre is new and safe when it is worn!
