Michelin’s Pro 4 SC increases the grip and longevity of the excellent but fragile Pro 3 to create a light, lovely feeling, top performance tyre that handles well and is also resistant to wear.
The carcass of the Pro 4 SC is the same as that of the Pro 3, so low weight is retained, but it gets a more durable centre compound. Michelin claim a 30-50 percent wear increase, and we’re already well past the point of Pro 3 death without any baldness or excessive cut/puncture issues.
It rolls well too, and a new pointed profile drops you into corners faster and more confidently for an infectiously aggressive feel whatever the weather.
Fitted to a Powertap rear wheel on a turbo trainer, the average wattage needed to sustain 20mph was 141 watts.
It’s definitely not a wise choice for roller/turbo trainer use though, as the extra heat softens the compound too much and leaves big dollops of tread on the rollers very quickly.
