Legendary tire manufacturer Pirelli knows a thing or two about performance where the rubber meets the road. From Formula One and World Rally Championships and FIM Superbike to YOUR bike! Enter Pirelli's P Zero Velo road bike tires. Offered in three variations, this is the Velo 4S, a harsh weather tire with outstanding wet grip and puncture protection. A slightly thicker rubber layer than the Velo, and a tread designed to shed water from your path, the 4S gives you maximum control when the weather gets rough. Wet or dry this tire performs.
