"What Our Gearhead® Experts Are Saying: ""I’ve been running the Vector R Z30 SW on my Zipp 303s for long, mixed-condition rides. It’s super smooth, reliable in the wet, and the 30mm casing gives just the right balance of comfort and precision. Honestly, it’s become my go-to for big days and unpredictable weather.""Endurance rides are unpredictable. That’s why we ride tires that aren’t just fast, but versatile, and the Goodyear Vector R Z30 SW delivers exactly that. Designed to match the performance profile of the Zipp 303 SW wheelset, this 30mm-wide road tire is built to balance speed, grip, and confidence in all conditions, from alpine descents to chip-seal farm roads. The supple 120 TPI casing and short-ply construction offer road-smoothing flexibility, while the Dynamic:UHP rubber compound enhances rolling efficiency and grip in both wet and dry terrain. With Goodyear’s Tubeless Complete system, the Vector R Z30 SW installs easily and maintains air better than traditional tubeless designs. Whether we’re chasing a fast century or heading out into the unknown, this tire keeps us rolling smooth and safe."
