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.

With Goodyear’s Tubeless Complete system, the Vector R Z30 SW installs easily and maintains air better than traditional tubeless designs.
