If you’ve invested in Zipp 303 S wheels, one of the most important questions to answer is: what tires are Zipp 303 S approved? Because these wheels use a modern hookless, tubeless-first rim design, not every tire will work. Choosing the right approved tire ensures both safety and performance. Let’s break down what you need to know.
Why Tire Approval Matters
The Zipp 303 S features a 23mm internal hookless rim. This design saves weight and improves aerodynamics, but it requires tires that are specifically rated for hookless rims. Using non-approved tires can result in dangerous blow-offs at pressure. That’s why Zipp and major tire brands publish official compatibility lists.
Approved Tire Standards
For a tire to be Zipp 303 S approved, it must meet these requirements:
- Tubeless-ready (TLR): The tire must be designed for tubeless setups, even if you plan to run tubes inside.
- Hookless compatibility: The tire must be labeled as safe for hookless rims.
- Width: Zipp recommends a minimum of 28mm for road use, with support for up to 40mm for gravel.
Examples of Approved Tires
While the full list is available on Zipp’s official compatibility chart, many popular options are approved, including:
- Road: Continental GP5000 S TR, Schwalbe Pro One TLE, Vittoria Corsa N.EXT TLR.
- All-road: Pirelli Cinturato Velo TLR, Goodyear Eagle F1 Supersport TLR.
- Gravel: WTB Riddler TCS, Maxxis Rambler TLR, Panaracer GravelKing SS+ TLR.
Pressure Limits
Even with approved tires, the Zipp 303 S has a maximum inflation pressure of 72.5 psi (5 bar). Wider tires should be run at lower pressures for safety, comfort, and rolling efficiency.
Final Thoughts
So, what tires are Zipp 303 S approved? Any tubeless-ready tire specifically rated for hookless rims in widths from 28mm to 40mm. Popular road, all-road, and gravel tires from brands like Continental, Schwalbe, Vittoria, and WTB all have approved models. Always check Zipp’s official tire compatibility list before mounting new tires to maximize safety and performance.
