Below is the most recent road tire compatibility information for Zipp wheels with an ETRTO/ISO Tubeless Straight Side (TSS) rim-tire interface.

All Zipp TSS rims meet specifications as outlined by ISO and ETRTO. Per ISO standards, tire fitment with ISO compliant rims is the responsibility of the tire manufacturer. Any TSS-compatible tire as denoted on the tire sidewall or packaging is compatible with Zipp TSS wheels. Tires denoted below by a green checkmark represent compatibility as reported by the manufacturers for their respective tires. This list is not exhaustive of all TSS compatible tires and is provided as a convenience to help guide your tire purchases. Zipp TSS rims should only be used with TSS-compatible tires. Do not use tires that are not TSS-approved. Tubes may be used with TSS-compatible tires. If you have further questions about tire fitment, we recommend you reference the tire manufacturer’s website or contact them directly.

Dual-validated tire compatibility;
Zipp works with tire manufacturers to cooperatively test and approve TSS-compatible tires outside of ISO tire and rim size recommendations. These tires are denoted by two green checkmarks and have been dual-validated on Zipp wheels both by Zipp and by the tire manufacturer. Zipp testing protocol includes an overinflation test to 150% of the system max pressure rating held for one hour. Do not exceed the system max pressure rating as indicated on your wheels.

ISO tire compatibility for 303 XPLR wheels;
Zipp limits the tire size compatibility on 303 XPLR wheels to tires between 40-60mm. Within this range, ISO tire and rim size guidelines allow any TSS-compatible tire sized from 58x622 up to 60x622 (29”x2.3”-2.35”).

  • Important Notice: Zipp TSS rims are NOT compatible with tires that require a minimum pressure higher than 5 bar (72 psi). Please follow the tire manufacturer's recommendations for the minimum pressure that is printed on your tire. Zipp TSS wheel and tire systems should never be inflated to more than 5 bar (72 psi). Please use the SRAM Tire Pressure Guide to help discover your optimum tire pressure. 
  • TSS-compatible gravel tires are safe to use on Zipp TSS rims within the ISO max system pressure ratings for a given tire size. In case of a doubt, please consult the tire manufacturer. 
  • Zipp TSS wheels are designed for TSS-compatible tires only. Inner tubes are ok, but the tire must be designed for TSS-compatibility for safe retention. 
  • Zipp TSS wheels meet the existing industry standards for the dimensions that control tire retention. Tire manufacturers determine tire compatibility with TSS-compliant wheels.
  • Zipp actively collaborates with tire manufacturers within ISO and ETRTO committees to develop clear international standards for TSS road tires. 
  • Tire brands have a right to declare which products are compatible or not with TSS rims. 
  • If you are interested in a tire that is not listed here, you should check with the tire manufacturer or reference their website to see if the tire is compatible with Zipp wheels. 
  • Zipp's tire pressure guide will help you determine your ideal air pressure. Choose a larger tire size if the recommended pressure for your setup is above 72psi / 5 bar.
