Can I run this gravel tire on hookless rims?

Every answer comes from the tire brand's own page, the ETRTO pressure table as Schwalbe publishes it, or the ETRTO 2024 rim table, as quoted in our hookless gravel tire guide (brand pages checked 12 Oct 2026, US pages where they exist). Not tested by us. The max pressure is a ceiling, not a recommendation: pick your riding pressure with the tire pressure calculator, which caps hookless setups at the same limits.

How the answer works

• Approved: "Yes" only when the tire brand says so, for that tire or size, or for all its tires of that type. "Brand doesn't say" means the brand pages we checked have no hookless statement. Zipp: "Do not use tires that are not TSS-approved."
• Max pressure: the lowest of the ETRTO hookless limit for the tire width, the brand's own figure where it gives one, and your rim's limit if you enter it. When tire, rim and standard differ, follow the lowest figure (Continental, Hutchinson and ENVE say so). Psi is our conversion, rounded.
• Rim: the tire widths the ETRTO 2024 table lists for your inner rim width (Schwalbe's printing, checked against Continental's for these rims), plus the tire brand's own rim width where it gives one. Your rim maker's chart and minimum tire width come first.
• Heat adds pressure: Continental: "With every 10°C | 18°F rise in temperature, the inflation pressure increases by roughly 0.17 bar | 2.5 PSI!"
• Sizes: for Continental, Pirelli, Vittoria and the Maxxis Rambler, only the sizes in the guide are listed. Vittoria's list is the sizes marked hookless approved on its US store; check Vittoria's size table for others.

Hookless max pressure by tire width

Schwalbe: "Maximum air pressure recommendations for Schwalbe TLE/TLR tires on hookless or straight side rims are as follows in accordance with the ETRTO:" (the table above). A tire's printed maximum can be higher: Schwalbe's US page lists the G-One R Pro 40-622 at 65 PSI / 4.5 bar.

Where the brands disagree

• Continental: its knowledge page lists 5.0 bar (73 psi) hookless for Terra Speed and Trail at 35 and 40 mm and 4.5 bar (65 psi) at 45 mm and Hardpack. The US product pages give those as the hooked figures and list 4.0 / 3.5 / 3.0 bar for hookless, which matches the ETRTO table. The tool uses the product page figure, the lower one. Check the packaging too. No Terra tire is on Zipp's gravel lists.
• Pirelli: the Gravel S cites 5 bar / 73 psi; the ETRTO table sets 3.5 bar at 40 to 44 mm and 3 bar at 45 to 54 mm. The lower, width-based figure applies.
• Hutchinson: the Touareg page has a hookless tag but also lists tube-type wire-bead versions. Schwalbe, Giant and CADEX tie hookless to tubeless tires.
• Panaracer: "Tubeless Compatible up to 60 PSI on most models". 60 psi is above the ETRTO hookless limit at 35 mm and wider (58 psi at 35 to 39 mm), so the lower figure applies. Hookless is listed for 700 x 30C and wider; 700x26C and 700x28C need a tube.
• Rene Herse: a 2020 Rene Herse Journal post recommends a 60 psi (4.1 bar) maximum for tubeless tires (marked TC), above the ETRTO limit at 35 mm and wider. Rene Herse says Enve and Zipp rims "are fine to use with all Rene Herse tires", but Zipp's 303 XPLR S list names three 44 mm Endurance tires.
• Maxxis: no hookless statement in the 2026 catalog, which lists the Rambler 700x40 and 45 for 17 to 27 mm inner rims; Zipp lists Rambler, Ravager and Reaver 40 and 45 and Receptor 40 as dual-tested on the 32 mm 303 XPLR S.
• Specialized, WTB: no statement on the pages checked. Zipp lists WTB Raddler, Resolute, Riddler, Venture and Vulpine on the 303 XPLR S.

What the rim makers require

• Zipp: "Any TSS-compatible tire as denoted on the tire sidewall or packaging is compatible with Zipp TSS wheels." The 303 XPLR S (32 mm inner) is stricter: for 40 to 57 mm tires, only tires on Zipp's list. Zipp says ISO recommends 58 to 83 mm tires for that rim, the same range the ETRTO 2024 table lists for 31 to 35 mm rims, so the tool flags narrower tires there.
• ENVE: tire must be TSS hookless compatible and pressure must never exceed the rim's rating. Minimum tires: G23 28 mm, G27 42 mm, AG25 36 mm, AG28 45 mm. ENVE gives the AG28 with a 45 mm tire as "40 psi/3.10 bar" in one place and "45 psi/3.10 bar" in another.
• Giant and CADEX: Giant allows tires rated 72.5 psi (5 bar) or lower that the brand calls tubeless and hookless compatible. CADEX: "Every hookless compatible tire clearly indicates a maximum (MAX) pressure of 72.5 psi (5 bar)." Many gravel tires show lower hookless maximums.
• Hunt: the 40 Carbon Gravel Race (25 mm inner) is rated for 29 to 60 mm tires. "Only use tires suitable for hookless (TSS) rims. If unsure, please contact the tire manufacturer."
• Not checked: DT Swiss, Roval, Bontrager, Reserve, Challenge, Tufo, Teravail and Goodyear pages.
