Disclosure: Pedal Brief may earn a commission if you buy through links on this page, at no extra cost to you. This version has no affiliate links. Nothing here was tested by us. Every tire, width and pressure below comes from the tire brand, the rim brand, or the standard, and each is linked. Full disclosures.

Who it's for: road riders on hookless (TSS) wheels who need a replacement tire and would rather not guess.

A hookless rim needs a tire approved for it. The approvals live on separate brand pages, in different formats, with different footnotes. This page puts them in one place.

Checked 24 September 2026. Brands update these lists. If your tire is not here, it may still be approved. Check the brand page linked in each section.

The short version

Hookless basics, as the sources state them

What "hookless" means. The official ETRTO name for a hookless tubeless rim is TSS, Tubeless Straight Side. (Schwalbe) Per Continental, a hookless rim holds the tire only by the bead and friction against the flange, with no hook to lock it in. Continental adds that hookless setups "seem to be more sensitive to deviations in system tolerances." (Continental)

Maximum pressure by tire width. Schwalbe publishes these maximums for its TLE/TLR tires on hookless rims, "in accordance with the ETRTO" (Schwalbe):

Nominal tire width Max pressure on hookless
18-24 mm 5.5 bar
25-29 mm 5 bar
30-34 mm 4.5 bar
35-39 mm 4 bar
40-44 mm 3.5 bar
45-54 mm 3 bar
55-64 mm 2.5 bar

The same figures appear, in kPa, in the ISO table of straight-side rim pressures that Bicycling reproduces. (Bicycling) Bicycling's article text gives 43.5 psi for 40mm tires, but its table puts that figure (300 kPa) at 45 to 54mm. We use the table.

Zipp's system limit. Zipp says its TSS wheel and tire systems "should never be inflated to more than 5 bar (72 psi)." Zipp TSS rims are also not compatible with tires that need a minimum pressure above 5 bar. If a pressure guide gives you more than 72 psi, Zipp's advice is to choose a wider tire. (Zipp)

Rim width matters too. Continental gives each hookless-approved size a maximum inner rim width. Its own example: if the tire brand allows 23 mm for a 28-622 tire and the rim brand allows 25 mm, you follow 23 mm. (Continental)

Minimum tire width by rim width. The 2023 ISO and ETRTO update ties the narrowest allowed tire to the rim's internal width. We could not read the standard itself, which is sold, not published. We use two reports of it and, at each rim width, take the stricter figure. TOUR summarises the 2023 ETRTO update as 25 mm tires up to 21 mm internal, 28 mm for 22 to 24 mm and 29 mm for 25 mm. Bicycling reproduces the ISO "Table 7, Recommended rim widths", which gives 25 mm for 21 to 22 mm rims, 28 mm for 23 mm and 29 mm for 24 to 25 mm, with narrower tires allowed below 21 mm. Neither is verified against the ETRTO or ISO text. (TOUR, Bicycling)

Internal rim width (hookless) Minimum nominal tire width (stricter source) Source
Up to 21 mm 25 mm TOUR (Table 7 allows narrower below 21 mm)
22 to 23 mm 28 mm TOUR (Table 7: 25 mm at 22 mm, 28 mm at 23 mm)
24 mm 29 mm ISO Table 7 via Bicycling (TOUR: 28 mm)
25 mm 29 mm TOUR and ISO Table 7; ENVE states it too

The only disagreement is at 24 mm. TOUR puts it at 28 mm and Table 7 at 29 mm. Table 7 may not be specific to hookless rims, but on a safety question we use the stricter number. For rims wider than 25 mm, Table 7 lists 35 mm tires as the narrowest for 26 to 27 mm rims and 47 mm for 28 to 30 mm. We found no hookless-specific source that confirms those, so follow your wheel maker.

Two rim makers back part of this. ENVE says "ISO/ETRTO recommends a 29c minimum tire size with 25mm internal rim width." (ENVE) Zipp says the 2023 update means a tire "cannot deviate more than 2mm from its marked size," so most 28 mm tires fall outside the recommendation on its 25 mm rims. Zipp still lists some 28 mm tires it has validated with the tire maker. (Zipp) Your rim maker's chart is the one to follow.

Heat raises pressure. Continental puts the rise at roughly 0.17 bar (2.5 psi) for every 10°C. It suggests not inflating to the hookless maximum if you ride through big temperature swings. (Continental) Pumping to 72 psi in a cool garage before a hot ride is how you go over the limit without touching the pump.

Tubes. Zipp says tubes are fine in TSS-compatible tires, but the tire itself must still be TSS-compatible. (Zipp) Schwalbe says the same for its TLE/TLR tires. (Schwalbe) A tube does not make a non-approved tire safe on a hookless rim.

Approved by the tire brand

These are the tire makers' own statements. Widths are nominal (what is printed on the tire).

Continental

Continental publishes the hookless maximum pressure and maximum inner rim width for each size. (Continental hookless table)

Tire Size Max pressure hookless Max inner rim width
Grand Prix 5000 S TR 25-622 5.0 bar / 72 psi 21 mm
28-622 5.0 bar / 72 psi 23 mm
30-622 4.5 bar / 65 psi 25 mm
32-622 4.5 bar / 65 psi 25 mm
30-584 (650b) 4.5 bar / 65 psi 25 mm
32-584 (650b) 4.5 bar / 65 psi 25 mm
Grand Prix 5000 AS TR 25-622 5.0 bar / 72 psi 21 mm
28-622 5.0 bar / 72 psi 23 mm
32-622 4.5 bar / 65 psi 25 mm
35-622 4.0 bar / 58 psi 25 mm
Grand Prix 5000 TT TR 25-622 5.0 bar / 72 psi 21 mm
28-622 5.0 bar / 72 psi 23 mm
Aero 111 26-622 5.0 bar / 72 psi 22 mm
29-622 5.0 bar / 72 psi 25 mm
Grand Prix TR 25-622 5.0 bar / 72 psi 21 mm
28-622 5.0 bar / 72 psi 23 mm
30-622 4.5 bar / 65 psi 25 mm
32-622 4.5 bar / 65 psi 25 mm

The new Aero 111 32-622 (announced August 2026) is described as "hookless rim compatible." (Continental press release) It was not yet in Continental's hookless table when we checked, so we have no official rim-width limit for it. Check the packaging.

Worth noting: this is the GP5000 S TR, not the older GP5000 TL. Giant lists the older GP5000 TL as having failed its hookless test. (Giant)

Pirelli

The P ZERO Race TLR product page says compatibility is "subject to specified pressure limitation (sizes 26-622 are not compatible with hookless rims)." (Pirelli) Pirelli's catalogue lists 28-622, 30-622, 32-622, 35-622 and 40-622 as the sizes above 26-622. The widths are Pirelli's; the pressure limit is yours to apply from the table above.

One conflict to know about: Giant's page lists P ZERO Race TLR in 28 and 30 mm among tires that failed Giant's test protocol. (Giant) Giant's page does not say which production version it tested. If you ride Giant or CADEX hookless wheels, Giant's list wins for your wheels.

Vittoria

Vittoria marks hookless compatibility per size on each product page. As of our check:

"WR" is Vittoria's Wide Rim Optimized size. Vittoria describes it as a "29 mm tire section width on 25 mm internal rim width." (Vittoria) Vittoria's pages do not list per-size hookless pressures, so use the table above and the rim maker's limit.

Hutchinson

Hutchinson says that from its 2025 range, all road tubeless-ready tires in 700x28 mm and wider from the Blackbird, Blackbird Race, Blackbird All Season and Challenger lines work on hooked and hookless rims, "as long as the maximum indicated pressures are strictly adhered to." Its gravel and MTB tires are also compatible within their pressure limits. (Hutchinson)

Hutchinson also names what is not hookless compatible: Fusion 5 Performance, Fusion 5 All Season, Intensive, Sector, Equinox, Epsilon, Nitro, Quartz and Speed'n'Stop, unless the rim maker authorizes them. (Hutchinson)

Schwalbe

Schwalbe does not list model by model. It says its TLR and TLE tires from model year 2020 onward are "generally compatible," and that only TLE/TLR tires may go on hookless rims. The rim maker's approved tires and minimum widths still apply. (Schwalbe) Look for TLE or TLR on the sidewall and check the model year.

Approved by the rim brand: Giant and CADEX

Rim makers publish their own lists, and they do not always match the tire makers.

Giant says a tubeless tire marked hookless compatible by its maker, with a stated maximum of 72.5 psi (5 bar) or lower, can be used on Giant hookless wheels without being on any list. Tires with a stated maximum above 5 bar need to have passed Giant's test. (Giant)

Non-Giant/CADEX road tires that passed, per Giant (Giant):

Tire Widths passed
Continental GP5000 S TR 25, 28, 30 mm (25 mm only on SLR 1 and 2 42 wheels, per Giant's note)
Goodyear Eagle F1 R 28 mm
Hutchinson Challenger TL 28, 32 mm
IRC Formula Pro HL TL RBCC 25, 28, 30 mm
IRC Formula Pro HL TL X-Guard 25, 28, 30 mm
IRC Formula Pro HL TLR S-Light 25, 28, 30 mm
Maxxis High Road TR 25, 28 mm
Maxxis High Road SL TR 25 mm
Michelin Power Cup TL Ready 25, 28 mm
Michelin Power Road Tubeless 25, 28, 32 mm
Panaracer Agilest TLR 28, 30 mm
Pirelli Cinturato Velo 28, 32, 35 mm (only versions marked 72 psi / 5 bar max on the sidewall)
Schwalbe One TLE 25, 30 mm
Schwalbe Pro One TLE 25, 28, 32 mm
Veloflex Corsa Evo TLR 25 mm
Veloflex Corsa Race TLR 25 mm
Vittoria Corsa N.EXT 28, 30, 32, 34 mm
Vittoria Corsa Pro 28, 30, 32 mm

Giant also lists tires that failed its protocol on Giant hookless wheels: Continental GP5000 TL (25, 28, 30, 32), Pirelli Cinturato (24, 26), Pirelli P ZERO Race TLR SL (24, 26, 28), Pirelli P ZERO Race TLR (24, 26, 28, 30), Specialized Roubaix Pro 2Bliss (31), Veloflex Corsa Evo TLR (28), Vittoria Corsa TLR (25, 28) and Vittoria Rubino Pro TLR (25, 28, 30). (Giant)

The GP5000 case shows why the exact model name matters: the S TR passed and the older TL failed.

Zipp wheels

Zipp says any tire marked TSS-compatible on the sidewall or packaging works on Zipp TSS wheels. Zipp keeps a checkmark chart of tires, including some "dual-validated" by both Zipp and the tire maker. (Zipp) The chart did not load in a form we could read reliably, so we have not reproduced it here. Check it directly if you ride Zipp.

Safety margins: what TOUR found

German magazine TOUR looked into hookless safety in 2024, including lab tests. The points below are TOUR's reporting. (TOUR)

TOUR also notes that rim makers' compatibility lists sometimes contradict the current ETRTO recommendation. Its advice: if in doubt, choose the safer combination, meaning wider tires and less pressure.

How to check your own setup

  1. Find your wheel's internal rim width and its maximum pressure. Both are usually on the rim decal or in the manual.
  2. Confirm the exact tire model and size is hookless approved by the tire brand. Look for "TSS" or "hookless" on the packaging or sidewall.
  3. If your wheel brand publishes a list (Giant, Zipp and others do), check it too.
  4. Take the lowest maximum pressure from the tire, the rim and the ETRTO table. Take the lowest maximum rim width.
  5. If a pressure calculator tells you to go above that, go wider on the tire, not higher on the pump. Our road tire pressure guide shows where 28, 30 and 32mm tires hit the hookless ceiling by rider weight.
  6. Check your pump gauge against a separate gauge. At a 72.5 psi ceiling, a few psi of gauge error matters.
