24.5×8.25 Tubeless Steel Wheel

Where the 24.5×8.25 wheel fits

The 24.5 rim diameter is a regional system rather than a global one. It is the standard tractor and trailer fitment in the United States and Canada, common in Mexico wherever fleets run North American-specification equipment, and it appears elsewhere on imported or second-hand North American trucks and trailers. A 22.5 tyre does not mount on a 24.5 rim, so a fleet that runs 24.5 is committed to 24.5 wheels for the life of the vehicle. That is why a dependable 24.5x8.25 tubeless steel wheel supplier belongs on file even for distributors whose main volume is 22.5.

The 8.25-inch rim width is the everyday width of the 24.5 system: it carries the 11R24.5 tyre used in dual fitment on drive and trailer axles, and the same wheel serves the steer position on many chassis. We supply it from the 15°DC tubeless catalogue, which covers rim diameters from 16.5 to 24.5 inches; the complete list, including the 24.5×11.75, 24.5×13 and 24.5×15 sizes, is on the technical catalogue page.

Catalogue configurations

Three configurations are listed for the 24.5×8.25 size; the values below are reproduced from the catalogue as printed.

Tyre: 24.5-inch tubeless truck tyres (e.g. 11R24.5), within the rim widths approved by the tyre manufacturer. — = weight not listed in the catalogue; finished weight, valve-hole position and finish are stated per configuration on the quotation.

Reading the three configurations

The three rows answer three different hub systems; the wrong one will not bolt on.

• PCD 335 · centre bore 281 · 10×26 H1 — the 10-stud hub-piloted pattern used on ISO-pattern chassis (European and many Asian-built trucks). With a 14 mm disc and 7 mm rim it is the heaviest section of the three.
• PCD 285.75 · centre bore 220 · 10×26 H1 — the North American hub-piloted pattern: the wheel is centred by the hub bore and clamped by flange nuts. 12 mm disc, 6 mm rim.
• PCD 285.75 · centre bore 221.5 · 10×32 JSR22 — the ball-seat (stud-piloted) version of the same bolt circle: 32 mm holes with spherical seats take ball-seat nuts, and the nuts locate the wheel rather than the bore. This is the older North American system, still common on trailers.

Offset is 154 mm on the PCD 335 wheel and 156 mm on both PCD 285.75 wheels — the deep dish that dual fitment calls for. When replacing an existing wheel, match PCD, bolt form, centre bore and offset together rather than PCD alone; the PCD and bolt pattern chart shows how to measure each on a wheel in hand.

Load rating and weight (market reference)

The catalogue does not print a load rating or a finished weight for the 24.5×8.25 rows, so this page does not quote one. As a market reference only, North American-market 24.5×8.25 steel wheels are commonly rated in the 7,400 lb (≈3,360 kg) class per wheel — not a figure for these catalogue models. The rating and weight of the configuration you order are stated on the quotation. The load rating guide explains how to size from your axle loads and why disc thickness (12 or 14 mm here) and finished weight are the numbers to ask every supplier for.

Frequently asked questions

Which tyres fit a 24.5×8.25 tubeless steel wheel?

24.5-inch tubeless truck tyres — most commonly 11R24.5 — in the sizes the tyre manufacturer approves for an 8.25-inch rim width. 22.5-inch tyres do not fit: 22.5 and 24.5 are separate rim-diameter systems and are not interchangeable.

What is the difference between the H1 hub-piloted and JSR22 ball-seat versions?

The hub-piloted wheel centres on the hub through its bore (220 mm on the PCD 285.75 version, 281 mm on the PCD 335 version) and is clamped by flange nuts through 26 mm holes. The ball-seat wheel has 32 mm holes with spherical seats and is located by ball-seat nuts on the studs. The two are not interchangeable — match the wheel to the hubs and nuts already on the vehicle.

Is the 24.5×8.25 wheel available with PCD 335?

Yes. The catalogue lists a 10×26 H1 hub-piloted configuration with PCD 335, centre bore 281 mm, offset 154 mm, 7 mm rim and 14 mm disc, alongside the two PCD 285.75 configurations.

Do you supply the load rating and weight for this wheel?

Both are stated per configuration on the quotation; the catalogue itself does not print them for the 24.5×8.25 rows, so this page does not quote a figure. North American-market wheels of this size are commonly rated in the 7,400 lb (about 3,360 kg) class — a market reference only. Size the wheel from your axle loads using the load rating guide.
