The 2026 fleet buyer's guide to the low-profile metric successor to 11R24.5 — load ratings, SmartWay verification, modern 24.5-wheel fitment, and the Hanksugi drive and trailer lineup.
285/75R24.5 is the low-profile metric replacement for the imperial-standard 11R24.5 commercial truck tire size, and it is the tire that lets fleets running 24.5-inch wheels capture the same fuel-economy and rolling-resistance benefits that 295/75R22.5 delivered to 22.5-inch wheel operations. If you run modern Class 8 tractors spec'd for 24.5 wheels or you manage high-floor trailer fleets where deck height matters, 285/75R24.5 is almost certainly the right replacement tire. This page is the complete 2026 fleet buyer's guide — we explain exactly what 285/75R24.5 means, the two Hanksugi models available in this size, the load and ply specifications fleet managers need, SmartWay compliance status, current direct-to-fleet pricing, and how 285/75R24.5 stacks up against 11R24.5 and 295/75R22.5. Every Hanksugi 285/75R24.5 tire ships with factory warranty, DDP container delivery, and full-container pricing that beats national chain replacement pricing by 15-25%.
Reading the metric size code top-to-bottom: 285 is the section width in millimeters (approximately 11.2 inches sidewall-to-sidewall). 75 is the aspect ratio — the sidewall is 75% of the section width, or about 214 mm (8.4 inches). R indicates radial construction. 24.5 is the rim diameter in inches. The overall diameter works out to approximately 41.8 inches, sitting between 11R22.5 (41.5 in) and 11R24.5 (43.5 in). That shorter sidewall versus 11R24.5 is the entire point — lower sidewall flex, lower rolling resistance, better fuel economy, at the cost of about one inch of ground clearance.
For fleets converting their 24.5-inch-wheel trucks from 11R24.5 to 285/75R24.5, the fuel economy gain is consistently measured at 2-3% at highway cruise speed. On a long-haul tractor running 125,000 miles per year at $5.20/gallon diesel and 6.5 MPG average, that 2% gain is approximately $2,000 per truck per year. Multiplied across a 30-truck legacy 24.5-wheel fleet, that is $60,000 annual fuel savings — before any tire purchase savings from switching to direct-to-fleet pricing.
Hanksugi offers 285/75R24.5 in two premium models — a drive-axle fuel tire and a long-haul trailer tire. Both are SmartWay-verified and engineered for modern Class 8 over-the-road service.

Fleet managers comparing low-profile 24.5 options to 11R24.5 and to the 22.5 low-profile standard need this matrix:
| Metric | 285/75R24.5 | 11R24.5 | 295/75R22.5 |

| Sidewall Height | ~8.4 in | ~10.1 in | ~8.7 in |
| Load Index (typical) | 144/141L | 149/146L | 146/143L |
| Fuel Economy (relative) | Baseline | −2% | +1% |

If you are running modern Class 8 tractors spec'd for 24.5 wheels (moving van fleets, certain reefer trailer pools, legacy OTR carriers), 285/75R24.5 is the right fuel-economy upgrade path. If you are considering a wheel-and-tire refresh program, converting to 22.5-inch wheels and 295/75R22.5 is the larger opportunity — but the capex hit on new wheels has to pencil against the fuel savings.
Hanksugi prices 285/75R24.5 direct-to-fleet with DDP delivery to your yard. Full-container pricing (~266 tires) consistently beats retail chains by 15-25% while delivering SmartWay-verified rolling resistance.
Request Your 285/75R24.5 QuoteBoth Hanksugi 285/75R24.5 models (HS68 drive, HS66 trailer) are listed on the EPA's SmartWay Verified Tire Technologies list. This qualifies your fleet for SmartWay Transport Partnership status — a common prerequisite for large shipper and 3PL contracts — and supports compliance with the California Air Resources Board Phase 2 Greenhouse Gas Regulation, which penalizes non-verified sleeper-cab and trailer operation in California with fines up to $1,000 per tire per day.
SmartWay-verified 285/75R24.5 on drive and trailer positions delivers consistent 2.5-3% fuel economy improvement at highway cruise speed versus non-verified equivalents. On a tractor-trailer running 125,000 miles per year at $5.20/gallon diesel, that is roughly $2,000-$2,400 per truck per year in fuel savings alone. The mathematics is the same story we tell on every size landing page — SmartWay verification has a clear, repeatable, bankable economic return.
