Complete 2026 guide for fleets: specifications, 5 Hanksugi models, direct pricing and a size comparison for this North American-standard tyre used on Class 8 tractors, raised-floor trailers and vocational vehicles in Antigua and Barbuda and across the Caribbean.
The 11R24.5 is the inherited North American standard for Class 8 heavy trucks fitted with 24.5-inch rims. If you operate tippers, concrete mixers, long-haul tractors with sleeper cabs, raised-floor trailers for removals, refrigerated trailers, vehicle carriers, or any tandem-axle vocational vehicle that requires additional ground clearance and maximum load capacity on a 24.5-inch rim, the 11R24.5 is the size you need. In Antigua and Barbuda, this size is used on freight vehicles serving Saint John's port, construction projects in areas such as English Harbour and Jolly Harbour, and general haulage across the island. This page is the complete buyer's guide for 2026: what the size numbers mean, the 5 Hanksugi models available, load and pressure specifications, direct fleet pricing, mileage expectations, and how the 11R24.5 compares with the 11R22.5 and the 285/75R24.5.
Breaking down the tyre size designation: 11 is the nominal section width in inches, equivalent to approximately 279 mm from sidewall to sidewall. Unlike metric sizes that express width in millimetres, the 11R24.5 uses the inherited imperial system where the leading number indicates inches. R indicates radial construction with steel belts. 24.5 is the rim diameter in inches. The aspect ratio is not stated explicitly in the imperial designation and is assumed to be approximately 90%, which produces a tall sidewall and an overall diameter of roughly 1,105 mm (43.5 inches). This extra size compared with tyres on 22.5-inch rims provides greater ground clearance, higher load capacity, and the visual proportions that many classic truck operators prefer.
The 11R24.5 has been the industry standard for North American heavy trucks since the 1960s. Although the trend since the 1990s has been conversion to 22.5-inch rims for fuel efficiency and cost reduction, the 11R24.5 maintains a solid presence in tippers, mixers, classic inherited tractors, and specialised raised-floor trailers. For operations in Antigua and Barbuda that run North American-specification equipment from Freightliner, Kenworth or Peterbilt, the 11R24.5 remains the daily-use size maintained in local inventory.

Although the North American industry has largely migrated to 22.5-inch rims for fuel efficiency, the 11R24.5 holds a firm position in several specific segments. Tippers and concrete mixers value the greater ground clearance provided by the 24.5-inch rim. Raised-floor trailers for removals and vehicle transport require the additional height to accommodate bulky loads. Fleets with large existing inventories of 24.5-inch rims find it more economical to stay with the size than to replace an entire wheel park. In Antigua and Barbuda, operators running North American-specification Freightliner, Kenworth and Peterbilt equipment will find the 11R24.5 a readily sourced size kept in stock by tyre suppliers.
The 11R24.5 is fitted to a wide range of Class 8 heavy vehicles with a North American heritage. Classic long-haul tractors such as the Freightliner Classic XL, Peterbilt 379 and 389, Kenworth W900 and C500, and Western Star 4900 were originally specified with this size. In vocational applications, tippers from Mack Granite, Kenworth T880 and Peterbilt 567 use it for its higher load capacity and ground clearance. Raised-floor trailers for removals, vehicle carriers and raised-floor refrigerated trailers also depend on the 11R24.5 to achieve the platform height required.
In the drive position, the 11R24.5 is fitted to the drive axles of the tractor, where the Hanksugi HS88 with its hexagonal block design delivers superior traction in both dry and wet conditions. For fleets prioritising fuel economy, the HS68 with its closed shoulder and lower rolling resistance is the ideal choice. In the trailer position, the HS86 and HS66 offer even tread wear and maximum casing durability. For vocational operations in construction, port haulage or mixed-service duty, the HS84 with its reinforced sidewall and cut-resistant compound is the right choice.
In Antigua and Barbuda, the 11R24.5 is used by operators hauling freight between Saint John's port, construction sites at English Harbour, Jolly Harbour and across the island, and general distribution routes passing through All Saints, Parham and Willikies. The tropical heat and coastal salt air demand tyres with robust construction, and the mix of well-maintained main roads and rougher unpaved tracks on worksites favours the HS84's reinforced sidewall for vocational duty. Across the wider Caribbean, the Dominican Republic, Jamaica and other islands running North American-specification trucks also use this size for construction, distribution and port haulage.
Fleet managers evaluating options on 24.5-inch rims frequently compare the 11R24.5 with the 11R22.5 (smaller rim) and the 285/75R24.5 (modern metric equivalent). Here is the complete comparison:
| Parameter | 11R24.5 | 11R22.5 | 285/75R24.5 |
|---|---|---|---|
| Rim Diameter | 24.5 in | 22.5 in | 24.5 in |
| Overall Diameter | 1,105 mm | 1,054 mm | 1,062 mm |
| Load Index | 149/146L | 146/143L | 144/141L |
| Maximum Single Load | 3,250 kg | 3,000 kg | 2,800 kg |
| Ground Clearance | Greater (+25 mm vs 22.5) | Standard | Lower than 11R24.5 |
| Fuel Economy | Standard | Better (~2%) | Better (~2%) |
| Primary Application | Vocational, raised-floor trailer, classic | General use, long-haul | Efficient long-distance |
If your trucks require the greater ground clearance and load capacity of a 24.5-inch rim, the 11R24.5 is the right choice. If your priority is fuel economy and you are already running modern platforms, the 285/75R24.5 or conversion to a 22.5-inch rim is worth evaluating. If your fleet has a large existing inventory of 24.5-inch rims and the cost of conversion is not justified, staying with the 11R24.5 is the economically rational decision.

Request a Quote for 11R24.5The cost per kilometre of 11R24.5 tyres depends primarily on application and duty cycle. Realistic expectations for each segment are as follows:
In all applications, correct inflation is the single most critical factor in maximising mileage. A 11R24.5 tyre operating at 10% below recommended pressure loses approximately 15% of its service life. Monitoring tyre pressure with a TPMS system is an investment that pays for itself within the first tyre rotation cycle.
The 11R24.5 is specified as original equipment and replacement fitment on the following types of heavy vehicles, with particular relevance for Caribbean and North American-specification fleets:

Guatemala, Honduras, El Salvador and Panama operate North American-specification equipment on heavy-haul routes. Fleets running Freightliner and Kenworth trucks require 11R24.5 for long-haul and vocational operations.
Mining operations using imported North American equipment demand the 11R24.5 for tipper and heavy machinery fleets. Lower volume than 315/80R22.5 but steady demand in these specific segments.
The 11R24.5 is used on Class 8 heavy trucks of North American heritage: Freightliner Cascadia and Classic, Kenworth T680 and W900, Peterbilt 579 and 389, Mack Granite and Anthem, International LT and HX, and Western Star 4900. It is also fitted to raised-floor trailers for removals, vehicle carriers, raised-floor refrigerated trailers, vocational tippers and concrete mixers. In Antigua and Barbuda it is commonly found on port freight and construction vehicles serving Saint John's and surrounding areas.
The primary difference is rim diameter: 24.5 versus 22.5 inches. The 11R24.5 has a larger overall diameter (1,105 mm vs 1,054 mm), providing roughly 25 mm of additional ground clearance per axle. It also carries a slightly higher load index (149/146L vs 146/143L). The 11R22.5 is more fuel-efficient and represents the modern industry trend, but the 11R24.5 remains preferred for tippers, raised-floor trailers and fleets with existing 24.5-inch rim inventories.
Mileage from 11R24.5 tyres varies by position and application. On long-haul drive duty with correct inflation and rotation, premium Hanksugi tyres return between 130,000 and 240,000 km depending on the severity of the duty cycle. Trailer tyres typically achieve higher mileage (225,000–320,000 km). A retread can significantly extend casing life, bringing the total value to more than 400,000 km in dedicated highway applications.
Hanksugi 11R24.5 tyres are direct fleet-priced between USD $290 and $430 per tyre depending on the model (HS88 premium drive, HS86 trailer, HS68 high-efficiency drive, HS66 value trailer, HS84 vocational). Container-volume pricing (~250 tyres) offers savings of 15–25% versus local dealer pricing. DDP delivery is available for Antigua and Barbuda, the Caribbean and the United States.
