Complete guide 2026 for fleets in Antigua and Barbuda: the imperial equivalent of 315/80R22.5. Technical specifications, 6 Hanksugi models for steer, drive and all-position, and direct fleet pricing for heavy trucks, urban and inter-island buses across the Caribbean.
The 12R22.5 is the inherited imperial standard for heavy trucks and buses across the Caribbean and wider Americas, and the direct equivalent of the modern metric size 315/80R22.5. If you operate a fleet of older trucks and buses in Antigua and Barbuda, it is very likely your vehicles are fitted with 22.5-inch rims specified for 12R22.5 tyres. This size remains the backbone of heavy-transport operations including port haulage at Saint John's and English Harbour, general freight, construction, distribution and bus services on routes connecting Saint John's, All Saints, Parham, Falmouth and the island's main roads. This page is the complete buyer's guide for 2026: what the 12R22.5 designation means, the 6 Hanksugi models available for Caribbean fleets, technical specifications, the relationship with the 315/80R22.5, direct fleet pricing, and how this size suits Antigua and Barbuda's tropical conditions and road network.
Breaking down the designation: 12 is the section width in inches, equivalent to approximately 305 mm from sidewall to sidewall. In the imperial nomenclature, width is expressed in inches rather than millimetres. R indicates radial construction with full steel belt package. 22.5 is the rim diameter in inches. Unlike metric sizes such as 315/80R22.5 which state the aspect ratio explicitly, the imperial designation 12R22.5 does not show this figure; a full-profile aspect ratio of approximately 100% is assumed, producing an exceptionally tall sidewall and an overall diameter of approximately 1,067 mm (42.0 inches). This tall sidewall is one of the reasons the size is so valued in vocational operations: it absorbs impacts, protects the casing and offers excellent resistance to damage on unpaved and deteriorated roads.
The 12R22.5 was the industry standard for heavy trucks and buses before metric nomenclature was widely adopted in the 1980s and 1990s. Whilst European markets and truck manufacturers transitioned rapidly to the metric designation 315/80R22.5, many Caribbean markets retained the 12R22.5 owing to the long service life of their vehicle platforms and the practicality of maintaining existing rim inventories. Today, the 12R22.5 and the 315/80R22.5 coexist across the region, with the imperial size dominating in fleets with older equipment and the metric size predominating in newer Volvo, Scania and Mercedes-Benz acquisitions.
The 12R22.5 and the 315/80R22.5 are the closest equivalents but are not identical. The 12R22.5 has a section width of 305 mm (12 inches), whilst the 315/80R22.5 is slightly wider at 315 mm. In practice, many Caribbean fleets fit both sizes on the same vehicles without significant operational issues, although manufacturers recommend adhering to the vehicle's original specification. The decision between one and the other generally depends on the fleet's existing rim inventory and local availability of each size. Hanksugi offers the same tread patterns in both sizes to facilitate the transition for fleets migrating from 12R22.5 to 315/80R22.5 or running both sizes simultaneously.
Hanksugi offers the 12R22.5 size in six models covering all wheel positions and work cycles required by Caribbean fleets. This is the widest range Hanksugi offers in a single size, reflecting the importance of the 12R22.5 in the regional market. Direct fleet pricing for full container orders starts at USD $340 per tyre.

If your fleet operates older vehicles with an established imperial rim inventory, the 12R22.5 is the most economically sensible option: it maintains compatibility without requiring investment in new rims. If you are purchasing new vehicles or renewing your rim inventory, transitioning to 315/80R22.5 offers greater load capacity due to its wider section. For applications where fuel efficiency takes priority over maximum load capacity, the 295/80R22.5 deserves consideration for its lower weight and rolling resistance. Hanksugi can supply all three sizes from the same container for fleets in transition running a mix of sizes.

Request a 12R22.5 QuoteThe 12R22.5 tyre is used across a variety of work cycles in Antigua and Barbuda, each with different performance expectations and cost per kilometre. The figures below reflect the experience of Caribbean fleets operating with Hanksugi tyres under tropical conditions, coastal salt air and on a mix of sealed and unsurfaced roads:
Retreading is an essential component of 12R22.5 tyre economy in the Caribbean. The retreading trade is well established in the region, allowing fleet operators to extend casing service life significantly. Hanksugi 12R22.5 casings are designed specifically to maximise casing retention and accept quality retreads, which reduces the total cost per kilometre by between 25% and 40% compared with using new tyres only.
The 12R22.5 size is fitted on a wide range of heavy trucks and buses operating across Antigua and Barbuda. The most common vehicles include:
The 12R22.5 is a size with strong demand across the Caribbean and the wider Americas, particularly in markets with older vehicle fleets. Hanksugi supplies directly to fleets across these markets:
The largest market in the Americas for 12R22.5 tyres. Brazil's enormous fleet of Mercedes-Benz, Volvo, Scania and Ford Cargo trucks consumes this size in massive volumes. The retreading trade is especially well established in Brazil, with a world-class network of retreaders.
Strong demand in mining, forestry transport and heavy-haulage fleets. Northern mining and southern forestry operations require highly durable 12R22.5 tyres. Earlier-generation Volvo and Scania trucks predominate in these segments.
A solid market for 12R22.5 on older heavy-truck platforms serving port haulage at Saint John's and English Harbour, construction across the island, and inter-island freight. The tall sidewall handles the island's mix of sealed trunk roads and rougher rural and site roads well.
Sustained demand in grain, livestock and mining transport. The extreme distances of Patagonia and the north-west require highly durable tyres with strong retreading capability. Mercedes-Benz and Scania dominate the Argentine heavy fleet.
Mining operations for copper and gold in both countries consume 12R22.5 tyres on legacy imperial-rim platforms. Inter-city passenger transport also generates consistent demand for this size.
Whilst Mexico primarily consumes North American sizes (11R22.5, 11R24.5), a segment of European-origin buses and trucks uses 12R22.5. In Guatemala, Honduras, Panama and Costa Rica, inter-city buses on legacy Mercedes-Benz and Volvo platforms maintain stable demand.
The 12R22.5 and the 315/80R22.5 are the closest equivalents in the imperial and metric systems respectively, but they are not identical. The 12R22.5 has a section width of 305 mm whilst the 315/80R22.5 measures 315 mm. In practice, many Caribbean fleets fit both sizes on the same vehicles. The 315/80R22.5 is the modern metric replacement with slightly higher load capacity, but the 12R22.5 remains the right option for fleets with established imperial rim inventories.
Three main reasons: first, many fleets operate older trucks and buses that were originally specified with imperial tyres, and replacing all rims across a fleet is a significant investment. Second, the distribution and retreading network for 12R22.5 tyres is well established in the region, making this size readily available. Third, the 12R22.5 delivers excellent performance under Caribbean operating conditions, with tall sidewalls that absorb impacts on deteriorated roads.
Mercedes-Benz Axor and Atego trucks, Volvo N/NL Series, Scania P/T Series, Ford Cargo, Iveco Stralis and Trakker, and a wide range of urban and regional buses with Marcopolo, Comil, Busscar and other bodywork. This size is also used on tippers, concrete mixers, tankers and construction vehicles on platforms with imperial-size specification.
Hanksugi offers 6 models in 12R22.5, the widest range in a single size: HS24+ (drive deep tread), HS26+ (premium steer), HS28+ (premium regional drive), HS54 (all-position mixed service), HS58 (drive severe service) and HS64 (all-position with stone ejection). This range covers all positions and work cycles that Caribbean fleets require.
