The 2026 fleet buyer's guide to the Class 8 heavy-haul standard — load index, spec sheet, pricing, and the Hanksugi vocational lineup for tankers, lowboys, construction, refuse, and severe-duty fleets across the Americas.
315/80R22.5 is the heavy-haul standard for Class 8 vocational and severe-duty trucking. If you operate cement mixers, dump trucks, refuse collection trucks, tanker trucks hauling fuel or food-grade liquids, logging tractors, lowboy heavy-equipment haulers, or any tractor running a 14,600 lb or 20,000 lb front axle spec, 315/80R22.5 is almost certainly the size on your steer, drive, or all-position fitment. This is not a long-haul fuel economy tire — it is a severe-duty workhorse designed to haul the heaviest legal loads, survive curb impacts and construction-site cuts, and accept multiple retread caps before retirement. This page is the complete 2026 buyer's guide — what the numbers mean, which Hanksugi vocational models fit the size, the load and pressure specs vocational fleet managers actually need, pricing, duty-cycle expectations, and how 315/80R22.5 compares to 11R22.5 and 385/65R22.5 for severe-service applications.
Reading the sidewall: 315 is the section width in millimeters — approximately 12.4 inches, making this one of the widest standard 22.5-rim commercial tires available. 80 is the aspect ratio, meaning the sidewall height is 80% of the section width, or about 252 mm (9.9 inches). That tall sidewall is what gives 315/80R22.5 its characteristic vocational-tire look and is the reason the tire can absorb curb hits, construction-site debris, and on/off-road punishment without casing failure. R indicates radial construction. 22.5 is the rim diameter in inches. A 315/80R22.5 mounts on a 22.5 × 9.00 inch wheel, has an overall diameter of approximately 42.3 inches, and weighs 150-170 lbs per tire depending on ply rating and tread depth — heavy for a reason.
The 315/80R22.5 size was standardized in the late 1980s as the European heavy-haul metric replacement for 12R22.5 and 13R22.5 imperial sizes. It has since become the worldwide standard for cement, tanker, construction, refuse, logging, and heavy-haul truck tires because it delivers the highest load capacity (156/150K load index, 8,270 lbs single) available in any standard 22.5-inch rim size. The combination of high load capacity, tall sidewall impact resistance, and excellent retreadability is exactly what vocational fleets require.
Hanksugi offers 315/80R22.5 in three premium vocational models, each engineered for a specific severe-duty application. Direct-to-fleet container pricing starts at $380 per tire and scales with volume. Container loads are typically ~200 tires due to the larger physical size.
Heavy-haul drive tire with aggressive lug tread, cut and chip resistant compound, and reinforced sidewall. Designed for cement, construction, dump truck, and logging tractor drive axle duty.
View HS58 →All-position vocational tire with closed-shoulder design for mixed on/off-road service. Excellent for tanker, refuse, and municipal fleet applications requiring curb resistance and long casing life.
View HS54 →Mixed-service drive tire with optimized tread depth and compound for fleets running 60/40 highway-to-jobsite duty cycles. Better highway wear than HS58 with acceptable off-road durability.
View HS56 →Every Hanksugi 315/80R22.5 tire is built to the same core dimensional and load specification, with tread pattern and compound varying by model. Here is the specification sheet vocational fleet managers actually need:
| Specification | 315/80R22.5 |
|---|---|
| Section Width | 315 mm (12.4 in) |
| Aspect Ratio | 80% (252 mm sidewall) |
| Construction | Radial, all-steel belt |
| Rim Diameter | 22.5 in |
| Overall Diameter | ~42.3 in (1,076 mm) |
| Recommended Rim | 22.5 × 9.00 in |
| Ply Rating | 20 (Load Range L) |
| Load Index | 156/150K |
| Max Load Single | 8,270 lbs (3,750 kg) |
| Max Load Dual | 7,385 lbs (3,350 kg) |
| Max Cold Pressure | 130 psi (900 kPa) |
| Speed Rating | K (68 mph / 110 km/h) |

Vocational fleet managers comparing heavy-haul sizes typically evaluate 315/80R22.5 against 11R22.5 (legacy imperial standard) and 385/65R22.5 (super single wide-base). The short answer: 315/80R22.5 delivers the highest load capacity in dual-wheel configuration, and is the right choice for applications that require maximum axle load on standard dual-wheel axles. Here is the comparison matrix:
| Metric | 315/80R22.5 | 11R22.5 | 385/65R22.5 |
|---|---|---|---|
| Overall Diameter | 42.3 in | 41.5 in | 42.2 in |
| Load Index (single) | 156K | 146L | 164J |
| Max Load Single | 8,270 lbs | 6,610 lbs | 10,200 lbs |
| Dual-Wheel Axle Max | 14,770 lbs | 12,010 lbs | n/a (single only) |
| Sidewall Height | 252 mm (tall) | ~225 mm | 250 mm |
| Curb Impact Resistance | Excellent | Good | Good |
| Recommended Duty | Heavy vocational, tanker, lowboy | Legacy vocational | Weight-reduction super single |
If your trucks run standard dual-wheel drive and trailer axles and need the maximum legal load, 315/80R22.5 is the right answer. If your trucks run single super-wide trailer axles for weight reduction, 385/65R22.5 delivers higher single-tire capacity. If your trucks are legacy vocational fleet on 11R22.5 that have not exhausted their casing inventory yet, staying on 11R22.5 is reasonable — but new OE vocational tractors increasingly spec 315/80R22.5 as the factory-standard heavy-haul size.

Request Your 315/80R22.5 QuoteHeavy-haul tires do not follow the same cost-per-mile math as long-haul tires. Vocational fleets measure tire economics in yards-of-cement, loads-to-landfill, hours-of-service, or on-the-jobsite days rather than annual miles. Here are the realistic expectations for 315/80R22.5 across major vocational duty cycles:
In all cases, 315/80R22.5 delivers superior sidewall impact resistance versus long-haul low-profile sizes, which is the single most important factor for vocational tire survival. Fleet managers who try to save money by using long-haul 295/75R22.5 on vocational routes invariably see premature sidewall casualties and higher total cost per service day.
315/80R22.5 is spec'd as OE and replacement on virtually every modern heavy-haul Class 8 vocational tractor sold in North America. Common fitments include:

315/80R22.5 is the heavy-haul standard for Class 8 vocational and severe-duty tractors including cement mixers, dump trucks, lowboy tractors, tanker trucks (fuel, water, food-grade liquid), refuse and waste trucks, logging tractors, and heavy-equipment haulers. It is also used as a steer tire on tractors running 14,600 lb or 20,000 lb front axles where standard 11R22.5 or 255/70R22.5 do not have enough load capacity.
The standard Hanksugi 315/80R22.5 heavy-haul truck tire carries a load index of 156/150K, delivering 8,270 lbs single and 7,385 lbs dual at 130 psi cold. This is the highest load capacity available in any 22.5-inch rim size and makes 315/80R22.5 the correct specification for tankers, lowboys, and construction tractors hauling loads that exceed what 11R22.5 or 295/75R22.5 are rated for.
315/80R22.5 is primarily a heavy-haul and vocational tire, not a long-haul tire. Its tall sidewall (252 mm aspect ratio 80%) and aggressive shoulder construction deliver sidewall impact resistance and maximum load capacity — but with higher rolling resistance than low-profile 275/80R22.5 or 295/75R22.5 long-haul tires. Choose 315/80R22.5 when load capacity and sidewall durability matter more than fuel economy.
Hanksugi 315/80R22.5 heavy-haul tires are priced direct-to-fleet at $380-$560 per tire depending on tread pattern (drive, all-position, steer), ply rating (20-ply standard, 22-ply available), and order volume. Full-container pricing (~200 tires per container due to larger tire size) delivers 15-25% savings versus national retail chain pricing for vocational fleets.
Under typical vocational duty cycles (cement, dump, tanker, refuse), a premium Hanksugi 315/80R22.5 drive or all-position tire delivers 90,000-140,000 miles of first life. Vocational miles are harder on tires than long-haul miles — sidewall cuts, curb impacts, and high-torque launches accelerate wear — so mileage expectations are substantially lower than long-haul tires. Casings accept 1-2 retread caps for extended service life.
