How to Choose Sutong Tires

Choose Sutong tires by identifying your application category before comparing models. Sutong company operates as a wholesale importer and distributor rather than a single consumer-facing brand, so the correct starting point is always your equipment type, not tire size alone. 

Sutong handles several exclusive brands - Hemisphere, Hi-Run, LongMarch, Pinnacle, RoadOne, SuperCargo, and Synergy - along with associate brands. Each serves a distinct segment of the market.

For trailer applications, which represent Sutong's core business, SuperCargo and Hi-Run are the primary brands to evaluate. Sutong's core focus is on sourcing and supplying tires, wheels, and assemblies for the utility and RV trailer industry, and its expertise lies specifically in trailer and lawn-and-garden tire categories. ST (Special Trailer) service ratings and load range are the critical specifications to match when selecting within this segment. 

For medium truck and commercial applications, LongMarch and RoadOne are the relevant starting points. Long March (Chaoyang Long March Tyre Co., Ltd.) is a major global manufacturer specializing in all-steel radial truck and bus tires. It is an independent Chinese manufacturer whose products Sutong distributes in North America, not a brand Sutong created. Sutong backs Long March MTR tires with a limited warranty covering defects in workmanship and materials for the life of the original tread down to 2/32".

For lawn-and-garden, ATV/UTV, and light specialty applications, Hi-Run covers lawn and garden equipment and small trailers, while Wolf Pack addresses the powersports segment. Wolf Pack specializes in durable, high-traction tires for ATVs and UTVs used in both recreation and utility contexts, offering all-terrain and aggressive knobbed patterns built with multi-ply construction. Wolf Pack is not a truck or passenger brand. 

For industrial and skid-steer applications, Sutong's SuperStrong line covers forklifts and skid-steer equipment. Products like the SuperStrong skid steer tire are designed for forklifts and scrapers, with a wide footprint and thick tread for maximum contact and traction. 

Sutong is best understood as a specialty wholesale distributor with application-specific sub-brands rather than a broad consumer tire company. Established in 1993, Sutong's global sourcing strategy targets pricing efficiency for dealers and retailers, which means end consumers typically encounter Sutong's brands through retail partners rather than direct-to-consumer channels. Selection should always begin with application family - trailer, commercial truck, ATV/UTV, or lawn and garden - and then narrow to the appropriate sub-brand and load specification.

Popular Sutong Tire Sizes by Application & Sub-Brand

Because Sutong operates as a wholesale distributor with separate sub-brands for each application segment, "common sizes" are best understood by use category rather than by a single catalog. The ST (Special Trailer) service designation and the inch-based lawn-and-garden sizing convention are the two main sizing systems buyers will encounter.

Trailer Tires - Hi-Run & SuperCargo

• ST205/75R15 (Load Range D or E) - the most widely stocked trailer size across Sutong's Hi-Run and SuperCargo lines; sold for boat, utility, and general-purpose trailers.
• ST225/75R15 (Load Range E or F) — a step up in load capacity from the ST205, common on larger utility and cargo trailers. Available in both Hi-Run and SuperCargo variants.
• ST235/80R16 - mid-range 16-inch trailer fitment, found in SuperCargo's ST Radial line for heavier cargo and enclosed trailers.
• ST235/85R16 (Load Range G or H, up to 14-ply) — SuperCargo's heaviest common fitment, used on fifth-wheel RV and large commercial trailers requiring high load ratings.

All ST-rated sizes carry the Special Trailer service designation, meaning they are engineered exclusively for trailer axles - not for drive or steer positions on motorized vehicles. Load range (C through H) and ply rating are the critical selection criteria within this segment, not speed-based performance ratings.

Lawn & Garden Tires - Hi-Run

• 20x10.00-8 (2PR or 4PR) - one of the most common rear turf sizes for residential zero-turn and riding mowers;
• 18x8.50-8 (4PR) - a popular rear mower and golf cart size in the Hi-Run line;
• 24x12.00-12 (4PR) - rear fitment for larger zero-turn mowers (60–72 inch decks); the Hi-Run SU05 in this size is among the top-rated turf tires;
• 23x10.50-12 (4PR) - rear replacement size for mid-range zero-turn decks, available in Hi-Run's turf tread (SU05) and chevron tread (SU12) patterns.

Lawn-and-garden sizes use the inch-based format (diameter × width-rim diameter) rather than the metric format used in automotive tires. Ply rating (PR) governs load capacity; turf tread patterns (SU05) protect grass, while chevron patterns (SU12) provide additional traction on slopes.
