Transeagle ST Radial II Premium Trailer Tires

The Set of 4 Transeagle ST Radial II tires are designed for trailer use with a 12-ply construction, providing high load capacity suitable for heavier tow jobs. With a Load Range F and ST sizing, they emphasize highway performance and even wear under demanding highway speeds. These tires are positioned for trailers that require robust durability across long trips, with strong resistance to impact and improved tread life expectations for highway-ted hauling. Observers should confirm they fit their axle and rim configurations before mounting, as the listing focuses on tire capability for trailer use rather than wheel assemblies.
GarveeTech Trailer Tire On Rim 4.80-12

GarveeTech offers a 4.80-12 tire on a 12-inch rim, featuring a 6PR, load range B, and a recommended 60 PSI maximum. This option emphasizes trailer-ready configurations where a rim-tire assembly is preferred for quick replacement or wheel conversion. The product guidance stresses verifying compatibility including rim diameter, lug pattern, and overall diameter against your trailer’s specifications. It is best for smaller trailers, utility setups, or spare tire configurations where a compact, reliable tire/rim package is desired for towing versatility.
MERXENG 4.80-12 Trailer Tire Set With Rim

This MERXENG set includes two 4.80-12 trailer tires with rims, designed for light-to-mid load trailers. The listed features emphasize a 6PR, load range C, and compatibility with five-lug hubs on 4.5-inch bolt patterns. The overall diameter and section width are tuned for trailers that require steady weight distribution and predictable handling on the road. As with any rim-inflated setup, ensuring correct bore size and bolt pattern is essential before installation to maintain safety during towing.
MERXENG 12-Inch Rim Premium Trailer Tires

The 2-pack 4.80×12 trailer tires paired with a 12-inch rim deliver a practical solution for smaller trailers requiring a compact, robust setup. With a 5-lug pattern on a 4.5-inch bolt circle, these tires are oriented toward easy pairing with older or compact trailers. The load range C and 6PR construction provide acceptable payloads for utility and light-duty cargo trailers, along with a balanced highway performance profile. Prospective buyers should check blade-to-axle compatibility and ensure the rims match the trailer’s wheel hubs.
Mastertrack UN203 ST235/80R16 12 Ply Tires

The Mastertrack UN203 tires provide a corresponding 12-ply construction with ST235/80R16 sizing and a Load Range F. This selection highlights all-terrain performance alongside all-weather traction, aiming to deliver stability at highway speeds and durability for longer towing sessions. A three-year road hazard warranty emphasizes reliability for trailers used in diverse environments, from utility setups to boat trailers. For buyers, verifying compatibility with dual-axle spacing, wheel ends, and fitment within overall trailer geometry is advised.
Buying Guide: Key Purchase Considerations
- Load capacity and ply rating: For towing heavy loads, prioritize 12-ply tires or equivalent high-load ratings (6PR to 12PR). Confirm the tire’s load index per tire and whether it matches the gross trailer weight (GVWR) and axle configuration.
- Rim compatibility: If buying tires with rims, confirm lug pattern (bolt configuration), center bore, rim diameter, and mounting offset. Mismatched rims can compromise safety and tire life.
- Size and fit: Ensure tire size corresponds to the trailer’s axle spacing, tire diameter, and overall circumference. Inaccurate sizing can cause contact, rubbing, or incorrect load distribution.
- Speed rating and usage: For highway towing, select tires with appropriate speed ratings and stable tread patterns designed for long highway runs. Some 12-ply trailer tires emphasize highway performance and even wear.
- Warranty and support: Consider tires that include road hazard warranties or repair coverage. Warranties provide peace of mind for long road trips and frequent towing.
- Brand and availability: Reputable brands with clear specifications help ensure reliability. Availability of replacement tires or rims should also be considered for ongoing maintenance.
- Maintenance considerations: Regularly inspect tires for wear, check tread depth, and monitor inflation pressure per the manufacturer’s recommendations. Proper inflation supports safety and tire longevity under heavy loads.
- Compatibility with trailer accessories: If using rim-mounted tires, verify compatibility with existing hubs, spacers, and axle assemblies to avoid installation issues.
