10PLY – 10-ply rating (typically Load Range E), designed for heavy-duty trailer use with a load capacity of around 2,830 lbs (1,284 kg) per tire at the recommended pressure.
BLACK MOD – A black-painted modular steel wheel, featuring round ventilation holes.
15X6 – Wheel dimensions: 15-inch diameter and 6-inch width.
6 ON 5.5 – Bolt pattern with 6 lug holes spaced on a 5.5-inch bolt circle, a common trailer hub pattern.
Function: This assembly is designed for trailers, such as:
Utility trailers
Boat trailers
Equipment trailers
Cargo trailers
Camper/RV trailers
Its purpose is to provide a durable, high-load-capacity wheel and tire combination for safely carrying heavy loads while towing. The radial construction improves highway performance, reduces heat buildup, and generally provides longer tread life than bias-ply trailer tires.
