Trailer Wheel Assembly - Parnells - 20.5x8.00-10 - 8ply - 4 Inch PCD

An 8-ply rating (or Load Range C) indicates the tire's strength and load-carrying capacity, comparable to a tire with 8 layers of cord fabric. It signifies a higher durability and load rating than a standard 4-ply tire.

PCD stands for Pitch Circle Diameter. A 4 Inch PCD means the diameter of the circle on which the wheel's bolt holes are centered is 4 inches. This is a common measurement for trailer hubs.

These wheels are specifically designed for trailers with a 4-stud x 4-inch PCD hub. Ensure your trailer's axle and hub match this specification and that the load capacity meets your trailer's requirements.

These are high-speed rated tires, suitable for highway travel. Always adhere to the maximum speed rating specified by the tire manufacturer, typically found on the tire sidewall or product documentation. For general use, avoid exceeding 65 mph unless specified otherwise.

Each wheel has a load capacity of 605kg. For a dual-axle trailer, the combined capacity of both wheels is 1210kg. Ensure this is greater than the expected weight of your trailer plus its cargo (Gross Vehicle Weight).

Typically, wheel assemblies include the wheel and tire only. Trailer wheel bearings, seals, and dust caps are usually purchased separately and must match your trailer's axle and hub specifications.

Check lug nut torque. Ensure the wheel is properly seated on the hub. Inspect tires for uneven wear or damage. Consider having the wheel balanced if the issue persists.

Check for punctures or embedded objects. Inspect the valve stem for leaks. Ensure the tire is properly seated on the rim. Check lug nut tightness, as a loose wheel can cause leaks.

Ensure proper tire inflation. Check wheel alignment if applicable. Verify lug nuts are torqued correctly. Consider having the wheel balanced.

Check wheel bearings (not included with assembly) for wear or lack of lubrication. Ensure lug nuts are tight and the wheel is not rubbing against any part of the trailer.
