The Parnells 18x9.50-8 Open Centre P328 wheel and tyre assembly is an ideal solution for industrial equipment, utility trailers, and ride-on mowers that require a high-traction, durable wheel setup. Engineered for rugged environments, it features a heavy-duty steel rim and a 4-ply rated tyre, offering reliability for heavy workloads. While it provides excellent stability and is E-marked for low-speed road legality, users should note that its maximum speed rating is limited to 20km/h (A4 rating), making it unsuitable for high-speed highway towing.

No. This tyre is rated A4, meaning it is only suitable for speeds up to 20km/h and is not intended for highway use.
The rim features a standard 4-stud Imperial 4-inch PCD (Pitch Circle Diameter).
No. Exceeding the maximum load of 475kg per tyre can lead to structural failure and is unsafe.
The E-mark signifies that the tyre complies with European and UK safety and manufacturing standards for road-legal use at low speeds.
The tyre should be maintained at 24 PSI to ensure optimal performance and load capacity.
The rim is finished with powder-coated paint and E-coating, which provides significant protection against corrosion and weather exposure.
Check that all wheel nuts are tightened to the correct torque and ensure the wheel is properly seated on the 67mm centre hub.
Verify the PSI is set to 24. Inspect the tyre casing for debris or thorns that may have punctured the tread and check the valve stem for leaks.
Ensure the trailer is not being overloaded beyond the 475kg capacity and verify that the tyre is not being subjected to speeds exceeding 20km/h.
To ensure proper installation, verify that your trailer or vehicle hub utilizes a 4-stud pattern with a 4-inch PCD (Pitch Circle Diameter). When mounting, ensure that the 67mm centre hole seats correctly against the hub flange and that the 12.5mm stud holes align perfectly before tightening the wheel nuts to the manufacturer's torque specification.
Care instructions include regular pressure checks; maintaining the tyre at exactly 24 PSI is critical to meeting the maximum load rating of 475kg. Avoid exceeding the 20km/h speed limit, as high-speed operation will cause excessive heat buildup and premature tyre failure. For long-term storage, keep the assembly in a cool, dry place away from direct sunlight to prevent rubber degradation.
