The kit contains: Two 145R10 Trailer Wheels with Wanda WR068 tyres fitted on 4 x 100 PCD metric rims. These are high-speed radial trailer tyres on heavy-duty steel rims and are E-Marked for legal use on European roads. Tyre Specification: Tyre Diameter: 492mm, Tyre Width: 147mm, Tyre Pattern: WR068, Tyre Brand: Wanda, Tread Depth: 7mm, Load rating: 84/82 = 500kgs for single axle & 475kg for dual axle, Speed Rating: N = 140km/h (86mp/h), E-Mark Number: E4-0036064. Rim Specification: Rim Size: 3.50x10, Rim Finish: Powder coated Steel (Grey), Pitch Circle Diameter: 100mm PCD (metric), Centre hole size: 60mm, Rim Offset: Zero. The kit also includes two High Speed Hub & Stub Axles, manufactured in the EU by 'Steelpress Production'. These axles are road legal, rated up to 130km/h and feature sealed precision ball bearings. The hub has 4 x M12 studs with a 100mm PCD. The shaft is 35x35mm square, 200mm long, and has a weight capacity of 750kg per pair. Additionally, the kit includes one pressed steel tow hitch, suitable for 750kg, with a zinc-plated finish. It fits over a 50x50mm box section and is secured by two M12x70mm bolts (provided). These hitches comply with Regulation 55 of the UNECE and are designed for coupling with class A ball hitch couplings.
This Parnells trailer kit is designed for individuals and businesses needing a robust and road-legal wheel, axle, and hitch solution for trailers with a 750 kg capacity. Its key benefit is providing a complete, high-speed rated assembly with E-Marked components for European use. A potential consideration is that the specific tire size (145R10) may require matching to existing trailer dimensions.

FAQs
What is the maximum speed rating for this trailer kit?
The tires and axles are rated for a maximum speed of 140 km/h (86 mph), indicated by the 'N' speed rating.
Are the components legal for use in the UK and Europe?
Yes, all components, including the tires and axles, are E-Marked, ensuring they meet regulatory standards for legal use on European roads.
What is the total load capacity of this kit?
The kit is designed for a total trailer weight capacity of 750 kg. The load rating per wheel is 500 kg for a single axle setup and 475 kg for a dual axle setup.
What type of bearings do the axles have?
The axles feature sealed precision ball bearings, which are designed for low maintenance and reliable operation without the need for frequent greasing.
How do I attach the tow hitch?
The pressed steel tow hitch fits over a 50x50mm box section and is secured using two M12x70mm bolts, which are provided with the kit.
Can I use these wheels on a trailer with a different PCD?
No, these wheels have a 100mm PCD (Pitch Circle Diameter) and are specifically designed for hubs with the same 100mm PCD and 4 x M12 studs. Using them on a different PCD may compromise safety and legality.
What is the rim specification?
The rims are 3.50x10 size, made of powder-coated steel in grey, with a zero offset and a 60mm center hole size.
Troubleshooting
Trailer pulls to one side
Check tire pressures are equal on both sides. Inspect axles for any signs of bending or misalignment. Ensure wheels are correctly seated on the hubs.
Wobbling or vibration at speed
Verify wheel nuts are fully tightened. Check tires for bulges or damage. Ensure wheels are balanced if possible, or check for bent rims.
Tow hitch feels loose or noisy
Ensure the hitch is correctly fitted to the 50x50mm box section and securely bolted. Check the coupling mechanism for wear and lubricate if necessary.
Tires showing premature wear
Check wheel alignment and ensure the trailer is not overloaded beyond its 750kg capacity. Verify correct tire pressure. Inspect for any rubbing against the trailer body.
Pros and Cons
Pros
Provides a complete, ready-to-install trailer component package.
High-speed rating suitable for highway and long-distance travel.
E-Marked components ensure legal compliance across Europe.
Durable construction with heavy-duty steel rims and EU-manufactured axles.
Low-maintenance design with sealed precision ball bearings.
Cons
Tire size (145R10) might not be a direct replacement for all trailer applications.
Specific load rating for single vs. dual axles needs careful consideration (500kg single, 475kg dual).
The tow hitch requires a 50x50mm box section, limiting compatibility with some trailer frames.
Setup, Compatibility & Care
Setup:
Mount the provided pressed steel tow hitch onto the trailer's 50x50mm box section frame using the two M12x70mm bolts (provided).
Attach the hub and stub axles to the trailer chassis. Ensure the 35x35mm square shafts are securely mounted and the 100mm PCD hubs are oriented correctly.
Mount the pre-assembled wheels (tyre on rim) onto the hub studs, ensuring the 4 x M12 studs align with the rim's holes. Tighten lug nuts securely.
Compatibility:
Axles: The 35x35mm square shaft axles are designed for trailer chassis frames that can accommodate this profile. The 100mm PCD hubs are compatible with wheels having a 4-stud pattern on a 100mm circle.
Hitch: The tow hitch is designed to fit over a 50x50mm square box section and is compatible with Class A ball hitch couplings.
Tires: The 145R10C tires have a diameter of 492mm and a width of 147mm. Ensure clearance within the trailer's wheel arches.
Care:
Tires: Regularly check tire pressure and condition. Ensure tread depth remains adequate and inspect for any signs of wear or damage. Rotate tires if uneven wear is observed.
Bearings: The sealed precision ball bearings are designed for low maintenance. Avoid disassembling them unless absolutely necessary. If any roughness or noise is detected, consult a professional.
Hitch: Keep the tow hitch mechanism clean. Lubricate the ball coupling area sparingly if required for smooth operation. Check the hitch for any signs of wear or damage before each use.
General: Clean components with a damp cloth. Avoid using harsh chemicals. Periodically inspect all bolts and connections for tightness.
