PU tyre + wheel 4.00x8 block Novio 100kg roller bearing Ø20 red NL75mm
Product.Nr.: 990016751
Manufacturer: Novio
This high-quality PU tyre + wheel from Novio is the ideal solution for applications in agriculture, garden and park maintenance as well as transport and light industry. The puncture-proof polyurethane tyre with block tread offers a reliable, low-maintenance alternative to pneumatic tyres and impresses with smooth running and stability at low speeds. Thanks to the robust red plastic rim and the integrated roller bearing, the wheel is ready for installation and is perfectly suited for wheelbarrows, garden carts, transport trolleys and similar equipment.

Benefits and applications
This PU wheel is specially designed for slow-running equipment up to 4 km/h and, thanks to the foamed PU tyre, offers a clear advantage over pneumatic tyres: no flats, no re-inflating and constant load capacity. The hardness of 85 Shore A provides a good compromise between cushioning and stability, ideal for uneven surfaces in the garden, yard or workplace.
The block tread ensures good grip on soil, grass and solid ground, while the robust plastic rim is corrosion-resistant and lightweight. With a 20 mm bore and 75 mm hub length, the wheel can easily be retrofitted to many common wheelbarrows, carts and transport devices or used as a replacement wheel.
Explanation of technical terms
- Tyre type PU: PU (polyurethane) is a foamed, puncture-proof material. It contains no air like conventional pneumatic tyres and therefore cannot go flat.
- Block tread: A block tread consists of rectangular tread blocks that provide good grip on various surfaces while still rolling easily.
- Inch size: Indicates the rim diameter in inches (1 inch = 25.4 mm). Here 8 inch.
- Hardness Shore A: Indicates the rubber hardness. The higher the value, the harder the material. 85 Shore A stands for a relatively firm but still cushioning material.
- Roller bearing: A bearing with rolling elements (e.g. balls or rollers) that ensures smooth running and reduced wear on the axle.
- Load capacity: The maximum load that a wheel may safely carry. Here 100 kg under intended use.
- Max. speed: Maximum permissible speed at which the wheel may be operated, here 4 km/h (typical for hand-guided equipment).
Frequently asked questions about this product
To find a suitable complete wheel, we need five pieces of information:
- Tyre size — shown on the sidewall of the old tyre, for example 195/50 R13.
- Number of holes and bolt circle diameter — how many wheel bolts and what is the bolt circle diameter. For a four-hole pattern, measure from the centre of one hole to the centre of the hole directly opposite. With a five-hole pattern, this isn’t possible directly because no hole is directly opposite — in this case, it helps to check the vehicle documents or a photo of the back of the rim.
- Offset (ET) — see below.
- Hub bore (centre hole) — the diameter of the opening in the centre of the rim.
- Load capacity — the load index must match the axle load, and must be at least the value stated in the vehicle documents.
What the offset (ET) does: It indicates how far the contact surface of the rim is from the centre of the rim, and thus determines how far the wheel protrudes outwards or inwards. An ET that is too small will cause the wheel to rub against the outer edge of the mudguard; one that is too large will cause it to rub against the brake or the frame on the inside.
Reading the offset: It is usually stamped on the inside of the rim, for example ‘ET30’. If there is no stamp, measure it yourself.
Measuring the ET yourself — here’s how:
- Remove the wheel and lay it flat, ideally with the outer side facing downwards.
- Measure the total width G of the rim: from the outer edge of one rim flange to the outer edge of the other. Half of this distance is the centre of the rim.
- Measure dimension A: place a straight ruler across the top rim flange and determine the distance from this edge to the hub contact surface — that is, to the surface that rests against the vehicle.
- Calculation: ET = A − G/2
Example: Total width 230 mm, measurement A 145 mm. Centre of the rim = 115 mm. ET = 145 − 115 = 30. A positive result means that the contact surface lies outside the centre of the rim — this is the normal case. A value of zero means it is exactly centred, whilst negative values indicate it lies further inwards.
The quickest way is still to take a photo of the back of the old rim — this shows the bolt pattern and usually the embossed dimensions as well.

Note: Our complete trailer wheels are not balanced — this is not usually necessary for car trailers.
