Farmflex wheel 300x100 semi-pneumatic Novio, 20 mm bearing axle Ø20mm NL90mm
Product.Nr.: 990016755
Manufacturer: Novio
This Farmflex wheel from Novio Series 55 is a robust, semi-pneumatic wheel for use in agriculture and horticulture. Thanks to its semi-pneumatic (partially air-filled) design, it combines good damping characteristics with high puncture resistance. The sturdy steel rim in flame red RAL 3000 and the double ball bearing provide a durable, smooth-running solution for agricultural machinery, trailers, garden equipment or special industrial applications.

Benefits and applications
The semi-pneumatic Farmflex wheel offers a good combination of ride comfort and durability. Due to its semi-pneumatic construction, no conventional air pressure is required, which significantly reduces the risk of flat tyres. The double ball bearings (type 6204 2RS C3) ensure smooth, easy running even under frequent use and medium loads up to 70 kg.
Typical applications include agricultural machinery, hay and forage equipment, small trailers, yard and stable equipment as well as machines for gardening and landscaping. Wherever a reliable, low-maintenance wheel with good damping and a sturdy steel rim is required, this Novio Farmflex wheel is a suitable choice.
Explanation of technical terms
- Semi-pneumatic / half pneumatic: The tyre is not fully air-filled like a conventional pneumatic tyre, but has a special rubber structure. This provides basic suspension while making the tyre less sensitive to punctures and flats.
- Load capacity (kg): Maximum load that a wheel may permanently carry under proper use.
- Ball bearing 6204 2RS C3: Standard deep groove ball bearing. “2RS” means double-sided sealing against dirt and moisture, “C3” stands for increased internal clearance, suitable for higher speeds or temperature differences.
- Inch size: Common size designation for tyres (e.g. 4.00-8). Here no separate inch size is specified; the decisive values are the millimetre specifications for diameter and width.
- LI (Load index) and SI (Speed index): Standardised codes for vehicle tyres indicating maximum load capacity and permissible speed. For this semi-pneumatic wheel, no LI and SI values are specified, as it is primarily designed for work equipment and not for road traffic.
- Air pressure (BAR): Recommended filling pressure for pneumatic tyres. For semi-pneumatic wheels this specification is omitted, as they operate without regular air pressure.
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.
To choose from: complete wheels.
Note: Our complete trailer wheels are not balanced — this is not usually necessary for car trailers.
