Complete wheel 18x9.50-8 DURO HF-255 4PR tractor right, wheel connection 4 x 100mm
Product.Nr.: 990016600
Manufacturer: DURO
This DURO complete wheel 18x9.50-8 from Series 58 is specially designed for tractors and equipment used in agriculture and horticulture. The robust HF-255 tyre with 4PR is tubeless (TL) and is already ready to run, mounted on a one-piece grey steel rim. Thanks to its sturdy design, high load capacity and low permissible speed, this wheel is ideal for work machines that need to be used reliably and safely around the farm, in the field and on grassed areas.

Advantages and application area
This complete wheel is developed for heavy continuous use on tractors and farm and garden equipment. The HF-255 tread provides good grip on meadows, fields and unpaved roads without excessively damaging the ground. The 4PR carcass offers a balanced combination of stability and ride comfort, while the tubeless (TL) design eliminates the risk of inner tube damage and simplifies maintenance.
With a maximum load capacity of 430 kg and a permissible speed of 15 km/h, the wheel is ideal for slow work vehicles, trailers and implements in agriculture and horticulture. The robust steel rim with 2,0 mm material thickness and one-piece design ensures a long service life, even under demanding operating conditions.
Explanation of technical terms
- TL (Tubeless): Tubeless tyre that is mounted directly on the rim without a separate inner tube. Advantage: less prone to punctures and easier to maintain.
- PR (Ply Rating): Indicates the tyre's load rating class (here 4PR). A higher number stands for a stronger carcass and higher load capacity.
- Inch size: Indicates the rim diameter in inches (inch). Here 8 inch.
- Speed index (SI): Identifies the maximum permissible speed of the tyre. A3 corresponds to a maximum speed of 15 km/h.
- Offset (ET): Distance between the rim centreline and the rim's mounting face on the hub. ET-2 affects the track width and the wheel position in the wheel housing.
- Bolt pattern 60/100/4: Describes the rim's mounting dimensions (e.g. PCD and centre bore), important for correct fitment to the vehicle.
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.
