Complete wheel 18x9.50-8 DURO HF-255 4PR tractor left wheel connection 4 x 100mm
Product.Nr.: 990016599
Manufacturer: DURO
This DURO complete wheel 18x9.50-8 HF-255 from Series 58 is specifically designed for use on tractors in agriculture and horticulture. The combination of a robust 4PR tyre and a one-piece grey steel rim provides a reliable solution for work at low speeds and moderate loads. The HF-255 tread ensures good traction on meadows, fields and garden areas, while the stable construction supports a long service life.

Benefits and application area
This complete wheel is ideal for tractors and similar machines used in agricultural and horticultural environments. The maximum load capacity of 430 kg and speed index A3 (up to 15 km/h) make it particularly suitable for slow working runs on the farm, in the field and on green areas.
The one-piece steel rim with 2.0 mm material thickness offers high stability and is designed for harsh operating conditions. The bolt pattern 60/100/4 enables suitable mounting on many common tractors and implements. The TL (tubeless) design reduces the risk of tube damage and simplifies maintenance.
The HF-255 tread provides good grip on soft and mixed surfaces and supports safe power transmission when towing, mowing or transporting. The left-hand mounting version is intended specifically for the corresponding wheel positions on the vehicle.
Explanation of technical terms
- TL (Tubeless): Tubeless tyre mounted on the rim without a separate inner tube. Advantage: less prone to tube-related failures, easier maintenance.
- PR (Ply Rating): Indicates the tyre load rating class. 4PR means a reinforced carcass compared with simple passenger car tyres, suitable for higher loads in working operation.
- Speed index (SI): Indicates the maximum permissible speed of the tyre. A3 stands for a maximum speed of 15 km/h.
- Offset (ET): Distance between the rim centreline and the mounting face on the hub. ET-2 describes how far the wheel sits inward or outward in the wheel housing.
- Complete wheel: Combination of pre-mounted tyre and rim, ready to install on the vehicle.
- Bolt pattern 60/100/4: Refers to the rim hole geometry (centre bore, pitch circle diameter and number of mounting holes) and ensures accurate fit to the wheel hub.
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.
