Advantages and applications

With its material thickness of 4.0/4.50 mm, this steel rim offers high stability and durability, even under heavy loads up to 900 kg. With an approved maximum speed of 140 km/h, it is suitable both for road use (e.g. trailers) and for faster work vehicles.

The mounting pattern 115/165.1/5 allows use on vehicles and machines with a corresponding multi-hole mounting pattern. The 80° tapered seat at the back hole ensures a secure seating of the wheel nuts. The standardised valve hole of 11.5 mm (+/-0.2) allows the use of common valves. The grey paint protects the steel rim against corrosion and gives it a discreet, professional appearance.

Typical applications include:

• Industrial trailers and transport trolleys
• Municipal and garden equipment (e.g. equipment trailers)
• Agricultural equipment and machinery with matching bolt circle

Explanation of technical terms

• Inch size: Indicates the rim diameter in inches (here 12"), important for selecting the correct tyre size.
• Rim 4½Jx12H2: "4½J" describes the rim width and the contour of the rim flange, "12" the diameter in inches, "H2" stands for a double hump design that secures the tyre better against slipping.
• ET (offset): Distance between the centreline of the rim and the contact surface at the hub. ET0 means that the contact surface is exactly in the middle of the rim; this affects track width and clearance on the vehicle.
• Mounting pattern 115/165.1/5: Describes the mounting pattern of the rim (centre bore/pitch circle/number of holes). Here it means a multi-fit pattern with pitch circles of 115 mm and 165.1 mm and 5 fixing holes.
• Back hole with 80° tapered seat: The back hole is the bore for wheel fastening; the 80° tapered seat ensures a positive and secure seating of the wheel nuts or bolts.
• Load capacity 900 kg: Maximum static and dynamic load that the rim can safely carry per wheel.
• Valve hole 11.5 +/-0.2 mm: Bore for the tyre valve; the specified tolerance (+/-0.2 mm) ensures compatibility with standard valves.
• Max. speed 140 km/h: Upper limit of the permissible speed up to which the rim may be safely operated within the approved load range.
