Steel trailer rim STARCO 5.5Jx14"H2 5x112 ET:30
The STARCO 5.5Jx14"H2 steel trailer rim is a strong and solid rim, ideal for flatbed trailers, heavy trailers such as construction trailers, larger cargo loads, heavy machinery, as well as campers. Its design provides a high load capacity of 1030 kg , making it suitable for applications where stability and safety are a priority. The 5.5 inch wide rim, 14 inch diameter, 5x112 bolt pattern and ET:30 offset provide confident and reliable handling even in more difficult road conditions, being the ideal choice for demanding users of heavy trailers. The 5x112 bolt pattern means that the rim has 5 mounting holes, which are arranged on a 112 mm diameter circle. The bolt pattern is a key parameter when selecting a rim to ensure it fits properly to the vehicle hub.

Rim offset (ET) is a parameter defining the distance between the rim's mounting surface and its axis of symmetry, expressed in millimeters. The ET value determines how deep the rim is embedded in the wheel arch. With a positive ET, the rim is deeper in the wheel arch, while with a negative ET it protrudes more outward. A correctly selected offset is crucial for vehicle handling stability, avoiding friction on suspension elements and ensuring the car's appropriate appearance.

The center bore of the rim is the hole located in the very center of the rim that fits onto the vehicle's hub. Its diameter must match the hub diameter so that the rim is properly seated and centered on the vehicle. The center bore plays a key role in transferring loads from the rim to the hub, which affects driving stability and safety. If the center bore is too large, centering rings are used to ensure a proper fit.

The rim flange profile refers to the shape and design of the rim edge that comes into contact with the tire. The "J" flange is characterized by the appropriate shape and dimensions that ensure that the tire is securely seated on the rim, minimizing the risk of the tire slipping while driving, especially at low pressure or under high lateral loads. This profile is widely used due to its versatility and ability to work with different types of tires.

The rim cross-section profile refers to the shape of the inner part of the rim, which includes both the flange and the surface on which the tire rests. This profile is crucial for proper tire seating, mounting and overall fit to the vehicle hub. The H2 rim cross-section profile is a double hump rim. This profile provides even greater protection against the tire slipping off the rim. This is especially important for sports, off-road vehicles or those that are subject to higher lateral loads.
