Steel rim for trailer STARCO 4Jx13" 4x130 ET:20
Steel trailer rim STARCO 4Jx13" 4x130 ET:20
The STARCO 4Jx13" steel rim is the perfect solution for lightweight trailers, such as cargo trailers, garden trailers or trailers for transporting recreational equipment. The 4-inch wide rim with a diameter of 13 inches, a 4x130 bolt pattern and an ET:20 offset, ensures stable and safe trailer handling. Thanks to its solid construction and maximum load capacity of 450 kg , this rim is perfect for everyday use, where moderate goods are transported. It is a reliable choice for those looking for durable and strong components for their lightweight trailers. The 4x130 pattern means that the rim has 4 mounting holes, which are arranged on a 130 mm diameter circle. The bolt pattern is a key parameter when selecting a rim to ensure that 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 critical to proper tire seating, tire installation, and overall fitment to the vehicle hub. The H-shaped rim cross-section profile is a rim with a single hump on the inner side of the rim. This hump helps prevent the tire from slipping off the rim, especially when driving with low tire pressure or during sudden maneuvers.
