Thanks to its solid construction and maximum load capacity of 500 kg , this rim is perfect for everyday use, where moderately heavy goods are transported. It is a reliable choice for people looking for durable and strong components for their light trailers. The rim is compatible with various trailer models, making it a universal choice for people looking for reliable transport solutions. Thanks to its carefully designed construction, it offers long-lasting durability even with intensive use, and is ideal for transporting moderately heavy goods, offering reliability and durability. It is an excellent choice for owners of light trailers who need durable and load-resistant rims. The 4x100 spacing means that the rim has 4 mounting holes, which are spread out over a 100 mm diameter circle. The bolt pattern is a key parameter when selecting a rim to ensure it fits properly to the vehicle's 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.
