UNITRAILER steel rim black 5ATx8"H2 3x90 ET:-11.23

The 5AT×8"H2 3×90 black steel rim is a solid rim designed for wheels used primarily in light trailers, transport carts, garden machinery, municipal equipment, and specialized utility equipment. The rim has an 8-inch mounting diameter and a width of 5.0 inches , ensuring stable tire seating and proper wheel operation in everyday use.

It is designed for tires with an 8-inch mounting diameter , such as 16x6.50-8, 16x7.50-8, 18x6.50-8, 18x7.50-8, or 18x8.50-8 , as well as other models with the "-8" designation designed for 8-inch rims. Thanks to the 5.0-inch rim width, it will work best with tires of similar width, provided you follow the tire manufacturer's recommendations.

The rim is made of steel , providing high mechanical strength and resistance to workloads. It features a black paint finish that protects the surface from corrosion and environmental influences. This makes the rim well-suited for utility applications where the wheel operates in variable terrain.

This model has a 3x90 bolt pattern , meaning the rim has three mounting holes arranged in a 90mm diameter circle. Bolt spacing is a key parameter when selecting a rim to ensure proper fitment to the vehicle's hub.

This rim is primarily used on tent trailers, lightweight cargo and luggage trailers, transport carts, and small utility vehicles . It can be used as a replacement on compact camping, garden, and transport trailers, as well as on municipal machinery, golf carts , and groundskeeping equipment. With an 8-inch diameter and 5-inch width, it performs well in applications requiring a stable, small-diameter wheel, a low loading height, and the ability to mount a wider tire. The rim can also be used on trailers towed by ATVs and compact tractors , particularly in gardening, forestry, and off-road applications, provided the bolt pattern, center bore, ET, and recommended tire size are compatible.

Rim offset (ET) is a parameter defining the distance between the rim's mounting surface and its centerline, expressed in millimeters. The ET value determines how deeply the rim sits in the wheel arch. With a positive ET, the rim sits deeper in the wheel arch, while with a negative ET, it protrudes further outward. Correctly selected offset is crucial for vehicle handling stability, avoiding friction with suspension components, and ensuring the vehicle's attractive appearance.

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

The "AT" rim flange profile designates a special rim shape used on small utility, gardening, agricultural, and transportation rims. This design ensures proper tire seating on the rim and stability during operation. The AT profile is primarily used on small-diameter rims intended for work equipment, trailers, transport trucks, and utility machines.

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 fitment to the vehicle's hub. The H2 rim cross-section profile is a double-hump rim. This profile provides even greater tire protection against detachment. This is especially important for sporty, off-road vehicles, or those subjected to higher lateral loads.
