The Alcoa ULA18x is a 22.5" x 8.25" aluminum wheel engineered for the demands of heavy-duty truck, trailer, and motorhome applications. Constructed with Alcoa’s proprietary MagnaForce® alloy, this wheel offers a lightweight yet durable solution, weighing approximately 39 lbs. It incorporates vHub™ Bore Technology, which minimizes hub-to-wheel contact to reduce corrosion. The wheel utilizes a hub pilot mounting system with 10 bolt holes and a 285.75mm bolt circle, a 26mm bolt hole diameter, and a 220.1mm hub bore. With an outset of 6.6" and an inset of 5.81", the ULA18x is designed for optimal fitment and performance. It boasts a maximum load capacity of 7400 lbs and can handle a maximum cold inflation pressure of 130 psi. The wheel comes equipped with a TR554D valve stem. This wheel is ideal for those seeking advanced innovation, manufacturing, and engineering on the road. Its design also accommodates for aerodynamic drive covers through a proprietary flange mounting design, making it a lightweight champion for commercial vehicles. Various finishes are available, including Mirror Polish, Dura-Bright, Brushed, and Dura-Black, offering aesthetic customization to match application needs.
