An axle assembly includes a spindle to receive a drive shaft having a rotational input about an axis and a wheel hub rotatably supported by at least one roller bearing disposed on the spindle. A tire inflation system defines a spindle gas passage to route pressurized gas from an onboard source through the spindle. The tire inflation system includes a seal chamber between the spindle and wheel hub to transfer gas from the spindle to the wheel hub, and a hub gas passage in fluid communication with the seal chamber is arranged to route the pressurized gas to a tire. A lubrication system having a reservoir is located axially outboard of the seal chamber and at least one hub lubricant passage routes lubricant between the reservoir to a roller bearing located axially inboard of the seal chamber. The hub lubricant passage routes lubricant radially outward of the seal chamber.
