 Those lift axles are rated around 13,000lbs with lo profile 22.5 rubber, the little axles that you are seeing are 6 lug and only 8,000lb capacity. They tend to wear out faster than the larger axles. Mack had a dump truck in Vegas 2 year's ago with 18,000lb lift axles and 385 super single tire's, was spec'd for an East coast state. Hope this answer's your question?
Cheer's, Neil.
