I think the diameter of the wheels goes from 22.5 to 24.5 when you up from the 31,500 axle to the 33,000.  That being said, having a larger diameter wheel in the rear then the front will make the truck sit a little higher in the back naturally, as well as it makes the back wheel look noticeably larger.   I would like to know the story on the spoke style wheels, I thought spoke/dayton style wheels were going away and they actually have a lesser rating then the bud? style wheels.   All the other wheels I've seen on the 33,000 axles are the typical bud style wheels however I did see grapevine texas recently got a similar pierce quint with the spokes on the rear.  

The Dayton style wheel went by the way side in 2002-2003 on all trucks.  Very few were built with the Dayton wheel.
