Ed--

The wheel bearings are in the SAME location relative to the tire's contact
patch--and the track is the same-- the only differences are the lateral
location of the  wheel mounting flange on the hub and the backset of the
wheel.

There is no change at all in the bearing loading or the steering geometry
when the correct wheels are used with the correct hubs. It's when you start
swapping from single to dual type wheels without understanding all the
details that the trouble starts---
