On my 90 Dodge Ram B250 Roadtrek, I'm getting road wander from having a rear wheel track width 4 inches smaller that the front track width and I'm trying to line things up and I'm trying to figure out what I'm working with and what my options are. My hubs are 89.66 mm measured (rounded up to 90mm). I can't find centric rings with an 90mm ID for the center bore on an Aftermarket wheel. What are the your guys using?
