trailer wheel wobble

[barend]

well, not quite trailer, sidecar really. My leaning sidecar came originally with a 480x8 wheel with integral hub, I am upgrading this to a separate hub and wheel combo from Northern Tool. Here's the rub, when I install everything there is a hump like you would have on a spoke wheel with the spokes adjusted wrong.

 

If the swingarm is somehow not perfectly even, would the tire not still track straight albeit under an angle

Am I correct in assuming that if the hub is cast incorrectly the whole wheel would run under an angle?

Could the wheel rim be warped?

What would the effect of this (sideways) wobble be at high speed with this size tire?

 

I am trying to get the side car back on the bike and run it before next weekend's March on Rome, so I am kind of pushing on this to get it re-attached and aligned.

 

Thanks for any feedback! And have a great Labor Day weekend!!
