I'm not certain on that one. One would think that it would be a matter of spring stretch causing the surges, however, the chain in the spring keeps it from extending. As far as the garden hose I don't want to make the joint too stiff. The surging really is a minor issue, we just noticed because we're new to the whole trailering thing.
I did find this useful:

With a trailer or trike, all of the wear is concentrated on the middle of the tread. If you overinflate the tires, you'll be riding on only the very center of the tread, and it will wear rapidly.
In addition, wheel alignmnent is never going to be perfect. As a result, the paired tires will always "scrub" a bit. If the tires are rock hard, this will cause rapid wear. If the tires are softer, they can flex slightly sideways to accommodate the scrub, without wearing the tread off.
With trailers, severe overinflation can also lead to flipping the trailer over, due to the tires bouncing on road irregularities.
So it could just be that the surging around the corner is a reaction to tire scrub going around corners and that the spring is compensating for it. I don't know. When it comes to trailers I'm no expert.
