This was our TT coming out of a tight turn at a CG. Not only do the tires suffer, the bottom of the spring hangers are forced side to side which also causes the axle to flex somewhat. In some TTs (esp. with the weaker 3-piece welded up I-beams) this can lead to cracks in the frame above the hangers. I lashed a camcorder underneath our TT once and was shocked to see how much the spring hangers flex side to side at every turn.

Whether or not wheel camber changes much in tight turns, frequent dragging of ST tires across the pavement can't be good for them. Must be an even worse issue on triple axle trailers.

I wonder when the wheel camber changes that much at every turn (guessing maybe +/- 5 degrees), that over time there *could* be increased tire wear on the outer portions of the tread leading one to suspect under-inflation?

Maybe the unequal turning radii of tandem axles is an inherent characteristic of them that could be a unrecognized contributing factor in premature ST tire failures and common to any tire brand?

Might have been a good question for the retired tire engineer that used to be allowed on this forum...

This is common on all trailers even big tractor trailers. ST tires are designed with high strength sidewalls just for such circumstances. Obviously some tires are higher quality than others but any of the major brands should be made to a minimum standard for ST tires. Better quality tire mfg's will exceed the standard others will meet it.

Think of your trailer axles and tires a bit like an aircraft wing. They must flex or they dont fly.

The noise you hear from your axles while turning or pivoting on them is normal also and is also experienced by the big freight trailers.

This is really nothing to be concerned about. The only thing that would stop this "twisting" action would be a differential on your trailer axles and they dont need that.
