Default Komet trailer tires

Double axle trailers do sway, and are in general more unwieldy than single
axle trailers. A poorly designed trailer will sway at lower speed, adding
an axle seems to increase the speed at which it goes wrong


Wow, does that go against everything I know to be true about trailers.

That same tire scrubbing you talked about while going around a corner is
exactly what makes the dual axle trailer more stable, if ALL other factors
were equal. Vortex shedding can certainly be a big issue, as is percentage
of tongue weight to overall trailer weight.

Many dual axle trailers do not carry enough tongue weight. Some also do
not have both springs mounted on a common pivot, which is not the correct
way to rig 2 axles.

Another factor against many glider trailers is that too much mass is too far
behind the axles. Any weight put further out behind the axle contributes to
dynamic instability, even if the tongue weight is correct.

I know having the axles further back makes cornering a more difficult issue,
but it really does help with stability, on the whole.

If you disagree with what I just posted, you and I will have to agree to
disagree, I guess.

Sunny skies!
