What if trailer is over 15% TW?

Just wondering if there would ever be towing problems if a TT is loaded too far forward and over the ideal 10%-15% TW?

I know overloading to the rear of a trailer axels, and having under 10% TW, potentially will cause sway.

Assuming a trailer is UNDER its GVWR, the WDH is UNDER max wt, the TV PL & RGAVR is UNDER max wt, TV is level & front fender at an identical height as if no trailer attached -

Would there ever be towing issues if all specs were within limits but the TW was 20%-30% or even more?

Is 10%-15% just a 'sweet spot'?
  • From a performance standpoint, if you have a SW trailer, I have had some bounce more from speed bumps or equal when the HW is above 15%, ie closer to 20, which is common in open utility trailers Like I have used over the last 30+ years in my landscape maintenance biz. Mowers etc in front of the trailer, nothing in the rear.

    Other than that, if the trailer is level, and a dual axel, not an issue either.

  • Too much tongue weight will cause stability/sway issues just like low tongue weight will! Ask me how I know.

    12% is the best number to be at for tongue weight.

    Here is a video that demonstrates how too much TW effects stability. I've seen another video done with a demonstrator like this where they move the same weights to the back, then the middle and finally the front.

  • It depends.

    I like a heavy tongue weight. When towing my race car trailer I can put the TW anywhere I want. I've gone up to 20% and it tows great. But I also have a heavy diesel up front which can balance things out.

    I like to get my TV weight 50/50 on the front to rear. This is the best it can get for handling.
  • A slightly high TW will not cause sway but a severely high TW can. If you're thinking you're running high it would be worth a trip to the scales to find out. Don't want that a-frame separating either.
    Happy travels!
