WDH transfer to trailer axle

Campadk suggests a 750lb total hitch weight, for 188 lbs per tow vehicle tire. Sounds reasonable, but may I suggest that it should be less than that, if (and maybe that's a big "if") the WDH is properly adjusted. With a relatively short 19' trailer, the theoretical weight transfer back to the trailer axle should be well over 30%, leaving about 500 lbs on the tow vehicle (my 125 lbs per tire). This effect diminishes with longer trailers.

Or could those of you who have experimented with this comment on whether this theoretical effect actually happens in the real world?

I think it's important to understand this because there are plenty of tow vehicles with fairly modest payload capacities when actual curb weight is subtracted from GVWR, especially if they are heavily optioned with "comfort and convenience" features and owners intend to carry a full load of passengers and gear.

hi albertF

you're right of course. there will be some load carried by the trailer tires...
i recall somewhere, in reading campadk posts, he planned to use 600lb bars so IF the tongue load comes in higher...it will ride on the rear tv wheels...

and i think we are all keeping in perspective the overall size issues here...

this is a small trailer...and they only plan a few trips this fall...

however the exercise may help others trying to match tv to trailer to tire....

so every angle on the issue helps...

my scale visit followed just your observation...with a 34 not much was moved to the trailer axles...

i'm just excited to read from someone who is getting the new retro cool model...

these folks are gonna be required to post photos big time...for the rest of us.

and they are riding BICYCLES today...till the yukon comes home!

isn't this all so much fun!

cheers

these are yukon denali xl models right? 4x4 2003?

originally came with either 265/70/16s or 265/70/17s....

i suspect the smaller size because of the smaller engine.

anyway the 275/55/20s DO increase osd from 30.6 inches to 31.9 inches...

-this is roughly 4% larger. so hp/torque to the ground is reduced by approximately this much.

Good point 2air! I'll be sure to compare the OSD tommorrow.

Thanks

will .Have you ever seen any jeep vehical in snow with wide performance
low profile tires on it? Those tires are for dry roads and grip on dry pavement
thats it.They are poor in the rain ,you will be out in the rain sometime .

good luck in your decision.

Nope... the wider tires are the 'summer' tires. I just call the guy an hour agao, and apparently the other tires are not snow tires, they are a true SUV, light tire..er... tire. Will check them out tommorrow.

already the idea is that they are snow tires ,good grief someone goning to get hurt ,and I hate for that to happen ,and to say that you will only drive
on the sunny days is hard to understand .Those eagles are half as tall as the
michelins , I have had experience with the impalas tires in the rain ,I have to drive slower than should be needed ,and when i hit a puddle on the freeway
i have to hold the wheel ,they are 255 75 R 17 inch wide and slippery and
have made me real uncomfortable ,I have pulled our trdwnd in the pouring
nebraska rains at 55 mph with 31 10-50 15 tires BFgoodrich all terraines and
never ever experienced any problems with the weather .I run 15x8 steel wheels .Im not bragging by no means ,but safety is my primary towing concern as it should be for everyone.

Bit of miss understanding. The wider 20" are the 'summer' tire. Other set (16"'s) are the original pair which I thought were 'snow tires' but are in fact all season light truck tires. I imagine he used the original 16" for his winter driving, at it should be.

LOL.. yup today we had to walk around everywhere! I felt naked without a set of car keys on me.. scarey!

No worry on the photos 2air... we take TONS of photos.. I probably have over 200 of just our small teardrop. No doubt like the tear, I'll be setting un overly detailed site for our '40 Winker' including everything I hopefully learned.

As you mentioned we are doing a few short trips this fall before the snow flys. Probably will average about 8 trips a summer, most within a 3-4 hour drive. The primary purpose of the TV is NOT towing. We do about 26,000 km of driving per year (mainly highway as we work from the home office), about 6,000 km or about 23% of our mileage will be for towing the Bambi.

See you on the bike path tommorrow
