Another thought here. Rear tires don't just wear from extra weight ( down force). But pulling the extra weight of the pull force. Even though you equalize the weight with the hitch you are still pulling the same weight. Therefore your tires need to work harder.

I like the tire slipping idea.
If your bars are to stiff there is no flex or give
Then your shocks are rendered useless or can't adsorb properly thus on a bump your tire could skip without notice. Even a 1/2 inch or so of slip will Start to wear.

Rotate tires and change your bars.

550 bars would be the best choice, because of the HD and then some, tow vehicle.

The other thing to consider is: what tires do you have. C D or E rated tires? You will get a longer life from an E tire but a harder ride.

some good thoughts here, i doubt i have "slippage" after all my drive axle has 4300lbs... but it is the drive axle so i guess it makes sense it does wear more...

the one worn tire on the trailer might have been from an accident (a car hit my trailer) but i did drive some 500 miles after that before checking alignment (and having the trailer repaired)

i just had my bearings repacked in that process they did check alignment brakes etc... and nothing showed wrong... i have a new tire on there now so time will tell...

in regards to the hitch, i'm just reluctand to drop some $500 on trying out lighter bars... i need to buy an entirley new hitch system because of the bar size...

Your drive axle weighs 4300 when sitting level. When the rig goes through a dip the weight bars lift the axle. Ever see the picture of the Olds Toranado pulling the Airstream with the rear wheels of the car removed?
