    I just came back from an week long RV camping trip.
    and I usto be able to run 70 ,to 75 mph no prob trailer tracked like an arrow.
    Now I put some 305/65/17/Xtreme M/T tires on .
    She was swaying more than I like @ around 60,65 mph.
    I have sway control but never had a nead for it in the past.
    Now my question is do yall think it is the tires on my truck making it sway or the hitch since the bigger tires raised the truck a little and I did not re ajust the drop on my head?
    the tires on the truck are 10 ply E rated and have almost max air in them.
    The trailer is a 33 ft T/T about 9k lbs.
    Thanks Steve.

    How far off level is the trailer when hooked up?

    That could be part of it, but I am also guessing the extra rubber between the wheel and the ground has to do with it as well. Mine is pretty bad as well, but I only have the BFG's D rated ones. I hate that. Next will be E's. When I tow I tow too heavy for the D's.

    I am using it on the top two holes so its like stock setting I bet you I nead to drop it one setting and on my Bars I only went 3 chains usily I go 4 chains.

    Yeah, try dropping the hitch a bit, I only tow 7,000 pounds and have 315's (E rated) but don't have any problems. But if the trailer is to high, I will feel it a lot more.

    If the hitch is too high then you are putting more of the trailers weight on the rear two tires on the trailer and more tounge weight on you rig. By lowering the hitch mounting down some you will be equalizing the weight on the trailer. Making all four tires on the trailer carry more of the weight. I also tow with 315's and found if the hitch is at the correct height then I have no more problems than I did stock.
