I just wanted to verify something. I've had an F-150 with the max trailer towing package since 8/24. Towed my 7 by 14 cargo trailer about 500 miles so far. It feels like it's wiggling around back there while under way. The trailer's loaded the same way it was behind my '95 Ram and I never knew it was behind me then. I even put more weight in the front to increase the tongue weight, thinking that might have something to do with it, without any luck. I've towed it nose down, and level too. The Dodge has P245/75-16 Dunlops on it, while the new truck has the Michelin P265/70-17. Is it the Michelin brand, the 70 series tire or a combination of both?

 

Your max tow package with the integrated brake controller has computerized sway control. It may be that you are feeling the sway control working. It feels like the rear of the truck is moving around as the computer applies the brakes on individual wheels. I have noticed this with my 2011 F250 and it is disturbing. I now turn the sway control off when towing and life is good once again. This has to be done every time you hit the tow/haul button.

 

Thanks, I'll try that next time.

 

Well I think one thing that needs to be looked into in my depth is the tire.

I'd switch to LT tires and make them E-rated.

will give you a stiffer sidewall and you won't have to worry about overloading them.

In the mean time check your air pressure and increase it to the max on the sidewall when towing.

Be sure to check the sidewall for the max payload on them too.

 

Agree, I have towed much bigger trailers than the OP's with my 2010 F150 and no problem at all. Did something change for 2011?

I'm going to make sure the air pressure in all the tires is maxed out and see how that feels. Then I'll turn off the sway control and see if it feels different. I think the Michelins have too much give in the sidewalls. I was curious to see if anyone else using the Michelins felt the same way or not. With a kid away at college and new truck payments on the way, a new set of tires is kind of not an option at this time. It's never felt like anything was seriously out of control back there, just this annoying wiggle and bumping. Discount Tires has a Dunlop 245/75-17 LT that would probably work really well.

They would probably work but the website does not say much other than what you put down. Worth investigating though.
