I recently had AT tires put on my 21 Lariat with 700 miles. The tires are same size as factory. The dealer also did an alignment. I noticed on my highway drives that Im fighting the lane centering more now. Before the tire change it would go down the road straight as an arrow and Id get the "put your hands on the wheel" message constantly because it drove so straight I never had to make any input adjustments. Now, with the new tires, I noticed Im fighting the wheel a lot more than before. I dont get the "hands on the wheel" message much because Im making so many steering inputs. Also, I now occasionally get a warning that Im near the left line on the road even though Im not. I asked the dealer about it and they seem unsure. I think they are confusing lane centering with lane keeping. I can understand this since this is the first year the F150 has lane centering. Has anybody else had this issue? I know, when I had my Audi, the dealer told me that if an alignment was done, the camera system had to be recalibrated. Absolutely love the truck, BTW!

Thanks

 

Could just be the way the AT tires track on road crown or seams. You shouldn't need any recalibration if you only changed tires with something the same diameter (and didn't do any suspension changes).

 

If someone finds a way to adjust the Lane Centering let me know. Lets just talk interstate driving, I-75, 3 lanes wide. In the right lane it tracks toward the left line about 6" closer than I would have driven for the last 60 years. In the left lane it tracks to the right lane about 6 inches closer than I would normally drive. I am constantly fighting it, I wonder if it only tracks one lane line and does not compensate for actual lane width?

 

The workshop manual does not specify that any camera calibration needs to be done if the camber, castor, or toe is adjusted.

 

Thanks for all the good information! Perhaps it is just the new tires. Today I drove a different route home and didn't feel the wheel fighting me as much. The difference between the two routes is the one route I mainly drive has grooved pavement. I'm guessing maybe the new tires with it's aggressive tread is being affected by the grooves in the pavement? That and hearing that a wheel alignment does not necessitate a camera calibration makes me think this is just attributed to the tires.

 

Motor week on PBS just had a segment on this.

 

About the truck itself or steering issues?

 

Did you get an alignment print out to compare with alignment specifications?
Should look like

Before and after adjustment angles. This will show what the alignment achieved. The castor setting has a bunch to do with the tracking How this applies to camera based lane keeping I do not know, do not have that on my 2017XL. KM

 

it was about wheel alignment and cameras that require unique equipment.

 

I didnt get an alignment sheet but I saw one in the paperwork. My dealer covered everything so I didnt think to ask for it. I think, for piece of mind, Ill have the calibration done. Its definitely worse with the different tires. Whether thats because of the the AT tires or the alignment, Im not sure.
