FSD drives differently after installing Winter Tire Package

[sammy5001]

Its never recalibrating the camera, look at the visualization, if it shows the truck in the center, and its actually on the line, then its a calibration issue. But that is never the case, the calibration is always checking and recalibrating against itsself(that’s how it calibrates to begin with) when the calibration is incorrect, you can’t enable FSD, and are required to do a new calibration. It has 9 cameras, all of them would have to be off, by the same amount for it to think it was in a place it isn’t.

I agree, I don't think it's a camera calibration issue. In my case, the visualization shows exactly where my truck is. When it's centered -- it's centered. When it's stepping on the line, the visualization shows it stepping on the line. The computer knows exactly when it's stepping on the line.

I've observed two things with my CT:

* During a turn, it always starts out good. But as the turn gets tighter and tighter, it seems to hit some limiter that prevents it from turning more. This results in understeering. You can see it in the visualization.
* When there's gusts of wind, it appears to try to turn to fight it, but with a strong enough side wind, it just can't do it.

My current hypothesis is that certain tires may result in oversteering or understeering. FSD tries to fight these over/under steering but because of the limits imposed on it, there's only so much that it can do. Rumor has it that FSD 14 is more "aggressive" -- I wonder if this version may address these issues.

I maybe have caused some confusion. I linked Chuck's video only to show how to do a DAS reset, not because his issues were similar.
In the event the DAS calibration has some values for kinematics, it might help and seemed fairly painless to try.

There is also the tire type screen under Service -> Wheels&Tires, but winter isn’t an option there.

I am at the service center at this very moment. Just went on a drive with the tech. He said whoa, it should no be like that, as we were halfway on to the shoulder!!

FSD probably just needs a calibration specific to deeper lug tires. Not a big priority right now since there are probably only a few thousand Cybertrucks with winter tires and FSD.

My model S was so good at counteracting wind, I wouldn’t even know it was windy, until I disengaged FSD, it also did better in AutoSteer than FSD, when it came to centering itself in between the lanes. The wind resistance is much worse on the CT thought, could be it.

V14 has fixed this issue for me in my cybertruck!!!!! Truck stays pretty much dead center WITH my duratracs on

Same for me, no lane centering issues with snow tires on v14.

I put on my Duratracs for the first time a little over a week ago, and so far, no issues whatsoever. No wandering, even a little better centered than before. Of course, I also got the new FSDv14 so that was the big change.

If I were experiencing wandering, I'd have the alignment checked. Make sure the tires aren't toeing out.

alignment was perfect. It was a software issue. v14 fixed it.
