Toyo Open Country AT IIs too flexy?

Wondering if any of you out there with the new Open Country AT IIs are experiencing pretty flexy sidewalls. I'm running the following:

P265/75R16

If you see my thread here regarding a weird wobble when coming to a stop, it seems one culprit could possibly just be the tires flexing. I took it to the local 4Wheel Parts where I purchased, had them drive with me, take a look at my setup, and they seemed to think the same things, although they didn't necessarily think it meant anything was wrong. I know I'm probably nitpicking here but wanted to get other people's experience to see if its just something I have to get used to, or if there is something that can be done to eliminate the issue.

 

I have the same tires and don't have any problems with them so far. If you 4wheel you might want to get an alignment and see if that helps.

 

which sidewall rating did you go with? P or LT?

 

P265/70R17

 

I see some of us are more literate than others...touche


Since it is the P rating, that is my guess as to the flexing sidewall. They won't be as thick as the LT.
