Recently went from 315/70r/17's to 285/70r/17's and I am having a strange problem. Now when I turn left or right around a corner with my foot on the brake pedal slowing down, my traction control light comes on or the abs comes on. Steering wheel is close to centered. What is going on? Thanks.

 

How close to centered? That would be the easiest thing on your JK to check and fix. Even if it doesn't work.

 

Did you re-calibrate the speedo? That seems like the most logical issue. What the computer is being told and what is actually happening are not matching up.

 

Has to be actually centered not close.

 

It looks centered to me. Also I did recalibrate with my pro cal. Thanks

 

Yep. If it isn't exactly on center during test drive on flat surface, expect the lights during certain turns. Adjust, test drive, adjust, test drive until it is perfect.
