Okay so this time around I went with a bigger tire. Now have 275/65/R18 instead of 265/60/R18. Now when I'm driving down the road (normally its a rougher road when this happens) the traction control deactivates and the ABS light comes on. Whenever I turn it off it goes away and doesn't come back on until I'm driving again. I changed the tire size w/ my superchips programmer but it still does the same thing. Has anybody else run into the same problem when upgrading to a bigger tire size? If so how did you fix it? Oh and its a 2007 F-150 2wd w/5.4.

Thanks in advance,
