Mike, what does she have the PPE set to for tire size, 35"?

 

[MMLMM]

She has it set to 34" (what I measured with a tape)

I told her to try a bigger tire see if that helps, but it didn't We'll try a smaller tire.

tried 34", 35" 36" and 37" those no work.

For that tire, try 33 and see if it works. The 35" tires are around that in actual diameter. You can get the actual by marking the tire with chalk, rolling the truck back until it makes 1 revolution and divide by pie and it will give you the actual diameter of the tire. The 37's on my old truck measured 34.7" so I set it to 34.5 and it worked w/o setting off the ABS light.
