WK2 Electric LTD slip rear axel

[Texascherokee]

My rear axel ratio according to build sheet is 3.09 ratio, I want to change it to 3.45 ratio, will this put me in limp mode because the wheel sensor doesn't match transmission output speed? With the 3.09 ratio the 5.7 Hemi at 60MPH the engine bogs down at 1200 RPM in 8th gear. I usually put into paddle mode and downshift to 7th or 6th gear to get RPM up. I think Mopar put this high rear axel ratio in for fuel economy . Thought from any experts here? Former EcoDiesel Owner

Texas, I like My 3.09 in My Summit. It never dropped to 1200RPMs in 8th, What Tire size?
