However it is going to slow down acceleration in every gear as a drawback! (less torque multiplication factor)
I found the change from 215/50 (yes quite worn out) to 225/50 changed the "effective" final drive more then I would have figured! Also the fact that BFG under rates the diameter of their 225/50 KDW tire quite a bit!
The added traction is great though, but I could not see dropping to a Zetec gear without some major power adding. (I.E. Forced Induction! Not just a 3L!)

It was not broke; Yet I fixed it anyway.
