That will drop the 60mph RPM from 1950 to about 1550. The nice part about the tires is that they are a normal type tread pattern ie not for a 4 wheel drive type. You might also think about the 06 Gertrag being so new that nobody makes a "splitter" for it yet. They might but then again they might not. The tires are the way I'm going to go.
