Don't expect t use 5th much at all, 4th only on the highway, and likely nothing more than 3rd for the mountains, unless you run the rpm's near redline(if you have a tach) before shifting.
If you are on the aggressive side of the driving spectrum, you will likely hate it, if not, you can put up with it until you swap the gears.
What is the current size tire you are running now?
