I started out with the recreational tires and just switched to the 27" 589's from Essex. To do this I installed a lift kit. The stock recreational tire took me most anywhere I wanted to go on my North Georgia property. The were great, but I just wanted the look of a lift kit and bigger tires. Recreational tires will be a huge improvement over what you have.
P.S. My recreational tires are in my garage doing nothing if your looking for a good used set with only 10 hours on them.
