With an auto and 35's I'd say that 4.56's would be a perfect mix for you of on road useability and off road gearing. If you were running a manual you would need to be at 4.88 to be the same. However if you don't mind having the RPM's run a little higher on the highway then going to 4.88's will help you even more when you are down in 4LO.
