You can help your overall gearing a little bit by installing taller tires. I run 235/85R-16's on my GMC;the diameter is about 31 inches,compared to the 6.00-16 stockers at 29.5-30 inches. Not a huge difference,but if you need to replace tires anyway,you can benefit from a taller tire in road speed/rpms/mileage,also using a more common size can prove to be less expensive and easier to replace if one should be damaged on a weekend in the middle of nowhere. (not that you'd ever venture out "there" on a weekend...)
