Rob said it very well. What the chart shows as the "Red" area is actually the normal operating area for Isuzu engines. Red is normal for us, so if you are above the red on the chart you are actually in the red for an Isuzu.

Going from a 4.56 to a 5.13 is a 12.5% increase. Going from a 31" tire to a 33" tire is a 6.5% increase. Which means overall your RPM's will be 6% higher with 5.13's and 33's than with 4.56's and 31's. Now with 33's and 5.38's, your RPM's will be 11.5% higher.

Which means if you are turning 3000 RPM with the 5.13's, you would be turning 3165 RPM with the 5.38's. 165 RPM at highway speeds is not that big of a deal IMO. But once again it is not my money, so whatever you decide is best for you is what is best for you.
