Don't fear the gear.

How can you accurately figure MPGs with larger tires, wouldn't the odometer be off?

Marginally

Top off tank, get on the highway and use GPS to figure exact distance to a gas station a good ways away. Drive there, top it off again to figure exact fuel consumption. You know have accurate distance and the amount of fuel used to get there.

On a related topic, I'm torn between 4.56 and 4.88 for the Burban. 4th in my 80e isn't as tall as it is in a 60e. 4.88 would put me around 2650 rpm at 80 mph which is generally my cruising speed on the highway, if not higher.

That's a lot of work just to figure mpg though a much easier solution is to download an app that tracks miles traveled that way you don't have to make a special trip

That would work too.

After running mine a while, My 4.10s are plenty deep for me with new 35x12.50x17 federal couragia mt's. That being said, I have a manual. I wouldn want the gears any higher, because i tow a fair bit (big ski boat). It maintains 5th gear on the highway over the steep hills around here. If it was an auto, I would probably run 4.56's. My speedo is off alot. 4.56s should put your speedo/odo close.
