Must be the weight difference between your truck and my 4Runner.

I'd think I had some engine issues, but it runs like a champ, has compression well above the minimum and a fresh top end. Spark plugs, wires, cap, rotor, air filter, oil and filter, all with less than a thousand miles on them.

New Tire Size/ Old Tire Size x Current Gear Ratio= New ratio to maintain final drive.

So, for instance, in order for me to maintain the stock ratio when putting on 33" tires, I would divide 33 by 29(1.137931) then multiply that by the original gear ratio of 4.1 and my new gears should be 4.56 (4.6655171 to be exact, but last time I checked, they didn't make those).

31s to 33s with original gearing of 4.56 would mean new gearing of 4.88.

BTW, when you put bigger tires on your truck w/o changing the gearing, this makes your speedometer/odometer say you are going slower/shorter distances than you actually are. More circumference= further per revolution. With that being said, (without arguing the accuracy of this calculation method) if you simply take your tripometer reading divided by your # of gals, you will actually get a lower number than is accurate. Does that make sense?

I also gear'ed my truck 4.88's and 33's. I get up to 21-22mpg on the hwy in the summertime, and I can EASILY roast the rear tires whenever I want.

And the weight savings from 4runner/pickup is pretty good too

But it is VERY hilly here, I can't accell up too steep of a hill in 5th, so 4th is needed.
I regularly go up to whistler mountain
