Yes. I can see how that might be helpful. I have a '98 E-150 Ford Econoline 4.6l auto with 3.55 rear.
I'm planning a few trips over the next 6 or 7 months. Mostly open road travel on the Interstate Hwy system. No towing involved.
I was thinking that if I put 32 or 33 inch tires on the rear rims it would be like having a lower rear end ratio. Maybe squeeze out a few more miles from my gallons. Does this sound feasable?

Thanks in advance,

the problem of going with a larger tire like 31's, you also have to go wider, I.E. more tire to turn and more rolling inertia, which in most cases amounts to lower mpg, not higher, during acceleration. Overall you may see a slight improvement on long hauls with constant speed, but prolly not enough to off set the price of 2 tires.
31x10.5r 15 will fit your stock rims, and will stand 1 inch taller than a 235/75r15 , 32's may require a wider rim.
