That'll mean more rpm, which are going to cost you.

Smaller (lighter) wheels + taller tires is the best option.
Keeps weight down and can still increase the diameter.

Dunno what size you're looking at ?

My engineer friend replaced the struts and springs on all 4 corners and raised his ride hight by nearly 2 inches on his 1999 J-body. He says the hit to fuel economy is with in the standard tank to tank deviation and saw no clear hit to fuel economy. The car is driven at least 75% highway driven.
So unless you spend a lot of time above 90mph I don't buy into the ride hight thing.
I went from P235/75R15 tires on my suburban to 31x10.5/R15 load range C tires that were about 15 pounds heavier apeice and nearly 2 inches taller. I expected my fuel milage to go down. It didn't fuel milage went up slightly.

Tire weight isn't going to effect fuel economy on the highway. Each inch of ride hight you go up increases drag by something like 2% or less.

Taller and wider tires have higher load indexing and have lower rolling resistance than a smaller tire of the same make.
By going to load range C tires on my suburban I picked up 2200lb of load, the tires went from being nearly 90% loaded when the suburban was empty to closer to 50% empty.
Also when you put non LT or lettered load (C, D, E ect.) ranged tire on a truck or SUV its recommended you derate their load rating by 11%.

On a car 1 size taller could give you 100 to 400 pounds of load capacity.

If I ever build an electric vehicle its getting 15 inch load range C or LT tires because its going to be heavy.
