from 33s to 32's for mileage,ride,maneuverability?

Significant other wants a change for ride quality and less height. 2012 jku with Goodyear Duratrac (33) 285/70/17 tires. Thinking of going down one size to (32) 265/70/17. The 33s are about 11 inches wide and load range "D". The 32s are about 10 inches wide and load range "C". Think changing will make a difference in ride and or gas mileage?

Or you can stay with a 33" Duratrac along with a 15" alloy wheel.
lighter than both and you will save some money.

The 33" is around 53 lbs
The 32" is around 50 lbs

Stock 17" wheel @ 25 lbs if you are running them? = 75lbs and 78 lbs

33x15 is @ 49lbs
15" alloy @ 20 lbs = 70 lbs for the win.

Keep your 33" and you drop some weight for the honey = you both win

not a bad thought..i believe the 285/70/17 is 53 lbs. The 265/70/17 is 44 lbs according to tirerack. My wheels are mamba mr1's-not sure of the weight but they are a rubicon clone with better backspacing. If i stay with the mambas it looks like i could save 9 lbs per wheel by switching the tires...
