I have 3 questions for those that either installed the Rubicon wheels and tires or kept the Sahara wheels & installed larger 33 in tires.

1. Did your gas mileage go down at freeway speeds? If so, how much?
2. How did this effect the ride at freeway speeds? Is it more bouncy?
3. How did this effect your speedometer? I was reading is would drop about 5% or around 3 mph at 65 mph.

I did the same upgrade and can say:
1) I average 18 now down from 20.5-21
2) I wouldn’t say bouncy. Floaty maybe?
3) @ 65 I’m rolling at 67.44

I haven't done this so I can't answer your questions about gas, but the speed variance would be -2% too slow (bigger), meaning if your speedometer reads 100km/hr, your actual speed is 102. (so 60/61 mph?)

Mileage went down for sure, 1-2mpg depending on how I drive.

Ride feels the same as my sahara AT tires. KO2s are quiet as well, did not notice any increase in noise. Even used a DB meter before and after.

Speedo was definitely off, got a tazer to correct it.
