Gear Ratio??
So I have an 89 Yj 2.5 an I'm going to be upgrading my tires to 33s but I want to upgrade my gear ratio as well. I have a Dana 30 in the front and a 35 in the back. It is a daily driver for me but I will be offroading in it as well. I was thinking about going with 4.88 gears but don't want my gas mileage to go to complete crap. Sooo let me know what you guys think and prefer!

I got a 95 YJ with 33s and regeared to 4.88s and couldn't be happier. My speedo is only off by 3 mph...when I am going 60, it is actually 57. I go up hills in 4th gear at about 50 mph and I don't have the pedal through the firewall. Glad I went with the 4.88s over the 4.56s. Gas mileage wise I haven't noticed...haven't paid attention, since it isn't my daily driver, and I don't live near a 4 lane highway...all 2 lanes and 55mph.
