Bought an Fed auction forestry '96 XJ 4.0. 5 spd a year ago after many years of lusting (in my heart only). All stock. 2 great surprises: On replacing all the gear oil found the limited slip in rear diff( shows how little I know) and am also getting up to near 25mpg hiway only ,with 235-75Rs ( at 28.9 about 1 inch larger dia. than stock). This at 4,200ft + elevation and prob no speedo adjust either. After extensive searching this forum this may sound incredible. One thing I found here, the MPGs are all over the map! The point is-a front shock is clunking badly and the ride makes a buck board buggy look plush. Enough reason to spend big bucks on this DD! Looking at mild lift quality suspension and going to 30-31' tires BUT: Priorities are 1. Nice ride on bad washboard and rutted dirt roads AND pavement! 2. Maintaining good MPG 3. Some towing, 4. A little more clearance, flex would be nice if not too costly (10% say) on MPG. I realize that the variables are infinite but any help apprreciated. I am now looking at "soft" OME kit and 30" max tires. All options on the table like aluminum rims. performance upgrades . Suggestions ?
Any one here that can say the impact of going from 28-29 to 30 " tire on MPG? Lastly- in theory larger tire should cover more ground per RPM and increase mpg except as heavier weight requires more engine work/gas than distance gained produces. Can steel to alum wheels save mpg with a bigger tire if not too fat? Any help appreciated TIA All
