As tire replacement is needed, I am considering moving from 235s to 30 inch tires. The XJ is a 5 speed with 3.07 gearing. A search suggests that 31s are too big for 3.07, but I found nothing relating to 30 inch tires. I typically average between 22 and 25 mpg with 235s where most of my driving is rural -- dirt road, 55 mph secondary roads, and some in-town. For those of you who have moved to 30s, have you sacrificed mileage and 5th gear usability?
