I believe izook.com has a tire size calculator on it that will allow you to correct speedometer error. If memory serves me, with 30" tire, your speedo will be off 12% and so will your odometer I presume. So you need to add 12% to your fuel milage for the correct figure. The easiest may is to multiply your current mpg by 1.12 and you will get your corrected mileage. However, 30" tires all very in actual diameter. Most are around 29.5".
ZuksRule is right with the hubs unlocked. We bought our '87 new and the dealer said about 25 avg then with the hubs locked you'd lose a few maybe 20-21 and then in 4wheel it would end up about 15-18. Jim
