1981 fj60 mpg??

i'm looking at getting a 1981 fj60 and wondering what the miles per gallon on it would be. also wondering the biggest tire i can put on without trimming, rubbing, or having to put any kind of lift on it. any help is appreciated. thanks!!

HI

I have an '87 and get between 12 and 16mpg with 33x9.5 witha 3" lift

I had 31's before the lift without any problems.

FJ60 is a gass guzler. Most get between 11-13 mpg.
