So here i am

Whats the best wheel and tyre combo for offroad use on an 1983 M.Y soob?
A set of 13" wheels with fat rubber? (i gather from another thread that these sort of tyres are hard to come by?) Like 205/60+?
Or 14" wheels with somthing like 185/65?
Whats the maximum profile/width (on 13's if you can and 14's) that i can fit without rubbing? (im not going to cut any guards!) What do you reccomend?
Any help is greatly appreciated!
