I'm on my second set, 255/85/16 on 70 series wheels, and running them on my FJ60. Last week did this in the Ozarks in southern MO SSS 2021 - Mark Twain National Forest Oct 22-24 - https://forum.ih8mud.com/threads/sss-2021-mark-twain-national-forest-oct-22-24.1256394/ and the Yokohamas worked...
I think not. To run these would require suspension alteration such as a spring-over, new wheels plus the tires resulting in an overall less-drivable FJ60. IOW a pile of cash to deal with a situation that I seldom encounter and it's negotiable with good recovery gear.

A few photos of the Geolanders in mud and these are new tires. First a mix of red clay and sand mud in Alabama, rolled through this in 2WD, no issue.
Geolanders met their match with heavy clay...
