First set of Michelin XLT A/S (Sam’s equivalent of the Defender) P265/65-17 on the wife’s 4Runner went 78k.
Current set is over 70k but probably could be replaced.

Have Defender LTX M/S LT275/70-18 on the Tundra. It sees mild off-road use including rocks. Not much mud.

I’m a fan.

For your use they can’t be beat IMO.
