I would check all that too but his question was regarding ball joints.
If ANY tires exhibit cupping in the wear pattern there is a problem. There is nothing about "mud" tires that makes them cup when any other tire won't. Sorry, but cupping is avoidable with a front end that is in good condition unless you are running tires that are just too big for the suspension to handle.
