Blew out out two in one trip a few years ago in the middle of the summer, on a two-lane highway in Central Texas. Was not pleasant. While in camp that trip, removed each tire and took in to a Goodyear dealer in a nearby town and had them all changed.
One important thing I should have noted. With tandem axles, if one is smart, he will break the lugs on the offending wheel(s), put your leveling boards in front or back of the good tire and roll it up on that instead of using the jack. Would have been a lot more pleasant at 100+ degrees than that lousy jack I was using at the time.
