Tire Replacement: if we are talking of an Argosy trailer, I highly recommend the  Goodyear Marathon--size + TS which stands for Trailer Service (I think. If not TS it is some other combintion; the T referring to "Trailer". This tire is made for trailers and is NOT to be used on cars (says so on the sidewall) They are highly resistant to sun and ozone deterioration. They may not have the tread life of some other tires (e.g. General, Cooper) but if you are not going to be piling up the thousands of miles, this tire is vastly better. I have used them since they were  first introduced on the market.
