Wheels for 1961 Overlander
One thing that I might add to your thought process as you consider tire size. While the 205 series tire may have the weight carrying capacity necessary, if your coach is anything like my '64 Overlander (or my friends' '60 Overlander) the last thing you want is any reduction in ride height. I went with the 225 series Good Year Marathons, and have not had any clearance issues. I had feared that there might be clearance issues so I took my coach to the Good Year dealer and had him do the preliminary measurements and recommend the "tallest" ST rated tire from the Good Year line that would fit my coach - - his recommendation was the 225 - - by allowing him to make the recommendation it became his responsibility if the tires came in and then wouldn't fit the wheelwell (I made known my concern about the wheelwell dimensions during our preliminary discussions). My current set of 225 series Marathons have been on the coach for five seasons, and have performed flawlessly - - they are slated for replacement in 2005 as the Argosy will be my primary coach for traveling during the upcoming season.
Good luck with your decision!
