Well, they are Goodyear Marathon "special trailer" tires, 15" wheels. I
don't have the specs in front of me right this second but they are
"standard" size. I'm using the same size on the older 1969 29' Intl
Ambassador as we are on our newest 1995 34' Excella Classic.
If I get out to the garage tonight I'll look up the sidewall info and post
it here.
