Thanks for the reminder on rim width - I'm asuming they're 5" as I search thru the specs available on places like tire rack. 225's favor a 6"-7.5" rim and 205's get me to 5.5". The next problem becomes tire diameter. If I recall, the original 750X15's were nearly 29" and a 205 series is only 27.1" Don't want to hear any screaming @ 50MPH
