I wouldn't worry too much about the aspect ratio , the width will probably be the limiting factor for fitting it on your bike .
Different brands of tyre , although ostensibly the same size ,when compared side by side will show a considerable difference in ACTUAL size .
So you'll have to try out a close match and see if it will fit under the fender/between the fork legs/within the swingarm .
I'm running some dual sport tyres on a classic road bike and they are not only a lot cheaper than pattern originals they also work great .
