I am not to sure if i had a standard rear rim on one of my old Honda 750's but i ran a 140 michelin, i think it was a A or M 48 {remember them?} and i rode the wheels of that bike with no adverse effects on handling. I also had a GPX 750 Kawasaki race bike with the 16 inch front wheel, it was bloody fast and i had a metzeler comp k race compound rear 130, reversed on the front and it stuck to the road like a train on tracks. So there are some tires that work outside the norm. I will also add that there was a lot of time went into getting that bike to handle like it did and heaps of people told us that it would never work........it did.
