I have no real world experience on tire size, so take my advice with a grain of salt. I have a note I keep about all the tire sizes people have talked about for the rides that I consider the perfect stance. Stance is an art though, everyone sees it differently and we all have the one that speaks to us.
Rear tire: 275 x 45 x 20 or 295/40/20 or 245/50/20 are in my notes. They are all 4.5 to 6" tire wall and around 30" diameter.
