One inexpensive 195/60 touched the inner fender. The rider fixed it with a heat gun.
About 1/8 inch clearance on the drive side of the swingarm. Rubbed the inner fender until trimmed, then about 12,000 miles without trouble.
Mounted and ridden. No long-term report yet.
Only fit after grinding a bracket and shifting the wheel. The rider advises against it.

Car sizes close to stock, on paper
These car tire sizes come within 3 percent of the stock 160/80-16 rear in overall height, by the math alone. They are not rider-tested. Width, rim fit and clearance on your bike still decide what actually works.
Stock sizes come from published fitment listings and owner forums. Check the size on your current tire or the label on your bike, then read the big questions and the mounting guide.
