What's the Biggest Rear Tire I can Put on My VT600?

You can fit up to a 180 motorcycle tire on the stock VT600 rear wheel but doing do makes the rear tire bulge outward like a steamboat willie cartoon inner tube. If you remove the fender and subframe there are a number of car tires that will fit the rear wheel as well but you will be sacrificing cornering performance as car tires are squared and not rounded like a motorcycle. They are not meant to be leaned in a corner beyond a few degrees, whereas a motorcycle tire is designed with cornering and leaning in mind.
