I have a 2015 Sportster 1200C which has fat tires like the 500 Rebel. 130/16 front, 150/16 rear. The bike uses Michelin Scorcher tires, I think they are the 31’s. I really like them, excellent handling tire. Can’t speak to the longevity. I have the Scorcher 11’s on another bike(radials), and they went about 8000 miles. Probably could have gone 9000, but I decided to change them at 8. The 31’s and the 11’s are both pretty sticky tires, so I’d guess the longevity would be about the same. If I was gonna change tires on the Rebel, I’d give them a look to see if they’d work. Just another option.
