No, the 2011 Harley Davidson Sportster 48 model originally came equipped with tube-type tires. Tube-type tires require an inner tube to hold the air, while tubeless tires do not require an inner tube and have a special seal that prevents air leakage. If you're considering changing the tires on your motorcycle, it's always a good idea to consult the owner's manual or contact a Harley Davidson dealer to confirm the tire specifications for your specific model.
