The Primo 14"x3" (3.00-8) pneumatic tire with C248G Powertrax tread for mobility scooters is a very popular tire for scooters and power chairs with 8" rims. Like other pneumatic tires, this requires a 3.00-8 inner tube. Because many of our customers prefer using pneumatic tires as they offer a smoother ride than solid or foam-filled tires, we offer this tire with the option of including a matching inner tube. You can select just the tire, or with a tube that uses an angled valve stem.
