The Primo gray 9x3.50-4" pneumatic power wheelchair or scooter tire with the C203 Grande Knobby tread has a PSI rating of 50. It fits many mobility models and is typically used as the rear tire for mobility scooters or the drive tire for power chairs. This fine Primo tire features non-marking gray rubber.
Because many of our mobility 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 a matching inner tube. You can select the tire alone, or with an inner tube that has an angled valve stem which makes the job of inflating the tube much less frustrating.
