Wheelchair Fitment Notes
Known to fit many power wheelchairs from Invacare, Pride Mobility (Jazzy, Quantum, Jet), Quckie, Permobil and others. To confirm the size, look on the existing tire you wish to replace and note the size numbers printed on the sidewall. It will be expressed either as 8 x 2" or 200 x 50 mm, or both. Also verify that your tire is pneumatic by looking for the valve stem. If you are changing from a foam filled or solid urethane to a pneumatic tire, make sure your existing rim has a hole for the valve stem to come out. If you need the foam filled version of this tire, it can be found on this page. 

8 x 2 in. (200 x 50) Knobby Wheelchair / Scooter Tire Purchase Notes
This is a pneumatic tire and requires an inner tube. Choose to add an inner tube with a schrader valve bent at 90 degrees or bent at 45 degrees when ordering (a schrader valve is the standard bicycle / car tire type valve). Use caution when ordering as each valve stem was designed for their respective wheel. It is best practice to replace the inner tube when replacing a tire since inner tubes can exhibit wear and fatigue especially at the seams with prolonged use.
