Primo Grande Foam Filled Tire - 9" x 3.50-4

A: Hi Richard,

Thank you for your question!

The Primo Grande Foam Filled Tire does not take a standard pneumatic inner tune. The entire tire is filled with foam. This is a common feature for wheelchair tires and is primary used to avoid flats.

In order to ensure a proper fit, you will need to order based on the tire size, rim size and bead width. The easiest way to start is to find the numbers on the side of your current tires. We can use that information to find the correct tire for your wheel. Another option is to call the manufacturer of your wheelchair to clarify the tire size.

Thanks Richard,

Mike Benge
