I just purchased two 10x3 foam filled tires for my wife's pronto m50 power wheelchair and I realized that I need to replace the tab washers. Where can I purchase them?
It looks like those locking tab washers are available as a special-order item. The washers are sold in a pair for $31.99 and the part number is Q76-8543. Sadly, we do not have the locking tab washers listed on our website so orders for them must be placed over the phone at 1-800-798-0325.
