Urethane Pyramid Wheelchair Tire with Easier to Install Design Fitment NotesSolid wheelchair tires are purposely made smaller than the wheelchair rim so once they are installed, they will not come off. The main complaint most customers have while installing a solid tire is the amount of force needed to stretch it onto a wheelchair rim. Uninstalled, this tire is roughly 19-21.5 in diameter making it the largest uninstalled tire we currently sell with the pyramid design. It also has stretchier cords inside the tire. Being larger uninstalled with the stretchier cords means there is less stretching involved to install the tire onto the wheelchair rim. A solid wheelchair tire installation tool is still required, but the effort needed to turn the wheel on the tool will be much less. This tire can be used on Drive, Medine, I-nva-care, Everest & Jennings (E&J), Breezy, or any other wheelchair rim that calls for a 24 x 1 inch pyramid shaped tire.Installation Note:Installing these tires onto a wheelchair rim can be very challenging without the proper tools. This is because the tire itself is smaller than the wheelchair rim and needs to be stretched onto the rim. If you do not have the ability or the tools to properly install these tires, it is advisable to seek professional help. You cannot install this tire by hand!
