Fitment Notes:
The 4.00-8 Knobby Foam Filled Wheelchair Tire is a known replacement for certain wheelchairs from Pride Mobility including the Jazzy 1170, Jazzy 1170 XL, and the Quantum 1650. Make sure your wheelchair has the 4.00-8 tire size option before ordering. Pride part number TIRSOLI1021. This tire used to have a raised lip in foam above the tire bead. This tire does not have the lip but will work as the replacement.

Foam filled wheelchair tires and foam filled scooter tires provide added peace of mind knowing you won't ever get a flat tire and you won't ever have to fill the tire with air. This added peace of mind requires your wheelchair or scooter to have a two piece wheel (also called a split rim) to be able to install them. Since a foam filled tire is basically a pneumatic tire filled with foam during the manufacturing process, tire sizing is the same. However the bead width of the split rim can vary. This is because there was never standard (split rim) bead width sizing adopted in the wheelchair/scooter industry. As a result you can have several tires of the same size with different bead widths and only one of them will properly fit your split rim. If the bead width of the tire you purchase is too narrow for your split rim, there will not be enough compression between the two halves of your split rim against the tire causing the tire to rotate separately. If the bead width is too wide, you will never get the two halves of the split rim and the tire screwed back together. Taking the time to measure bead width will ensure you purchase the right foam filled tire and save you from an installation headache and the hassle of sending them back.
