This tire can be used with split rims - if the rims on your scooter or power chair do not split, you would either need a replacement wheel assembly or possibly a pneumatic tire. If you'd like to find out what kind of rims your scooter or power chair has, please give us a call at 1-800-798-0325 or email us at contact@monsterscooterparts.com to provide your unit's serial number.
