Sir,
Does this tire fit storm 3 ? So it is a split rim? Is it hard to replace? Thank you for your time and effort.
Yes, this tire is compatible with the Invacare models listed under the "Compatibility" section of this item page. The 3G Storm Series appears to have a split rim, I'd recommend checking the back side of the wheel assembly on your unit just to be sure - there should be some screws holding the rim together if it is a split rim. Replacing the tire is a relatively straight forward process, and it shouldn't be too difficult. If you have any trouble, please don't hesitate to give us a call at 1-800-798-0325 and we'd be happy to see if we can walk you through installation.
