Aloha! I am a Caregiver for a friend with a Permobil M3 Corpus. All of a sudden, BOTH center wheels (one each side) apparently began losing air at the same time. The sound they make while in motion and slowing down more and more is pretty bad, and at this rate, the chair will be completely immobile by tomorrow.

I searched YouTube, ChatGPT and Perplexity AI and found SOME answers on how to solve this problem, except for the biggest issue:

There are no visible valve stems on either tire!

Does this mean power tools and tire disassembly will be required?!

That is out of my scope of knowledge, unfortunately.

Will a service call be required? Something else?

Please help, with your sage advice.

Many thanks.
