Wheelchair rim coating

In the world of manual wheelchairs and quadriplegics, there's an upgrade you can buy that offers plastic coating of your wheelchair rims. Since my current manual wheelchair was purchased from ebay, the rims never had plastic coating. Although the plastic coating worked for me on my custom made chairs, it didn't protect my hand enough even in gloves when it hit the side of the wheel. I've tried everything from tape to using strips of rubber-like material from bicycle tubes or inner car tire tubes. Yesterday I decided to try wrapping plastic coated stereo speaker wire around the rim because it has the same tacky plastic "feel" but also provides more protection for my hand .

So far it's working well. I'm not sure if it will increase my pushing time, but at least my arm and hand don't "hurt" as much (spasms). So far I haven't made much progress in increasing my push time. I'm trying different gloves and adaptations though and will keep trying. As you can see in the video below, the red duct tape is to keep the ends on- we ran out of wire but there's enough on there for me to see if it works.
