Oh, Im sorry to hear that @Zoe7 😣
I hope you can recover with rest, its not easy chaining a tyre using the little braces that are in the tyre change kits in cars these days... I recently had a flat that popped the tyre so I couldn't roll on it as it was completely flat and rolling on the rim through the flat. I changed my tyre place because they used to over tighten the bolts (I have bolts that screw into the wheel hub instead of nuts that screw onto the studs that come out of the hub - backwards design, and very hard to lift the tyre and hold it there with one arm while trying to locate the thread in the hub with the wheel bolts), however I swapped to Bob Jane, and asked them to reduce the rattle gun pneumatic pressure when they use it to tighten my bolts, and I would then use their torque wrench to ensure it was at 120Nm (Newton metres) for each bolt - hand tightening the final amount of tension/torque, in the recommended pattern of tightening for a 5-stud wheel, once it was off the hoist. Sometimes the staff do it for me, when it's someone I know at the workshop.
Here's a helpful article from Cars Guide on tyre changes, if its helpful for you?
I also use my body weight through my feet on the brace to undo and tighten roadside tyre change bolts/nuts, but that is a bit risky regarding falls if the brace isn't well positioned on the bolt/nut first. And I check the tension daily if I havent tightened using a torque wrench to ensure I have the right amount of tension... as a former truck driver, I have changed too many tyres of the large and very difficult to move variety, so I thought I might share here in case its useful.
I hope there is something helpful here, for the long away future of the next tyre change 🙂
I hope you can feel better very soon, and the wall work goes smoothly xx 🙂
