I don't know for sure but I cant possibly think how you would be able to break the bead of the tire and fold the tire down enough to be able to change the sensors. I just got new tires and the sidewall of the runflat is so stiff it could easily support all my weight 235# with no rim or anything in the tire. Unfortunately I don't think it can be done
I built a device a few months ago to try to change a couple of TPMS in my Lexus IS250. It's not the easiest thing to use, but it did work fine for that car. It bolts to the floor and with some effort, it will break the bead. I bought 4 new TPMS sensors off FB Marketplace and an Autel programmer also from the same source for about $200. Local tire shops here want $95 per TPMS installed. It worked fine on the Lexus with low profile tires......unfortunately when I tried on my brothers Tahoe, it did not end well. A 4 inch tear was quickly made in the thinner sidewall. Thank goodness for roadside hazard warranty.
You can buy a similar tool at harbor freight, but I build this from leftover materials i had laying around. It just cost me a couple hours welding and cutting. It breaks down easily and stores in the corner of the garage. I'm not sure if I'll use it on the vette when it's required. DIY bead breaker

Anyone try to replace your tpms sensor at home?
Any of the YouTube methods work for runflat tires?
The sidewall on the low profile tires, whether RF or non-RF, are so stiff that it's just about impossible to DIY. Only option I can think of is the bead breaker tool from Harbor Freight, but not even sure that would work. https://www.harborfreight.com/bead-breaker-58769.html
I have not done it on the C6, but I have done it on low profile tires in the past. I have an old JC Whitney (bought 40 years ago) bead breaker like the ones posted above to break the bead, make sure and break the bead all the way around, then stuff a couple scraps of 2" x 4" wood to keep the bead away from the rim near the TPMS, then remove and replace the TPMS. Be prepared to fish the TPMS out if you drop it. Once done, remove the 2x4s and then air up the tire.
