Howardval: Holy cow, that's not good! And it looks like you went above and beyond everything to unseat that tire. Totally agree with you that this is an untenable situation to continue on; however, I do have to ask if you have tried to remove that tire from its rim since the tire was unseated by your local LBS?
No. I used talcum powder to put everything back together. Would like to wait a couple of weeks before attempting to take it off again. Wanted it to seal with some time before retrying.
Looking at that ring nail, I believe the larger plug made by DynaPlug to tube bicycle tubeless tires would seal that nail hole. The company states it will seal a hole up to 1/4 inch.
I'm confident it could be fixed with a plug/patch on a tubeless tire. But I highly doubt it would self seal with the sealant!
For myself, I had my air compressor to inflate my tires in order to seat the tire to the rim, but other than that, there was no mess at all involved. As you know, there are now floor air pumps with the capability to inflate a tubeless tire & seat the rim. I honestly wish I had gone tubeless when I first bought the Haibike; it'd have spared me a ton of grief on the roads and trails I ride on.
From what I understand, the mess with the fluid is when you have to take it apart. Would be much easier in a garage (which I don't have). And on the road, I guess you can always use a tube in an emergency. I also have too many tubes in my stock, so I need to use 'em up!
