Since using tyre inserts I’ve had this problem in my mind , you have damaged a tyre too badly for it to seal up it needs to be tubed ,
problem is your left with a very bulky and messy insert covered in tubeless fluid . So best carry some disposable gloves and a bin bag .
I also figured if I’ve damaged my tyre beyond it sealing up its likely to have a fair size hole or rip in the casing . I use Rat bite inserts which fill the tyre void rather than the rim void so I thought perhaps a smaller tube to fill the rim void would work .
Well I’ve recently tried the idea , my fluid was dried up and it was time to change tyres ,so I simply broke the bead one side removed the tubeless valve and stuffed in a 700c roadie tube ,the normal pressure I ride with felt the same as when tubeless so off I went on a days ride to try it out .
It worked well , I had no hassle with it despite the tiny roadie tube being too thin for the size of the void , i really could not tell the difference with the tube fitted . I deliberately gave it a bit of a hard ride over some rocks etc that could often result in a puncture without inserts .
I’ve since sourced a better sized tube to carry as a spare 650b x 35mm seems about right if you can find one .
Another plus is I only need to carry half the size of tube as a spare .
I guess the same method could work with other rim void inserts and a tyre gaiter and valve extension .
There also a new insert I saw in the bike shop yesterday called a Tannus. Which uses a tube in this way , it looked very good and didn’t seem heavy like some I’ve seen and only about £25 so there an option to those who aren’t liking tubeless , be good to hear some feedback on the tannus quality looked high
