| Dec 1, 2021 at 9:03 | comment | added | Chris H | @Criggie IIRC the rim is 19mm and the tyres (this and the other one that went the same way on the same rim) 32. So that should be fine by Sheldon's chart. If I've muddled my rims then these could be 21mm which would be a little wide for the tyres. When I fitted a new tyre I had a slightly rough spot but probably caused by stopping cautiously with a totally flat tyre, and I don't know if it was near the failure. 600 grit wet/dry paper buffed that out in a few seconds. | |
| Dec 1, 2021 at 1:11 | comment | added | Criggie♦ | I have a 26 " MTB that wears tyres just inside the bead like this. the tyres are 2" and the rim is probably too narrow, and I tend to run a higher pressure than I should... so the rim fretts on the sidewall. Might be worth confirming the rim width is okay for the tyre width ? | |

| Nov 30, 2021 at 9:04 | comment | added | Chris H | @DavidW that matches the one time I successfully improvised. On Saturday we were 50km into a planned 200km ride, so even directly home would have been a reasonable distance, with some tricky descents in the conditions | |
| Nov 30, 2021 at 9:03 | comment | added | Chris H | @WeiwenNg the tube holding it in place is a nice theory, and might even work when it's not right next to the bead | |
| Nov 30, 2021 at 9:02 | comment | added | Chris H | @Michael this one (Conti Gator Hardshell) and the previous (Schwalbe Marathon Supreme) were both 32mm and about 80psi. Same wheel, I think 19mm or possibly 21mm rim width, came with 35mm tyres as stock. Another was overpressure - a 38mm winter tyre where I normally run 28mm and a stuck gauge on my pump | |
| Nov 30, 2021 at 7:26 | comment | added | Michael | What did you do to that poor tyre sidewall? Are you maybe riding at too low pressure or with very narrow rims? I’ve never heard of a tyre failing that way (and it looks like a Conti GP which should be good quality). | |

| Nov 30, 2021 at 0:27 | comment | added | MaplePanda | Anecdote: the rear tire on my hardtail is held together with Flex tape. There’s a nice hole on the side that’s too big to seal. Possibly, a stronger adhesive than what’s currently available is necessary. | |
| Nov 29, 2021 at 23:06 | comment | added | Weiwen Ng | As far as I know, punctures large enough to need a boot would defeat any tubeless sealant. So, maybe the answer is that you need some sort of tire boot in general, but that can be duct tape. However, I was under the impression that the tube should hold the boot in place, at least at road and gravel pressures. NB: I've never got into a situation where I needed one, so I'm speaking from what I've heard. | |
| Nov 29, 2021 at 23:01 | comment | added | jwh20 | I can only recall using a boot one time. I ran over a piece of steel strapping that punched through the tire and tube. But the damage was more of a line than a hole. I'm sure the tube would have bulged out of the tire so I added a boot. It held until I got it home which was 10 miles or so. As small and light as they are, I can't see any reason not to carry one just in case. | |
| Nov 29, 2021 at 22:34 | comment | added | DavidW | Anecdata: I've used a boot myself a couple of times (once I had an actual stick-on patch, the other time I improvised) and have helped a couple of other riders. The problem mostly (3/4) was something had cut partly through the sidewall, severing a few of the threads and causing the sidewall to bulge. A boot helped spread the pressure out, reducing the bulge and preventing a concentration of pressure that might cause the sidewall to unzip. The tyres were all immediately replaced, but the boots got us home. | |
