I'm fully prepared with Velox tubeless repair kit, mushroom plugs, and weird shaped needles and fishing line to fix sidewall gashes.
However, after a few moments of contemplation, imagining a high speed blowout and crash, or the less severe but really annoying unfixable tyre during a group ride or multi-day event, I normally find myself playing it safe and throwing £45 at a new tyre.
This is a 15mm gash that resulted in a loud bang, an instant deflation and a comedy sideways slide in front of a group of walkers. It's got a temporary patch and a tube in there and it's bulging slightly, I'm pretty sure that's a goner and trying to stitch it will just weaken it further.
I'm not really looking for anyone to change my mind on this particular tyre, but whilst I mushroom plug a less severe hole (5mm sidewall) which is probably as bad as I'd be happy to repair, I'm open to any opinions on what permanent repairs you have completed and would trust. (trailside anything goes of course)
I'd have a shot at super gluing, stitching and patching from the inside with Connect Blue cement

(I have found small tubes of the cement available)
Thanks feed, this is for the larger gash? Has anyone else done this and survived?
It's a 40c gravel tyre so the split is most of the sidewall.
I've done a sidewall slash that sort of size, 10-15mm through the carcass of the tyre, 20-25mm of rubber on the outside gone, rode over the edge of a smashed clay rooftile.
Dental floss to stitch it up, tyre boot on the inside, normal patch on the outside, plenty of cement all over. Wouldn't have done it except for it literally being the first ride of a £60 tyre.
Rode it for another year or two on and off until i rode over another roof tile (on the same stretch of trail) and put a 40-50 mm slash through the tread...
