I'm Cursed. My CBR that tried to kill me in December felt decidedly odd when I got it out of the garage last night - steering eratically - so I nursed it to the petrol station at the bottom of my hill and checked the front tyre pressure. Supposed to be 36psi - was 10psi. Jeeeez. Didn't look that underinflated. So found a large tack sticking out of the tyre - prized it out - hissssss - stuffed it back in again. Balls. In the garage they sold a 6 quid SOS Tyre Repair aerosol. After much faffing about with the brake discs making manoeuvering the aerosol and garage inflator hose a nightmare, and foam flying everywhere turning the scene into a tragic comedy snowstorm, I wrestled the tyre back up to pressure and got home. Testing the pressure again today, it seems the repair has held. But does anyone have any experience of using this foam stuff? How long will the repair last, and has my use of this foam stuff meant that my tyre shop won't be able to do a proper repair later?
