Can you repair tyres?

Postby bardygrub » Thu Jan 31, 2013 8:48 am

Hi All,

Can you repair tyres?

My 400km old GP400s hit something on the road yesterday and shredded the wall.

I'd bin that.
Maybe you could patch it from the inside if it was in the middle of the tread but a cut on the wall I'd not want to patch, or trust if it was.

I've had success with those sorts of cuts using Shoe-Goo. But I always swap the tyre back to the rear, less consequences if there is a blow-out (although that's never happened)... :)

I use Shoe Goo for filling in nicks after extracting glass from tyres, but not actual penetrations!

I once patched a bad cut in a 20mm Specialized Turbo S, sometime about 1989 I'd guess. Ridden at 105-110psi, it was still very serviceable after this, I rode the whole 1991 GVBR on the bike with this tyre, and rode many more kilometres when I resurrected the bike in 2008 after a 17 year lay-off. The bike did not get ridden miles as a commuter but has done regular long distance rides of 100-200km in that time and the tyre was finally retired with a worn out tread - patch still intact inside the side-wall :wink:

Another +1 to "bin it" from me. Damaged casing is grounds for a new tyre to my way of thinking.

I've used this on sidewall cuts but suggest you put the tyre on the back.

Last time it happened (on a near-new Michelin Prorace 3) - I used a generous amunt of Shoe-Goo to create a large 'plug' from the outside. I made sure I pinched the hole open and stuffed it full of Goo plus smeared it fairly wide around the outside to give it plenty of adherence.

Then, once that dried, I put a puncture patch on the inside of the tyre over the hole - basically to 'smooth out' the Goo poking through (so it didn't abrade the tube) and also to spread any pressure from the tube over a wider area around the hole (so it didn't force its way through.

And of course, I moved the tyre to the rear wheel.

That was enough to let me use that near-new tyre until it wore right down to almost nothing.

Cheers,
Abby
