Title: Flat tyre (again)
Post by: nairb on February 25, 2021, 10:22:44 PM

So at a lowish speed The rear kicked out and I stopped within 50 meters.  Lucky really.  And there it was, a flat rear tyre.  Within an hour I was on the back of a pickup and taken home.  All very civilized.

Heres a pic of the offending nail, or screw .

Its a tyre with a tube.
So in times gone past all I have done is replaced the inner tube with a new one.  But I have wondered if I should also have the tyre itself repaired also.  I have gotten old and the doubts are creeping in. I always thought a new inner tube was all thats needed.

You can use a patch on inside of tyre carcase. Cleaned and rough sanded,  then coat with rubber glue and let dry to tacky. Finally apply a big 3 inch diameter car patch.

I’ve always just changed the tube, that’s what’s keeping the air in.

You only repair tyres if tubeless, if casing damaged i would not repair a bike tyre

I agree I would just fit a new tube - a vulcanised patch as per tubeless tyres would just make the hole even bigger for no benefit.

Out of general interest I always replace tubeless tyres if I get a puncture - just not worth the risk.

I used to repair tubes with patches when I was a penniless student, I think going racing cured me of that habit - punctured tubes now go straight in the bin, or get cut up to make big rubber bands.

Yup I used to do the same many years ago.  Now old age and a few more pennies has changed all that. 

Here is a pic of the old inner tube.  Fair old patch needed to fix it.  All from a small screw and about 50 mph.

Thanks to all.  New inner fitted.

I'll have proper repairs done on tubeless tyres...but that requires tyre removal. I use a temporary plug system to get me home, then have a pro do any repairs. There are strict guidelines on what can/can't be repaired, and how many repairs a tyre can endure.

Tubes....I bin and replace.
