Tyre repairs.

Someone's just told me it's dangerous to repair bike tyres and that
tyre dealers won't do it anymore.

Is there any evidence at all that bike tyres can't be repaired safely?

I've had bike tyres repaired in the past [1] so my gut feeling is this
is just an urban myth put about by tyre firms who want to sell tyres
rather than working hard at putting a patch on for a tenner.

Anyone point me towards definitive answer?

[1] Only on rears but that's my superstition, not based on any fact
based logic.

 

Not true, AFAIAA, although it could be true of *some* tyre dealers.

Not AFAICT.

I had a rear tyre plugged a few months back after I found a nail in it.
The bike passed it's MOT a few days later.

Well, if an MOT tester will pass it, I guess it's OK.

 

See above.

 

Then there would seem to be no point in me reading your response then!
Other that to laugh at your attempt to consturct a case without
actually knowing any facts....

 

The question is, do you want to die?

 

I can provide evidence that a well constructed repair[1] in the centre of a
rear Michelin Pilot Sport on a GSXR750Y can withstand repeated use at speeds
in excess of an indicated 160mph....

But my understanding is that there is some sort of advice out there
somewhere to do with repairs to Z rated tyres. Can't remember if its a
British Standard or just a manufacturer's recommendation but it's something
along the lines of "It's OK if it's in the centre of the tread and not over
'x'mm wide and if it's not within another 'x'mm of another repair. If it's
within 'x'mm of the edge of the tyre, too big or the new hole is by an old
repair it shouldn't be done"

As for other rated tyres, I assume it's OK to repair as much as you want.

[1] Tyre off, glass removed from tyre, hole bored out slightly and a rubber
covered metal plug with a massive flat 'head' (like a 5cm wide round bit of
thin rubber that the plug itsself was part of - if that could get through
the hole in the tyre, it'd have to be cut in half) pushed through from the
inside after liberal application of some sort of glue/vulcanising solution

 

Superglue - you know it makes sense.

I bet that "someone" has a link to a tyre emporium.

Not as far as I know. I've had two punctures (both within 500 miles of
fitting the tyres) which I plugged myself and then rode on for the life of
the tyre.

I'd say so.

And if they don't like it, they can always go and buy a Nissan Micra.

 

It's all bollocks, mate. Of course, it's up to an individual
retailer/dealer/repairer to do it or not, but it's often accompanied by
bullshit, as is so much else in the tyre world.

 

Yeah, I've got absolutely no problem if a tyre place wants to say
"Sorry sir we don't mend tyres - we can only charge a tenner for it and
our monkey can fit 2 car tyres in the time it takes so it's just not
worth our time.". That's just their choice - bringing safety into it is
just out of order though.

Reading Ted Simon's Jupiters Travels ATM and his tyres seem to have
been more patch than tyre half the time. ;-)

Thanks to all for the replies.Esp the better ones (you know who you
are.)

 

Heh.

But yes, blowouts, if they ever really happened, are firmly a thing of
the past, with modern steel-belted tyre constructions. Even at pretty
high speeds, a flat tyre doesn't need to cause any great drama. I got
a puncture (probably at a petrol station) some years back on the way
back from viewing the total eclipse, and didn't really notice it until
I got to about 120mph, at which point the bike felt a bit funny. I
didn't immediately realise what it was, so slowed down and accelerated
a couple more times before pulling over and discovering a completely
flat rear.

The exception being tubed tyres.

See that word 'modern' up there^? The one would seem to preclude the
other.

Err - big trailies with spoked wheels & supermotos, not to mention
trail/enduro bikes.

Yes, I know they still use old-fashioned tubed tyres, but that makes
them not modern, see?

Anyhoo, Champ's post already specified he was only talking about
tubeless ones.

I should've said 'tyres with tubes', rather than 'tubed tyres'. Big
trailies & no doubt some supermotos use tubeless tyres on tubeless
rims, but tubeless rims with spoke holes, hence have a tube. They tend
to deflate far more rapidly than the same tyre without a tube on a
'sealed' rim.

I was too, I just didn't phrase it very well.

No, any trailie that needs a tubed tyre was designed to be used off-road
and isn't just a fashion statement.

If you seriously expect us to believe that...

Oh, **** it, I really can't be bothered.
