The Puncture Proof Tyre Thread. Road only.

[beanzontoast]

Back in my Gators days, I stuck with (groan!) rubber solution (i.e. bike patch glue). It never seemed to stay sealed for long, but to my mind was better than nothing. Whenever I thought about using superglue, I couldn't get the two sides of the cut to stay together enough so that there wasn't a splinter of hardened superglue in the cut.

Superglue ( Cynoacrylate ) works.

You have to clean the mating faces absolutely spotless. ie, get the tyre off and dip it in boiling water, spread the split and get a fine brush in there.
Rinse in boiling water and allow to dry properly WITHOUT touching it.

Rubber solution doesn't. The back of a repair patch has a chemicaly treated surface which reacts with the vulcanising solution. The inner tube is roughed up to provide a 'key', much enlarged surface area.
The plain rubber of a split tyre won't react with the vulcalising solution.

I'm hoping with the M+ installed, this will become a distant memory!

 

[Tynan]

without sounding like Midas, when it cuts badly enough I replace

Luganos at £13 tops hardly break the bank and you get a brand new tyre

Beanz,

Even with a sheet of kevlar under the rubber, the rubber can cut-up on a unseen broken bottle.

Tynan,

When I'm 24 miles from home ( at work ) and 8 miles from the nearest bike shop, getting the tyre off at lunchtime, washing it and applying Loctite does the job until a replacement tyre can be sourced.
In fact, I have two Gatorskins at home waiting to be used, but the Loctite repair has held OK since last November's encounter with the bottle at the bus stop.

 

[jimboalee]

I had a look at the M+ 26 x 1 3/8" for my upright.

But have you seen the weight of the things? Almost 2 lb !!

Yeah, I know - but we live in hope!

 

[MajorMantra]

I agree beans - the Gatorskins are good, but they do seem to 'cut' a lot. Of course, we are all on the look out for stuff embedded in the rubber but I am collecting an awful lot of glass, flint, pedestrian etc

You're right there! (As long as it's ukelele up to banjo size max. Don't want to get lumbered with a double bass...)

BACK to the topic...

The Vectran layer in Conti's GP4000 et al does seem to work pretty well (crosses fingers, sacrifices inner tube to our lady of the broken glass).

 

[jimboalee]

I was riding home one summer evening and my attention was attracted by a glinting on the front tyre.
I stopped to see what it was.
It was an office staple that had entered the tyre tread and been deflected sideways by the Kevlar layer. It needed a pair of pliers to pull it out.

The tyres were Michelin something Kevlar. Back in 1995.

In fact, I have two Gatorskins at home waiting to be used, but the Loctite repair has held OK since last November's encounter with the bottle at the bus stop.

I managed to split the sidewall of a tyre once for about an inch, I managed to patch it up using the big patch from the repair kit and rode it for three more miles to the nearest shop, damage to a tyre so bad that you can't ride it is pretty far fetched, you can always put something between tube and tyre to protect the tube

The mean streets of London regularly bring big sharp things into violent contact with my tyres, at £13 a tyre I'm not to look after them other than picking bits out when I feel like it, I'm not going to remove them and wash them ffs, they're disposable parts

 

[amrushton]

Bontrager Racelite Hardcase. All Terrain Cycles had them for £10

 

[Aperitif]

Thanks for the replies everyone - I liked the reviews and sort of understand Tynan's disposable stance but, being old and silly, short on time etc etc I think M+ might be the way to go. Weight is not an issue - I would rather lose two kilos than struggle en route with a dirty tyre. £42 a pair at BikePlus which is 1.7p a day - for the subsequent 'commuting year' after they are fitted! (I like silly rationale...)
