A tyre nicely collected part of a hinge causing a narrow cut some 20mm
long in a tyre. The cut is a nominal 45 degrees diagonal to the tyre
axis but close to the centre.

I'm presuming such a long cut would render it unrepairable?

This is a pretty new tyre for a 4x4 so does anyone know the criteria for
when a puncture is repairable?

On or off road? It wouldn't be a problem to a local mechanic in a third world country.

Very much on-road. They try stayed up for quite a long time without any
visible distortion around the hole/slit.

There are a couple of approaches to this.
The DIY hack/bodge would be to glue/wedge a few "bacon strips" into the
cut and see how it lasts (we did this many years ago on a lawn tractor
that had run over a paint scraper, it seemed to work OK. I repaired a
puncture a few weeks ago with a single bacon strip, but that was caused
by a staple and was so small I had difficulty getting the tool into the
hole.
The proper permanent approach is to pull the tyre off the rim, grind
the repair surface and apply a hot vulcanised patch to the inside or
possibly both sides. But I think it would probably have to be a fairly
valuable tyre for this to be worthwhile - it's common for construction
and agricultural tyres.

These are nominal £100 mark with very little wear. I have tyre place in
mind and shall contact them on Tuesday.

Is that because bacon is untouchable by an ever increasing population of

Beware QuickFit when I had an unrepairable puncture the branch charged
me £106 for a replacement tyre when the same tyre if ordered online was
£159! It took a lot of emails before they agreed to refund the difference.

Correction the branch charge £206!

Hmm! So they charged you £43 more after email negotiation?! :-)

I assumed that might be the case.

I'm having to scrap the tyre which after a year's inflation is now £160.
I have a spare rim so can have maintain a pair of equally (un)worm tyres
of the same make etc keeping the other as a very good spare.

This seems to be common practice with some of the chains - three prices
i) Order and pay on-line
ii) Telephone first for the price (remembering to ask if balancing,
valve* etc. and VAT is included).
iii) Just turn up.

The other con is the free safety check or free wheel alignment check.
They will always find something wrong and the repair or adjustment
charge will be high.

*Valves may not get routinely replaced these days as many have the TPMS
sensors attached.

I'd love the local tyre place (big chain) to offer me a free wheel
alignment check on my kit-car - as they have previously refused to
adjust it, when I have requested them to, as "it is not in our book and
we can only use the figures from our book". Another place nearby simply
used the figures I supplied (recommended by the owners' club and within
the range given by the kit manufacturer) and simply asked me to sign the
invoice to say that it was set to figures supplied by me.

Since then I have made my own jig for checking it myself - basically a
giant G-clamp that I can check the distance across the back and front
edges of the pair of wheels and just look for the difference in
fractions of a mm from the angle turned by the "clamping" screw.

I've used a string going around the car from the back wheels to the
front. If the wheelbase front to back an adjustment in any measurement
must be made.

I've also got one of these though I didn't pay the advertised price:

It's quicker and easier with my tool. A bit of spare steel angle that I
had to hand and a few minutes with a welder, made a simple tool that can
neatly fit over or under the car and measure wheel rim to wheel rim at
both front and rear of the wheels, at bearing height. Measuring what
would be a straight line through both bodywork and engine. The
difference is measured in mm (1.5mm per turn for the screw-thread).

For the kit car, it is even easier, as it is supposed to have 0 toe - so
I just have to make sure that the handle on the measuring screw is in
the same position on both measurements.

No need to support strings at front and back of car, just position,
turn, release, move to other side of bearing and repeat - all by myself,
without having to measure anything or even move from sitting on the
floor, in the one spot.
