 Have
a Flat Tyre? Is It Fixable?
The “repairable area” of a tyre is designated as that
where a repair can be carried out to British Standards
(currently BS AU 159f).
Because a tyre curves away from the middle of where the
tyre rolls on the road, only the centre area is
repairable. Sidewalls are not repairable.
The repairable area is defined as a percentage of the
tyre’s “nominal” section width and thus varies by the
size of the tyre. The repairable area is based on the
centre line, eg. 82mm means 41mm on either side of the
centre line of the tyre.
Using this handy REPAIRABLE AREA TREAD GAUGE, you can
quickly find out if a puncture in your tyre is likely to
be repairable.
Follow the printing instructions so that it is the right
size, cut it out, read the tyre width off its sidewall,
then put the centre line of the gauge in the middle of
the tyre where the puncture is. If the puncture falls
between the markings for that size tyre, it is probably
repairable.
(Note that the tyre may not be repairable if the hole
is larger than 3mm or there is other internal damage to
the tyre.)
