cut in tire--replace?

A miniscule cut in a tire allows for something similar to a
pinch to develop. If the tube so much as shows an ant's baby
finger out of the tire it gets cut off, resulting in another
flat. And you never know when, usually 12 miles into the
woods. also the cut allows free passage of a sharp small
pebble to peirce the tube again.

So im my opinion I always change the tire too. You can do
emergency repairs with a small cut but the tube is
unreliable so I would not go downhill at high let loose
speed with it still on.

I think very few people would get a new tire after every
flat. It would get kinda expensive. My old tires all have
cuts in them. Some go all the way through but most of
them don't.

I did get a cheap rubber gun and will patch larger cuts with
the hardest compound tube I can get. My greater worry is a
large cut picking up a piece of gravel or glass and not
letting it go until it punctures the tube.

Boot it--reinforce the inside of the tire with something
so the tube doesn't hernia--duct tape is the
traditionalists' choice. If it still worries you, then
make sure that the cut tire is moved to the rear if it
isn't already there--but don't rotate worn tires of course--
you said these are new so...

Wait - what's a rubber gun?? What kind of compound is in
its tube??

That's what we call around here the little 'guns' that take
various compounds of rubber and melt them sufficient to
patch items. The compounds come in a variety and I've used
them for athletic shoes and tires (mostly) and they are
shaped like a larger version of what you get in the middle
of an eraser pencil.

Is this "rubber gun" anything like a glue stick gun?
Sounds intriguing.

Sounds like what I'd call a Hot Melt Glue Gun, or just Glue
Gun. But I wasn't aware there are rubber compounds that
they can use.

Thanks for the responses. How many layers of duct tape
do you use?

Michelin Pro Race tires seem susceptible to glass cuts.
According to my records, most of the MPR's I've had to scrap
have been due to sidewall cuts. On several occasions I've
had pretty new tires suffer a cut that was not possible to
boot. On one occasion I tried several different types of
boot (duct tape, and a bike shop purchased boot), but they
failed to keep the tire from re-flatting.

If the cut is longer than about 0.25 inch (0.635 cm), it may
not be possible to boot it. At least, that's been my
experience...YMMV.

Sounds about right to me and I'd never try booting a
sidewall cut, unless it meant the difference between walking
and riding home 😉. Of course this varies tire to tire. I've
never ridden these Michelins, so I'm not familiar with the
construction, maybe it's time to look for a sturdier
tire...or perhaps they're worth the hassle?

I think they are worth the hassle. I really like how they
perform - they're light and use a fairly soft compound that
seems to hook up well in corners. They are not, however,
high mileage tires. I average around 1600 miles on them
(FWIW, I weigh 175 lbs).

I wouldn't pay full retail for them, but they're reasonably
priced at www.biketiresdirect.com .

Is there any particular reason not to use a patch for this?
I don't see that mentioned, but I've tried this and it seems
to work OK.

I don't quite follow the advice to move the tire to the
rear. Rear tires tend to get more wear, and more flats, and
are a bit harder to change when a flat occurs. Why move a
slightly questionable tire to the rear?

Because a rear flat at 20+ mph is less likely to cause
an accident.
