Don't know, haven't tried it. An advantage of the booting material is
that the patches are much bigger than tube patches so they can cover a
much bigger tire cut than would be the case with the tube patches. As I
look at the construction of the patches the boot patch is thicker, has
material woven through it and "appears" more rugged.

I have ordered some of this material. I'm also carrying some pieces of the
old inner tube for hte same purpose.

Have you replaced it yet?

Actually, chances are the tire's still servicable. It might not
even need to be booted.

Here's my unfounded guesswork about dealing with damaged tires:

when it comes to the decision to boot or not, it may pay to first
determine whether the puncture is a simple hole (as might be
caused by a nail) or a gash. A nail-hole tends to just spread the
fibres in the tire, and the hole is fairly localized and benign.
A _gash_ on the other hand, cuts the fibres and creates a rupture
that may spread and expose other adjacent fibres to subsequent
damage. A boot holds the gash together from the inside, but it
doesn't really provide much exterior protection from further damage.
You can try to mend the gash on the exterior too, with contact
cement or tire repair compound, but still, the original integrity
of the tire is as lost as virginity.

I like to always align the valve stem with the
inflation spec on the tire. It comes in handy.

I have replaced it, but I kept the old tire, just in case.

Viewed from the inside, the hole is very small....perhaps 1 mm. It looks
much larger from the exterior. I could easily put a piece of that tire
booting material in there that gds mentioned (I bought some).

I think it's too small to try to mend, but boot material on the inside seems
reasonable.

Good idea. Never thought of that.

Roger,

I would have booted the tire to get home. Cut pieces feom a
FedEx waterproof envelope work well.

With a puncture this bad I'd replace the tire ASAP. After
all, do you really want to be decending Saluda Grade with an
uncertain tire? Maybe relegate the old tire (booted) to a
utility bike that doesn't go far from home.

BTW, we're starting to get some good rides here in Western
North Carolina beyond the Assault on Mt Mitchell. Check it
out.

199 Mike

Actually, I tried to boot the tire. However, the damn valve stem broke on
the new tube. Since I was only a mile away from my car, I just walked back
to it.

I did replace it. I still have to old tire, though I'm not sure if I'll get
a utility bike soon (bike 2 is going to be a recumbent).

You sound as if you live close to Greenville. I imagine the riding is just
lovely up there.

I hate breaking Presta valves. It always happens at the worst
possible time. The Topeak Mountain Morph is a good remedy for
that since it works like a floor pump but much smaller. I
haven't broken or bent any valve stems since I got the Morph.

I live in Swain County (Bryson City/Cherokee). It's not a
full calendar yet but here are three late year rides that are
pretty much in my back yard.

Tour de Tuck (mid Aug)
http://www.tourdetuck.com/html/ride_maps.html
Route Profile
http://www.motionmakersbikes.com/html/tour_de_tuck.html

This ride follows the Blue Ridge Parkway up to Water Rock Knob
and Richland Balsam.


Tour of Franklin (late Oct)
http://www.smokymtnbikes.com/

Not much on the web about this one but it climbs to a place
called Standing Indian, then Burningtown (near Cowee, an
ancient Middle Cherokee Town site), then out towards
Cullasaja.

Nantahala Nightmare (early Nov)
http://www.noc.com/events_tournany.html

Very well supported ride. The Wayah Bald climb is the
"nightmare" part. Last year it was warm and we still had lots
of color. This year it didn't really warm up till afternoon.
