Repairing rips in tires?

Took a direct hit from a piece of glass in my front S-Licks the other day. Left a nice 10 mm long
rip in the tire. Was just wondering if theres any way to glue it and keep the tire a bit longer? I
already put a nice thick tireboot of rubber in, but I think that rip is going to grow and the tire
is fairly new.

Commiserations. I had a similar thing happen to a three-week old Stelvio recently. I tried
superglue, but it seemed to be reluctant to hold for very long, and eventually I had to resort to a
new tyre following a Several of vists from the P*nct*r* Fairy. Fortunately, the last one occurred
only two minutes walk from Bikefix.

I have since tried gluing it again and leaving it to set for agesandagesandages, but I don't have
much confidence that it'll stay stuck for long at 120 psi.

Mikael,

I just scrapped a 520x25 with a stone cut. I decided to pitch it, even though a boot might work.

The cut was teensy and held at 80 psi after a road side repair. Later, when I pumped it to 100 psi,
I got 1/4 mile down the road, when "BANG": the tube bubblegumed through the hole and blew.

With my luck where the P,,ct,,re Fairy is concerned, a sacrifice is necessary, to get back on the
good side.

You may be luckier than I

I don't think there is anything that will make the tire usable for anything more than a spare. Deep
cuts longer than 5-7mm that penetrate the the belt are enough for me to DX the tire. I have had some
success with a product (available in this country) that runners use to extend the life of running
shoes. The brand name is "Shoe Goo" It is a pliable resineous kind of glue that can build up worn
soles on running shoes. I found that injecting this 'Goo' into the cut and spreading it out on the
inside and outside of the cut to form an "I" shape plug will give the tire a little longer life.

I discovered a cut on the sidewall on the rear tire on my Greenspeed just the other day. It's
close to a half-inch long, and it was puckered outward pretty badly - it's one of those
all-the-way-through cuts. I was hoping that this string of posts would suggest an easy,
fool-proof way of saving the tire, but it doesn't seem like it.

Does "superglue" glue anything but fingers? It didn't work for the tire for me either. I have in
fact never gotten mine to glue anything for very long so usually I just reach for the epoxy.

The cut is in the thread and the bit of 3 mm thick rubber some nice polish gentleman donated for
another gammy tire last year seems to do the trick so far. And my LBS still has a few spares so I
can pop down and get one if it rips totally apart.

In related news my bottom chaintube just packed it in so I got a chance to ride with the returnside
of the chain along the wheel and didn't like it. Damn thing hit the spokes on occasion so I rode
the last 8 miles in third gear. Relaxing but dull.

Sucks to have to trash a relatively new tire because of a rip, but:

New tire: $25-$60 bucks, depending.

Trip to the Emergency Room after patched tire fails during fast descent: $250 minimum.

Of course, our Danish friend may not have to shell out that kind of dough for a trip to
the hospital.

Nope, already paid via our taxes. I'll spare you folks a trip to the ER by not mentioning how much
we pay. ;-)

Anyway rip is across the thread and so far not critical but I'll keep an eye on it.

I have had some good results by making a boot out of a piece of rim tape, the type that is made with
a heavy fabric with adhesive backing, such as the "Velo brand". I had a cut in a road bike tire
(120psi) and used a piece of rim tape for a temporary fix, that was over a year ago, and am still
using it. This cut was bad enough to cause a bulge in the tire and the tube was showing through the
cut, the rim tape was strong enough to prevent the tire from bulging.

If it was a back tire, I would just watch it to see what it will do. However, it is your front tire
and that could make a mess when it blows. I would just replace it.

maybe a combo of shoe goo and tylex material as a laminate? no idea if it would work , just a
suggestion..

 

It's a rear tire, like I said it's been a year now, it's the same status as the day I put the temp
repair in. I'm going to replace it, just haven't taken the time to do it yet, to many other
priorities.

Have had some luck with "Liquid Nails" paneling adhesive. 8 months and counting on a MTB tire.
Obviously YMMV. /\/\/¨

I've used "Shoe-Goo" many times to fix a damaged tire. First, I sand down the affected area and
clean it with alcohol. Then I spread a thick film of the goo over an area a couple inches larger all
around than the cut. I quickly press a piece of fiberglass cloth into the goo, trimmed wth rounded
corners and smaller than the coated area. I rub it thoroughly with my fingers, to work as much of
the goo into the weave of the cloth as possible. Then I spread another coat of goo on top and work
it in. Then I hang the tire in a way that will make the repaired area stay straight and have a
proper shape while it hardens overnight. Sometimes, some strips of masking tape around the tire will
help it hold its form.

However, I would ride on such a repaired tire only as an emergency spare or for use in times of
severe personal poverty. I wouldn't trust it with high pressure and certainly not on a long or
fast ride.

If you need a tire for best performance and dependability, it would probably be best to chuck
this damaged one, curse the beer drinkers of the world, spread some green for a new one and
hope that your number doesn't come up again soon in the road hazards lottery.

The best uses for superglue are on joints with a very fine match between edges or surfaces and
limited flexing of the joint after repair. I have has it work very well on some kinds of repair, but
tires would be a completely inappropriate use for superglue - usually the edges of the wound are
rough and mismatched, and considerable flexibility is required after repair.

superglue works well for sealing puncture holes in tubeless mountain bike tires, haven't tried in on
a large glass cut, but would doubt it would be effective.

I cut my rear tyre on a supported ride a few weeks ago, and one of the LBS's fixed it wil the rim
tape as mentioned below, and also tode me of a couple of emergnecy repairs... a dollar bill folded
up and the wraper from a power bar (or similar) it's made of mylar apparently..

The fix enabled me to complete the ride (another 40 or so miles). A friend of mine did the dollar
bill approch (I found out after the ride) and rode the tyre out... about a year later.

I've subsquently add a roll of rim tape to the repair kit a carry.
