When to change the tire

Dear NG,

I have repaired tiretubes many times, but it took me lots
of years to realize that I am always doing it wrongly.
Whenever puting the patched tube back I always you a
screwdriver to lever the tire and force the last part of
the tire inside. This I believe always pinches or punctures
a hole through the tube... no wonder sometimes I wonder why
in the world the tire is again punctured when I just
repaired it a few hours ago.

Lately, I realized that there is actually a thing called a
bike tire lever. I have never tried it, but I will this
time. But I am already almost sick of putting the tire tube
out and then back in. I want to make sure that this time
when I put the tube in, I can really ride the bike for some
months before it will be punctured again. So to make sure I
want to ask for some help here.

Because of my abuse in tire repair, the tire itself
developed a slit (when I pry it with the screw driver
sometimes it slips and rubs through the rim of the tire
causing it to wear). I wonder now if I have to change the
tire itself. I earlier bought a tube, then when I put it
back (before learning about putting those tire levers) I
attempted to do everything by finger (so I wont damage the
tube like before, coz I realize that the screw driver will
not help me) after checking that the tire is clean and has
no stone or sharp thing in it. The last part I had to do a
little with the screw driver but I made really sure that I
will not puncture the tube (then I suddenly discovered
these tire levers in our workshop.. too late!). But then I
realize one thing... the tube is for 28" tire but it was
like 2 inch bigger than the tire size... is this normal? I
mean should the tube diameter be bigger than the tire?..
the shopkeeper didnt even ask me what size.. he just looked
at my tire and at once gave me the tube. On my original
tube is written 35/47-622/635 .. I am just guessing that
the first numbers correspond to the diameter and the last
to the pressure (I am now living in Germany and the
standards may be different here). .. so my question
is.. is the 28" tube the right one for this tire? I just
find it wierd that the tube is a few inches bigger than
the tire.

Well anyway.. so when I put this new tube in the tire and
pumped it (I forced the extra inch of the tube inside
too!), the tire bulged out of the slit that was in my tire.
Then I was muttering to myself "Oh.. maybe I should buy a
new tire too". But I thought that maybe I leave this pumped
tire for a day and rest. The next day, the tube was
punctured! .. so I am guessing now that (as I was careful
with the screw driver) this could be either because of the
slit in my tire or because maybe that the tube is bigger
... I don't know yet and I dont want to yet spend money for
the tire until I know exactly what I should do (I have been
riding this bike for 3 years without changing the tube or
tire and have travelled around 5400km already).

Sorry for the long post and next time I hope I wont trouble
you with such trifles.

Sincerely, Jose Capco

To start with try buying extra thick thorn resistant tubes
they are less problematic. Secondly you should inflate the
tube slightly inside the tire before rolling the last bead
over the rim. this will ensure that the tube is not buckling
anywhere. Deflate the tube and work the bead over the rim
with your fingers, it will help if the bead at the bottom of
the wheel is temporarily pulled deep into the center of the
rim. Check that you are not pinching the tube between the
tire bead and the wheel rim with whatever tool you are using
to lever over the last bit.

Ok great. But what about the tire with the slit? should I
keep using it? The tube bulges out of the slit when I pump
it and I am afraid it will pinch it (or it can easily have
contact with the asphalt road and just get punctured by mere
abrasion).

Sincerely, Jose Capco

PS: How can I know if the tube is an "extra thick thorn
resitant tube"? And how much more will it cost compared
to just a normal tube.

Get a new tire. A tube should never protrude like
that. The tube is not designed to come in direct
contact with the road!

Thorn-resistant tubes are advertised as such. You need to
use tire levers very carefully when putting the tube/tire
assembly on the rim. See

You need to either 'boot' the slit or throw out the tire.
You can put duct tape over the slit. But this is best seen
as temporary.

If it was me, I'd call the whole thing a learning experience
and start over. Get new tubes and tires. Use the slit tire
for practicing getting the tube and tire on.

I am not sure that thorn-proof tires would be of help since
you are puncturing in installation, not riding. Ask at the
bike shop what others use in your area. From what you write,
there are some basic mistakes that you are making. With just
a little more practice and attention, this whole thing will
be behind you soon and you can get back to riding!

Bike tyre tubes aren't strong enough to hold the 60psi
upwards you pump them up to unless they're contained within
a tyre. I'd say it's almost certainly gone because there's a
slit in the tyre. As for getting tyres on and off, at a push
I use the handles of tablespoons, as they at least have
blunt edges. Some tyres are a lot easier to get on and off
than others too - I can easily get Schwalbe City Jets on and
off my 26" MTB wheels by hand, with no tools.

search and read: DIY Tire removal, here in bike tech. i have
a specialized thorn proof tube and itsa good spare.
Nashbar's sealf sealers are excllent and patchable.almost
unpuncturable with a slime liner and conti tt tires. tires
are like beer. try a new brand. keep a couple on hand as
spares sparte no expense. buy full carcass tires. beyond
comparison.save your butt !!

You should be able to install a tire w/o any tools. If you
cannot, get a different tire/rim combination. With practice,
many tires can be removed w/o tools either.

I surely need to use the wrench to remove the tire off the
bike 😉 You probably meant it for the bikes that have easy
removable tire (forgot the name of it).

_ Not really, bike tire levers make it much easier, but you
can usually get the tire off by hand if the tube is flat.
You kind of grab the whole tire and roll it off. It's a
handy skill to have for when you forgot the levers. Every
time you take the tire on/off it gets a bit easier.

_ The fewer pointy tools you get near tires and tubes
the better, even with plastic levers it's possible to
pinch the tube.

There is one tool that you can use to help INSTALL tires. It is called a tire jack and it looks like this:

My wife has arthritis and lacks the hand strength to install a tire, so she carries one. It works for her wheel / tire combination. Frankly though, I do not think it is a well-made tool and I would not be surprised if it failed during hard use on very tight tires. By the way, I can get her tire on her rim fairly easily with no tools. That’s the key; if you have normal hand strength you can mount most tires without using tools. So, I second the suggestion by previous posters that you read how to install tires and practice a few times. Here is a link to the FAQ area with instructions on how to mount a tire (tyre as misspelled by our friends across the Atlantic.)

If you have a good local bike shop and you bring in your wheel, they should help you find a tire that fits and suits your riding and $$ needs.

Good luck.
