How do I decide if these five tires are holed too close to the sidewall?
Yesterday, for practice in dismounting, patching, and remounting, I patched
these 5 tires above, which a friend and I had lying around.
For the purpose of this thread, we can ignore the tread wear since the
question is being asked about how to decide when a nail hole is too close
to the sidewall.
I guess the first question is *WHY* we can't patch next to the sidewall.
Is it that the patch won't hold? Why?
Is it that the patch will flex too much?
Or is it that the belts are damaged and they will break?
Thank you for the information as some were on the last tread groove (see
below how we patched it with a home-made plug patch.
Thank you for that advice because I wasn't sure at all how close you can
get to the sidewall for it to fail the patch test.
We patched this alloy-wheel 55-series tire where a flat-on-both-sides tiny
bolt (with no sharp edges whatsoever) had wedged itself into the last
groove, and eventually punctured the tire.
Here you see the tiny (now headless) bolt next to the puncture hole:
To properly patch that hole, we reamed the hole with this hand tool:
Using that hand tool, we probed the hole slant (it went in straight):
Then we grabbed this second hand tool & slobbered glue on the plug:
This is the plug sticking up on the outside of the 55-series tire:
To cut off the protruding plug, we failed trying the diagonal cutter:
We also failed with the flush dikes because the plug was too rubbery:
We ended up slicing it off with a utility knife but we learned how to slice
the plug off more neatly when we cut off the plug protruding on the inside:
The dremel tool metal blade cut off the plug flush with the inside wall:
Then we buffed with a wire wheel, where we learned that it would be much
nicer to have a "ball" shaped wire wheel because of the angles involved in
buffing away the outside rubber to expose the virgin rubber to the
Here is the buffed result before applying the patch over the plug:
After applying vulcanizing glue, we stitched down the patch:
Where this is what the final patch looked like:
Any advice you can provide will be helpful as the whole point was to learn
by doing, where already I'd do it differently the next time (e.g., I'd use
the dremel tool on both the inside and outside and I would get a roundish
wire brush that fit the inside of a tire better.

That's a good question which I don't know how to answer.
Thinking about it, I guess it's just that I hate to not be able to do
something that I *should* be able to do at home.
We should all be able to:
a. Mount and dismount a tire at home
b. Patch a tire at home
c. Balance a wheel at home
I patched all five tires, and learned a bunch about what tools would be
better (e.g., a roundish wire brush would be a dream come true to have).
Here I found that breaking the bottom bead on an alloy wheel 55-series tire
was tremendously easier than it was on the 75-series SUV steel-wheel tires
(but you notice how I positioned the purpose-built HF bead-breaking tool
with a board on one end and the HF tire changer on the other end):
Then I learned to mark the position of the valve since we'd normally be
re-using these tires and we would want the balance to be the same as it was
before (at least as a starting point):
Breaking the top bead was so easy that it doesn't need explanation:
Likewise, levering off the top bead from the alloy wheel was easy peasy:
Levering off the bottom bead from the alloy wheel was also very easy:
Then, it was time to plug and patch the hole, which, in this case, was made
by a bolt that was NOT sharp!
The bolt may have wedged into the groove and slowly punctured the tire:
Any advice you can provide (that is intended to be helpful) is welcome
because I always want to learn (but advice saying have it done at a shop is
not going to be helpful).
If I were the only driver on the planet, and never drove closer than 500 me

level of detail incurred so far.
But, I drive on crowded roads with other drivers who have lives of their ow

And the occasional fluids-tanker or propane tanker with flammable and explo

So, here we are on the Pennsylvania Turnpike (Speed Limit: 70). And my left

The reason men here can *fix* things, is the same reason that men can build
airplanes and rockets and fly around the earth and to the moon.
The simple reason is that men who can "do stuff" pay attention to *detail*.
Specifically, without paying attention to detail, nobody can build or fix
Specifically, detail is required to *understand* how things work, where
those who can't handle such detail are doomed in many endeavors in life.
Worse, men (like you appear to be) who can't handle detail, are doomed to
make completely incorrect conclusions, since all you see is the top layer
of everything which is complex.
Since you only see the top layer, you see nothing of the detail underneath,
dooming you to ascribe causes to things which are just not the case.
In fact, you're forever doomed to make incorrect conclusions, simply
because you (apparently) lack the ability to handle detail (which is
required for comprehensive thought processes).
Um. OK. So do we all.
While you don't seem to be able to handle detail, you do seem to handle
fear very well.
The only reason you added that otherwise meaningless statement above was to
increase the fear, since *emotion* is what you feel given you are
apparently unable to comprehend detail.
What you're doing with that statement above is what all politicians do when
they want the masses to be mislead. You are working on pure emotion, hoping
your audience is, like you, unable to comprehend your lack of detail.
There should be an analysis upcoming of what caused the tire to "shatter".
In that analysis, I would expect detail from most men, but not from you.
From you, all I expect is upcoming emotion.
Your complete and utter lack of detail makes your entire argument moot.
What exactly caused your left-front tire to "shatter"?
You don't have a clue.
Therefore, all you have is emotion.
Again, you'd make a great politician because you lack detail and yet, you
ply emotion instead.
What I find amazing is that I have been responding to you, in line, where I
have ascribed the ethics and tactics of a politician to YOU.
I provide far too much detail and truth to be a politician.
That you use the word "blather" when detail was provided shows *exactly*
how your mind works.
Engineering detail is "blather" to you.
Hence, your only input is purely emotional.
Thank you for stating for yourself, exactly what I have surmised from your
very words, which is that you are incapable of handling detail.
You should recognize this inability to handle detail for what it is, which
is a disability I don't have. I have *plenty* of other disabilities mind
you (e.g., I go far too deeply into detail for my own good), so it is
cathartic for you to recognize that most of your technical conclusions will
be wrong, since you are operating on sheer emotion.
As long as you know your limitations, you won't be a danger to society.
I know mine - which is that I spend far too much time and energy on things
that are merely interesting in their myriad details.
This newsgroup seems to have *plenty* of political posts (for some odd
reason), so you should be happy here, as am I as there are few, but
existent engineering style posts also.
You are incapable of making that assessment because you lack the details
that I have which is critical in assessing whether a mechanic actually
performs the job correctly.
All you're operating on is intuitive emotion.
I'm pretty sure you're a Myers-Briggs highly intuitive person.
That's fine - but you're also a highly Judgmental person, which, put
together, makes all your *decisions* dangerous (but that's a topic for
Again, you operate on pure intuitive emotion, sans any valid facts.
That means your opinions are based on absolutely nothing concrete.
At best, you'll be 50% correct, although you'll be convinced that you are
100% correct since you are the one assessing yourself.
You do realize that you're operating, like a girl, on pure emotion, right?
This is a thread about how to properly repair a tire.
This newsgroup is apropos for such a discussion.
Your discussion is really apropos for a newsgroup titled more akin to
men.who.wear.ladies.pink.panties or some such rot. :)
Exactly. Detail scares you.
You really may be one who is better off in the psychology groups since you
seem to be *afraid* of detail, such that anyone who delves into detail
scares you so much that you actually fall to the depths of depravity to
stoop so low as to warn others that people may ask for detail on the
automobile and home and science repair newsgroups.
Your use of "it" shows your depravity indeed.
Therefore I discount you out of hand, for utter lack of detail.
You're the same kind of Myers-Briggs person who is highly intuitive and
highly judgemental, who actually thinks cell phones cause accidents
(without a shred of detailed reliable proof backing up your claims).

I understand you completely.
You're not telling me anything I don't already know.
I think I'm telling you something you don't already seem to know though.
Everyone, including me, would *intuitively* say the same thing.
I can't disagree with the intuition.
I have intuition myself.
The difference between me and you is that I don't *trust* my intuition as
much as you seem to trust your intuition (and certainly, neither of us
trusts our intuition as much as pfjw trusts his intuition).
So what do I do that is different from you?
I check my facts.
I simply intuit (like you do); but I double check the facts.
Most people don't.
They can't handle the detail involved.
My intuition says that a cat stuck in a tree won't come down without the
fire department or some other rescue effort. But it's just not true when
you look at the facts.
My intuition says that a mountain lion in the woods would attack a human it
sees, but the facts show extremely few attacks. So intuition is trumped by
facts (for the most part, since some attacks do occur but not as many as
you would intuit).
My intuition says that the sun revolves around the earth, and if someone
didn't tell me otherwise, I'd still believe my intuition. But facts always

Does he supply a single fact to support his safety claims?
Can anything he says be believed?
Does *he* firmly believe everything he says?
Almost certainly he does.
Highly intuitive highly judgmental people are dangerous that way, if they
ever have power. They make decisions that they think are correct but which
are not supported by any facts.
I can show you an arbitrary non-real-world study that proves almost
anything that I want to prove, simply by limiting the variables in the
study, so, as you already know, we'd have to look at each study you claim
to prove your point to see what its limitations are.
If I set my mind to it, I can probably prove, for example, that cancer is
caused by almost anything I want to prove is carcinogenic.
However, the double check of the study is the real world.
In the real world, nobody on this planet has ever been able to prove any
correlation in the accident statistics overall that can be atributd to
cellphone use while driving.
In fact, since the accident rate is steadily decreasing in all states, with
or without enforcement of cellphone laws, the opposite may actually be true
(but I won't go that far).
In summary, you and I (and everyone else) would *intuitively* feel that
cellphones are an added distraction which should cause added accidents; but
the facts show otherwise.
Why is that?
Most morons posit a mysterious counteracting force, which is possible, but
they never provide any proof of this mysterious force, so, it's not
What's most likely, IMHO, is the simple model that says distractions while
driving abound. There are literally thousands of distractions in any daily
drive. Thousands upon thousands.
So, my hypothesis, which fits the model that accidents are just not
occurring due to cellphone use, is that adding one more distraction to an
already long list of distractions only adversely affects the bottom
percentiles of drivers - who - the fact seem to show - would have
distracted driving accidents no matter what.
While that model isn't proven by me, it fits the facts.
Your model doesn't fit the facts.
How do you reconcile that your model does not fit the facts?
(Hint: That will take intelligence & attention to detail, but not pure
intuitive judgemental emotion.)
I can't do that and have no desire to do so. In the past 20 years I can
think of three tires needing repair. My car came with roadside service
so I called the number and a guy comes and changes the tire for me. In
two cases, the tire was not repairable in the third, i drove it to a shop.

Plus I like learning.
Wow. I seem to have at least one a year, and sometimes more (lately).

My wife has AAA. It makes her feel safe.
Truth is, if she has a problem, she calls me.
If I need the car towed home, where I have better tools, I call AAA.
So, we're in agreement. AAA is wonderful for towing.
I'm sure they're great for running out of gas.
And, perhaps for opening locked car doors (if possible nowadays).
I don't know any guy who would call someone else for something as simple as
changing a tire though. It almost takes longer to make the call to AAA than
it does to change the tire yourself. Even if it didn't, you'll be waiting
for the truck to arrive far longer than it takes to change the tire.
How long does it take you to change a tire anyway?
Yup. All the tires I fixed were not repairable due to the lack of tread.
Had the owners driven on the tires, the belts would be showing on the
inside, and hence they would not have been repairable.
Had the holes been at the edge of the steel belts, again, they would not
have been repairable.
Had the holes been larger than a quarter inch, they would not have been
However, except for treadwear, the tires I worked on were repairable, which
was the main question after all.
We already showed that out here, the cheapest shop is about $20 to $25 per
tire, so, that's $80 to $100 for a mount and balance. I'm sure a tire
repair is along the same lines of cost.
I've raised my tool estimate from $200 to $250 because I'm adding the cost
of the carbide reamer, the cone buffer, and an assortment of weights, in
addition to the separate stand-alone bead breaker.
So, using round easy numbers, at $25 per tire, it will take 10 tires to
recoup the investment, which we can double to 20 tires for a safe margin on
At an average of 4 tires every two years plus one flat every two years, for
a two-car family, that's a replacement or repair of 5 tires a year (which
is pretty much fitting my use model).
So it will take two to four years to recoup the investment in tools.
I have lots of tools that recouped their cost in the first use, and others
which took five or more years, so, that's just about in the range of
expected return on investment.

I know I am.
I drive about 22,000 miles a year and the worst case is to add some air
a couple of times. Present car has 25,000 miles and for the first time
I had to put air in one when the TPM went of when it was 7 degrees one
Ah, it pretty much has. Many cars have a can of air now.
It was dark, about 35 degrees and raining. Took the guy about a half
hout to show up and do the change. Meantime I shopped in Home Depot.
The first time was a dozen years ago. I ran over a body bolt and it
made a big hole in the sidewall. Car was about two months old. I took
the other car to work. Dealer came over, took the tire off and mounted
a new one, put it back. No idea how long it took them but I lost no
time. Had to pay for the tire, of course.
When I was a teenager driving a '53 Merc with either used tire or
recaps, I changed many tires. Found a better way.
In 44 years I've had 5 tires go flat "on the road" 3 of those on one
trip due to faulty valve stems (on the PT Cruiser on PEI), 1 due to a
cinder in the black hills of the Dakotas at -40 on the '69 dart, and
one on a sunday afternoon on the '63 Valiant (with no bumpers so I had
to jack it by the trunk lid.) I've had a few go flat on the driveway
that could be aired up and driven to the shop.
I've never had one damaged to the point it was not repairable due to
running flat. Both of the ones that failed flat on the road were down
low enough on tread that I ended up replacing the full set shortly
I'm a former auto mechanic and I won't "patch" a tire in the field
unless I have to.
I patched a lot as a kid on the farm (tube type on wagons) and bikes,
lawn tractors etc., and a LOT in the shop as a mechanic.

Most of my flats have been slow leaks which gave me time to air them up and

I almost never drive highway nowadays, so, my 15K miles is on side roads,
where there is some construction. I average something like 1 flat a year,
sometimes more, sometimes less.
Anyway, they wouldn't put spares in cars if flats didn't happen.
I did drive with a very low tire for about a mile. The tire was filled with
fluffy rubber shavings, and the belts inside were showing. So it was
stupid, in hindsight, to run them when they were flat.
Depends on what you call the field.

Wow. A apark plug. I wonder if that's what I ran over?
One day, decades ago, when I was just an obnoxious kid, I was following a
truck at night on a crowded New York highway and I made the mistake of
pissing him off (I was young and stupid). I probably beeped him or flipped
him the bird but I don't remember what I did nor what he did to cause the
altercation. He may have been innocent and he is just circumstantial, but
while I was following him, my tire suddenly blew.
All I remember was hearing a loud POW and my tire was flat instantly.
There was a gash in the tire tread, as I recall, and nothing else visible.
As if a knife had been stuck in the tire. I changed to the spare, and
remember thinking, "never piss off truckers" (and I never did again, since
truckers are not your friend).
A day or two later, when the tire is replaced, there is an actual deep mark
in the alloy wheels on the *inside* of the rim directly across from where
that gash was, but no object. To this day, I don't know what suddenly
flattened that tire; but whatever it was, it was big.
Whatever flattened that tire was long enough to go inside the tire and
touch the inside of the rim which is a few inches, but it then came out. It
was like as if a railroad spike had been run over.
Not saying the trucker did anything to cause your
flat that night, but: Not all truckers like their jobs.
Many are under pressures not self-imposed, but
by their employers or customers, to get product
to stores where you and I can buy it. And sometimes
their driving habits show it: Speeding, tail-gating
other drivers, frequent lane changes, frequent
use of the horns, etc.
Best just to give them their room. Remember:
this is not Star Wars - they are not "Imperial Star
Destroyers" and we are not Luke in his X-wing,
or Han Solo in the Falcon, zooming by them in
outer space and taunting them. LOL
