Tire Pressure

the net!) for my 1974 Superbeetle.
Anyhow, I am going to get them mounted/etc. The "recommended tire
pressure" listed on the glove compartment door says Front - 18 psi and Rear
29 psi. This seems too low to me, especially in the front tires.
Just wondering what pressures everyone else is running in a stock size tire?

On my 74 super I usually run 35psi all around. I probably have the
fronts a little over-inflated, but I have never noted any abnormal wear
so I just leave it at 35.
I think(I could be mistaken) that the pressures listed on the glovebox
door are for bias-ply tires. All I've ever run is radial tires.

remember!
Most Detroit iron has a fairly even weight distribution pattern, squaring
the car's weight between the front and rear. Beetles only have a third of
the curb weight riding on the front tires. Overinflating the fronts has the
effect of changing your 165/15s into 95/16s -- not enough weight to maintain
full footprint contact with the road.
This concept will be painfully obvious if you live anywhere with wind. You
think Chicago is the windy city? Try Amarillo TX. Last time I put new tires
on my '74 Super, I specifically asked them to inflate to 18psi/29psi. They
didn't, putting in 32psi all the way 'round. I hit the freeway and grabbed
the next exit as a relatively calm15mph crosswind made the car undriveable.

Follow your Owner's Manual to the letter!
I've read too many warnings about how you should never inflate your tires to
a higher pressure than what VW says, ESPECIALLY THE FRONT TIRES!!! It's
DANGEROUS!!! You've been WARNED...TWICE.

GEEEEZ!!! You're running at 35psi all the way around??? Are you
suicidal???
You're tires are probably rated at a maximum of 35psi. That's fine if
you're just going to leave it parked in the garage or in the shade.
You put yourself in the car and the pressure goes up. You drive for more
than a couple of minutes and the pressure goes up more. You're probably
driving around with close to 38psi in tires rated at 35psi.
Where in the world did you get the idea that this was an OK thing to do???
Why are you intentionally ignoring the safety ratings of your tires and the
car manufacturers recommendations???

Calm down, dude!!! Next step is for your post to be in ALL CAPS!!!
When you use multiple !!!!!!!s and ?????s you come off as frantic
and/or annoying!!! NOW EXCUSE ME WHILE I GO PUMP MY TIRES UP TO 40
PSI ALL AROUND!!!
ps- You misspelled "your."
Think about it... "you're" = "you are"
"You are tires are probably rated at....."
Question: Does that make sense?

Ok, Ok! I get it! :-)
I got them back from the auto place, and of course, they all had 32 psi in
them. I deflated the fronts to 18, and the backs to 29.

don't have anymore) Radial tires have always required more air pressure
than the same size bias ply tire. 18 psi in a radial tire would be dangerously
low. Radial tires are not supposed to have a bulge in the sidewall when you
look at them from the front or back like a lot of people seem to think.
On the other hand max pressure(35psi) for a radial tire that size would be a
bit too much unless you were carrying a ton of extra weight. You'll probably
find that mid twenties in the front works well.

Glove compartment in my 74 super sez 18/29 for bias and radial. I was just
wondering if these values were right or not. Probably wouldn't hurt to have
mid 20's pressures. But it would probably drive like a tractor any higher.

dude calm down..its obvious you are no tire tech so maybe read your sidewall
sometime...the max psi is listed as a cold temp....this pressure is set with
a tollerance for an increase in pressure due to heat....it is not uncommon
to gain up to 5-6 psi in summer weather on the interstate, and the tire
manufacturers know it.....so don't have a stroke, your point is not only
wrong, but basically pointless....(BTW "put yourself in the car the pressure
goes up" is incorrect too...the max weight is also what the max pressure is
designed for...sheesh...)

So Joey, are you saying the tire manufacturer knows more about the air
pressure I should have in my tires than the car manufacturer knows? Hardly!
My point is 35psi is a lot of pressure over the recommended front tire
pressure on the car. Are you saying this is OK? Because it's not. It's
flat out dangerous. It's almost double the recommended pressure. It's
unsafe. It's WRONG!
So don't tell me my point is wrong.
Dan Smith
Lynn, the pressures you posted are right. Mike is making up nonsense.
Dan Smith
Oh, and the max pressure isn't listed as a cold temp, it's listed as a max
pressure. Max means max.
The normal car manufacturer's tire pressure recommendation is the cold
inflation pressure you're thinking of.
Yes, while driving it's not uncommon for the tire to gain pressure in the
summer weather or in cold weather either. And that was my point. If
someone is foolish enough to air up their tires to the maximum then they
have no leeway for normal pressure increases due to load and friction.
You also said, ""put yourself in the car the pressure
goes up" is incorrect ".
Who are you trying to BS? Of course the tire pressure goes up as the load
increases. You're talking nonsense.
Since you don't think tire pressure goes up as the load goes up you
definitely don't know what you're talking about.
If I air up my tires to the car manufacturer's recommended pressures and
then I put 400 pounds of people in the car obviously the tire pressure goes
up.

The sticker is correct. You could add a couple of pounds to each,
especially if the car is heavily loaded, but don't inflate it the same
as your Chevy. The reason the front tires get so little pressure is
that they have so little weight on them.

(AAA) ) that before a long journey, to put a couple of extra pounds in
your tyres. When they warm up, they soften and need more air.
As for loading up your car, 'my' thoughts were, a given volume of air in
a given space, give a constant pressure. For it to go up 'much' when
you load the car, you would have to see a serious flat spot (less space)
on the bottom of the tyre.
I havent looked recently, but I thought the MAX pressure was like 135psi
or something way up there ?
Just my thoughts

Air is a gas, which when heated, expands.
On race cars, tire pressures are sometimes critical. You put a certain
pressure in the tires before the race,
and when you immediately measure the tire pressure during the first
seconds of pitstop, you will find that the tire pressures have increased
by 50% easily.
Granted, in that environment the race slicks also get much hotter than
you'd ever see your street tires get...

...................Correct! And if the front tires are larger than the std.
165's, they should have less pressure, not more. My '77 has 185/65-15's on
the front and I've been running 16 psi for about 10,000 miles now. These
tires are wearing evenly and handle superbly even when cornering and braking
hard. With no front bumper, There is only about 425 lbs. load on each front
tire which is way way below the load rating of these tires. A tire's
cross-section shape is determined by the load and the pressure working to
counteract the other and less load always requires less pressure to maintain
the optimal shape that maximises the contact patch on the pavement while not
sacrificing the structural integrity of the tire. Formula 1 racing cars use
less than 25 psi on the front tires I read somewhere because they have large
profiles and only 200 lbs. load per front tire at rest and still only about
800 lbs. load per tire from the downforce generated by the wings & spoilers
that are used to increase traction at 200 mph! The worst aspect of this
'theory' that the front tires on a bug should be inflated to the twenty or
thirty psi range is that the tread's grip during braking and cornering goes
way down. I've done a lot of 'seat of the pants' experimenting with this
question over the years and I drive like a maniac sometimes. This goes
beyond everyone's right to their own opinion for me because I've seen
through direct experience that overinflated front tires on a bug are a
direct cause for loss of control at high speeds when cornering and braking.
When the road is wet, this loss of tire grip from overinflated tires is even
worse.
Tom Nakashima
It was overwhelming for me when I first saw the listed tire pressure for my
'66 bug. I had to question the settings also, when I was used to inflating
the tires on my other vehicles at 32 psi. I'm putting in 20 psi front, and
28 psi rear in my Bug. My car handles better and rides a lot smoother at
these tire pressures, however I'm not a racer and never intended to drive
the VW fast.
Rob and Dave's VW website have experimented with tire pressures, I also got
to speak with Rob by phone not only on tires but other related VW matters as
well. I really like Rob for his expertise and honesty on VW's. Since he's
done most of the research, I'll trust his recommendations.

*before* you try to "call someone out" you should study up....i was

there are two ways to increase pressure...to add it(through more air or
heat ) or to make the space smaller....you will not resize your tires by
adding weight...you only displace air in the tire from one area to another
when it is loaded down....so to quote you "you definitely don't know what

your point was wrong...exactly what i responded to was wrong....couldn't get

of tires sometime you may be enlightened....

I'm not ignoring anything. I have seen tires rated for a maximum of
35psi in the past, but I do not presently have any on any of my
vehicles. Of the 20 tires I presently own, all say 44psi maximum.
I will try running a lower pressure in the front and run a mileage
check and see what the result is. After my recent carb overhaul I am
measuring out at 24.5 miles per gallon. That seems a little low, but
one possible explanation is that the supers weigh more than the
standard if I am not mistaken. I would imagine my mileage will drop
slightly if I run a lower pressure in the front.

True. The pressure inside the balloon lowers as the atmospheric pressures
lowers, and the ballooon ruptures because it expands beyond its elasticity
(elasticity is lost mostly due to stretching but also in part by the low
temperature of the environment), but what's the point of the observation?
How does it relate to Dan's position?

:) That's the rating of the tire, not the tire/car combination. Those tires
fit many different vehicles. A heavier vehicle require up to 44psi, but
yours doesn't.

He is right. If stepping on the balloon causes the skin to exceed its
capacity, then it behaves just as it would if it were at a high altitude,
and for the same reasons.

stepping on the balloon puts MORE force on the outside(pressure)....high

Yep. The altitude and balloon thing shouldn't even have been in the thread
because it has nothing to do in reality with the tire issue.

So Joey, you're saying that when someone steps on a balloon and it pops it's
really imploding. You're saying it doesn't develop such high pressure inside
that the balloon finally bursts from the inside out?...???

Well, it sort of is similar. As the balloon rises the pressure outside the
balloon drops. The skin of the balloon can't contain the higher pressure
inside the balloon at a fixed volume (because the skin of the balloon is
neither strong enough nor rigid enough) so it stretches...and
stretches...and stretches. This stretching lowers the pressure differential
between the inside of the balloon and the ouside of the balloon by allowing
the the internal volume to increase.
This continues until the skin of the balloon ruptures.
This is also what happens when you step on a balloon only you reduce the
volume for a fixed amount of a gas (the air) by distorting the shape of the
balloon until the pressure is so great and the skin has stretched so far
that some part of the skin of the balloon ruptures.
When you add weight to a car you distort the shape of the tire. This
distortion reduced the volume inside the tire. The tire stretches some to
help keep the pressure differential reduced but it can't stretch enough to
totally compensate so the pressure inside the tire increases.
When you have a fixed amount of gas (in this case air) in a container (the
tire) and reduce the volume of the container the pressure goes up. This is
why the tire pressure goes up as the weight it is supporting increases.
You already admitted the shape of the tire distorts. Now all you have to
wrap your brain around is the fact that when you distort the shape of the
tire you also reduce the volume inside the tire and the pressure increases.
I'm not going to go into the calculus supporting this. You're just going to
have to research that yourself.

it is neither brilliance or bullshit...it is just not comprehendible to a
dumbshit like you... you did not quote the entire statement above trying to
prove a point(your point) but it still does not.... i never stated the
balloon implodes(since your reading comprehension wont' allow you to
understand what i *did* write you have to try and make shit up...quote me
in context or don't quote at all you fucking moron).... you step on a
balloon, or i could just step on your oversized head, and the "pressure"
your foot puts on the surface does not change the pressure *inside* the
balloon, as you wrongfully stated.....it *displaces* it and causes the
fucking balloon to stretch....got it? probably not, but anyway, that is what
causes the balloon to rupture...not from *more* internal pressure but from
the surface being stretched further than it can handle...its so simple i
would think you could understand...but im not surprised you don't....

this is not correct...in the case of the balloon you are indeed distorting,
but the balloon stretches so the internal "volume' is unchanged...that is my
hangup....you seem to know what is going on, and you probably know your
original statement was a "stretch" to say the least, you are just trying
your damnedest to not admit it...

there is no pressure increase.... you would have to overload the tire beyond
what was the subject at hand to *ever* decrease the inside
volume....period... you won't make the tire smaller...it will burst first...

again you seem to have the theory, but you are still not quite there.... my
tires on my pu contain 50psi cold.....even when i slap a couple tons of
gravel on the back it still has 50psi cold.... this is not just me talking,
it is from training and actually measuring tire pressures...something you
have done neither of...

distorting the shape has exactly NOTHING to do with it....if you load the
tire(which is so far from your original, yet brilliant, statement it apples
to oranges) the air is displaced locally in the tire...this causes the
pressure to move inside the tire...so localized inside the tire you could
have more pressure but the overall read at the guage is the same...wrap your
"brain"(yeah right) around that....or get educated on tires....

In this case of the bursting balloon you are wrong. If you put a gauge in
the balloon you will see a rise in pressure when you step on it. Why?
Because the balloon is near enough its maximum expansion to burst when
stepped upon - it does not expand easily enough or fast enough for the air
to be displaced so the air pressure does rise considerably, then the walls
pop.

Yes - that's where you went wrong in the case of the balloon. In this case
you would have to squash an underrated tire one hell of a lot to burst it. I
am sure you have seen it happen at least once.

Yep. Those tires are rated/built to the task. It is too bad the balloon part
of the thread was irrelevant to the thread.

You breezed through tire school? Was that breeze caused by your snoring?
You said, "distorting the shape has exactly NOTHING to do with it...." That
means that you believe that when you have a fixed amount of a substance in a
container and reduce the volume of the container the pressure stays the
same. ARE YOU JOKING??? Have you never heard of an air compressor? Have
you never heard of an internal combustion engine? Have you never heard of
an air conditioner? Have you never heard of ...
Never mind. You're just making stuff up. You can't really believe this

Just an opinion
> 165/80 tires on a '72 Super.
Several months ago I had the front end on my '74 standard aligned at a
VW shop which has been in business for something like 30 years.
Driving the bug afterwards I felt that the front end stability was a
bit off, but put that down to the alignment. After several days of
this I finally got around to checking the tire pressure (165s, radials)
where I was suprised to find that all the tires were now at 32 psi.
Made me wonder is someone goofed, or the higher pressure is some new
recommendation. But I still adjusted the pressure back to values which
are closer to the recommended ones.

certified in suspension systems....ever done that? if not i doubt anyone
wasted the time or money to have engineers from Mohawk(Yokohama) come and
give you classes concerning tires....i on the other hand *did* have
those....you will NOT reduce the "volume of the container" (I.E. tire) by
adding weight....if you do, you have already overloaded the tire weightwise,
and the "point" is moot...tires, like every thing else are designed for use
under certain conditions...go outside that and you may suffer a
failure.....what adding weight has to do with your original claim that
having 35psi in a tire is suicidal, i don't know...do you? thats right
NOTHING.....just a spin to take the heat off you for being full of
shit....didn't work, you are still full of shit...to drive the point home
even more, the two reasons tires fail most are UNDERINFLATION and
OVERLOADING....and they BOTH fail for the same reason....HINT: its not from
being overpressurized....if you don't know what that reason is, i will
gladly tell you, but the childish "i'm right cause i wanna be" shit you have
been throwing out is getting tired....you are in over your head in this
"discussion" so you should either bail while you can or admit it and try to
actually learn something....the latter is the best so you don't spew wrong

Gain of nothing because it burst! At the moment before the burst, the
pressure was higher than before.

affects slip angles,stagger,rolling resistance as well as traction in both
planes.Street tires have a max inflation figure(measured cold) than is well
on the safe side.Even exceding this by 10 or 15 # won't lead to catastrophic
failure(but don't try this at home).More dangerous is underinflation on a
heavy vehicle.This causes heat and belt seperation(remember Firestone/SUV
