I would imagine it costing less if you have the tires mounted seeing as it would take up less volume.

As for air or no air.....well air is pretty light so that won't make much difference

Call whomever you are going to ship with and ask them.

 

The weight difference is going to be insignificant.

Having adequate pressure in the tires is needed, both to keep the tires mounted on the wheels, as well as for the tires to protect the wheels from damage.

Always ship wheel/tire assemblies with the tires inflated to at least normal levels.

 

ask to put the air in a seperate box

 

^^^lol^^^^

 

Believe it or not, air is pretty heavy. Mythbuster's said that if a column was put up around the Eifle Tower, the air in the column would be more heavy then the actual tower. Also, at something like 15psi, can't remember exactly, air will make a football like 8 ounces heavier. I would guess you could save prob like 4-5 lbs taking the air out of tires to ship.

Nonsense. Your own source, mythbusters, says that the air in a football weighs 3.2 grams. That means that you would need to inflate 142 footballs to hold a pound of air.

Again:

The difference in weight of the air in the tires is going to be insignificant. Remember, shipping rates are calculated by weighing in pounds, and unless the wheel/tire just happens to weigh 39.95 pounds (so that the extra ounce of air in the inflated tire just happens to be the difference between 39.95 pounds and 40.05 pounds), it's not going to matter (and even if it does, you're talking about a difference of a few cents).

Having adequate pressure in the tires is needed, both to keep the tires mounted on the wheels, as well as for the tires to protect the wheels from damage.

Always ship wheel/tire assemblies with the tires inflated to at least normal levels.

 

PV=nRT Ideal gas law which air, in most cases, follows.

Air at sea level, 15PSIA or 0PSIG, weighs about 1.25 kg/m^3. Your tires are inflated to about 45 PSIA or 30PSIG.

In a 16" tire there is maybe about 0.03m^3 of air. So at sea level pressure there is 0.0375kg of air in a tire.

At 45PSIA there is 0.1125 kg of air.

So if you deflate from 45PSIA to 15PSIA you would save about 0.075kg of weight per tire. That is about 0.17lbs. 4 Tires mean 0.68lbs. Yeeeeha! Like NSXTASY said, it's nothing.


As for the Eiffel tower thing....well:

Weight of the metal structure: 7,300 tons
Total weight: 10,100 tons
Height: 324m (height with flagpole)
Base: 124m.


so a column the size of the Eiffle tower would be 324X124X124 (it's a square column) = 5X10^6 m^3

The weight of air of that would be about 6 200 metric tons. Oh wait, that's less than the wieght of the tower. How could that be, Mythbusters said it was true?!?!. Well lets make some mythbusters crazy assumptions. We will make the column round that way it encompass more volume even though the tower has a square base. Then we will neglet all the other stuff on the the tower, we will only consider the weight of th steel structure.


Lets just assume that the the column now would be round. That would make the radius about 88m which would make the wieght of the air 9 800 tons.

Why use a round column and neglect the wieght of everything else? Well it cause mythbusters always plays with the numbers and facts until they are in their favour. They are there for entertainment, not science.

Anyways, that's enough morning math for me.

Cheers.

 

Thanks for the math lesson. My memory must not be what it used to be. Thanks for clearing up a few things.

LOL, sorry, I was just bored this morning getting up and really didn't fell like doing something overly productive. Hopefully the crap I wrote is correct..

Cheers.

 

We ship wheels and tires inflated. Helps protect the wheel. Weight is not an issue. Only issue is size and service.

Like I said...

 

answer to your question is No.

ARE YOU FOR REAL????? THIS IS A JOKE RIGHT??? I SAID IT BEFORE AND I'LL SAY IT AGAIN, IF YOU PEOPLE ASK DUMBASS QUESTIONS LIKE THAT, "DUUHHHH, DOES IT COST LESS FOR SHIPPING WITH NO AIR???" THEN SELL EVERY WRENCH AND RATCHET YOU OWN CAUSE YOU OBVIOUSLY HAVE NO CLUE TO WHAT YOUR DOING!!! ESPECIALLY IF YOU USE MYTHBUSTERS AS A GUIDE TO MECHANICS, STOP IT! JUST STOP IT!!!

He didn't know and he asked a question. That is a sign of intelligence; recognizing a lack of knowledge and seeking it.

You, however, are just belittling someone. Honda-Tech is there to help others. Not make useless posts like this. And I wouldn't talk too much, at least the OP knows how to use the 'caps locks' key on his keyboard.

Technically it would wiegh less and there for cost less. However it is a negligible amount and it is far more benificial to keep air in to protect the rims.

Dude, that is not intelligence. THAT IS DUMB. And as for you, you contridicted yourself after you did all that math to sound smart and prove that air does add weight and the turn around and tell me that it would weigh less WITH air!! Get a life and stop your crap to sound smart.

One thing i do agree with is that HT is here to help people. Help people with their honda problems. Help people fix their cars not their incapicities to think thru a stupid question like that on their own.

Is it cheaper with/without air to ship??? LMFAO @ both of you!

I have to agree with nsxtasy, mounted and inflated is to save space and protect the rim.

 

^^^ he said it would weight less with out air, but not anywhere near close enough to save money at all.

you completely misread what someone said to help another member on here and sounded like an *** while you were at it.

Its simple. does air weight anything = yes, would it be cheaper = technically yes, would it save money = no and finally, is it there to protect the rim = yes.


so bottom line, ship with air and pay the extra penny end of story. next thread.
