I'd hire him.

I have no cash so I'm stuck drinking hot water out of the coffee machine.

 

Then don't pull the stems. Just let the air out. Weight difference will be negligible, but pressure differences can be a concern if shipping via air. Though that sounds unlikely.

I couldn't care less about the valve stems, I sold these at a huge reduction so if he needs to replace the valves then so be it. They are being freighted to him by truck most likely.

Consider the following:
gas volume of tire:
~27 liters per tire, maybe less
pressure:
2.0 atmospheres (about 29 psi)
Temperature:
20 o C or 293K
molar mass of air:
about 29 (20% O2 (32) and 80 % N2 (28)
R = universal gas constant 0.082 L-atm/mol-K

PV = nRT

2.0 atm X 27 L = grams of air /28 g/mol X 0.082 L-atm/mol-K X 293K.

grams of air comes out to about 65 grams (about 2 oz. or 1/8 of a pound) per tire

Don't bother.

Yer smart

 

I may end up hand delivering them anyway. Shipping company wants to charge $300. F that.

Nope. Just crafty.

 

I'm too dumb to get that.

 

i believe it is the number of molecules in a mole.
