Foam in tires
Has anyone heard of or have foam sprayed in your TT tires? Dealer convinced a friend of mine this is the way to go because he will never have a flat tire.

OK, I will break my policy of never trying to educate those sheep who blindly believe others without any critical thinking that they should have been taught by at least their educators, if not their parents.
air is 78% N, 21% O (rounded for simplicity of those that hate math)
the average tire is about 10L. meaning (for those of you that hate math....and yes, I am using the metric system to laugh at those people) there is 7.8L of N and 2.1L of O in the average tire. if you want to argue that YOUR tire is a different volume, go ahead and do so but I will not do the math that you hate so much for you.
the shysters who sell N say 'N wont leak out like air will'.
running with that bit of 'wisdom', lets say you lose 20% of your tire volume before refilling with air. you can argue when YOU refill to your hearts content but I will not do the math for you if you start that whine.
so,that's a loss of .2 x 10L = 2L of air.
hmmmmmmmm. that number looks familiar. pretty close to 2.1L isn't it?
dang near already have pure N in that tire.
so the refill air contains (again) 21%O which is .21 x 2L = .42L of O
huh-oh, we now have a tire with less than 1/2L of O. so we added .42L O to the remaining .1L of O which is .52L of O in the tire after ONE REFILL. that's already a N content in the tire of 95%. imagine what TWO refill would do (actually you don't have to imagine, just DO SOME MATH...and I am not even going to try to explain how to set up this problem via calculus).
yes, there are small fractions of Ar, Ne, and CO2 and such in air but they amount to only something around .973%. if you want to do math with those components (and I bet you don't), you get to do them yourself.
It really does depress me that our culture has come to the point where they blindly follow someone without critical thinking or applying the Scientific Method in even the simplest manner. Or maybe its just that some folks prefer to argue and get a rise out of others. Sad if that's what your life has become.
Regardless, I am done with this thread and you, blocking you and ignoring this thread. It really does make me sad, so in that sense you may have accomplished what you wanted.
