Colcob, I understand the airfoil part, but not the first one.
If I set a tire standing on the ground, by itself, and get an air hose...why would it 'want' to move upwards?
Can you MSpaint a quick sum forces schematic?

Thanks Stregone, though, a picture's worth a thousand words.
What's missing in this one?

U fix that problem like this!!!!!! The most famous f1 car(not driver) ever.

It wouldnt because there woulnt be enough power in your hose :P I think it doesnt matter what kind of object you have, take a air filled balloon and blow air under it and I suppose it lifts up.

a little birdie whispered it into my ear

10 minutes to go

Bank holiday today, perhaps they'll take the day off

It's a hypothetical hose, it has unlimited power.
When and why do the forces sum up to a net upwards total?

I get it..

u didn't feel like going to school? do ur parents care? What r ur grades? i get straight a's

I get straight A's too, my average was 96.31 % so I think its pretty good. Of course my parents care. But when you go to school all year they will let you not go to school sometimes wont they? This is also caused by some other factors but dont want to tell them here maybe when there will be chance.

my parents would never let me skip.

Rappa_Z you are 12 years old. Better go to school regularly. YOu seem to be really addicted to LFS.

school sucks. Where's the patch info it's time?

School sucks, but not having a job when you grow up sucks more than going to school

16:06 UK time - no update yet.
that could only mean we'll get the patch today.

I hope not. Besides, who has said that the update will always be at 16:00? illepall

keep ur fingers crossed. It better be the patch 'cause i'm twitchin' with excitement. When will it release today?
edit: it won't be today.

Oh come on where is it im gonna destroy my F5 key

If it isn't there at 17:00 GMT, then it'll be at 20:00

dammit where the f*** is it!!!! I'm gonna s**t my pants again.

And if it isnt 20:00 it wil be 23:00 GMT illepall

Yeah, me too! I'm so desperate!

It's out! It's the new car list, check this: link

if it isn't at 23:00, it'll be at 2:00

In your first sketch you forgot that the tyre is not floating in the air, but standing on the ground. That means, while the air can "easily" pass on the upper side, it's easiest way is blocked by the tarmac on the lower side. That means on the lower side there is more resistance, because the air has to flow to the sides. This raised resistance results in a raised pressure and a raised force that is bigger than on the upper side of the tyre.
Imagin it this way: A particle on the upper side of the tyre collides with the tyre and floats along it's surface until it reached the topmost point where it flies way. On the lower side the air particle collides with the tyre, flows along it's surface towards the tarmac, reaches the point where the tyre meets the tarmac and is trapped there, with the tyre rolling into it's direction. This is where the air particle says to the tyre "go away!" and creates a force that is bigger than on the upper side of the tyre.
(Actually the tyre also says "Go away!" to the air particle, and they both agree to the compromise that instead of flowing below the tyre, the air particle will flow to the side of the tyre, which happens to be the more cumbersome path. The difference needed in energy leads to the lifting force that acts on the tyre. *about 2000 more words on this topic*)

I can't make a sketch of it because I'm on my laptop with no mouse. And you don't want a touchpad-sketch. Really, you don't.
