it's very clear for aqua planing! the more a tire is stretched over the water and easy to evacuate on each side


Your GS had narrow tires because they were lighter than current cars.
But if you put narrow tires on the current cars, certainly you will not have any aqua / snow planning, but you will not hold the road so far ...

Large wheels also increase the ground contact area (by decreasing the radius of curvature at the point of contact), hence the mode for larger and larger wheels.

Exactly. The large diameter allows an equivalent surface area with a smaller width (thus a much better water evacuation for the same profile and the same wear, of course)

It was, with a not too inflated tire, one of the key elements of the legendary handling of the 2CV, GS, etc ... Ave all the same, the suspension, the weight, the flat motor, etc ... C is a whole.

The handling of 2CV .... Indeed it is the only car I know that is able to change the setting of the outside mirror left just turning violently right .... : Mrgreen: Sailors have always confused it with a boat when the sea is formed. : Mrgreen:

inflating with tire with engine




by oli 80 » 16/01/11, 00:51

Good evening, here is what I fell on I did not even know that it existed http://www.lagitane.com/boutique/collec ... 72181.html

it exists with manometer on ebay
http://cgi.ebay.com/ebaymotors/G-H-Meis ... ccessories

Chinese continue to manufacture this inflator http://www.china-tiregauge.com/products ... 21705.html

in fact as I understood it is necessary to disassemble a candle and fix the provided end in place then the hose, the other extremity on the tire and the engine is idle

So we inflate with air + gasoline vapors. I'm not sure that the rubber of the tire and or the valve really appreciate the joke long .... it's a solution, just to not stay in an impossible place. : Mrgreen:

Yep, yeah, yeah ...
An inflator on foot is not more expensive (in Chinese version) or a little more expensive (Michelin *) but at least it does not waste gas!
And do not tell me it's more tiring! Because to disassemble a candle, it is not always simple, nor clean! : Lol:

inflator candle




by oli 80 » 16/01/11, 11:21

Hello, actually when I found this on the net by looking for old objects by chance, I found this system dangerous, send gasoline vapor mixed in the air in a tire or to inflate other thing as we can see in the link ebay on the record of the inflator, in short I did not even know that this kind of accessories could exist

to buy this kind of stuff you really have to have the courage to live dangerously, moreover the Chinese manufacture and sell this inflator

the foot pump or hand pump remains the essential tool to keep in the trunk of his car

Yes, the advantage is that bullshit should be alleviated with this kind of system : Cheesy:

The mode of inflation by combustion is a system D when one does not have an inflator, but a flammable product and a lighter ...

Some do it with spray brake cleaner.

Example 1: car tire
Example 2: truck tire

Personally, I advise against this technique because there is a risk of burn (of the tire and the man), and the pressure of the tire can become enormous, until its burst / irreversible deformations like here.
