Surface pressure...

(1/3) > >>

V8MoneyPit:
Just done a quick calculation. Must be bored!

Although it can be manipulated in more than one way, I reckon the surface pressure is less for a 4x4 tyre than a horse shoe. Using a rough estimate of a 235 tyre contact patch, I reckon my Suzuki creates about 6psi surface pressure, whereas a 6" diameter horse shoe is about 8psi. To do the job properly, you would need to work in the actual tread pattern of the tyre. But I reckon, even allowing for the gaps between the tread, they work out about the same.

An average walker would create about 4psi, I reckon. Not the huge difference that you might expect.

Anyway, I think I should go and do some more work before I go home!

all i know is ,in a head on crash the 4x4 will win  :lol:  :lol:

Manicminer:
I 'guess' that my Isuzu has a ground pressure of 19.86psi.

It gives a good reason for sinking in wet ground.
