"I have a fair number of official manuals covering vehicle movement from the ASC through to RLC, nowhere can I find any reference to the term of ground pressure."

Clive,

Do any of your manuals cover these 4 vehicles and do they provide any information on tyre pressure?

Thanks,

Neil

A bit of background info on my request: I'm working on a project to calculate the combat power of units that fought Normandy. In the model that I am using one of the factors that goes in to the equation to derive the combat power of an AFV is its mobility. One of the components that go in to the mobility equation is ground pressure. From books that I have and the internet I have found the ground pressure for all the AFVs that I'm interested in bar the 4 in this post and 2 German AFVs.

I appreciate these may be 'how long is a piece of string' type questions but a 'best guess' based on something tangible is what I'm hoping to achieve.

Thanks,

Neil

Excuse my complete ignorance on tyres but what is the second figure from the values that I found?

Thanks,

When I tried to google the tyre types these armoured cars used I found this info:

Humber Mk IV - 10.50 x 20 RF

Humber Scout Car - 9.00-16 or 9.25-16

Daimler Mk II - 9.00-16 or 9.25-16

Daimler Scout Car - 7.00-18

I don't know whether that helps anyone answer my query or not?

Hi all,

I'm new to this forum and am researching ground pressure of some WW2 AFVs. Does anybody know what the ground pressure was for the 3.7cm FlaK auf sWS and the S307(f) half track? I believe that the S307(f) was the Somua MCG5 in French service.

Thanks,

Neil

Okay thanks but I'd still be happy to work out a 'best intelligent guess' if someone would be kind enough to let me know the length and width of the tyres these vehicles used.

Thanks for that Mike. I'm happy to work out 'best intelligent guess' values if someone would be kind enough to supply the length and width of the tyres these vehicles used.

Thanks,

Hi all,

I'm new to this forum. I'm looking for the ground pressure for the following WW2 British armoured cars:

Humber Mk IV

Humber Scout

Daimler Mk II

Daimler Scout

Does any body have this info?

If not I believe I can calculate ground pressure using the following 2 formulas:

1. Calculate average ground contact area by multiplying length of tyre by width of tyre

2. Calculate average ground pressure by dividing load by average ground contact area

I know nothing about tyres and a quick google search leaves me baffled! If anybody knows the length and width of the tyres these vehicles used please educate me!

Thanks[TABLE]
