Somebody once told me there is no such thing as a silly question. So here is an excellent question.
What is the reason for putting big mudflaps IN FRONT of the front wheels under the bull bar? The only reason i can think of is to deflect stones from cars driving infront of you.

i can only guess that it would come in handy to anyone pushing against the bullbar as you are reversing out of a muddy bog?

To stop crud splashing up from the front wheels, onto the bonnet and windscreen, when you enter a puddle or bog hole at any sort of speed. You must have had water splash up when you have entered a puddle or bog? These are supposed to stop this happening.

Dont know about other vehicles but 75/78/79s are shocking for that even at low speeds. Also if these Mudflaps have RM williams or MACK on them it could also be for spank factor

You will find that anything with minimal body in front of the wheels will send the mud and water onto the screen, gets worse on the 70 series when you fit a winch and bullbar as the bar is further forward and better able to deflect the crud upwards.

I still just don't understand how that happens! Especially at low speeds, surely the mud must be defying the laws of gravity to reach the centre of the windscreen????

Basically the water/crud is propelled forward and upward when the tyres hit it at speed to a point which is basically in front of your vehicle and at about the height of your windscreen (dependant on your speed at which you hit said crud). How it gets onto the windscreen from there? Basically it slows down it's forward momentum and your truck catches up to it.

Or CAT mudflaps. Definitely spank factor. Most vehicles with those front mudflaps usually have heaps of aerials, spotties, stickers etc. The whole B&S thing. Oh and don't forget the "RUM PIG" license plate.

First started seeing them on rally cars when I used to rally in the 70s. They seem to have progressed from there.

As said above, hit some water more than 10mm deep at speed and the wheel throws the water forward and up, the speed of the air pushes it back over the bonnet onto the windscreen.

Used to mount them at an angle forward like 45 degrees so they didn't catch on rocks.

These days rally cars have air dams on the front which help. Rallying is no where near as rough as it used to be. We were lucky to get over 160km/hr on a good road, now they are doing over 220km/hr.

These splash guards are really only intended for road and track use, and as you can imagine, would get torn off in a rougher 4wd sitiaution. They are really useful on the front of trucks, which is another place you see them, so some people are trying to copy that 'mean' look :-).

I have had mud splash onto the windscreen whilst driving through a pubble. It didn't even enter my head that this is what they are for. It's simple now.

A curtain of rubber hanging from the bottom of the bullbar could theoretically bend back under the vehicle and provide an aerodynamic curtain to cut turbulance and resistance. But then again... maybe not!
