putting water in tyres??

[82 Lux]

Nitrogen in tyres is to maintain a more constant tyre pressure due to the fact that it expands less than air when it is heated/cooled. Only a small difference in pressure from cold to hot. Unlike normal air. All race cars and aircraft use nitrogen for this reason. As for a daily driven street car, harldy worth it. Let alone a 4x4 that when you air down for the track or beach do you carry a N2 cylinder to air up again??? Normal air will do me.

That new de-hydro sounds like the new alcohol on the market called
AWOL yes its alcohol without liquid , which makes it a vapour selling next week apparently .

Why!!!
because they can .
saves liver and other organs but hell on the brain.

maybe christopher skase had the demo model on when he was in spain and look what it done to him!

with water in the wheels .....

can your 4b be driven at road speeds


will the water move around the tyre at higher speeds

like a centrifugal force

Carnt drive very fast at all. Once the water starts to stick to the outxside of the tyre and mover as a solid lump they get out of ballance big time.

Im guessing 60Kph max.

but what about a small amount ??...wouldnt it act to balance the tyre ??

[ORSM45]

it would be worse wouldnt it?, because it would be looking for the furthest point from the centre.

Im thinking that if you ran 44s full of water and did roll it it would come down a lot harder. When tractors roll you wan't a very good cage!!!

I know that my uncle fills ALL the tyres on his 3 tractors 100% full of water (then a tiny bit of air to get up to pressure). He says it is because he needs his C of G as low as possible because his farm is extremely hilly.

Also eliminates a lot of moisture from inside the tyre where it can cause the tyres to wear internally more quickly, ever seen the little rubber ball bearing like deposites in tyres, that is the inside of them falling to bits due to moisture and general wear, nitrogen apparently help reduce that.

Surely anything more than axle height is raising the COG?

As Ben Boynton detailed the pressure inside the tyre remains more constant with temperature change if nitrogen is used, the second advantage is that nitrogen a a dry gas and that is very benificial to the internal high speed tyre carcass (tractors slow speed water is no problem)
thirdly if tyres are run underinflated for long periods of time or distance the tyre generates large amounts of heat this inturn can break down the rubber material and creates a conbustable gas (the smell you get when a tyre has run flat) inside the tyre this mixed with the oxygen in air and enough heat can cause the tyre to explode, nitrogen being and inert gas can prevent this from occurring this is more of an issue in large heavy mobile equipment.

[/quote]

Only if CoG is at axle height. Any additional weight above CoG will raise CoG, Any additional weight below CoG will lower CoG.

In simple terms, as soon as the CoG passes directly above the lowest point in contact with the ground (tyre) it will fall over, the lower the CoG the harder to pass it vertically over the top of your tyre.
