    Wouldn't the vehicle lift up a bit if under water from the pressure in the tire?

    If the car weighed 1 pound...

    the buoyancy provided by the air tires is so incredibly small it's not even worth considering. Even the weight of a bear frame would sink the car.

    Ok. Guess I over estimated it.

    The tyres are under the vehicle and dont provide enough bouyancy, so no, nothing would lift up.
    If the vehicle was upside down, maybe then the suspension might get an ever so slight pull, but even the unsprung mass on a car is usually too much for the tyres.

    Plus BeamNG has no bouyancy whatsoever right now. Only drag.

    Pretty sure it was one of you guys ages ago that said Jbeamed objects cant float. If thats changed, can we get a dev blog on it.

    It changed I think, I found a function called "addPressTri" in BeamNG.lua (line 1896) which would mean we can create pressured triangles. I don't know how to use it tho.

    I've had some hilarious instances with the new tire model when they get torn off, very much like when a balloon gets let go. The old tire model was definitely impressive when it
    bounced around the landscape, quite realistic.

    The lightest wheels are around 16lbs each... normal wheels are easily around 25lbs. I don't think even a wheel would float.

    The only time I could see this coming into effect is if something like this were to happen...



    but seeing as there is curently only one mod that is a monster truck (not even an official vehicle) then this isn't a feature that is really needed yet... until slapping some 55s on the D series is an official thing that is...

    A wheel with a tire on it would certainly float. As long as the wheel wasnt still attached to the car that is..

    A wheel on it's side... it's a thing called buoyancy and related displacement.

    Surely a wheel on it's side would indeed float.

    But high pressure air is denser and therefore less buoyant isn't it?

    Its slightly heavier yes. But still a lot lot less than water.

    Scuba divers are about the only one's who worry about buoyancy issues with compressed air. The weight of air in a tire at 35-40 psi is negligible
    and would need to be factored in with the air entrained in the tire rubber as well as surface areas.

    Depends. We have to differentiate weight and mass here. And we'd have to know the volumes too.

    Archimedes and Newton FTW!

    What about the monster trucks?

    You dont need to know the volumes. Something less dense than the fluid its placed in would float in that fluid. WHich in the case of air at 30psi, yeah its less dense than the water so seems it would then be down to doing the actual maths for bouyancy vs the weight of the rim + rubber.

    I still dont imagine it being very bouyant considering the number of wheels sitting on the bottom of the river in town.

    Don't see where I was burnt, but maybe I should go and fake my own death by drowning in wads of cash while driving a veyron.
