    Well for the past days im having fun playing the game on 18-35 gravity do have increased tire traction and it make drifting easier and racing and stuff.


    Any idea if tire traction will be improved it seem to be complicated to control the rwd in hill and straight line most of the time.



    Im having fun currently with those setting and tranny clutchtorque at 8000

    "enginetorque":[
    ["rpm", "torque"]
    [0, 0],

    },


    The tire are inflating to death and im hitting 400mph ;) I would be happy to be able to do wheely like real life drag truck

    ( it the pickup truck offroad im using 4wd and the 2wd one v8

    Well you're using factory tyres, of course its going to have trouble laying down stupid horsepower amounts....

    I thought the "slidy cars" threads would go away.

    the race variants of the cars pull at, a little under, or over 1g, which is in line with real handling figures. I dunno about you, but I can handle the Bolide 390 around the track, up hills and whatnot without even breaking traction on the rear wheels.

    Tire traction will probably increase a bit as pressurewheels are refined a bit further, but they're pretty damn good already.

    Well offroad traction on a rwd is worth 0 in beam ng currently i cant go up a small hill.


    The car are slidy explain me why the front of a FWD car wont stick to the ground in a turn going 60kmh it should flip in real life Yea when you turn the steering completly something bad is suppose to arrive but currently the car just go in straight line :confused:



    I have real life experience offroad and i must says RIGS of rods was more realistic almost. Hauling was making pickup wheely and stick Beam ng you can put a car on the back of the pickup and the thing cant lift the front at all


    I must add Ror did was able to Drive over water too with overpowered stuff in old version of the game.... Beam ng well water is nothing currently but it the kind of thing im waiting for.

    ( i have no idea if the engine can do that either ) I still love the game :D

    - - - Updated - - -

    I must says maybe having a locked diff would help stay in straight line while the current open just push arround corner like crazy



    Btw i have a 360 controller and a g27 and over 200 hour of gametime so i do know the game

    - - - Updated - - -



    am not talking about my overkill thing ahah This was just for fun. Reality wise the truck would be impossible to have 20000lbs feet of torque. maybe 800-1800 possible but not more


    THe problem is with stock vehicle

    no, it shouldn't. Cars are designed by manufacturers to understeer instead of flip for safety reasons. Just look up the moose test, you'll see that every FWD car goes nearly lock-to-lock, even without TC, ESC, or ABS, that none flip over. You need to start looking at some pretty shady tall SUVs before they start tipping over.

    also the traction thing; the tires are not the problem. It's just that the terrain in BeamNG, even when the ground model is set to grass or mud, is essentially completely rock solid. IRL, even gravel and hard grass have some softness and depth. If you want an authentic offroading experience, open groundmodels.lua, find whatever substace you're offroading on and change the default depth to something like 0.1. You'll see it DRASTICALLY changes the way traction and pressure works with the tires.

    No FWD car flips. Having barreled through bends in fwd cars quite extensively myself, I will say now they will always understeer, hell, they rarely even lift a wheel from the ground (they certainly can if the suspension is setup correctly - or rather wrong, but majority will keep all 4 wheels firmly on the ground at all time). The only time they dont understeer is when you induce oversteer beforehand at which point all 4 wheels will still be on the ground.

    60kmh isnt even 40mph, full lock at 40mph definitely just causes the front to slide out, I've done it (on private land in a space with plenty of runoff). Yanking left and then full lock right quite nicely induces oversteer before you stick in a bit of countersteer, a thing I have attempted and somewhat succeeded but am not any good at, need alot more practice which is something I prefer to do on looser surfaces in the first place and dont have all that many to try on so don't. Car still doesnt roll.


    I dont have any major problems with offroading when using a proper technique which leaves me to believe it is your driving style not the game. The offroad diff for the D15 is limited slip not open. Stick that on.

    Driving over water has been demoed in BeamNG.

    There are several FWD cars that flip. The base model Ford Fiesta is banned from SCCA Autocross competition on c.g. alone (to give you an idea what kind of company it's in, other banned-for-rollover cars include the Jeep CJ and Suzuki Samurai), and I've heard the ST is a rollover hazard as well (the first thing a typical autocrosser does is upgrade to ultra-grippy tires, which then causes the small anti-roll bars to overload). I think the base models of Dodge Caliber and Suzuki SX4 may also have received that same "honor", though that may only be the AWD versions.

    Well of course they flip on racing tires.

    Also the Caliber doesn't flip, I had one as a rental for a vacation and I had to do some defensive driving on a mountain road when a big semi rolled into my lane. I went nearly lock to lock and the thing kicked out the back a bit put stayed put.

    The nissan micra under racing lift 2 tire at like 40-50 kmh and would flip if you want to. and it a fwd car Racing tire as nothing to do with it.


    If you turn at 100kmh i can garantee you that something will happen bad. the suspension is independent mean that the suspension will drop and the wheel may lock on the ground

    No, nothing is going to happen on perfectly flat ground.

    I've done this at 80km/h, I got chronic under-steer, when I yanked the wheel the other way I got some over-steer but not enough to lose control. Sure, you could lose control if you tried, but will you flip or do serious damage? Nah, maybe some screwed tires perhaps.

    I'll personally go and put it to the test in my FWD car to prove you wrong if necessary. (If I can find a place to do that, of course. I did it at 80km/h on privately owned land 2 hours from here).

    EDIT: In that video you show, it gets on two wheels because he went straight over the curb.. And yet it still doesn't flip.

    Plus there is a drastic road camber change, that alone can easily cause a wheel to leave the ground, its essentially a low altitude ramp. There is a section on the farm drive with pretty major change which causes problems at speed for stepdads BMW 320d let alone my old corsa c/barina 4 which was perhaps one of the poorest handling vehicles to grace this earth.



    Anywho.
    This car:
    WP_20150712_13_45_55_Pro.jpg
    This bend:
    WP_20150712_13_42_00_Pro.jpg
    WP_20150712_13_42_15_Pro.jpg
    Coming along tree line and swinging right around the sign and concrete post. In event of understeer the area being entered is pretty wide and the edge of that field contains no crop and is reasonably solid ground flat ground (it hasnt been ploughed in many years).

    Plus a bit of a change in road height too.

    End result.
    WP_20150712_13_41_45_Pro.jpg
    You can see a faint tyre mark, that is indeed new. The tyre that caused that was this one I believe (was notably warmest to the touch afterwards aswell):
    WP_20150712_13_45_25_Pro.jpg

    No wheel left the ground (trust me on that, I've had enough wheels go airborne on the farm drive to sense it). The car most certainly did not flip. Nothing broke.


    Entry speed: just over 40mph with the throttle held down the whole way through it and at full lock.
    Did flick the wheel left somewhat before full lock right and you can see where my "drift" skills are somewhat poor as I still managed to overturn towards the warehouse just out of frame (on right side) rather than countersteering it into the middle of the tarmac area as intended. But no roll at all, if anything I'd expect the oversteering car to be even more prone to rollover than the understeering car.

    No issues here.

    Have also ridden passenger through same bend at 30mph in this polo, which did understeer towards the grass but also didnt have a scandinavian flick entry. While I would attempt the corner myself, it is my brothers car and fitted with an insurance black box, I refuse to drive it recklessly when it can come back and bite his arse, he's also out of the country right now so I cant just ask him if hes alright with careering through a bend at full lock at high speed while full 11 axis position measurement is taken of the vehicle and sent to his insurer.

    As an added bonus. Please enjoy the english summer weather in images 2 and 3 which really cant make its bloody mind up about blue or grey sky. At least its not raining (although england genuinely doesnt rain as much as stereotyped).

    Weather has made up its mind now. Rain it is...

    I love people arguing when youtube show about 200000 video about stupids people flipping their car at 20kmh in russia and other arabian country that like to run TRuck on 2 wheel for fun


    With cant do that in beam ng even if i tried sideways

    Well.. This isn't getting anywhere... Feel free to edit your BeamNG.drive cars to suit your needs and flip at 20km/h.

    Locking thread.

    Re-opening this thread for the sole reason that OP still have dubts on this. Better to clear them out.

    Tire tuning is an essential part of any driving game, and in BeamNG that isn't done blindly by changing values till they seem OK.
    That is done after accurate research. Goosah already made 2 detailed blogpost on how that is done and how he gathered his data >> http://www.beamng.com/blogs/19311-Goosah
    On a side node, he is keeping working on tires. His work isn't done and he keeps fine tuning each vehicle to get the better out of them.

    An RWD car can't keep going straight while going over a hill? It would be reasonable if the car is mountin 'street tires' and also depends on which surface that hill is made of (for example 'grass' is a pretty slidy surface).
    Those would just slip on the surface making the rear-end of the vehicle lose control.

    FWD cars flips? Some of them.
    Those who have a high center-of-gravity point do. Those who have terrible suspensions do. And most cars have swaybars (I believe all, as that should be a safety standard) that prevent flips and roll overs.
    The covet and the Sunburst base model (The only FWD cars in BeamNG currently) doesn't have a high COT point, nor wobbly suspensions.

    Now, on 'personal point of view' this seems one of those thread where the op thinks must he must be correct no matter what and whoever tries to say else is an idiot with no experience. But that's just a personal opinion.

    You started the thread and the discussion about cars flippings. You don't have anything to wonder if people reply..

    A car flipping at 20kmh is:
    -Extremely dangerous
    -Probably a POS of car
    -Would fail any test that will allow it to be driven on public roads

    Also, you are jumping from one discussion to another.
    First the RWD car and hills.
    Then FWD cars flipping (In that Nissan Micra video, as Drowsysam underlined, the car jumped on a curb and the road is not flat)
    Now 2 wheeling trucks (In that saudi video, the truck probably got his swaybars removed/customized. Or the passengers are transfering weights from inside the car. Seems quite unlikely that a car manufacturer would be allowed to produce a car that would flip at such low speed.)

    To reply the question in the Thread Title:
    Yes, gravity affects handling. It would put more load on the wheels and increase friction between the tire and the ground. And also gives the impression of 'stiffer' suspensions.

    Can you please make your point clear? What is your problem with BeamNG? What is your ACTUAL suggestion for the game? Write it in clear words without going around it, please.

    If you think I'm wrong, I please you to sustain your point with valid points or resources.

    Pretty big angles here, so steep that my car would slide down.

    74f61c2864.jpg ca0656b0b6.jpg

    Tried to 'flip' my car at 60km/h. My car is a very good example of an ordinary FWD car, and it has very soft sway-bars too, so if a FWD car is going to roll, it'd probably be mine. Also very closely related to the Ibishu Pessima.
    Video - Click to Play - Direct Link

    (My mic is covered by the way, so you won't hear much)

    Conclusion:
    • It's not going to happen
    • I got lots of under-steer
    • It hurts my tires
    • It throws me around a lot

    Please stick with your original argument about FWD cars flipping at 60km/h, not 4x4 SUV things that probably has removed sway-bars and/or is modified in other ways.

    Note: These aren't even public roads any more, they're all abandoned due to the earthquake a few years ago.

    i want RIGS OF RODS FUNN BACK. Hauling stuff and breaking the frame hard

    Do wheelie with truck and heavy load and stuff.

    ROLLOVER CRAPPY CAR

    Ok i understand that most recent car wont flip But the micra i showed is a brand new model for the north american market and was on 2 wheel.
    Maybe adding the mix of racing tire or high end.... But still that crap was driving on 2wheel. The current car in beam ng have probably better center of gravity. But that just the kind of thing i want to learn on and see the game update i know they do lot of work into that tire thing i read the update log and blog often


    . But i was halfways right that lot of car flip... Older one do Truck do Small Car suv that are now illegal because they flip like suzuki sidekick and stuff.


    Currently the truck and crane lover off Rigs of rods having nothing more to do than play ror... And im here with my new pc unable to play ror because well most map crash for no reason...

    So, the conclusion is:

    -This is not Rigs of Rods
    -Only crappy FWD cars would flip at 20kmh
    -The crappy Ibishu Covet is not crappy enough to flip at 20kmh
    -An FWD car flipping at 20kmh would be banned from public roads.
    -The trucks in those video are offroad truck, coming off an inclined road and are obviously overloaded as written in the video title.
    -If you want your cars to be crappy and rollover at 20kmh, you are free to mod them with some ridiculous suspensions/tires.

    Should be noted that many cheap fwd cars only have a front sway bar. Actually my first car (Skoda Felicia) did not have any sway bar, although its rear suspension was also not independant as both wheels connected to the same trailing arm assembly:
    SDC10864.JPG
    Seriously, only roll you were getting in the rear suspension should be from flex in that single hunk of metal rather than seperate geometry. It was hinged onto the chassis at the front and had the shocks at the rear. Entire thing moved as one. So while I lacked a front sway bar, I effectively had the stiffest one possible in the rear. Front was macpherson, think a *few* models had front sway bars.


    My corsa only had a soft front sway bar, actually I drove around for ages in that without realising the drop link had shattered so I effectively had no sway bar as it doesnt have provision for mounting a rear one. Corsa also had alot of flex in the front wings though, would have really benefitted from a strut brace.
    Focus I think has front and rear, plus the rear suspension is fords control blade which is just damn awesome (kindof a weird hybrid of a conventional fwd cars rear trailing arm setup with some multilink stuff thrown in), it may have been an unfair test for rolling a car considering the focus is a seriously well handling vehicle for the segment (hell, VW went and based the next gen golf suspension off of the focus after its unveiling, the VW system is slightly different to avoid patent litigation, but achieves the same effect).
    The polo outside, soft front bar, no rear bar.





    If fwd cars specifically were rolling over at an absurd rate there would be mass hysteria over it. That alone speaks for itself.
