tires have almost no grip

[Valentine]

when i make a car and export it to beamng, no matter what tires i use there is almost no grip from the tires and they constantly spin under any throttle, it's really annoying and makes them hard to drive. is there any fix for this?

• Downforce
  
• Weight distribution
  
• Proper suspension tuning/alignment
  
• Practice

If you're comparing grip levels to exported LCV4.2 cars, just bear in mind that they were wildly inaccurate in that version, with probably 20-30 percent more grip than they should have had.

In the lead up to the Ellisbury Update, we and our beta testers spent hundreds of hours benchmarking real cars to ensure that the cars they designed would produce results that matched reality in Automation, but also in the exported car as well.

Indeed. While we're on the subject of benchmarking real cars, here's a replica of a 3rd Gen Viper ACR. Try it in Beam and since the file contains a .car file as well, you can import that into Automation to reverse engineer it for tips on how to make a car grip.

Honestly OP, you've given so little information that we can't really help you here as there could be any of dozens of issues causing wheelspin like that.

What kind of car is it?

What kind of power delivery does the engine apply?

Are you using a keyboard with no traction control?

What are the widths of the tyres on the drive axle/s?

What is the weight distribution? Where is the centre of aerodynamic pressure?

In the transmission section, you have the graphs that show your power vs grip - does the behaviour in BeamNG correlate with where you are expecting to get wheelspin according to the graphs?

If you are really getting stuck, a real-world race engineer put this up on Steam a few years back, I'd recommend it for any sim-racer or Automation+BeamNG player:

Well, I think you may have designed the engine power too high. I feel the physics engine of both games are very realistic. It may be helpful to refer to the g force your car can withstand in the tire design or aerodynamic design screen.

I'm not designing high-performance cars. The worst example of the lack of grip is on a 2 ton, 300hp, 4wd pickup truck. And it's not just the tires spin when i accelerate, it constantly oversteers and understeers at almost any steering input. Is this just a suspension issue?

I was having the same problem,i looked on utube for steering wheel setup and it helped but i have only driven Beam cars as i now cannot upload cars to Beam,when you finish your build at end you can see stats and in there it says suspension tuning ive messed about with it and dunno whats going on its something like -25 if you can work it out lemme know that could be the issue also i cant work out circle test

Basically means no off-roader can make it up a hill now on Johnson Valley
