So whenever I'm driving on worn tyres (<40% worn or an almost empty bar on the tyres info screen) my wheel starts shaking very much on a straight. On even slight corners its totally fine but once im driving straight it just starts acting like that. Do you guys have any solution to that?

Wheel: G25

Is this with all cars or a few specific ones? What FFB settings are you using?

You're probably driving an older car? It happends to me also on the 2002, 2002 stancework, 2+2 fastback. Even with cautious driving, 1 tire will go nut and you'll see the hud going crazy. Somethimes, you can even see it right at the start.


Edit - The only work around i found was to jack the tire pressure until the problem rarely showed up.

sounds like you should pit and change tires lol that should fix it if its only when on worn tires

Im driving a Corvette C7.R GTE so its a kinda new car and the tires aren't even worn 50% so yea the effect comes from the tyres but I dont think that is supposed to happen right?
Should I list my complete ffb setting? Im using kinda high values maybe that is a cause aswell but I dont want to tune them down that much until it doesnt vibrate/shake anymore.

Yes, that's not a car known for that type of behavior in the game. You likely have a setting cranked up which is causing it. If you want to reduce that effect, you'll have to show what you are currently using for FFB (global FFB settings and any car specific settings you might have set).

I always assumed it was supposed to be like that, vibration caused by the tyre starting to fail. Happens with every car I drive; LMP1, LMP2 & GT3. I'll have to check my settings!

Probably what you're feeling is tire scrubbing but with these two values maxed out, it feels much stronger than it should. I think most people use a tire force around 50-60 and steering gain at 100 (unity).

Ok I will try these out in the next days and report back whether it changes it. Thanks for the help :)
