The short answer
The wheel is telling you how much grip the front tyres have. Steady, building weight means they are loaded and working; the moment it fades or goes light, the fronts are sliding, so ease the steering rather than adding more. Set the gain so the strongest forces just avoid clipping — firm and clean in a straight line, a smooth continuous push through a fast sweeper.
You might be tempted to crank the force feedback up until it feels like arm-wrestling. That is noise, not feel.
Cornering, a steady building pressure means the tyres have bite. When that pressure starts to fade or go numb, the front tyres are letting go. A light wheel mid-corner is not a fault — it is the car telling you it is sliding. Ease the input instead of adding steering lock.
Set it so the strongest forces — heavy braking, a big kerb hit — just barely avoid clipping. If it buzzes constantly you are overdriving the signal: turn the gain down until it is firm but clean.
In a straight line the wheel should feel heavy without fighting you. Through a fast sweeper you want a smooth, continuous push rather than a shudder. Vibration at low speed is just the tyre model being chatty — ignore it.
The wheel twitches over bumps and kerbs. That is information, but not always useful information. What matters is the trend: the slow build and release of force.
If you are fighting the wheel, you are fighting the car. Relax your arms and listen with your hands.
Gain is personal and depends on your wheelbase. If you cannot feel the front load up at all, that is usually gain or filtering rather than your driving.
