Hi there. This thread is a result of GTS' horrible tyre model simulation. This is a simulation of how the tyres gain and lose grip (not to be confused with actual driving of a car). GT Sport's tyre simulation is the worst simulation of all current gen simulators and simcades. PD has improved his a little throughout the updates but it's still shameful. What the tyre model affects: acceleration, deceleration, understeer, oversteer. What it does not affect: basically any kind of driving until tyres start to lose grip. Acceleration: this is the easiest way to test the tyre model via 0-100 kph test (0-60mph), which in GTS results in totally unrealistic times. FF cars are most affected, followed by FR cars, MR and RR cars and 4WD cars respectively. 4WD cars are less affected but still not realistic. The easiest way to test the tyre model is 0-100 kph test (0-60mph), which in GTS results in totally unrealistic times. FF cars are most affected, following by FR cars, MR and RR cars and 4WD cars are naturally not so far from reality. @Scaff also did a pretty good video comparing real life, GTS and other games' tyre model. Please post the video here, I could not find it anywhere. Examples of some 0-100kph tests: (I used TCS1 because that gives the fastest results, all cars stock, with stock tyres equipped) Dodge Charger SRT Hellcat: Real life time: ~3.4 seconds GT Sport time: ~5.8 seconds - ridiculously slow Honda Civic Type-R: Real life time: ~5.8 seconds GT Sport time: ~7.2 seconds - again, totally off BMW M4 Coupe: Real life time: ~4.0 seconds GT Sport time: ~5.5 seconds - once again, way off Conclusion: tyre model in GT Sport is ridiculously wrong. Generally speaking the more powerful a car is the bigger is the gap between reality and GT Sport. Accelerating in GT Sport feels like the car drives on ice rather than tarmac. Other weird occurrences are when not using CSA (counter steering assist) in a rear wheel drive car. Cars tend to drive just fine until the grip is lost completely and the car becomes a missile heading anywhere but not where you think. It's impossible to predict where the car is heading, how much you need to counter-steer, how much throttle can be applied. There is very little to no feedback (when using a wheel). When using 4WD cars, they seem to drift like crazy, they go sideways even under little throttle, again, no grip just spinning like and since all wheels are driven the car seems to go sideways rather than go straight. All tyre compounds are affected, including racing slick tyres. Another examples: Stock car, stock tyres (racing slick tyres) at 0:28 take a look how the wheels spin in 3rd gear like crazy, the car won't stop for a few seconds. Impossible in real life - the car has nowhere near as much power to outgrip the slick tyres - and even going backwards. a 900+hp Supra, wheels won't stop spinning even at 300kph https://www.youtube.com/watch?v=Aseebqcd5Ro 250 hp Impreza, no grip again, look at 0:53 especially. https://youtu.be/IrsS-a9pAmw Here's the Scaff's video. Please keep the discussion on topic, this is a thread about tyres, not about driving physics.
