In reply to this, iRacing does a great job of letting you feel the tyre grip through the force feedback, while GT5's FFB is good for a console, in comparison to iRacing it is quite weak, and if it was improved the feel of the cars in general would be a lot better.
Judging by your avatar and sig i would have thought you would recognise or agree with that.
Classic trait of GT.. I dont really mind it much, although it was incredibly improved for gt5, compared to GT4 and GT5.prologue
All tires squeal, slick or street when pushing near it's limit. Slick is a lot softer than normal street tires and melt away a lot quicker so less squeal but they STILL do squeal when near it's limit. BUT, what I hate is how tires in GT5 react in the wet, tires loose traction a lot sooner in the wet and often not near it's protential limit so you hardly hear squeal IRL when compares to dry roads, but in GT5, wet tires squeal just like in dry tracks and it's very annoying...
The harder you push a tyre on a wet road the more it's tread does it's job in cutting through the surface water to let the rubber contact the tarmac so you do still get squeal at the limit. If anything not pushing as hard is more likely to cause a loss of grip as the tread isn't pushing the surface water hard enough to prevent aquaplaning.
If your tyres doesn´t make any noise, you are definitely too slow. Tyres driven at limit will always squeal...watch the Top Gear video with the FXX
It is Michael Schumacher. You will not find any guy who knows better how to drive a Ferrari.
