The OP clearly said sports hard tyres.
The amount of grip racing tyres give are substantially greater than road or sports tyres, so you saying that hard racing tyres gives the same amount of grip as standard tyres Ferrari use on road cars is not correct. Road or sports tyres have tread patterns whereas racing tyres have none, the more rubber in contact with the road the more grip you have. This is why a few years back F1 introduced grooved slicks - to try and slow the cars down because the grooved tyres had less grip.
There are different ways to make a car go faster, when you are driving a very powerful car on stock (or sports hard) tyres, driving sklill and technique, equiptment, knowledge of the track and understanding of the car's natural attributes and tendancies are important factors in determining a lap time, especially around Nurburgring.
Anyone can modify a car, throw on a set of racing tyres then claim a fast lap time compared to a stock version of the same car.
Whether you like racing or not has nothing to do with the tyres you are using, quite often when I race my friends online we use sports tyres, the racing is clean, competitive and usually very enjoyable.
Racing soft tyres are not the 'way to go', these give a huge amount of grip and can reduce most stock road cars to just being giant go karts. The skill involved with driving a road car on racing soft tyres fast, especially stock road cars, is minimal. The amount of grip racing soft tyres give dramatically changes the natural characteristics that often gives a car a sense of identity in the first place.
If you're going to throw racing soft tyres on everything then there might aswell just be a handful of cars in the game, but there isn't, there's over 1000 cars, and finding out what alot of these cars are like, individually, is something alot of people get alot of satisfaction and enjoyment out of doing.
