> Imagine people who love driving must always be forced to use exactly one tyre enforced by the manufacturer
Actually that is exactly what happens.
Ok, maybe not one tyre, but a small number.
The car manufacturers all certify their vehicles against a small set of tyres. That's a fact.
Its a necessity because choice of tyres touches almost every part of the certification process ranging from fuel economy figures to NVH (Noise, Vibration and Harshness) specs and parameters and many many other things.
Look inside your fuel-cap flap, you'll typically find a label there showing you a list of tyre specifications, of which maybe only one or two are actually certified by the manufacturer for your exact car model. The should of course also normally be found in the owners manual too.
In addition, the higher up the car spectrum you go, the tighter the definitions become. For example, the likes of Porsche actually do name precise brand and model for tyres.
Sure you can go off-piste with your tyre selection. But the manufacturer will likely take great delight at voiding your warranty. And your insurance might have a thing or two to say too since you are going against manufacturers guidelines. Finally of course the on-board computer calibration will be all off too.
