No. Given what you have paid for the car. Every aspect of the car's performance goes through the tyres - braking, accelerating, cornering, etc. They will also last much longer than the cheaper makes and be safer in the wet. I am experimenting with Avons and smaller wheels at the moment but on my set of Rays I have 050As....but if I was starting again now I would have the Michelins.
