1. After a little more than a week with my “boy” I noticed that my Michelin Primacy HP carries the index 91 W. So allowed up to a speed of 270 km/h. Isn’t that exaggerated? Couldn’t Volvo have saved? Wouldn’t an index of H (210) maximum V (240) have been enough? After all, the car is registered with a maximum of 210 km/h. 2. And then I wonder if Volvo has the tyres from home with gas (lower rolling resistance, filling does not escape as fast as air) or conventionally filled with air? SuFu unfortunately didn’t help any further. Thanks in advance.
