Are there any performance benefits from using H-rated tyres over V-rated tyres on my Saab 9000?

I always fit replacement Michelin Energy 195/65 R15 Tyres on my old Saab 9000 CSE and have been asked whether I require H or V rated tyres. I do understand that 'V' is geared to higher speeds and, although recommended for the vehicle on the Michelin website, I am advised by my local tyre service that 'H' would be quite sufficient. I am happy to accept this advice, but am just interested in your view on whether V-rated might be either a) longer lasting or b) a more comfortable ride, or both, than H-rated? Perhaps the opposite is the case? The price difference is not too great. Perhaps one is more robust than the other so slightly less likely to fail in a 'stressed' situation?

No, the tyres have to be the speed rating originally specified for the car, otherwise you have to inform your insurer that you have fitted inferior tyres to the car. The speed rating is related to general performance, not merely speed alone.
