Speed Ratings for New Countryman Tires

[Uneripty]

Does anybody understand why Mini specifies Y-rated tires while the maximum speed of the C models is 130 MPH, for which V-rated tires would suffice? 130 is almost double the speed limit in the UK.

A higher speed rating enables a more durable and potentially safer tire; however, speed limitations vary among nations, such as Germany, and a business cannot alter the speed ratings for each nation.

Indeed, the maximum velocity of the C classic variant is much inferior than that of a V rating. What is the rationale for selecting Y-rated tires? It seems to be excessive to me.

I shared a screenshot of the speed codes in Italy; the Countryman C specifies a maximum speed of 212 km/h, perhaps due to safety considerations that preclude a lower measurement.

Moreover, during the homologation process, it is likely that all engines, including the JCW with a maximum velocity of 250 km/h, were taken into account to establish distinct speed codes.

I fully concur; a V grade is ideal. Why does Mini specify a Y rating? Significantly reduces the availability of tires; for instance, there are no All Season or Winter tyres with a Y grade. I will ultimately install All Season tires, despite their "only" V rating, but I cannot get why Mini equips vehicles with Y rated tyres instead of the superior and more economical V rated options.

I have just reviewed the tire specifications for the U25 Mini Countryman, where Mini enumerates all the tires compatible with the vehicle. I was pleasantly happy to see the Goodyear All Seasons Gen3 in the list, and rather astonished that Mini specifies a H speed rating! The tire is available with a V speed rating, leading me to conclude that the Goodyear tyre is an acceptable option for the vehicle.

Indeed, I was aware of the relationship; nevertheless, the issue is that, according to the Italian traffic code, all-season tyres must possess a speed rating that is not inferior to that of summer tires, which, in the case of the Mini Countryman, is Y. I am uncertain if the legislation differs in England... I would want Mini/BMW to avoid creating another issue; the concern of all-season tires does not pertain to me (17" rims...). I saw your response on a different thread.
