Kumho PS71
7 sizes, 215/50 R17 to 255/45 R20
Kumho Tire · Manufacturer material, used by permission
Graded A for fuel efficiency in several of the sizes heavy electric cars use, which is a harder result on a two tonne car than it looks. Good fit for a driver who wants range back and will accept a B for wet grip to get it.

Great Britain retained Regulation (EC) 1222/2009, so the label here uses the older A to G scales. Northern Ireland follows the current EU label, which runs A to E and carries a QR code.
What it is for
The A is the whole story here. Rolling resistance is the one tyre property that converts directly into miles on the display, and the top grade on a wide 19 inch fitment for a heavy car is not something many tyres manage. The B alongside it is the price: wet braking is a rung below the best in class, and on a heavy car that is a real trade rather than a rounding error. It is chosen as original equipment by manufacturers who set the balance the same way.
