If wet braking matters most
Graded A for wet grip, and nothing else that fits is graded higher. Graded B for rolling resistance. EPREL registration 2795263.

The Kia EV3 leaves the factory on 215/50 R19 and 215/60 R17 depending on wheel size, and the 215/60 R17 96H below is the one most owners are replacing. A standard load 96 rating is modest for an electric car and says something about where this one's kerb weight sits. The BYD Atto 2 takes the same size.
| Generation | Trim | Wheel | Tyre size | Load index | Speed | Construction | Marking | Pressure |
|---|---|---|---|---|---|---|---|---|
| Current | Air (17in) | 17in | 215/60 R17 | 96 | H | SL | none | see plate |
| Current | GT-Line and GT-Line S (19in) | 19in | 215/50 R19 | 97 | H | XL | none | see plate |
Your own placard is the authority. You will find it on the on the driver's door jamb, on the B-pillar. Where it disagrees with this page, it wins. Match or exceed the size, load index, speed rating and construction class it gives, and use its pressure figure rather than anything printed on the tyre.
The EV3 keeps the same 215 mm width on both of its common wheels. The 17 inch is standard load at 96, while the 19 inch is an XL tyre at 97, so a standard-load 215/50 R19 (index 93) is not a valid replacement on the GT-Line.
Both fitments are H rated, which is modest for an electric car of this size and reflects its city-crossover brief.
The AWD GT runs a separate 245/40 R20 size; neither Kia nor a tyre maker's selector gave its load index, so it is not listed here.
How these were chosen. Everything here already clears this vehicle's own load index, speed rating and construction class. Each heading is a question about use rather than a ranking. The whole method.
Graded A for wet grip, and nothing else that fits is graded higher. Graded B for rolling resistance. EPREL registration 2795263.
Graded A for rolling resistance, the best of anything here, and that is the figure that shows on the range display. Graded B for wet grip. EPREL registration 412158.
Measured at 71 decibels. Graded A for wet grip, and nothing else that fits is graded higher. EPREL registration 658810.

Ordering is by the registered label figure, not by anything we think of them.
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.
An efficiency-first summer tyre aimed squarely at range rather than at cornering.
Sumitomo's electric-car range at a price well below the flagships, with the load ratings heavy battery cars actually need.
Graded A for wet grip in the large sizes electric SUVs run, which is the grade worth paying for.
Continental's efficiency summer tyre in the sizes heavy electric cars actually use, available in some fitments with the ContiSilent foam liner.
A touring summer tyre built with Bridgestone's Enliten construction, which cuts weight and rolling resistance across the range rather than in one model.
Including the manufacturer's own published figure. Neither source is standing next to your vehicle, which is why the placard still wins.
