If wet braking matters most
Graded A for wet grip, and nothing else that fits is graded higher. Graded C for rolling resistance. EPREL registration 676712.

The Tesla Model S runs one fitment, 245/45 R19 98W. A standard load 98 rating is modest for an electric car and says something about where this one's curb weight sits. The BMW i5 takes the same size.
| Generation | Trim | Wheel | Tire size | Load index | Speed | Construction | Marking | Pressure |
|---|---|---|---|---|---|---|---|---|
| Current | Long Range (19in) | 19in | 245/45 R19 | 98 | W | SL | 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 tire.
On the 19 inch wheel the Model S runs one size on all four corners, 245/45 R19, so the tires can be rotated front to back and bought as a matched set of four.
Load index 98 is 750kg per tire. On a car that weighs more than two tonnes that leaves a margin, but not one worth spending on a tire rated any lower.
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 C for rolling resistance. EPREL registration 676712.
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 2584460.
Measured at 69 decibels, the quietest of the set. Graded A for wet grip, and nothing else that fits is graded higher. EPREL registration 2650388.
A winter tire, so a second set rather than a replacement for what is on the car now. Graded D for wet grip. Graded B for rolling resistance. EPREL registration 727667.
Rated below the speed this vehicle left the factory at, which is permitted for a winter tire and is why it carries a T or an R. The load index and the construction class still match. Do not exceed the tire's own rating while it is fitted.
Ordering is by the registered label figure, not by anything we think of them.
A high performance summer tire available in the Y rated sizes that heavy, fast electric cars are specified with.
Graded A for fuel efficiency in several of the sizes heavy electric cars use, which is a harder result on a two ton car than it looks.
An all-season tire for electric cars, which is a sensible default in a climate that rarely makes a full winter tire worth the second set of wheels.
A studless winter tire built for the weight and the rolling resistance demands of an electric car.
Rated below the speed this vehicle left the factory at, which is permitted for a winter tire and is why it carries a T or an R. The load index and the construction class still match. Do not exceed the tire's own rating while it is fitted.
A Korean-built summer tire that turns up as original equipment more often than its profile suggests, graded A for fuel efficiency.
A touring summer tire built with Bridgestone's Enliten construction, which cuts weight and rolling resistance across the range rather than in one model.
Every figure here comes from one tire maker's own fitment data, checked across different years or trims. That is a second look rather than a second opinion, so check the label on your door jamb before you buy.
