The Tesla Model Y leaves the factory on 255/40 R20 and 255/45 R19 depending on wheel size, and the 255/45 R19 104W XL below is the one most owners are replacing. XL is not optional here; it is what the car was type approved on. The Mercedes-Benz EQE takes the same size.
| Generation | Trim | Wheel | Tire size | Load index | Speed | Construction | Marking | Pressure |
|---|---|---|---|---|---|---|---|---|
| 2021 onwards | Long Range AWD | 19in Gemini | 255/45 R19 | 104 | W | XL | T1 | 42 psi |
| 2021 onwards | Performance | 20in Induction | 255/40 R20 | 101 | W | XL | T1 | 42 psi |
Your own placard is the authority. You will find it on the driver's door jamb, lower 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.
The 19 inch wheel is the sensible replacement size on a Model Y and the 20 inch is not, because the 20 costs range, rides harder and narrows the choice of tire to a handful of performance fitments.
Tesla's placard pressure of 42 psi is high for a car this size and it is deliberate: it is holding up a curb weight around two tons and it is buying back rolling resistance. Dropping it to what feels normal costs range and wears the shoulders.
Michelin publish 255/45R19 XL 104W for the 19 inch car and 255/40R20 XL 101W for the 20 inch, and the W rather than a Y is worth noticing: it means the touring and efficiency ranges are open to you, not just the performance ones.
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 B for wet grip. Graded A for rolling resistance, the best of anything here, and that is the figure that shows on the range display. Carries the T1 marking. EPREL registration 1974688.
Graded A for wet grip, and nothing else that fits is graded higher. Graded A for rolling resistance, the best of anything here, and that is the figure that shows on the range display. EPREL registration 2561730.
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 2462912.
Measured at 72 decibels. Graded B for wet grip. EPREL registration 558686.
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 727663.
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.
A studless winter tire built for the weight and the rolling resistance demands of an electric car.

Designed for electric cars from the ground up rather than adapted from a combustion tire, and the winner of the 2025 Auto Bild EV tire test.
A Korean-built summer tire that turns up as original equipment more often than its profile suggests, graded A for fuel efficiency.
Kumho's electric-car version of the Ecsta PS71, with its own tread and a casing built for the weight and instant torque of an EV.
A touring summer tire built with Bridgestone's Enliten construction, which cuts weight and rolling resistance across the range rather than in one model.
An efficiency-first summer tire aimed squarely at range rather than at cornering.
A performance summer tire built for heavy, fast electric cars, with an acoustic foam liner bonded inside the cavity.
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.
