Polestar 3 tyres
The Polestar 3 leaves the factory on 255/50 R20 and 265/40 R22 and 265/45 R21 depending on wheel size, and the 255/50 R20 109V XL below is the one most owners are replacing. XL is not optional here; it is what the car was type approved on. It is staggered: a 255 section at the front and a 285 at the back, so the two can never be swapped across axles and the rear goes first. The Audi Q6 e-tron takes the same size.

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.
What changes on this car
The Polestar 3 is staggered on all three wheel sizes and XL on every corner, with a V rating throughout in both the UK and US listings.
Its 20 and 21 inch pairs are identical to the Volvo EX90's, which shares its SPA2 platform. The 22 inch is where they part: the Polestar's 295/35 R22 rear is listed as a 108 XL in both markets.
The 22 inch rear has about 103 mm of sidewall, the least on the car, while the 20 inch rear, 285/45 R20 112V, carries the most load at 1,120 kg.

Every figure here comes from one tyre 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.

Common questions
- What size tyres does the Polestar 3 take?
- It runs 255/50 R20 and 265/40 R22 and 265/45 R21. The exact fitment for your car is on On the driver's door jamb, on the B-pillar.
- Can I fit a cheaper tyre to a Polestar 3?
- Only at 255/50 R20 109V XL or better. That is the figure to hold: a tyre below the load index, the speed rating or the construction class is not a cheaper one, it is the wrong one.
