Porsche Taycan tires
The Porsche Taycan leaves the factory on 225/55 R19 and 245/40 R21 and 245/45 R20 and 265/35 R21 depending on wheel size, and the 225/55 R19 103Y 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 225 section at the front and a 275 at the back, so the two can never be swapped across axles and the rear goes first. The Audi A6 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 tire.
What changes on this car
The 2025 update added a second, narrower 21in pairing, 245/40 front and 285/35 rear, alongside the original 265/35 and 305/30. Porsche lists them on different rim widths, so the two sets are not interchangeable.
The Turbo GT is left out of this page: Porsche lists its 21in tires as 265/35 ZR 21 (101Y) and 305/30 ZR 21 (104Y), a rating above 300 km/h that cannot be shown here. Michelin lists the Turbo S Cross Turismo's 255/40 and 295/35 R20 option the same way, so it is also left out.
Porsche approves H-rated all-season and V-rated winter tires in the same sizes, and its 21in winter pair is listed at a higher load index, 103 and 107, than the summer one.
Every fitment is staggered, by 50 mm on the 19in and 40 mm on everything larger. The 19in, which Porsche does not approve for the Turbo, Turbo S or GTS, has the deepest sidewall at about 124 mm on the front.
No tires listed against this fitment yet. Product specifications are published from each manufacturer's own data and that work is not finished for 225/55 R19. Match or exceed every figure in the table above and you cannot go far wrong.

Including the manufacturer's own published figure. Neither source is standing next to your vehicle, which is why the placard still wins.

Common questions
- What size tires does the Porsche Taycan take?
- It runs 225/55 R19 and 245/40 R21 and 245/45 R20 and 265/35 R21. The exact fitment for your car is on On the driver's door jamb, on the B-pillar.
- Can I fit a cheaper tire to a Porsche Taycan?
- Only at 225/55 R19 103Y XL or better. That is the figure to hold: a tire below the load index, the speed rating or the construction class is not a cheaper one, it is the wrong one.
