The 2023 Polestar 2 sits in the modern EV sport-sedan space with a design brief that blends Scandinavian restraint, everyday usability, and sharp road manners. Tire choice matters more than usual on a vehicle like this because wheel diameter, sidewall height, and overall stance all play a visible role in how the car drives and presents itself. The 2023 Polestar 2 uses radial tires, with fitments in 245/45R19, 245/40R20, and 245/35R21 depending on configuration. Available choices also vary by series and sidewall treatment, including blackwall, raised white letter, and redline options. The key is matching the exact wheel setup first, then choosing the tire character that suits your use and appearance goals.
Which Tire Size Is Right for The 2023 Polestar 2
Three tire sizes apply to the 2023 Polestar 2, and the right one depends first on confirming the exact sub-model and wheel diameter. The BST Edition cars use a different 21-inch fitment than the Base Front and Base Rear configurations, which are associated with 19-inch or 20-inch wheel setups. Once that is settled, the next decision becomes tire series, sidewall style, and the kind of road-use character you want from the available radial choices.
245/35R21 is a metric radial size in which 245 identifies nominal section width in millimeters, 35 is the aspect ratio, R denotes radial construction, and 21 is the wheel diameter in inches. On the 2023 Polestar 2, this size is tied to the BST Edition configurations and represents the lowest-profile fitment used here. Its dimensions keep overall diameter close to the other Polestar 2 sizes while using a much larger wheel. This size should be chosen only after confirming the vehicle's actual 21-inch wheel setup, since wheel diameter is the first fitment checkpoint.
245/40R20 is a metric radial size with a 245-millimeter nominal section width, a 40-series profile, and a 20-inch rim diameter. For the 2023 Polestar 2, it is one of the primary fitments used on Base Front and Base Rear configurations, making wheel confirmation especially important before selection. Available choices in this size include BFGoodrich, Nitto, and Pro-Trac, with blackwall, raised white letter, and redline sidewall treatments across several tire series. It is the right size to evaluate when the car is equipped with 20-inch wheels and you want meaningful choice within that setup.
245/45R19 is a metric radial size where 245 is the nominal section width in millimeters, 45 is the aspect ratio, and 19 indicates the wheel diameter in inches. On the 2023 Polestar 2, this is one of the primary sizes associated with Base Front and Base Rear applications, so it belongs to cars running the 19-inch wheel package rather than the larger-wheel alternatives. Product choices in this size come from BFGoodrich and Nitto and are centered on blackwall radial designs in several series. It is the size to consider after verifying a 19-inch wheel, especially if the goal is to stay with the standard sidewall presentation used by the available offerings.
Sub-model fitment matters on the 2023 Polestar 2 because the BST Edition cars use a different wheel and tire setup than the Base Front and Base Rear configurations. Identifying the exact sub-model is the quickest way to narrow the correct tire size before comparing brands, sidewall styles, or tire series.

2023 Polestar 2 BST Edition 230
The 2023 Polestar 2 BST Edition 230 uses the 245/35R21 radial fitment, which places it on the 21-inch wheel setup rather than the 19-inch or 20-inch alternatives. Tire selection here starts with confirming that larger wheel diameter, then choosing a tire that matches the intended road use and presentation of the car.
The 2023 Polestar 2 BST Edition 270 also uses the 245/35R21 radial size, so its fitment path is centered on the same low-profile 21-inch arrangement. That makes wheel verification essential before shopping, especially on any car that may have had wheels changed after delivery.
The 2023 Polestar 2 Base Front is associated with 245/40R20 and 245/45R19 radial tire sizes, so wheel diameter must be confirmed before narrowing the correct fitment. Once the wheel is identified, selection becomes a matter of comparing the available brands, tire series, and sidewall treatments within that exact size.
The 2023 Polestar 2 Base Rear shares the same two primary size paths, 245/40R20 and 245/45R19, making the wheel setup the key starting point. After that, the practical choice is between the product lines offered in the correct size, with attention to sidewall style and rim-width compatibility where stated.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

Tire Size & Fitment
What tire size fits a 2023 Polestar 2?
The 2023 Polestar 2 uses three primary tire sizes: 245/35R21, 245/40R20, and 245/45R19. All three are radial sizes, but they do not apply across every configuration. The BST Edition 230 and BST Edition 270 use 245/35R21, while Base Front and Base Rear configurations are associated with 245/40R20 and 245/45R19.
The practical first step is confirming the actual wheel diameter on the car before choosing a tire. A Polestar 2 with 19-inch wheels needs a different fitment path than one equipped with 20-inch or 21-inch wheels, and any aftermarket wheel change should be checked carefully before selecting a replacement tire.
What size rim does a 2023 Polestar 2 use?
The 2023 Polestar 2 appears with 19-inch, 20-inch, and 21-inch rim diameters depending on configuration. The 245/45R19 size corresponds to a 19-inch rim, 245/40R20 corresponds to a 20-inch rim, and 245/35R21 corresponds to a 21-inch rim. Matching tire size to wheel diameter is mandatory.
Rim diameter is the quickest way to narrow the correct fitment, especially on a model with multiple wheel packages. It is also worth checking wheel width when product specifications include a recommended range, since a tire can share the right diameter but still need confirmation that the wheel width is appropriate.
Do all 2023 Polestar 2 sub-models use the same tire size?
No. The 2023 Polestar 2 has sub-model variation in tire size. BST Edition 230 and BST Edition 270 use 245/35R21, while Base Front and Base Rear configurations are associated with 245/40R20 and 245/45R19. That means the correct tire size depends on the exact version of the car and its wheel setup.
This matters because the sidewall profile changes with each wheel diameter even though the nominal width remains 245 millimeters across all three sizes. A buyer should confirm the sub-model, then verify the actual wheel installed on the car, especially if the vehicle has been modified or if seasonal wheel sets are part of its current setup.
Choosing the Right Tire
What should I consider when choosing a 245/40R20 tire for a 2023 Polestar 2?
A 245/40R20 tire for a 2023 Polestar 2 should first match the car's 20-inch wheel setup, then be compared by construction details, tire series, sidewall treatment, and wheel-width suitability. In this size, available choices include BFGoodrich, Nitto, and Pro-Trac products, with blackwall, raised white letter, and redline presentations depending on the tire.
The right choice depends on how the car is used and how the owner wants it to look. Some buyers will prefer a more understated blackwall appearance, while others may want a more expressive sidewall style. Where rim-width guidance is stated, checking that against the actual wheel helps narrow the appropriate product more confidently.
What sidewall styles are available for 2023 Polestar 2 tires?
Sidewall style depends on the exact tire size. In 245/40R20, the available sidewall treatments include blackwall, raised white letter, and redline. In 245/45R19, the available products are centered on blackwall designs. That means sidewall appearance choice is broader on the 20-inch fitment than on the 19-inch fitment.
Appearance can be a major part of tire selection on a modern performance-oriented car, especially when wheel design leaves a lot of the sidewall visible. Matching the sidewall style to the vehicle's overall presentation is useful, but it still comes after confirming the correct wheel diameter and selecting the size that belongs on the car.
What brands offer tires for the 2023 Polestar 2?
The available 2023 Polestar 2 tire choices here come from BFGoodrich, Nitto, and Pro-Trac, depending on the size. BFGoodrich appears in both 245/40R20 and 245/45R19, Nitto appears in both of those sizes as well, and Pro-Trac appears in 245/40R20. Each brand is represented within radial product lines suited to the applicable wheel diameter.
Brand should be part of the selection process, but not the only factor. The correct tire size, the actual wheel diameter on the car, the sidewall style you want, and any published rim-width guidance all affect which product makes the most sense for a specific Polestar 2 setup.
Restoration & Appearance
Which tire should I choose for a period-style 2023 Polestar 2?
A period-style approach on a 2023 Polestar 2 is less about vintage construction and more about preserving the character of the wheel-and-tire package the car wears now. The right starting point is the exact original-size path for that setup: 245/35R21, 245/40R20, or 245/45R19 depending on sub-model and wheel diameter.
From there, appearance comes down to tire series and sidewall treatment rather than bias-ply versus radial decisions. A blackwall tire keeps a restrained modern look, while raised white letter or redline options in 245/40R20 create a more expressive presentation. Staying within the proper size family helps preserve the car's intended stance and proportions.
How does tire construction affect the appearance of a restored 2023 Polestar 2?
For the 2023 Polestar 2, construction is straightforward because the primary fitments are radial across all three sizes. That means appearance differences are shaped more by profile and sidewall design than by switching between bias-ply and radial construction. The 21-inch setup presents a notably lower-profile look than the 19-inch or 20-inch alternatives.
On a modern EV like this, wheel diameter and sidewall height strongly influence how finished the car looks. Choosing the correct tire size for the actual wheel package keeps the proportions consistent, and then sidewall treatment can fine-tune the visual effect without drifting away from the fitment the car is built around.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2023 Polestar 2?
Yes. Modifications can affect tire fitment on a 2023 Polestar 2 even when the nominal tire size looks close to stock. Aftermarket wheels, changes in wheel width, offset differences, suspension lowering, or body alterations can all change the space available around the tire. That matters on a vehicle offered with 19-inch, 20-inch, and 21-inch fitment paths.
A car that started life with one wheel package may no longer match its original fitment pattern after changes. Measuring the installed wheel diameter and width, then checking clearance at the fender, suspension, and steering lock positions, helps prevent choosing a tire that matches the label but not the actual setup.
What should I inspect before driving a 2023 Polestar 2 on new tires?
Before driving a 2023 Polestar 2 on new tires, confirm that the tire size matches the wheel diameter, the tires are inflated properly, and there is no interference at full steering lock or through normal suspension travel. It is also smart to verify that wheel hardware is torqued correctly and that the tires seat evenly on the rims.
A brief early inspection after the first miles can catch issues before they become larger problems. Look for rubbing marks, uneven air loss, vibration, or irregular contact wear, and keep an eye on sidewalls for cuts or bulges. These checks matter even more if the car has non-stock wheels or a recent suspension change.
How often should tires on a 2023 Polestar 2 be inspected?
Tires on a 2023 Polestar 2 should be inspected regularly rather than only when a problem appears. A quick visual check before longer drives is a good habit, with closer inspection for tread condition, sidewall damage, air pressure, and uneven wear at routine service intervals. Low-profile fitments especially benefit from frequent curb and impact checks.
Regular inspection helps catch developing issues such as punctures, shoulder wear, or sidewall damage before they affect road use. It is also worthwhile to recheck the tires any time the car hits a pothole hard, receives alignment work, or changes wheel sets, since those events can alter both condition and fitment.
