The 2021 Polestar 2 entered the market as a sharply styled electric fastback that blended Scandinavian restraint with modern performance-minded packaging. For buyers focused on one exact car, tire choice is less about vintage authenticity and more about matching the vehicle’s wheel setup and intended road use. This model uses radial tires in two primary sizes, 245/45R19 and 245/40R20, so the first job is confirming which rim diameter is actually on the car. From there, the real comparison is among available brands, series, and sidewall treatments, including blackwall options along with raised white letter and redline styling in 20-inch fitment. That approach helps balance appearance, wheel compatibility, and day-to-day driving needs.
Which Tire Size Is Right for The 2021 Polestar 2
The 2021 Polestar 2 uses two primary tire sizes, and the difference comes down first to wheel diameter: 19-inch wheels take 245/45R19, while 20-inch wheels take 245/40R20. Both are radial metric sizes, so the key step is confirming the exact wheel package on the car before comparing brands, tire series, and sidewall presentation.
Fit(s): Launch Edition Front and Launch Edition Rear
Construction: Radial|Rim: 20 in
A 245/40R20 tire uses a 245-millimeter nominal section width, a 40-series aspect ratio, radial construction, and a 20-inch rim diameter. On the 2021 Polestar 2, this size belongs to cars equipped with 20-inch wheels, making wheel confirmation the first fitment step rather than visual guesswork. Available choices include BFGoodrich, Nitto, and Pro-Trac, with blackwall, raised white letter, and redline sidewall treatments represented across different tire series. This size is the right place to focus if the car already wears 20-inch rims and the goal is to compare modern radial options without changing wheel diameter.
Fit(s): Launch Edition Front and Launch Edition Rear
Construction: Radial|Rim: 19 in
A 245/45R19 tire keeps the same 245-millimeter nominal section width but uses a 45-series profile on a 19-inch rim. For the 2021 Polestar 2, this is the primary fitment for cars equipped with 19-inch wheels, so the practical question is matching the tire to the existing wheel rather than choosing between interchangeable primary sizes. Product selection in this size includes BFGoodrich and Nitto options, centered on blackwall radial designs in several performance-oriented series. It is the size to evaluate when the car retains its 19-inch setup and the buyer wants a straightforward modern radial replacement path.
Fitment is straightforward across the covered 2021 Polestar 2 Launch Edition front and rear positions because both use the same two primary tire-size options. What matters most is confirming whether the car is on 19-inch or 20-inch wheels before narrowing the tire selection.

2021 Polestar 2 Launch Edition Front
The 2021 Polestar 2 Launch Edition Front uses the same radial fitment choices seen across this application, with tire selection tied to either a 19-inch or 20-inch wheel setup. That means the buying decision centers on wheel diameter first, then comparing available brands, series, and sidewall styles within the matching size.
The 2021 Polestar 2 Launch Edition Rear follows the same tire-fitment pattern, using radial options matched to either 19-inch or 20-inch wheels. Tire selection is therefore more about verifying the actual wheel package on the car and choosing the preferred product character than sorting through different rear-only primary sizes.
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.
Best 2021 Polestar 2 Tires for Sale
Available 2021 Polestar 2 tire choices center on 245/40R20 and 245/45R19 radial fitments from BFGoodrich, Nitto, and Pro-Trac. The main differences to compare in the product grid are tire series, blackwall versus raised white letter or redline styling, and rim-width compatibility where stated.
Common 2021 Polestar 2 tire questions usually come down to the correct size for the car’s wheel package, how 19-inch and 20-inch fitments differ, and how to compare available radial tires by brand, series, appearance, and everyday road-use checks.
Tire Size & Fitment
What tire size fits a 2021 Polestar 2?
The 2021 Polestar 2 uses two primary tire sizes: 245/45R19 and 245/40R20. Both are radial metric sizes, and each one corresponds to a different wheel diameter rather than a different tire construction choice. That means the correct selection starts with the wheel package already on the car.
A 19-inch wheel takes 245/45R19, while a 20-inch wheel takes 245/40R20. Since both sizes are valid for this model, the practical next step is checking the actual wheel diameter on the vehicle before comparing brands or tread styles. That matters especially on cars that may have had wheel changes after delivery.
What size rim does a 2021 Polestar 2 use?
A 2021 Polestar 2 uses either a 19-inch or 20-inch rim, depending on the tire size fitted to the car. The 245/45R19 size belongs on a 19-inch wheel, while the 245/40R20 size belongs on a 20-inch wheel. Both fitments use radial construction.
Rim diameter is the first thing to confirm before selecting tires because the two primary sizes are not meant for the same wheel. After diameter is verified, rim-width compatibility is also worth checking against the tire being considered, especially if the car has aftermarket wheels or a wheel package different from its current tires.
Do all 2021 Polestar 2 sub-models use the same tire size?
The covered 2021 Polestar 2 Launch Edition front and rear applications share the same two primary tire-size choices: 245/45R19 and 245/40R20. That means fitment stays consistent across those sub-model entries, with the real distinction being the wheel diameter installed on the individual car.
Because both sub-model entries allow the same pair of sizes, the buying decision is less about trim level and more about verifying the actual wheels on the vehicle. Checking the sidewall of the existing tire or measuring the wheel diameter helps avoid selecting a 19-inch tire for a 20-inch rim, or the reverse.
Choosing the Right Tire
What should I consider when choosing a 245/40R20 or 245/45R19 tire for a 2021 Polestar 2?
Start with the correct size for the wheel diameter on the car, since a 2021 Polestar 2 uses either 245/45R19 or 245/40R20. From there, compare the available radial tires by brand, tire series, sidewall style, and any stated rim-width or load details that matter to your setup.
A car used mainly for everyday road driving may call for a different product character than one built around a more customized appearance. It also helps to check whether the vehicle still has its original wheel package or has been changed since new, because an aftermarket wheel can affect which product specifications deserve the closest attention.
What sidewall styles are available for 2021 Polestar 2 tires?
Sidewall style depends on the size. In 245/40R20, available options include blackwall, raised white letter, and redline treatments. In 245/45R19, the available products shown here are blackwall radials, so appearance choices are more limited even though the size itself remains a correct primary fitment for 19-inch wheels.
That makes the 20-inch fitment more flexible for buyers who want a stronger visual statement, while the 19-inch fitment stays closer to a clean modern presentation. Sidewall style does not change the required wheel diameter, so appearance should be considered only after the correct size and the tire’s basic compatibility with the wheel are confirmed.
What brands offer tires for the 2021 Polestar 2?
Available tires for the 2021 Polestar 2 include offerings from BFGoodrich, Nitto, and Pro-Trac, depending on size. BFGoodrich appears in both 245/40R20 and 245/45R19, Nitto appears in both sizes as well, and Pro-Trac options are represented in the 20-inch fitment with distinct sidewall treatments.
Brand comparison is most useful after the wheel diameter is settled, because some choices are size-specific. Once that is clear, the decision can shift to tire series, sidewall appearance, and specification details such as rim-width range where stated. That approach keeps the selection process focused on compatible options rather than broad brand preference alone.
Restoration & Appearance
Which tire should I choose for a period-style 2021 Polestar 2?
A 2021 Polestar 2 is a modern EV, so the starting point is still the correct radial size for its wheel package: 245/45R19 for 19-inch wheels or 245/40R20 for 20-inch wheels. From there, a period-style or custom-leaning look comes more from sidewall presentation and tire series than from older construction types.
The 20-inch fitment offers the widest appearance range here, including blackwall, raised white letter, and redline options. A buyer aiming for a cleaner contemporary look may prefer blackwall, while a more expressive custom presentation may point toward the styled sidewalls. Wheel diameter still needs to match the tire exactly, regardless of appearance goals.
How does tire construction affect the appearance of a 2021 Polestar 2?
Construction does not create a bias-ply versus radial decision on the 2021 Polestar 2 because the primary fitments are radial. Appearance differences here come from sidewall treatment, tire series, and the visual effect of running the car on 19-inch versus 20-inch wheel-and-tire proportions rather than from switching construction types.
That means a buyer focused on presentation should look closely at blackwall, raised white letter, or redline availability within the correct size. The overall look can change noticeably even when section width stays the same. Keeping the proper tire size for the wheel is still essential so visual preference does not lead to an incorrect fitment choice.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2021 Polestar 2?
Yes, modifications can affect tire fitment on a 2021 Polestar 2 even when the tire size looks close on paper. Wheel changes, altered offsets, suspension adjustments, or body modifications can all influence how a 245/45R19 or 245/40R20 tire sits in the wheelwell and clears nearby components.
That is why the original fitment should be treated as a starting point, not a guarantee for every altered setup. Checking wheel diameter, wheel width, and available clearance at full steering lock and suspension travel is a smart step before changing tires. It is especially important when the car no longer wears its original wheel package.
What should I inspect before driving a 2021 Polestar 2 on new tires?
Before driving a 2021 Polestar 2 on new tires, inspect basic installation and condition items such as correct size, proper seating on the rim, valve condition, and inflation pressure appropriate to the vehicle setup. It also helps to check that there is no rubbing at the fender, suspension, or steering components.
A brief recheck after the first miles is worthwhile, especially if the car has different wheels than before or recently changed tire size within its accepted 19-inch or 20-inch fitment. Looking for air loss, unusual contact marks, vibration, or uneven stance can catch a problem early and helps confirm the tire matches the wheel correctly.
How often should tires on a 2021 Polestar 2 be inspected?
Tires on a 2021 Polestar 2 should be inspected regularly rather than only when tread looks low. Routine checks should include inflation pressure, visible tread wear, cuts, bulges, and sidewall damage. Even a newer vehicle benefits from frequent inspection because tire issues often appear gradually rather than all at once.
Monthly pressure and condition checks are a sensible habit, with an extra inspection before longer drives or after pothole impacts. Uneven wear can also point to alignment or suspension issues that affect how either 245/45R19 or 245/40R20 tires behave on the car. Catching those signs early helps protect both ride quality and tire life.
