2024 Polestar Tire Fitment Guide

2024 Polestar vehicles use two tire sizes: 245/40R20 and 245/45R19, and both apply to the Polestar 2. The 245/40R20 mounts on a 20-inch wheel and the 245/45R19 mounts on a 19-inch wheel. Rim-width guidance is available for both sizes from products in each group, with 245/40R20 covering 8.0 to 9.5 inches and 245/45R19 covering 7.5 to 9.0 inches.

The practical takeaway is that year and make alone are not enough if you are replacing tires on a 2024 Polestar. You need to confirm whether your Polestar 2 is on 19-inch or 20-inch wheels before moving on to brand or performance preferences. Once wheel diameter is confirmed, you can compare the approved rim-width range, speed rating, and sidewall style options inside that specific size.

On a 2024 Polestar, 245/40R20 means the tire is 245 millimeters wide, has a 40-series aspect ratio, uses radial construction, and fits a 20-inch wheel. That is a modern metric radial size commonly seen on performance-oriented late-model vehicles. Within this size, speed ratings reach W and Y depending on the tire selected, and sidewall appearance can be either Blackwall or raised white letters.

That code matters because every part of it affects replacement fitment. A 20-inch tire cannot substitute for a 19-inch wheel, and the lower sidewall profile of a 40-series tire changes the visual stance compared with the taller 45-series alternative used on other Polestar 2 wheel packages. If your current tire shows 245/40R20 on the sidewall, stay with that size unless you are intentionally changing wheels and confirming the full package separately.

On a 2024 Polestar, 245/45R19 means the tire is 245 millimeters wide, has a 45-series aspect ratio, uses radial construction, and fits a 19-inch wheel. It keeps the same section width as the 20-inch fitment but pairs it with a taller sidewall and a smaller rim diameter. Products in this size carry W and Y speed ratings, with Blackwall styling across the available range.

For a buyer, the most important point is that 245/45R19 is tied to the 19-inch wheel package on the Polestar 2. It is not the same as the 245/40R20 fitment, even though both start with the same 245-millimeter width. Checking the sidewall on the car, or confirming the wheel diameter directly, is the simplest way to avoid mixing the two sizes.

For a 2024 Polestar, the choice between 245/40R20 and 245/45R19 is mainly a matter of matching the wheel diameter already on your Polestar 2. Both are modern radial sizes, but one fits a 20-inch wheel and the other fits a 19-inch wheel. This is not a bias-ply-versus-radial decision or a year-correct restoration choice; it is a wheel-package fitment decision.

Start by reading the tire sidewall currently on the car or measuring the wheel diameter directly. If your Polestar 2 uses 20-inch wheels, stay with 245/40R20; if it uses 19-inch wheels, stay with 245/45R19. After that, compare sidewall styling, speed rating, and approved rim-width range within the correct size rather than trying to choose between the two sizes as interchangeable options.

2024 Polestar tires are available in different sidewall presentations depending on size. The 245/40R20 size comes in both Blackwall and RWL form, while the 245/45R19 size is available in Blackwall only. Since the Polestar 2 is a contemporary premium EV, Blackwall styling is the most visually in-step with the car’s original modern design language.

Sidewall style is mostly an appearance decision once the correct size is confirmed. A Blackwall tire keeps the clean, understated look many Polestar owners prefer, while an RWL option gives the 20-inch fitment a more overt performance look. If your goal is to preserve the car’s stock visual character, Blackwall is the safer direction; if you want a more customized presentation, the 20-inch size opens that door.

2024 Polestar fitments are covered by BFGoodrich and Nitto in both sizes, with Pro-Trac also available in 245/40R20. BFGoodrich appears in each size through multiple performance-oriented radial offerings, while Nitto covers both the 19-inch and 20-inch applications as well. Brand availability is broader in the 20-inch size than in the 19-inch size.

That brand spread gives Polestar 2 owners room to prioritize different things inside the correct size, such as sidewall appearance, speed rating, or a preferred manufacturer. If you are replacing a matched set, it usually makes sense to compare all options within your existing wheel diameter first. If you are replacing a single damaged tire, consistency with the rest of the set becomes even more important.

For 2024 Polestar applications, 245/40R20 tires cover approved rim widths from 8.0 to 9.5 inches, and 245/45R19 tires cover approved rim widths from 7.5 to 9.0 inches. Those ranges come directly from products within each size family, so they are useful real-world guides for the Polestar 2 wheel packages associated with those tires.

Rim width matters because even the right tire size can behave poorly if mounted on a wheel outside the approved range. Before replacing tires on a 2024 Polestar, confirm both the wheel diameter and the actual wheel width. That is especially worthwhile if the car has aftermarket wheels, since the nominal tire size alone does not guarantee the wheel falls inside the proper mounting range.

The 2024 Polestar sizes here are modern radial fitments with no tube-type markings, and they align with contemporary tubeless passenger-car practice. The available 245/40R20 and 245/45R19 products use modern metric sizing and performance-oriented construction rather than vintage tube-type design. Nothing in these fitments suggests an inner-tube requirement.

Even so, tubeless fitment still depends on wheel condition and valve-stem integrity. If your Polestar 2 has damaged bead seats, bent wheels, or modified rims, those issues should be corrected before mounting replacement tires. For normal OE-style late-model wheels in sound condition, the focus should be on proper mounting, balancing, and inflation rather than tube selection.

A 2024 Polestar should be stored in a cool, dry space away from direct sunlight, electric motors that create ozone, and long exposure to standing moisture. Clean the tires before storage, keep them at the correct inflation pressure, and move the car periodically if it will sit for extended stretches. Modern radials generally tolerate storage better than older bias-ply designs, but they still age from environment and inactivity.

If your Polestar 2 will be parked for months at a time, occasional rolling helps reduce flat spotting and keeps the contact patch from taking a set. Owners who maintain collector or seasonal vehicles often use tire cradles or stands for long-term storage, but a clean indoor setting and regular pressure checks already make a meaningful difference. Storage habits affect ride quality and sidewall condition just as much as mileage does.

Tires on a 2024 Polestar should be judged by age as well as tread depth. A good rule is to begin close inspection and professional evaluation once tires reach about five to seven years old, with replacement becoming a serious consideration around the ten-year mark regardless of mileage. The DOT date code on the sidewall is the most reliable way to confirm a tire’s actual age.

That approach is especially important on low-mile collector or weekend-driven cars, where tires can look acceptable while the rubber has already hardened with time. EV torque and vehicle weight can also accelerate wear patterns if alignment or pressure drifts out of spec. A Polestar 2 that is driven infrequently still benefits from age-based tire decisions rather than waiting for the tread to wear out.

Tires on a 2024 Polestar deserve a quick inspection before every drive and a more thorough check before any longer outing. Look for cuts, bulges, punctures, sidewall cracking, uneven wear, and any loss of pressure. Because these are modern radial tubeless fitments, valve stems and bead sealing areas are also worth checking whenever the wheels are off the car.

Regular inspection matters because many tire problems show up gradually before they become obvious from behind the wheel. Uneven shoulder wear can point to alignment issues, while repeated pressure loss may signal a valve, wheel, or puncture problem rather than the tire itself. Catching those signs early protects ride quality, range, and overall confidence on the road.

A 2024 Polestar 2 belongs to a modern EV era in which radial tires are the normal original-equipment construction, and the fitments here reflect that with 245/45R19 and 245/40R20 radial sizes. There is no vintage-style construction choice to sort through for authenticity the way there would be on an older collector car. The main authenticity question is usually whether the car is still wearing the wheel diameter and overall appearance it was delivered with.

For owners who want to keep the car visually close to factory presentation, confirm the original wheel package and stay with the matching tire size and understated sidewall style. On a late-model Polestar, authenticity is more about preserving the intended modern look than recreating an obsolete construction type. If your car has changed hands or been modified, a Polestar specialist can help confirm the original wheel package from the VIN and build details.

Correct tire fitment does matter when a 2024 Polestar is shown, especially if the event values factory appearance and presentation. Judges and knowledgeable enthusiasts will notice obvious departures such as the wrong wheel diameter, an incorrect overall visual profile, or a sidewall style that clashes with the car’s contemporary design language. Because the Polestar 2 uses modern radial fitments, authenticity usually comes down to size, wheel package, and appearance rather than vintage construction details.

A Polestar prepared for display generally looks most coherent when the tire size matches the correct 19-inch or 20-inch wheel package and the sidewall treatment stays clean and modern. Small appearance choices can change the car’s personality more than many owners expect. If you are entering a marque-focused event, check the event’s judging philosophy first, since some will be more tolerant of tasteful substitutions than others.

For the 2024 Polestar, both BFGoodrich g-Force Comp 2 A/S and g-Force Phenom T/A appear in the 245/40R20 and 245/45R19 sizes, but they are not identical. In 245/40R20, the Comp 2 A/S carries a 99W rating and a 29-pound weight, while the Phenom T/A carries a 99Y rating, a 1,709-pound maximum load at 50 psi, and a 28.06-pound weight. In 245/45R19, the Comp 2 A/S is rated 98W at 29 pounds, while the Phenom T/A is rated 102Y with a 1,874-pound maximum load at 50 psi and a 29.26-pound weight.

That means a buyer comparing the two should look beyond brand name and focus on the exact size-level differences. The Phenom T/A carries the higher Y speed rating in both sizes and includes explicit load-and-pressure figures, while the Comp 2 A/S stays at a W rating in each application. If those distinctions matter for how you use your Polestar 2, compare them within your wheel diameter rather than assuming the two series are interchangeable in every detail.

Yes, the 2024 Polestar tire options here are modern radial tires with W- and Y-rated versions, making them appropriate for normal highway use when they are in good condition and correctly matched to the car’s wheel diameter. A W rating corresponds to 168 mph and a Y rating corresponds to 186 mph. Those ceilings are far beyond ordinary U.S. highway speeds, so real-world safety usually depends more on condition, inflation, alignment, and the car’s overall mechanical state than on absolute top-speed capability.

For practical driving, the more important question is whether the tires are the correct 19-inch or 20-inch fitment and whether they are wearing evenly. A high speed rating does not compensate for age cracking, underinflation, or a damaged wheel. If your Polestar 2 is used regularly, inspect the tires often and treat the speed rating as capacity information, not as a target.

Inflation pressure for a 2024 Polestar should follow the vehicle placard or owner’s manual first, because factory pressure targets are set around the car’s weight distribution and intended use. Tire-specific maximum figures appear on some products, such as 1,709 pounds at 50 psi for certain 245/40R20 applications and 1,874 pounds at 50 psi for certain 245/45R19 applications. Those figures describe the tire’s rated load at maximum pressure, not the everyday operating pressure you should automatically use.

The safest approach is to match the tire size to the correct wheel package, then use the carmaker’s recommended cold inflation pressure for routine driving. If you are comparing different tire models within the same size, do not transfer a maximum-pressure figure from one tire to another or from one size to another. Pressure affects ride, wear, and energy efficiency, so getting it right matters on an EV like the Polestar 2.

Before a longer trip in a 2024 Polestar, inspect all four tires for proper inflation, tread condition, punctures, cuts, bulges, and sidewall damage. Make sure the tires match the car’s actual wheel diameter, verify that wear is even across the tread, and check the valve stems for age or damage. It is also wise to inspect the spare or mobility kit situation so you know what roadside backup you actually have.

A longer drive is also the right time to think beyond the tires themselves. On a Polestar 2, wheel damage, alignment drift, or an unnoticed slow leak can affect both confidence and efficiency over distance. If anything looks questionable before departure, address it while the car is still in the garage rather than hoping the problem stays minor on the road.
