The 2020 Porsche Taycan brought Porsche performance into the electric era without losing the brand’s emphasis on precise road manners and purposeful stance. Even at this early point in the model’s history, tire selection plays a major role because Taycan fitment changes by trim, wheel package, and axle position. This car uses staggered radial tire sizing, with 19-inch, 20-inch, and 21-inch combinations appearing across the 4S, Turbo, and Turbo S. Available choices within the covered fitments include blackwall, redline, and raised white letter styles in 245/45R20. The key is matching the exact front or rear size to the car’s wheel setup before comparing appearance, series, or road-use priorities.
Which Tire Size Is Right for The 2020 Porsche Taycan
The 2020 Porsche Taycan uses six primary tire sizes, and the right choice depends first on the exact sub-model, wheel option, and whether you are selecting for the front or rear axle. These are all radial fitments, but they span 19-inch, 20-inch, and 21-inch rims, so confirming wheel diameter is just as important as identifying the correct Taycan configuration.
245/45R20 is a modern metric radial size with a 245 millimeter section width, a 45-series aspect ratio, and fitment on a 20-inch rim. On the 2020 Porsche Taycan, this size is used as a front fitment in certain configurations, so it needs to be matched to the correct axle and wheel package. Available choices include BFGoodrich, Nitto, and Pro-Trac products, with blackwall, redline, and raised white letter sidewall treatments across several tire series. This size is the one to evaluate when your Taycan carries the 20-inch front setup and appearance choice matters alongside basic fitment.
285/40R20 is a modern metric radial size that uses a 285 millimeter section width, a 40-series profile, and a 20-inch rim diameter. On the 2020 Porsche Taycan, it serves as a rear fitment in certain 20-inch staggered setups, which means it is paired with a different front size rather than used all around. Its role is part of the vehicle’s front-to-rear tire balance, so it should be selected only after confirming the exact Taycan model and axle position. Buyers looking at 20-inch packages should treat this as the rear half of a matched fitment plan.
Fit(s): 4S (21 Inch Option) Front, Turbo (21 Inch Option) Front, and Turbo S Front
Construction: Radial|Rim: 21 in
265/35R21 is a metric radial tire size with a 265 millimeter section width, a 35-series aspect ratio, and fitment on a 21-inch wheel. For the 2020 Porsche Taycan, this size appears as a front tire on certain 21-inch-option 4S models and on higher-performance Turbo and Turbo S front applications. Its lower-profile layout reflects a different wheel package than the 19-inch and 20-inch setups, so wheel diameter and axle position need to be verified before selection. This is the front size to consider when the car is equipped with the larger 21-inch staggered arrangement.
Fit(s): 4S (21 Inch Option) Rear, Turbo (21 Inch Option) Rear, and Turbo S Rear
Construction: Radial|Rim: 21 in
305/30R21 is a modern metric radial size using a 305 millimeter section width, a 30-series profile, and a 21-inch rim diameter. On the 2020 Porsche Taycan, it is used as the rear size in the 21-inch staggered fitments paired with a narrower front tire. That makes it a configuration-specific rear application rather than a general Taycan tire size, and it should be matched carefully to the proper front partner and wheel package. Owners with 21-inch cars should confirm both sub-model and axle before comparing any product choices in this size.
225/55R19 is a metric radial tire size with a 225 millimeter section width, a 55-series aspect ratio, and fitment on a 19-inch wheel. For the 2020 Porsche Taycan, this size is used as the front tire on the standard 4S setup rather than on the optional larger wheel packages. Its profile and rim diameter place it in a different fitment family from the 20-inch and 21-inch combinations, so buyers should not select it by model name alone. This is the size to verify when a Taycan 4S remains on its 19-inch front wheel arrangement.
275/45R19 is a modern metric radial with a 275 millimeter section width, a 45-series profile, and a 19-inch rim diameter. On the 2020 Porsche Taycan, it functions as the rear tire in the 19-inch staggered setup associated with the 4S. Because the Taycan uses different front and rear sizes in this arrangement, this tire should be chosen only as the rear component of that specific package. It is the correct size to examine when the car is a 19-inch 4S rear application and the goal is preserving the proper staggered relationship.
Tire fitment on the 2020 Porsche Taycan varies by sub-model, wheel option, and axle position rather than following one universal size across the range. Checking the exact 4S, Turbo, or Turbo S setup is essential, especially because the car uses staggered front-and-rear sizing and more than one rim diameter.

2020 Porsche Taycan 4S (20 Inch Option) Front
The 2020 Porsche Taycan 4S with the 20-inch option uses a dedicated front radial fitment that belongs to a staggered setup. Tire selection here starts with confirming the 20-inch front wheel package, then comparing available tire series and sidewall treatments within the correct size.
The 2020 Porsche Taycan 4S with the 20-inch option uses a separate rear radial size rather than matching the front tire. That makes rear fitment just as important to verify as front fitment, especially when maintaining the intended staggered wheel-and-tire arrangement.
The 2020 Porsche Taycan 4S with the 21-inch option uses a distinct front radial size tied specifically to the larger wheel package. Buyers should confirm that the car is on the 21-inch setup before comparing tires, since the 19-inch and 20-inch Taycan fitments use different dimensions.
The 2020 Porsche Taycan 4S with the 21-inch option carries its own rear radial size as part of a staggered front-and-rear combination. Choosing the right tire means matching the rear fitment to the 21-inch wheel package and keeping the axle-specific sizing relationship intact.
The standard 2020 Porsche Taycan 4S front fitment uses a 19-inch radial tire, making it different from both available upgrade wheel packages. This front application should be confirmed before selection so the tire matches the original wheel diameter and intended axle position.
The standard 2020 Porsche Taycan 4S rear fitment uses a separate 19-inch radial size paired with the 19-inch front tire. Tire choice here should stay focused on the correct rear application, since the Taycan’s staggered setup is not interchangeable from front to rear.
The 2020 Porsche Taycan Turbo with the 21-inch option uses a dedicated front radial tire size shared with certain other 21-inch Taycan configurations. The important step is confirming that the car is on the 21-inch front setup before evaluating any tire selection within that size.
The 2020 Porsche Taycan Turbo with the 21-inch option uses its own rear radial fitment to complete the staggered package. Buyers should verify the 21-inch rear wheel arrangement and select by axle position, not simply by Taycan model name alone.
The standard 2020 Porsche Taycan Turbo front fitment uses a 20-inch radial size rather than the 21-inch optional setup. That makes wheel confirmation essential before selection, especially if the car has changed hands or has been altered from its original wheel package.
The standard 2020 Porsche Taycan Turbo rear fitment uses a different 20-inch radial size from the front, continuing the Taycan’s staggered layout. Correct tire choice depends on matching the rear axle and wheel diameter first, then comparing the available products within that size.
The 2020 Porsche Taycan Turbo S front application uses a 21-inch radial tire that belongs to the larger staggered performance-oriented setup. Tire selection should begin with confirming that exact front wheel diameter, since the Taycan range also includes smaller 19-inch and 20-inch combinations.
The 2020 Porsche Taycan Turbo S rear application uses a dedicated 21-inch radial size paired with a different front tire. Owners should treat this as an axle-specific fitment decision and verify both wheel size and rear placement before comparing tire options.
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 2020 Porsche Taycan?
The 2020 Porsche Taycan does not use one universal tire size across the model range. Primary fitments include 225/55R19 and 275/45R19, 245/45R20 and 285/40R20, plus 265/35R21 and 305/30R21, all in radial construction and used in staggered front-and-rear combinations.
The right choice depends on the exact Taycan sub-model, wheel option, and axle position. A 4S on 19-inch wheels uses a different setup than a Turbo or Turbo S, and front and rear sizes are not interchangeable. Start by confirming the wheel diameter on the car, then match the tire to the correct front or rear location.
What size rim does a 2020 Porsche Taycan use?
The 2020 Porsche Taycan uses 19-inch, 20-inch, and 21-inch rim diameters depending on sub-model and wheel package. The 4S appears in 19-inch standard form and with 20-inch or 21-inch options, while Turbo and Turbo S applications move through 20-inch and 21-inch staggered combinations.
Rim diameter is the first thing to verify before choosing tires because the Taycan’s size range spans three distinct wheel diameters. The tire code confirms that measurement in the last number, such as 19, 20, or 21. A quick wheel check matters even more on cars that may have been upgraded or changed from their original wheel package.
Why does the 2020 Porsche Taycan have more than one tire size?
The 2020 Porsche Taycan has more than one tire size because fitment changes by trim level, optional wheel package, and front-versus-rear position. It uses staggered setups, so the front axle carries a different size from the rear, and those sizes also change as the car moves between 19-inch, 20-inch, and 21-inch wheels.
That means selection should begin with the exact configuration on the car rather than the Taycan name alone. A 4S with standard wheels, a 4S with a 21-inch option, and a Turbo S do not all share the same tires. Confirm the sub-model and wheel package first, then match the tire to the correct axle.
Choosing the Right Tire
What should I consider when choosing a 245/45R20 tire for a 2020 Porsche Taycan?
A 245/45R20 tire for a 2020 Porsche Taycan should first match the correct front 20-inch application. After that, compare the available radial choices by brand, tire series, sidewall style, and any rim-width or load details that matter for the wheel and intended use.
This size includes blackwall options from BFGoodrich and Nitto, along with Pro-Trac choices in redline and raised white letter form. That gives the buyer a meaningful appearance decision as well as a fitment decision. It also helps to confirm the actual wheel width on the car before narrowing the field within this 20-inch size.
What sidewall styles are available for 2020 Porsche Taycan tires?
Within the available 245/45R20 fitment for the 2020 Porsche Taycan, sidewall styles include blackwall, redline, and RWL, which is raised white letter. Those choices appear across radial tires and give this size a wider appearance range than a purely modern blackwall-only selection.
The practical difference is mostly visual, so the right choice depends on how you want the car to present itself. Blackwall keeps a cleaner modern look, while redline and raised white letter options create a more distinctive custom or enthusiast-oriented appearance. Sidewall style should always come after confirming the exact front 20-inch Taycan fitment.
What brands offer tires for the 2020 Porsche Taycan?
Available tires for the covered 2020 Porsche Taycan fitment include BFGoodrich, Nitto, and Pro-Trac in 245/45R20. These are all radial products, but they differ by tire series and sidewall treatment rather than representing one uniform type of replacement.
Brand selection works best when treated as part of a larger fitment decision. Once the wheel diameter and axle position are confirmed, compare the available series, sidewall appearance, and wheel-compatibility details that matter for your setup. That approach is more useful than choosing by brand name alone on a multi-fitment vehicle like the Taycan.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 Porsche Taycan?
Yes, modifications can affect tire fitment on a 2020 Porsche Taycan. Aftermarket wheels, changes in wheel width, offset differences, suspension alterations, or ride-height changes can all influence whether the intended front or rear size still has the right clearance and wheel compatibility.
That matters even more on the Taycan because it already uses staggered sizing and multiple rim diameters across the range. Any car that has been altered should be checked for steering clearance, inner and outer fender space, and the actual wheel dimensions before selecting tires. Matching the tire size by model year alone is not enough once modifications enter the picture.
What should I inspect before driving a 2020 Porsche Taycan on new tires?
Before driving a 2020 Porsche Taycan on new tires, inspect the wheel diameter, confirm that each tire is mounted in the correct front or rear position, and check inflation pressure, tread condition, and sidewalls for any cuts, bulges, or shipping damage. Lug torque and valve condition also deserve a quick review.
A short road check is worthwhile because the Taycan’s staggered setup makes front-to-rear placement especially important. Listen for rubbing, watch for vibration, and verify that the tires clear suspension and bodywork through normal steering travel. On any recently fitted set, rechecking pressure and general condition after the first drive is a sound habit.
What should I check before a longer drive in a 2020 Porsche Taycan?
Before a longer drive in a 2020 Porsche Taycan, confirm that the car has the correct front and rear tire sizes for its wheel package and that all four tires are in good condition. Pressure, tread depth, visible sidewall condition, and any signs of uneven wear should be reviewed before setting out.
Longer trips also make it worth checking for slow air loss and verifying that no wheel or suspension changes have introduced clearance issues. On a Taycan with optional or replacement wheels, a final look at tire-to-fender and tire-to-suspension space can prevent trouble on the road. A staggered electric performance car rewards careful fitment checks before mileage adds up.
