The 2015 Tesla Model S helped define the early modern luxury EV, combining long-range electric driving with full-size sedan space and unmistakably quick response. It sits at an interesting point in automotive history, where tire selection affects not only appearance and ride quality, but also how the car puts down its performance. For this exact Model S, fitment centers on three radial sizes: 245/45R19, 245/35R21, and 265/35R21, with size choice tied closely to wheel diameter and Sport Package front-versus-rear setup. That makes the key decision less about old-versus-new construction and more about confirming the exact wheel configuration, then choosing the right radial tire for road use, handling priorities, and overall presentation.
Which Tire Size Is Right for The 2015 Tesla Model S
The 2015 Tesla Model S uses three primary tire sizes, and the right one depends first on wheel diameter and whether the car has the Sport Package staggered 21-inch setup. Two sizes use 21-inch rims, while one uses a 19-inch rim. Before choosing a tire, confirm whether the car is on 19-inch wheels or on the 21-inch front-and-rear Sport Package combination.
245/35R21 is a metric radial size that uses a 245-millimeter nominal section width, a 35-series profile, and a 21-inch rim. On the 2015 Tesla Model S, this size serves as a low-profile radial fitment tied to the 21-inch wheel setup, including the Sport Package front position. Its dimensions point to a performance-oriented presentation with a shorter sidewall than the 19-inch alternative. This is the size to evaluate when the car is already equipped with 21-inch front wheels and the goal is to keep the correct front fitment for that wheel diameter.
245/45R19 is a metric radial size with a 245-millimeter nominal width, a 45-series aspect ratio, and a 19-inch rim diameter. For the 2015 Tesla Model S, it is the primary 19-inch fitment and appears on the Base model. Available choices in this size include BFGoodrich and Nitto products, all in blackwall form, with series such as g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2. This size deserves attention when the car remains on 19-inch wheels and the buyer wants to compare road-use character, series selection, and rim-width compatibility within the correct diameter.
265/35R21 is a metric radial size that combines a wider 265-millimeter nominal section width with a 35-series profile on a 21-inch rim. On the 2015 Tesla Model S, this size is used at the rear on the Sport Package staggered setup rather than across every configuration. Its wider footprint distinguishes it from the 245/35R21 front tire and makes position-specific fitment especially important. This is the size to verify when replacing rear tires on a Sport Package car, particularly if the vehicle has seen wheel, suspension, or alignment changes since new.
Sub-model fitment on the 2015 Tesla Model S is not one-size-fits-all. The Base model can use either the 19-inch or 21-inch front size, while the Sport Package setup matters because the front and rear tire sizes are different.

2015 Tesla Model S Base
The 2015 Tesla Model S Base uses either a 245/45R19 radial or a 245/35R21 radial, so wheel diameter is the first thing to confirm. Tire selection then becomes a matter of matching the car's actual 19-inch or 21-inch wheel setup rather than assuming every Base model uses the same rim size.
The front position on a 2015 Tesla Model S with Sport Package uses 245/35R21. That makes front-tire replacement straightforward once the package and wheel diameter are confirmed, but it should still be treated as a front-specific size within a staggered setup.
The rear position on a 2015 Tesla Model S with Sport Package uses 265/35R21, a wider 21-inch radial than the front. Rear replacement should focus on maintaining the proper staggered arrangement and checking that the car still has the intended rear wheel and suspension configuration.
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.

Current product choices focus on 245/45R19, where BFGoodrich and Nitto offer blackwall radial options across several performance-oriented series. The available tires also vary in rim-width specification, load figure, and overall product character, giving 19-inch Model S owners useful comparison points within the correct size.
Owners of a 2015 Tesla Model S usually need to sort out wheel diameter first, then confirm whether the car uses the standard 19-inch setup or the staggered 21-inch Sport Package arrangement. These FAQs cover size selection, radial fitment, product differences, appearance, and practical road-use checks.
Tire Size & Fitment
What tire size fits a 2015 Tesla Model S?
A 2015 Tesla Model S uses 245/45R19, 245/35R21, or 265/35R21 depending on wheel setup and sub-model position. The Base model uses either 245/45R19 or 245/35R21, while the Sport Package uses 245/35R21 in front and 265/35R21 in the rear.
The practical first step is confirming whether the car has 19-inch wheels or the 21-inch staggered arrangement. A Model S that has had wheel changes since new should be checked at the car itself, because front and rear size differences matter on Sport Package cars and rim diameter must match the tire.
What size rim does a 2015 Tesla Model S use?
The 2015 Tesla Model S uses either a 19-inch or 21-inch rim, depending on configuration. The 245/45R19 tire fits the 19-inch setup, while 245/35R21 and 265/35R21 are 21-inch sizes used on the larger-wheel arrangement.
Rim diameter is the most important fitment checkpoint because a 19-inch tire cannot be mounted on a 21-inch wheel, and vice versa. It also helps to confirm whether the car uses the same size at all four corners or a staggered front-and-rear combination before ordering replacement tires.
Do all 2015 Tesla Model S sub-models use the same tire size?
No. The 2015 Tesla Model S does not use one universal tire size across all covered sub-models. Base models can use either 245/45R19 or 245/35R21, and Sport Package cars use a staggered 21-inch setup with 245/35R21 in front and 265/35R21 in the rear.
That difference matters because the correct replacement depends on more than just the model name on the trunk. Checking the exact wheel package and whether the car has matching or staggered sizes avoids ordering a tire with the wrong diameter or using a front size where a wider rear tire belongs.
Choosing the Right Tire
What should I consider when choosing a 245/45R19 tire for a 2015 Tesla Model S?
Start with the correct 245/45R19 size, then compare the available radial choices by tire series, brand, rim-width specification, and load details. For this Model S size, BFGoodrich and Nitto options are available, including g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2.
The next step is matching the tire to how the car is used. A Model S driven regularly may call for different priorities than one used mainly for fair-weather trips, and wheel width should be confirmed before narrowing the field between otherwise correct 19-inch blackwall options.
What sidewall styles are available for 2015 Tesla Model S tires?
The available 245/45R19 product choices for a 2015 Tesla Model S are blackwall radials. That gives the car a clean modern appearance consistent with the Model S design language rather than a vintage sidewall treatment such as a whitewall or redline.
Sidewall style is still worth noting because it affects the car's visual character even when the size is correct. Buyers replacing only two tires often want to keep the overall appearance consistent from corner to corner, especially on a contemporary sedan where mismatched sidewall presentation is easy to spot.
What brands offer tires for the 2015 Tesla Model S?
Available 245/45R19 tires for the 2015 Tesla Model S include products from BFGoodrich and Nitto. BFGoodrich appears in more than one series, while Nitto is represented by the NT555 G2, giving 19-inch owners a few distinct radial choices within the same basic fitment.
Brand alone should not make the decision. Comparing the exact tire series, the intended use of the car, and the wheel's width specification is more helpful than chasing a name by itself, especially when replacing tires on a Model S that may already have non-original wheels or mixed prior tire history.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2015 Tesla Model S?
Yes. Wheel changes, offset differences, suspension lowering, alignment changes, and body modifications can all affect tire fitment on a 2015 Tesla Model S. Those changes matter even when the tire size itself is correct, because the car may no longer sit or steer exactly like a stock example.
A modified Model S should be checked for wheel diameter, wheel width, inner clearance, and fender clearance before replacement tires are chosen. Staggered 21-inch setups deserve extra care, since using the right front and rear sizes still does not guarantee enough room if the wheel or suspension package has been altered.
What should I inspect before driving a 2015 Tesla Model S on new tires?
Check inflation pressure, wheel condition, valve stems, tread-to-body clearance, and any signs that the old tires were wearing unevenly. It is also smart to confirm that the new tires match the car's actual wheel diameter and, on Sport Package cars, that the front and rear sizes have not been mixed.
A quick road-use inspection should also include looking over suspension and steering condition, since fresh tires cannot correct underlying hardware issues. Uneven wear, vibration, or pulling after installation often points to alignment or wheel problems that should be addressed before putting serious miles on the car.
What should I check before a longer drive in a 2015 Tesla Model S?
Before a longer drive, verify tire pressures, inspect tread and sidewalls for cuts or bulges, and make sure there is no slow air loss. On a 2015 Tesla Model S, it also helps to confirm that all four tires match the intended wheel setup, especially if the car uses staggered 21-inch sizes.
Longer trips are a good time to catch issues that short local drives may hide. Looking for irregular wear, checking torque on the wheels after recent tire service, and making sure there is no rubbing at full steering lock can prevent trouble once the car is farther from home.
