The 2018 Tesla Model S sits at an important point in modern performance sedan history, blending long-range electric driving with the kind of acceleration and wheel-and-tire sensitivity that makes fitment details matter. On this exact model, tire choice starts with three radial sizes: 245/45R19 for the standard 19-inch setup, plus 245/35R21 front and 265/35R21 rear for Sport Package staggered 21-inch fitment. That means the real decision is not just size, but also whether the car is on its 19-inch wheels or staggered 21s. For owners focused on road manners, appearance, and proper clearance, confirming the exact sub-model and wheel setup comes first.
Which Tire Size Is Right for The 2018 Tesla Model S
The 2018 Tesla Model S uses three primary tire sizes, and the right one depends first on the exact wheel setup. Standard fitment centers on 245/45R19 on a 19-inch rim, while Sport Package cars use a staggered 21-inch arrangement with 245/35R21 in front and 265/35R21 in the rear. Before choosing a tire, confirm whether the car is on 19-inch wheels or the 21-inch front-and-rear Sport Package configuration.
Fit(s): 100D, 100D w/Sport Pkg. Front, 75D, 75D w/Sport Pkg. Front, P100D, and P100D w/Sport Pkg. Front
Construction: Radial|Rim: 21 in
A 245/35R21 tire is a metric radial size with a 245 millimeter section width, a 35-series aspect ratio, and fitment for a 21-inch rim. On the 2018 Tesla Model S, this size serves the front position on Sport Package applications, so it should be viewed as part of a staggered setup rather than a universal replacement across every configuration. Its low-profile construction suits the larger-wheel layout used on those models. Choosing this size starts with confirming that the car actually uses the 21-inch front wheel arrangement and has not been changed to another wheel package.
A 245/45R19 tire uses a 245 millimeter section width, a 45-series profile, and a 19-inch rim diameter in modern radial format. This is the standard 19-inch tire size used across several 2018 Tesla Model S sub-models, making it the key fitment for owners who are not running the 21-inch Sport Package setup. Available choices in this size include BFGoodrich and Nitto products, with blackwall sidewalls and multiple performance-oriented series. The practical decision here is comparing tire character and wheel-width compatibility within the correct 19-inch fitment.
A 265/35R21 tire is a metric radial with a 265 millimeter section width, a 35-series profile, and a 21-inch rim diameter. On the 2018 Tesla Model S, this size is used at the rear on Sport Package applications, pairing with 245/35R21 in front as part of a staggered arrangement. Its role is specific, so it should not be treated as a stand-alone replacement for every Model S configuration. Before selecting this size, confirm the rear wheel diameter and make sure the car still retains the proper front-to-rear setup intended for the 21-inch package.
Sub-model fitment on the 2018 Tesla Model S varies by wheel package and by front or rear position on Sport Package cars. Checking the exact sub-model matters because some versions use the standard 19-inch setup, while others use a staggered 21-inch front-and-rear combination.

2018 Tesla Model S 100D
The 2018 Tesla Model S 100D uses either the standard 245/45R19 radial size or the 21-inch Sport Package setup. Tire selection starts with confirming which wheel package is actually on the car, since the correct replacement path changes completely between 19-inch and 21-inch fitment.
The front position on the 2018 Tesla Model S 100D w/Sport Pkg. uses the 245/35R21 radial size. That makes front-tire selection part of a staggered setup, so the buyer should match the front fitment carefully and keep the wheel diameter consistent with the rear arrangement.
The rear position on the 2018 Tesla Model S 100D w/Sport Pkg. uses 265/35R21. Rear tire selection should account for the staggered 21-inch layout, with attention to keeping the correct rear size rather than assuming the front and rear tires are interchangeable.
The 2018 Tesla Model S 75D uses either 245/45R19 in standard form or the 21-inch Sport Package configuration. Identifying the actual wheel setup is the first step, because the tire decision is different for a single-size 19-inch arrangement than for staggered 21-inch fitment.
The front tire size for the 2018 Tesla Model S 75D w/Sport Pkg. is 245/35R21. That points the buyer toward low-profile 21-inch front fitment, with the next step being confirmation that the wheel and the matching rear size remain part of the intended staggered package.
The 2018 Tesla Model S 75D w/Sport Pkg. uses 265/35R21 at the rear. Choosing a rear tire here means maintaining the proper staggered relationship with the 21-inch front size and checking that the car has not been changed to a non-stock wheel setup.
The 2018 Tesla Model S P100D can use the standard 245/45R19 size or the staggered 21-inch Sport Package configuration. Tire selection depends on confirming the current wheel package first, because that determines whether the car needs a 19-inch fitment or separate front-and-rear 21-inch sizes.
The front tire on the 2018 Tesla Model S P100D w/Sport Pkg. is 245/35R21. This size should be chosen as the front half of the staggered 21-inch setup, with attention to matching the wheel diameter and preserving the intended front-to-rear fitment balance.
The 2018 Tesla Model S P100D w/Sport Pkg. uses 265/35R21 at the rear. That rear-specific size matters because staggered setups depend on keeping the correct position-specific tire, especially if wheels, suspension height, or prior replacement choices have changed the car from stock.
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 2018 Tesla Model S Tires for Sale
Available 245/45R19 options for the 2018 Tesla Model S include BFGoodrich and Nitto radial tires in blackwall form. The product grid is most useful for comparing series, wheel-width compatibility, load-related specifications where stated, and the overall character of each 19-inch option.
These FAQs focus on the exact tire sizes used on the 2018 Tesla Model S, including 19-inch versus 21-inch fitment, staggered Sport Package sizing, product-selection differences, and the basic checks worth making before regular road use.
Tire Size & Fitment
What tire size fits a 2018 Tesla Model S?
The 2018 Tesla Model S uses three primary tire sizes: 245/45R19, 245/35R21, and 265/35R21. The 245/45R19 size is used on the standard 19-inch setup, while Sport Package applications use a staggered 21-inch arrangement with 245/35R21 in front and 265/35R21 in the rear.
The important next step is confirming which wheel package is actually on the car. A Model S wearing 19-inch wheels needs a different tire path than one equipped with 21-inch staggered wheels, and front and rear 21-inch positions should not be treated as the same size.
What size rim does a 2018 Tesla Model S use?
A 2018 Tesla Model S uses either a 19-inch or 21-inch rim, depending on the tire size and wheel package. The 245/45R19 tire fits a 19-inch rim, while both 245/35R21 and 265/35R21 are built for 21-inch rims.
Wheel diameter should be verified before looking at tread pattern or brand. It is also worth checking whether the car still has its intended wheel package, since prior owners may have changed wheels, and a staggered 21-inch setup adds the extra step of confirming front and rear fitment separately.
Why does the 2018 Tesla Model S have more than one tire size?
The 2018 Tesla Model S has more than one tire size because it was offered with different wheel packages. Standard applications use 245/45R19, while Sport Package versions use a staggered setup that places 245/35R21 on the front and 265/35R21 on the rear.
That means the correct tire is tied to the actual configuration on the car rather than the model name alone. Looking at the current wheel diameter and checking whether the car uses the Sport Package front-and-rear arrangement will prevent ordering a tire that matches the model but not the wheel setup.
Choosing the Right Tire
What should I consider when choosing a 245/45R19 tire for a 2018 Tesla Model S?
Start with the basics: correct size, 19-inch rim compatibility, and radial construction. Within 245/45R19, the available choices for the 2018 Tesla Model S include blackwall tires from BFGoodrich and Nitto, with series such as g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2.
After confirming size, compare the tire’s intended character and wheel-width compatibility. Some 245/45R19 options include stated rim-width ranges of 7.5 to 9 inches, which is useful when verifying the wheel already on the car. Load-related specifications and tire weight can also help narrow the choice for how the car is actually driven.
What sidewall styles are available for 2018 Tesla Model S tires?
The currently available 245/45R19 product choices for the 2018 Tesla Model S use a blackwall sidewall style. That keeps the appearance clean and modern, which suits the overall look of the Model S without introducing a period-style stripe or raised-letter presentation.
Sidewall style is still worth noting because it affects the visual impression of the car even when the tire size is correct. Once the wheel package is confirmed, the buyer can focus on series and specification differences within the available blackwall options rather than trying to choose between multiple cosmetic sidewall treatments.
What brands offer tires for the 2018 Tesla Model S?
For the 245/45R19 size used on the 19-inch 2018 Tesla Model S setup, available products include BFGoodrich and Nitto. BFGoodrich appears in more than one series, including g-Force Comp 2 AS and g-Force Phenom T/A, while Nitto is represented by the NT555 G2.
Brand alone is only part of the decision. It helps to compare the exact series, whether a rim-width range is stated, the tire’s weight, and any load specification that is included. Choosing the right option is really about matching the correct 19-inch fitment to the car’s use and the owner’s priorities.
Restoration & Appearance
Does correct tire fitment matter for a 2018 Tesla Model S restoration?
Yes, correct tire fitment still matters on a 2018 Tesla Model S, especially if the goal is to return the car to its proper visual stance and intended wheel setup. A standard 19-inch car and a Sport Package 21-inch car present very differently, and the 21-inch arrangement also depends on keeping separate front and rear sizes.
Appearance on a modern collector vehicle is shaped as much by wheel-and-tire proportion as by tread details. Anyone trying to bring the car back to a more original-looking configuration should verify whether it belongs on 245/45R19 or on the staggered 245/35R21 and 265/35R21 combination before choosing replacement tires.
How does tire construction affect the appearance of a restored 2018 Tesla Model S?
On the 2018 Tesla Model S, tire construction is straightforward because the primary fitments are radial across all listed sizes. That means the appearance difference is driven less by bias-ply versus radial choices and more by wheel diameter, profile, and whether the car uses the standard 19-inch setup or the lower-profile 21-inch Sport Package tires.
For a restoration-oriented owner, the visual question is really about preserving the correct proportion for the car’s intended configuration. A 245/45R19 presents differently than 245/35R21 and 265/35R21, so confirming the proper wheel package matters more here than searching for an alternate construction style.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 Tesla Model S?
Yes, modifications can affect tire fitment on a 2018 Tesla Model S. Wheel changes, suspension height changes, spacer use, or any move away from the original 19-inch or staggered 21-inch setup can alter clearance, tire position, and which size actually belongs on the car.
A quick visual check is not enough when the car has been changed from stock. Confirm the wheel diameter first, then verify front and rear sizes, especially on Sport Package applications. Looking at steering clearance, inner clearance, and fender clearance can help catch problems before a replacement tire is mounted and driven.
What should I inspect before driving a 2018 Tesla Model S on new tires?
Before driving a 2018 Tesla Model S on new tires, inspect the wheel size, tire size, and front-versus-rear placement to make sure the car is set up correctly. It is also wise to check inflation pressure, look for any visible mounting damage, and confirm that there is no rubbing at full steering lock or under suspension movement.
A few simple checks after installation can prevent avoidable problems. Recheck pressure after the first drives, pay attention to vibration or pull, and make sure the car’s staggered setup has not been mixed front to rear. On a low-use car, regular inspection remains important even when the tread still looks fresh.
How should tires on a collector 2018 Tesla Model S be maintained?
Tires on a collector 2018 Tesla Model S should be maintained with regular pressure checks, visual inspections, and attention to age-related condition as well as tread wear. Even a lightly used car can develop sidewall cracking, flat spotting from long storage, or gradual air loss that is easy to miss between drives.
Storage conditions matter on a low-mileage vehicle. Keeping the car away from prolonged sunlight, heat, and ozone sources can help preserve tire condition, while occasional movement helps reduce sitting stress. Before any longer drive, inspect the tires for cuts, bulges, or unusual wear and confirm that the wheel package still matches the tire sizes installed.
