The 2018 Tesla Model 3 arrived as Tesla’s first true high-volume sport sedan, blending sharp acceleration, minimalist design, and everyday usability in a package that quickly became a reference point for modern EV ownership. Tire choice matters more than it might on an older luxury sedan because the Model 3’s wheel and tire setup plays directly into ride quality, handling response, and overall presentation. This year uses radial fitments in 235/45R18, 235/40R19, and 235/35R20 depending on configuration. Available choices center on blackwall performance-oriented tires from BFGoodrich and Nitto across several series. The key is matching the exact sub-model and wheel diameter before comparing tire character, load capability, and intended road use.
Which Tire Size Is Right for The 2018 Tesla Model 3
The 2018 Tesla Model 3 uses three primary tire sizes, and the right one depends first on the exact sub-model and wheel diameter. All three are radial metric sizes, but they are tied to different 18-inch, 19-inch, and 20-inch wheel setups. Before choosing a tire, confirm whether the car is running its original wheel package or a later wheel change, since that determines which size belongs on the car.
A 235/40R19 tire uses a 235-millimeter nominal section width, a 40-series aspect ratio, radial construction, and a 19-inch rim. On the 2018 Tesla Model 3, this size is part of the primary radial fitment and suits cars equipped with the 19-inch wheel package. Available choices include blackwall BFGoodrich options such as the g-Force Phenom T/A, giving the size a distinctly modern performance-tire character. This is the size to evaluate when the car has 19-inch wheels and the goal is to preserve the intended balance of response, stance, and wheel-to-tire proportion.
A 235/45R18 tire keeps the same 235-millimeter nominal width but uses a taller 45-series profile on an 18-inch rim. This radial size appears across multiple 2018 Tesla Model 3 sub-models, making it a central fitment for owners running the 18-inch wheel setup. Product choices include several BFGoodrich g-Force series in blackwall form, so selection can focus on series characteristics, rim-width compatibility, and other product details rather than sidewall styling. It is the right size to review when the car wears 18-inch wheels and the buyer wants the proper primary fitment for that wheel diameter.
A 235/35R20 tire pairs a 235-millimeter nominal width with a lower 35-series profile and a 20-inch rim. For the 2018 Tesla Model 3, this size is associated with the 20-inch radial fitment and carries a more aggressive wheel-and-tire presentation than the 18-inch or 19-inch alternatives. Available blackwall options include Nitto NT555 G2 and BFGoodrich g-Force Phenom T/A, which gives owners a choice between two established performance-oriented series. This size deserves close attention when confirming a Performance-model wheel package or checking a car that may have been upgraded from another wheel diameter.
Sub-model fitment matters on the 2018 Tesla Model 3 because tire size is not identical across every version. Some configurations share the 18-inch setup, while others add 19-inch or 20-inch wheel packages, so identifying the exact sub-model and actual wheel diameter is the first step before comparing tires.

2018 Tesla Model 3 Base
The 2018 Tesla Model 3 Base uses radial fitments tied to either the 18-inch or 19-inch wheel setup. Tire selection starts with confirming which wheel package is on the car, then comparing blackwall performance-tire choices within that exact size.
The 2018 Tesla Model 3 Long Range also uses radial tires in either the 18-inch or 19-inch fitment range. That makes wheel confirmation especially important, since the decision is less about construction and more about matching the correct size to the actual wheels on the car.
The 2018 Tesla Model 3 Performance can use the 18-inch radial size or the lower-profile 20-inch radial setup. Buyers should verify whether the car still has its intended wheel package, because tire selection changes significantly once the rim diameter moves from 18 to 20 inches.
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 2018 Tesla Model 3?
The 2018 Tesla Model 3 uses three primary tire sizes: 235/45R18, 235/40R19, and 235/35R20. All of them are radial metric sizes, but they do not apply universally across every car because wheel package and sub-model determine which one belongs on the vehicle.
The most important check is the actual wheel diameter on the car today. A Base or Long Range car may use 18-inch or 19-inch wheels, while a Performance model may use 18-inch or 20-inch fitment, so the correct tire starts with matching the wheel rather than choosing by appearance alone.
What size rim does a 2018 Tesla Model 3 use?
A 2018 Tesla Model 3 can use 18-inch, 19-inch, or 20-inch rims depending on the sub-model and wheel setup. Those rim diameters correspond to the primary tire sizes 235/45R18, 235/40R19, and 235/35R20.
Rim diameter needs to be confirmed before anything else because a 19-inch tire cannot be mounted on an 18-inch or 20-inch wheel. If the car has changed hands or has aftermarket wheels, checking the wheel markings and measuring the current setup helps avoid ordering the right tire size for the wrong rim.
Why does the 2018 Tesla Model 3 have more than one tire size?
The 2018 Tesla Model 3 has more than one tire size because different sub-models and wheel packages use different rim diameters. The Base and Long Range models can use 235/45R18 or 235/40R19, while the Performance model can use 235/45R18 or 235/35R20.
That means the right size is tied to the exact configuration and the wheels currently on the car. Two Model 3s from the same year may need different tires even though both are correct within their own setup, so the best approach is to verify sub-model, wheel diameter, and any later wheel changes together.
Choosing the Right Tire
What should I consider when choosing a 2018 Tesla Model 3 tire?
Start with the correct primary size for the car: 235/45R18, 235/40R19, or 235/35R20. From there, compare radial construction details such as rim-width compatibility, load capacity where stated, tire weight, and the specific tire series available in that size.
The available Model 3 choices are all blackwall performance-oriented radials, so the decision usually comes down to matching the wheel package and selecting the tire character that suits daily driving, sharper response, or a lower-profile look. A car with changed wheels should always be checked carefully before narrowing the choice.
What brands offer tires for the 2018 Tesla Model 3?
Tires for the 2018 Tesla Model 3 are available here from BFGoodrich and Nitto, depending on the size. BFGoodrich covers all three primary sizes, while Nitto appears in the 235/35R20 fitment used with the 20-inch setup.
Brand comparison only matters after the correct size is confirmed. Once that is settled, the real differences are found in the tire series, rim-width specification where published, and load or weight details, rather than assuming one brand applies across every Model 3 wheel package.
What tire series are available for the 2018 Tesla Model 3?
Available tire series for the 2018 Tesla Model 3 include BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and Nitto NT555 G2. Not every series is offered in every size, so the exact wheel and tire size determine which series can be compared.
That makes size confirmation especially important before focusing on tread category or brand preference. An 18-inch Model 3 has the broadest series choice in this group, while the 19-inch and 20-inch sizes narrow the field, so the smartest comparison is always made within the correct size first.
Restoration & Appearance
Which tire should I choose for a period-style 2018 Tesla Model 3?
A period-style approach on a 2018 Tesla Model 3 usually means staying with the primary radial size that matches the car’s wheel package and preserving its clean, modern blackwall look. Since this is a contemporary EV rather than a vintage restoration vehicle, size accuracy and wheel fitment matter more than recreating a historic sidewall treatment.
The visual decision comes from the wheel diameter itself: 18-inch, 19-inch, or 20-inch. Keeping the car on the intended size range maintains the proportion Tesla owners typically expect, while switching wheel diameters can change the stance and presentation enough that the tire choice should be reviewed as part of the whole setup.
Does correct tire fitment matter for a 2018 Tesla Model 3 restoration or preservation-minded build?
Yes, correct tire fitment still matters on a 2018 Tesla Model 3 even though it falls outside the traditional collector-car era. Using the proper 235/45R18, 235/40R19, or 235/35R20 size for the wheel setup helps preserve the car’s intended visual balance and keeps the build closer to an authentic year-specific presentation.
A preservation-minded owner should confirm whether the car still carries its original-style wheel diameter before choosing among available tires. Even within modern blackwall radial options, the difference between 18-inch, 19-inch, and 20-inch fitment changes the overall look enough that the wrong size can make the car appear noticeably off.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 Tesla Model 3?
Yes, modifications can affect tire fitment on a 2018 Tesla Model 3. Wheel changes, altered offsets, suspension lowering, and body or fender modifications can all change how a 235/45R18, 235/40R19, or 235/35R20 tire sits and clears during turning and suspension movement.
A Model 3 with aftermarket wheels should be checked for actual rim diameter and width before selecting a tire from the original size range. Clearance at the fender, inner wheelhouse, and steering lock deserves attention as well, especially when moving to the lower-profile 20-inch setup or retaining a modified suspension height.
What should I inspect before driving a 2018 Tesla Model 3 on new tires?
Before driving a 2018 Tesla Model 3 on new tires, confirm that the tire size matches the wheel diameter and that the tires are mounted on suitable rims. It also helps to inspect for proper inflation, secure wheel hardware, and any signs that the tire is contacting suspension parts, liners, or fender edges.
A short initial road test can reveal vibration, rubbing, or steering behavior that needs attention before regular use. Rechecking pressure after the first drive and looking again for clearance issues is worthwhile, particularly on cars with 20-inch fitment or any wheel and suspension changes from the original setup.
How often should tires on a 2018 Tesla Model 3 be inspected?
Tires on a 2018 Tesla Model 3 should be inspected regularly, not just when tread appears worn. Frequent checks for uneven wear, cuts, bulges, cracking, and air loss are especially useful on a vehicle where wheel size and tire profile can vary significantly between 18-inch, 19-inch, and 20-inch setups.
A practical routine is to inspect the tires during pressure checks and before longer trips. Owners should also pay attention after pothole impacts, curb contact, or seasonal wheel changes, since a lower-profile size like 235/35R20 gives less visual sidewall cushion and makes close condition monitoring more important.
