The 2021 Tesla Model 3 sits at an important point in the modern EV market, blending compact-sedan packaging with the instant response and low center of gravity that drew many buyers to Tesla in the first place. Tire choice matters on this car because wheel and trim combinations change the fitment story: 235/45R18 and 235/40R19 serve Long Range and Standard Plus models, while Performance models use 235/35R20. All three are radial metric fitments, with a clear emphasis on matching the correct rim diameter first. From there, the real decision is selecting the right series and construction details for your driving use, wheel setup, and overall presentation.
Which Tire Size Is Right for The 2021 Tesla Model 3
The 2021 Tesla Model 3 uses three primary tire sizes, and the right one depends on the exact sub-model and wheel diameter. Long Range and Standard Plus models use either 235/45R18 or 235/40R19, while the Performance model uses 235/35R20, so confirming the car's trim and actual wheel size comes before comparing tire options.
In 235/40R19, the 235 identifies the nominal section width in millimeters, 40 is the aspect ratio, R denotes radial construction, and 19 is the wheel diameter in inches. This is a modern radial fitment for certain 2021 Tesla Model 3 Long Range and Standard Plus configurations, so it should be matched to a 19-inch wheel. Available choices in this size include BFGoodrich with a Blackwall sidewall and the g-Force Phenom T/A series. It is the right size to evaluate when the car already has the corresponding 19-inch wheel package and you want to stay within that fitment.
The size 235/45R18 uses the same 235-millimeter nominal width, but the 45 aspect ratio pairs with an 18-inch wheel for a different overall package than the 19-inch and 20-inch options. This radial size applies to certain 2021 Tesla Model 3 Long Range and Standard Plus configurations and should be chosen only when the car is running 18-inch wheels. Product choices here are broader, including BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A, all in Blackwall form. It is the size to compare when you want the 18-inch fitment and need to sort through series differences within that setup.
With 235/35R20, the tire keeps the same nominal 235-millimeter width but uses a lower 35-series profile on a 20-inch wheel. This is the radial fitment tied to the 2021 Tesla Model 3 Performance, making wheel diameter confirmation especially important before selection. Available products include Blackwall options from Nitto and BFGoodrich, with series choices such as the NT555 G2 and g-Force Phenom T/A. It is the size to focus on when the car has the 20-inch Performance-style wheel setup and you want to compare product character within that exact fitment.
Sub-model fitment matters on the 2021 Tesla Model 3 because tire size changes with trim and wheel package. Long Range and Standard Plus share the same primary size choices, while Performance models move to a distinct 20-inch fitment.

2021 Tesla Model 3 Long Range
The 2021 Tesla Model 3 Long Range uses radial tire fitments in 235/45R18 or 235/40R19, depending on the wheel package on the car. Tire selection starts with confirming whether the vehicle is on 18-inch or 19-inch wheels, then comparing the available series within that exact size.
The 2021 Tesla Model 3 Performance uses a 235/35R20 radial tire, setting it apart from the other covered trims. That makes 20-inch wheel confirmation the key first step, followed by choosing between the available Blackwall performance-oriented tire options in that size.
The 2021 Tesla Model 3 Standard Plus uses the same radial size choices as the Long Range model: 235/45R18 or 235/40R19. The main task is verifying the actual wheel diameter on the car, then selecting the tire series that best suits the intended driving use and setup.
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.

Common 2021 Tesla Model 3 tire questions usually come down to identifying the correct size by sub-model and wheel diameter, then comparing radial product choices, rim fitment, and road-use considerations before installation.
Tire Size & Fitment
What tire size fits a 2021 Tesla Model 3?
The 2021 Tesla Model 3 uses three primary tire sizes: 235/45R18, 235/40R19, and 235/35R20. Long Range and Standard Plus models use either 235/45R18 or 235/40R19, while the Performance model uses 235/35R20.
The correct choice depends on both the sub-model and the wheel diameter currently on the car. A Model 3 that has had wheels changed since new should be measured and verified before ordering tires, because the right tire for an 18-inch wheel is not the right tire for a 19-inch or 20-inch setup.
What size rim does a 2021 Tesla Model 3 use?
A 2021 Tesla Model 3 uses 18-inch, 19-inch, or 20-inch rims depending on the specific trim and wheel package. The 235/45R18 size fits an 18-inch rim, 235/40R19 fits a 19-inch rim, and 235/35R20 fits a 20-inch rim.
Rim diameter is the first fitment point to confirm because the tire must match the wheel exactly. It also helps to verify wheel width before comparing products, especially if the car has aftermarket wheels, since some tire options in these sizes carry specific rim-width ranges that should align with the wheel already on the vehicle.
Do all 2021 Tesla Model 3 sub-models use the same tire size?
No. The 2021 Tesla Model 3 Long Range and Standard Plus share 235/45R18 and 235/40R19 fitments, while the 2021 Tesla Model 3 Performance uses 235/35R20. That means tire size is not uniform across the full Model 3 lineup for this year.
This matters because selecting by year and model alone is not enough when the trim changes the wheel and tire package. Checking the badge, wheel diameter, and the size stamped on the current tire is the safest way to narrow the correct fitment before comparing brands, series, sidewall style, and other product details.
Choosing the Right Tire
What should I consider when choosing a 2021 Tesla Model 3 tire?
Start with the exact tire size that matches the car's sub-model and wheel diameter: 235/45R18, 235/40R19, or 235/35R20. From there, compare the tire series, radial construction details, and any product specifications that matter for your intended use, such as rim-width compatibility, weight, or load figures where stated.
A daily-driven Model 3 and a car used more aggressively may lead you toward different product characteristics even within the same size. It also makes sense to confirm the wheel setup on the car today, since a previous owner may have changed wheels, and that can matter more than the trim name alone when choosing the right tire.
What sidewall styles are available for 2021 Tesla Model 3 tires?
The available 2021 Tesla Model 3 tire options here use a Blackwall sidewall style across all three primary sizes. That includes the 18-inch, 19-inch, and 20-inch fitments offered for Long Range, Standard Plus, and Performance configurations.
Because the sidewall presentation is consistent, the main visual and functional differences come from tire series and brand rather than stripe or letter treatments. Buyers who want a clean modern look can focus more closely on size, wheel compatibility, and series selection without needing to sort through multiple sidewall styles for this vehicle fitment.
What brands offer tires for the 2021 Tesla Model 3?
BFGoodrich and Nitto are available within the 2021 Tesla Model 3 fitments covered here. BFGoodrich appears in all three primary sizes, while Nitto appears in the 235/35R20 fitment used on the Performance model.
Brand is only one part of the decision, since the available tire series differ by size and trim. It helps to compare the actual size you need first, then look at the series offered in that fitment, along with rim-width guidance and any stated load or weight details that may matter for your wheel setup and use.
Restoration & Appearance
Does correct tire fitment matter for a 2021 Tesla Model 3 restoration or refurbishment?
Yes. Even on a modern vehicle like the 2021 Tesla Model 3, correct tire size still shapes stance, wheel relationship, and overall presentation. Using 235/45R18, 235/40R19, or 235/35R20 as appropriate to the car's actual wheel setup keeps the appearance aligned with the intended trim and wheel package.
A refurbishment-minded owner should confirm whether the car still has its original wheel diameter before choosing tires on appearance alone. The wrong rim-size pairing can disrupt both looks and fitment, so matching the tire to the actual 18-, 19-, or 20-inch wheel is the best starting point before comparing tire series.
How does tire construction affect the appearance of a 2021 Tesla Model 3?
For the 2021 Tesla Model 3, the primary fitments are all radial metric sizes, so the appearance differences come more from profile and wheel diameter than from switching between bias-ply and radial construction. An 18-inch, 19-inch, or 20-inch setup changes the visual character of the car even though each size remains within a similar overall diameter range.
That means a buyer focused on presentation should think first about the actual wheel package on the car and the tire's series within that size. Since the available products here are Blackwall radials, the visual choice is more about preserving the intended wheel-and-tire proportion than selecting a dramatically different sidewall style.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2021 Tesla Model 3?
Yes. A 2021 Tesla Model 3 with aftermarket wheels, changed offsets, suspension lowering, or other wheel-and-tire modifications may need different fitment checks than a stock car. Even when the tire size matches one of the primary Model 3 sizes, the full wheel and clearance package can still change the result.
That is why it helps to verify actual wheel diameter, wheel width, and clearance at the fender and suspension before replacing tires on a modified car. Steering clearance and load suitability also deserve attention, especially when moving between wheel packages that did not originally belong to the trim currently being serviced.
What should I inspect before driving a 2021 Tesla Model 3 on new tires?
Before driving, inspect that the new tires match the correct 18-inch, 19-inch, or 20-inch wheel diameter and are seated properly on the wheels. It also makes sense to check inflation pressure, look over the sidewalls for shipping damage, and confirm there is no interference at the suspension or body once the car is back on the ground.
A short, careful road test is useful for catching vibration, rubbing, or handling changes early. Rechecking pressure after installation and watching for any sign of air loss can prevent problems from being missed, particularly if the Model 3 has wheel changes or has been sitting long enough for tire and valve condition to deserve extra attention.
How often should tires on a 2021 Tesla Model 3 be inspected?
Tires on a 2021 Tesla Model 3 should be inspected regularly rather than waiting for an obvious problem. Checking tread wear, cuts, cracking, bulges, and inflation pressure on a routine schedule helps catch issues before they affect ride quality, range, or general road manners.
A closer inspection is especially worthwhile before longer trips or after striking potholes and road debris. Owners should also pay attention to uneven wear patterns, since they can point to alignment, wheel, or suspension issues that matter just as much as the tire itself when maintaining the correct fitment and safe road use.
