The 2021 Tesla Trucks Model Y brought all-electric crossover performance into a segment where wheel and tire choice has a clear effect on stance, response, and day-to-day use. Its low center of gravity and modern chassis tuning make tire fitment more than a cosmetic detail, especially across the different wheel packages offered for this model year. The 2021 Tesla Trucks Model Y uses radial tires in four primary sizes: 255/45R19, 255/40R20, 255/35R21, and 275/35R21. That means the first step is confirming the exact sub-model and wheel setup, then comparing the available tire choice within the proper size for appearance, road use, and overall fitment.
Which Tire Size Is Right for The 2021 Tesla Trucks Model Y
The 2021 Tesla Trucks Model Y uses four primary tire sizes, and they do not all apply to the same configuration. Fitment changes by sub-model and wheel diameter, so the first step is identifying whether the vehicle is a Long Range or a Performance model and then confirming the actual wheel setup on the car. Once that is settled, the decision becomes choosing the right tire within the correct radial size.
A 255/40R20 tire uses a 255-millimeter section width, a 40-series aspect ratio, radial construction, and a 20-inch rim diameter. On the 2021 Tesla Trucks Model Y, this is one of the primary Long Range fitments and keeps the sizing in a modern radial format familiar to late-model buyers. Available product choice in this size includes BFGoodrich in the g-Force Phenom T/A series with a Blackwall sidewall treatment. This size is the right one to evaluate when the vehicle is equipped with 20-inch wheels and the goal is to stay with the proper Long Range fitment family.
A 255/45R19 tire carries the same 255-millimeter nominal width but pairs it with a taller 45-series profile on a 19-inch rim. On the 2021 Tesla Trucks Model Y, this size belongs to the Long Range configuration and should be considered only when the vehicle is actually running the 19-inch wheel setup. The modern metric radial format makes the size easy to interpret, but wheel diameter still matters first because a 19-inch tire cannot be used on a 20-inch or 21-inch rim. This size is the one to focus on when maintaining the correct Long Range wheel-and-tire combination.
A 255/35R21 tire uses a 255-millimeter width, a lower 35-series profile, radial construction, and a 21-inch rim diameter. On the 2021 Tesla Trucks Model Y, this size is used at the front of the Performance configuration, so it should not be treated as a universal fitment across the full model range. Its role is tied to the staggered 21-inch Performance setup rather than the Long Range wheel packages. This is the front size to verify when the vehicle has 21-inch Performance wheels and the tire choice needs to match that specific position.
A 275/35R21 tire combines a wider 275-millimeter section width with a 35-series profile on a 21-inch rim. On the 2021 Tesla Trucks Model Y, this is the rear tire size for the Performance configuration, making it part of a staggered front-to-rear arrangement rather than a same-size setup at all four corners. The added width compared with the 255 front size is an important clue that wheel position matters as much as rim diameter here. This size should be checked against the rear wheel specifically before comparing replacement options.
Tire fitment on the 2021 Tesla Trucks Model Y depends on the exact sub-model and wheel package. Long Range models use either 19-inch or 20-inch sizing, while Performance models use a staggered 21-inch setup with different front and rear tire sizes.

2021 Tesla Trucks Model Y Long Range
The 2021 Tesla Trucks Model Y Long Range uses either 255/45R19 or 255/40R20, both in radial construction. That makes wheel diameter the key detail to confirm before choosing a tire, since the correct replacement depends on whether the vehicle has the 19-inch or 20-inch setup.
The 2021 Tesla Trucks Model Y Performance Front uses 255/35R21 radial tires. Tire selection here should stay focused on the front position of the staggered 21-inch Performance setup so the sizing remains consistent with the vehicle's wheel arrangement.
The 2021 Tesla Trucks Model Y Performance Rear uses 275/35R21 radial tires. That wider rear fitment means replacement choices should be made with the rear wheel position in mind rather than assuming the same tire size is used at all four corners.
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 2021 Tesla Trucks Model Y?
The 2021 Tesla Trucks Model Y uses four primary tire sizes: 255/45R19, 255/40R20, 255/35R21, and 275/35R21. The Long Range model uses either 255/45R19 or 255/40R20, while the Performance model uses a staggered 21-inch setup with 255/35R21 in front and 275/35R21 in the rear.
That means the correct size depends on the exact version of the vehicle and the wheels currently installed. Checking the sub-model alone is not always enough, because the Long Range can use two different rim diameters, and the Performance fitment depends on front-versus-rear wheel position.
What size rim does a 2021 Tesla Trucks Model Y use?
The 2021 Tesla Trucks Model Y uses 19-inch, 20-inch, and 21-inch rim diameters depending on configuration. The 255/45R19 tire fits a 19-inch rim, the 255/40R20 fits a 20-inch rim, and the 255/35R21 and 275/35R21 fit 21-inch rims on the Performance setup.
Rim diameter is the first thing to verify before comparing tires, because the tire size must match the wheel exactly. A quick wheel check can prevent choosing the right width and profile in the wrong diameter, which is especially important on a Model Y with multiple factory-style wheel configurations.
Why does the 2021 Tesla Trucks Model Y have more than one tire size?
More than one tire size applies because the 2021 Tesla Trucks Model Y was offered in different configurations. Long Range models use either a 19-inch or 20-inch setup, while Performance models use a staggered 21-inch arrangement with one size for the front and a wider size for the rear.
That variety means tire replacement is tied to how the individual vehicle is equipped, not just the model name on the liftgate. Looking at the current wheel diameter and confirming whether the vehicle is Long Range or Performance will narrow the choice to the correct size much faster.
Choosing the Right Tire
What should I consider when choosing a 255/40R20 tire for a 2021 Tesla Trucks Model Y?
A 255/40R20 tire for the 2021 Tesla Trucks Model Y should first match the vehicle's actual 20-inch Long Range wheel setup. After size is confirmed, useful comparison points include radial construction, sidewall style, rim-width compatibility, max load capacity, tire weight, and the character of the tire series being considered.
The available 255/40R20 product choice includes a BFGoodrich g-Force Phenom T/A Blackwall radial with an 8.5- to 10-inch rim-width range. That makes it important to confirm the wheel width on the vehicle so the tire's specifications align with the wheel as well as the intended road use.
What sidewall styles are available for 2021 Tesla Trucks Model Y tires?
Current product choice for the 2021 Tesla Trucks Model Y includes a Blackwall sidewall style in 255/40R20. On a modern electric crossover like the Model Y, Blackwall is a straightforward visual match that keeps the tire presentation clean and contemporary without introducing a vintage-style sidewall treatment.
Sidewall choice affects appearance more than fitment, so it should be considered after the correct size and wheel diameter are confirmed. Buyers comparing tires for a Long Range model with 20-inch wheels can use sidewall style as part of the final selection process once the basic dimensional and wheel-compatibility questions are settled.
What brands offer tires for the 2021 Tesla Trucks Model Y?
BFGoodrich is currently represented for the 2021 Tesla Trucks Model Y in the available product selection, specifically in 255/40R20. The tire series offered in that size is the g-Force Phenom T/A, giving buyers a clearly defined option within the 20-inch Long Range fitment.
Brand matters most after the correct size, wheel diameter, and vehicle configuration are confirmed. A buyer with 20-inch Long Range wheels can then compare the BFGoodrich option against priorities such as sidewall appearance, rim-width compatibility, load specification, and how the tire's overall character fits the way the Model Y is used.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2021 Tesla Trucks Model Y?
Yes, modifications can affect tire fitment on a 2021 Tesla Trucks Model Y even when the tire size itself looks correct. Aftermarket wheels, changes in wheel width, offset differences, suspension lowering, and alignment changes can all alter how a 255/45R19, 255/40R20, 255/35R21, or 275/35R21 tire sits in the wheel opening.
Clearance should be checked at full steering lock and through normal suspension movement, especially on the staggered 21-inch Performance setup. A vehicle that has been changed from its original wheel package should be measured as it sits, rather than relying only on the tire size associated with the original configuration.
What should I inspect before driving a 2021 Tesla Trucks Model Y on new tires?
Before driving a 2021 Tesla Trucks Model Y on new tires, inspect wheel condition, valve stems, inflation pressure, tread and sidewall condition, and the basic wheel-to-tire match. On a Performance model, verify that the front and rear tires are in their proper positions because the 21-inch setup uses different sizes at each end.
It also helps to confirm that there is no rubbing at the fender, suspension, or steering components once the tires are mounted. A short initial road check, followed by a second look at pressure and visible clearance, can catch setup issues early before regular driving begins.
What should I check before a longer drive in a 2021 Tesla Trucks Model Y?
A longer drive in a 2021 Tesla Trucks Model Y starts with confirming that the tires match the vehicle's actual wheel package and are inflated properly for use. It is also wise to inspect for cuts, bulges, irregular wear, embedded debris, or slow air loss, particularly if the vehicle has been sitting or has recently had tire service.
Wheel torque, visible clearance, and overall tire condition deserve a final check before heading out. On a Model Y with staggered 21-inch Performance tires, double-check that the 255/35R21 front and 275/35R21 rear positions have not been mixed, since size placement is part of the fitment itself.
