The 2020 Chevrolet Impala represents the final stretch of Chevrolet’s long-running full-size sedan line, blending modern road manners with the roomy, comfortable character that kept the Impala name relevant for decades. For buyers at this level, tire selection is less about vintage construction and more about matching the exact trim and wheel package. The 2020 Chevrolet Impala uses radial tire fitments in three sizes: 235/50R18, 245/45R19, and 245/40R20. Available choices include Blackwall, Redline, and raised white letter sidewall treatments across several performance-oriented series. The key is confirming whether the car is an LT or Premier, then matching the tire to the actual wheel diameter and the look you want.
Which Tire Size Is Right for The 2020 Chevrolet Impala
Three tire sizes apply to the 2020 Chevrolet Impala, and the right one depends on the exact sub-model and wheel diameter. The LT uses 235/50R18, while the Premier uses either 245/45R19 or 245/40R20, all in radial construction. Before comparing brands or sidewall styles, confirm whether the car is an LT or Premier and verify whether it has 18-inch, 19-inch, or 20-inch wheels.
A 235/50R18 tire uses a 235-millimeter section width, a 50-series aspect ratio, radial construction, and an 18-inch rim diameter. On the 2020 Chevrolet Impala, this is the LT fitment and keeps the decision centered on choosing the right radial tire within that size. Available options include BFGoodrich, Nitto, and Pro-Trac, with Blackwall, Redline, and raised white letter sidewall treatments depending on the product line. This size is the right place to start if the car is an LT or if the wheel measures 18 inches across the bead seat.
A 245/40R20 tire is a metric radial with a 245-millimeter section width, a 40-series profile, and a 20-inch rim diameter. This size applies to certain 2020 Chevrolet Impala Premier configurations and reflects a lower-profile fitment than the 18-inch LT tire. Product choices include BFGoodrich, Nitto, and Pro-Trac, with Blackwall, Redline, and raised white letter presentations available depending on the series. This size should be evaluated when the car is a Premier and the wheel itself confirms a 20-inch setup rather than a 19-inch alternative.
A 245/45R19 tire combines a 245-millimeter section width with a 45-series profile in radial construction for a 19-inch wheel. On the 2020 Chevrolet Impala, this size is also used on certain Premier models, so trim alone is not enough without checking the wheel diameter. Available products in this size center on BFGoodrich and Nitto, with Blackwall sidewalls across several g-Force and NT555 G2 series choices. This fitment matters when the car is a Premier equipped with 19-inch wheels and the goal is to stay with the proper size before comparing tire character.
Sub-model fitment matters on the 2020 Chevrolet Impala because the LT and Premier do not share the same tire setup. Identifying the exact trim and confirming wheel diameter comes first, especially since the Premier can use either 19-inch or 20-inch tires.

2020 Chevrolet Impala LT
The 2020 Chevrolet Impala LT uses one radial tire size, which makes fitment relatively straightforward once the 18-inch wheel is confirmed. Tire selection then comes down to comparing available series, sidewall appearance, and rim-width compatibility within that size.
The 2020 Chevrolet Impala Premier uses two possible radial tire sizes, so wheel confirmation is essential before choosing a replacement. Once the car’s actual 19-inch or 20-inch wheel setup is verified, the next step is comparing the available product lines and sidewall treatments in the correct size.
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 2020 Chevrolet Impala tire questions usually come down to trim-specific sizing, wheel diameter, radial tire selection, sidewall appearance, and what to inspect before putting the car back into regular road use.
Tire Size & Fitment
What tire size fits a 2020 Chevrolet Impala?
The 2020 Chevrolet Impala uses three possible radial tire sizes: 235/50R18, 245/45R19, and 245/40R20. The LT uses 235/50R18, while the Premier uses either 245/45R19 or 245/40R20 depending on the wheel package on the car.
That means the first step is not choosing a brand but confirming the trim and the actual wheel diameter. A Premier owner especially needs to verify whether the car carries 19-inch or 20-inch wheels before selecting tires, because both sizes belong to that sub-model and are not interchangeable simply by trim name alone.
What size rim does a 2020 Chevrolet Impala use?
A 2020 Chevrolet Impala can use 18-inch, 19-inch, or 20-inch rims depending on the exact trim and wheel setup. The LT is tied to an 18-inch tire fitment, while the Premier uses either a 19-inch or 20-inch tire size.
Rim diameter should be verified directly at the wheel before replacing tires, especially on a used car that may have had wheel changes. Matching the tire’s final diameter number to the wheel is essential, and wheel width should also be checked against the tire’s approved range when comparing specific products.
Why does the 2020 Chevrolet Impala have more than one tire size?
More than one tire size appears on the 2020 Chevrolet Impala because fitment varies by sub-model and wheel package. The LT uses 235/50R18, while the Premier can use either 245/45R19 or 245/40R20, all in radial construction.
This is a normal trim-level difference rather than a sign that any of the three sizes can be used on any Impala. The practical takeaway is to identify the sub-model first, then confirm the actual wheel diameter on the car before comparing tread style, sidewall treatment, or brand options in the correct fitment.
Choosing the Right Tire
What should I consider when choosing a 2020 Chevrolet Impala tire?
Start with the correct size for the car: 235/50R18 for the LT, or 245/45R19 or 245/40R20 for the Premier. After that, compare the tire’s construction, rim-width compatibility, load figures where stated, and whether the tire’s overall character suits everyday driving or a more performance-oriented feel.
Appearance can matter too, especially since some Impala sizes offer more than one sidewall style. Once the correct size and wheel diameter are confirmed, it becomes easier to narrow the choice by brand, tire series, and whether a Blackwall, Redline, or raised white letter presentation better matches the way the car is used and maintained.
What sidewall styles are available for 2020 Chevrolet Impala tires?
Sidewall choice varies by size, but the 2020 Chevrolet Impala can be fitted with Blackwall, Redline, and RWL tires in certain fitments. Blackwall is the most common presentation across the available BFGoodrich and Nitto products, while Pro-Trac adds Redline and raised white letter options in selected sizes.
That gives the buyer a visual choice as well as a fitment decision. The best approach is to confirm the Impala’s exact size first, then check which sidewall treatments exist within that size, since not every style appears in every wheel diameter and appearance preference should never override correct fitment.
What brands offer tires for the 2020 Chevrolet Impala?
Tires for the 2020 Chevrolet Impala are available from BFGoodrich, Nitto, and Pro-Trac across the covered fitments. Depending on the size, the available series include g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, Nitto NT555 G2, and Pro-Trac Street Pro III.
Brand choice should be weighed alongside the exact size, wheel diameter, and sidewall treatment rather than by name alone. Some lines are offered only as Blackwalls, while others bring Redline or raised white letter styling, so the better comparison is how each product fits the car’s setup and the owner’s desired look.
Restoration & Appearance
Which tire should I choose for a period-style 2020 Chevrolet Impala?
A period-style approach on a 2020 Chevrolet Impala usually starts with keeping the exact trim-specific size and wheel diameter intact, then choosing a tire that gives the car the visual tone you want. In the covered fitments, that can mean staying with a Blackwall look or considering Pro-Trac Redline or raised white letter options where available.
Because this is a modern Impala, the appearance decision is more about style than restoration authenticity. The safest path is to preserve the proper size first, then use sidewall treatment and tire series to shape the presentation without drifting away from the wheel dimensions and fitment the car actually uses.
How does tire construction affect the appearance of a restored 2020 Chevrolet Impala?
On a 2020 Chevrolet Impala, construction does not create a bias-ply-versus-radial appearance decision because the primary fitments are radial. Visual differences come more from sidewall treatment and tire series than from changing to an older construction style.
That keeps the appearance choice focused on details such as Blackwall, Redline, or raised white letter styling in the correct size. For an owner aiming at a clean, original-looking presentation, matching the proper wheel diameter and then selecting the most suitable sidewall design will shape the car’s look more than anything else.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 Chevrolet Impala?
Yes, modifications can affect tire fitment on a 2020 Chevrolet Impala even when the tire size itself is one of the correct factory-style fitments. Aftermarket wheels, changes in wheel width, altered offset, suspension lowering, or body modifications can all change clearance at the fender, strut, or steering components.
A car that has been changed from stock should be checked as an actual wheel-and-tire package, not just by year and model. Measuring the wheel diameter and width, then inspecting turning clearance and full-compression space, helps prevent rubbing problems that would not show up on an unmodified LT or Premier setup.
What should I inspect before driving a 2020 Chevrolet Impala on new tires?
Before driving a 2020 Chevrolet Impala on new tires, inspect wheel condition, valve stems, lug hardware, and inflation pressure, then confirm that all four tires match the intended size for the car’s trim and wheel diameter. It also helps to look for uneven wear patterns that could point to alignment or suspension issues.
A short visual check after installation is worthwhile as well. Make sure there is no contact at full steering lock, verify that the tires seat properly on the wheels, and monitor pressure after the first several drives so any slow leak, mounting issue, or clearance concern is caught early.
How often should tires on a 2020 Chevrolet Impala be inspected?
Tires on a 2020 Chevrolet Impala should be inspected regularly, not just when tread appears low. A monthly pressure and condition check is a sensible routine, with closer attention before longer trips or after any curb impact, pothole strike, or noticeable change in ride quality.
Routine inspection should include tread wear, cuts, bulges, cracking, and any sign of irregular shoulder wear that may point to alignment or inflation issues. Even on a car that is not driven often, tires can age in place, so low annual mileage does not eliminate the need to keep an eye on condition.
