The 2019 Chevrolet Impala represents the final stretch of Chevrolet’s full-size front-wheel-drive sedan, blending roomy comfort with a more modern, upscale look than many buyers expect from a traditional American four-door. Tire selection on this car is driven by trim level and wheel package, with radial fitments in 235/50R18, 245/45R19, and 245/40R20. That means the real choice is not vintage-style construction, but matching the correct size to the exact LS, LT, or Premier setup and then choosing among blackwall, redline, or raised white letter presentations where offered. Wheel diameter, intended appearance, and any changes from the original wheel package should be confirmed before replacing tires.
Which Tire Size Is Right for The 2019 Chevrolet Impala
The 2019 Chevrolet Impala uses three primary tire sizes, and the right one depends on the exact sub-model and wheel package. Fitment varies across 18-inch, 19-inch, and 20-inch rims, so the first step is confirming the car’s current wheel diameter before choosing a tire. Once that is settled, the next decision becomes tire series, brand, sidewall style, and whether the tire matches the car’s intended use and appearance.
235/50R18 is a metric radial size in which 235 identifies the nominal section width in millimeters, 50 is the aspect ratio, R marks radial construction, and 18 is the wheel diameter in inches. On the 2019 Chevrolet Impala, this size suits 18-inch applications and keeps the selection centered on modern radial performance rather than construction changes. Available choices include BFGoodrich, Nitto, and Pro-Trac options, with blackwall, redline, and raised white letter styling depending on the tire. This size is worth considering when the car retains its 18-inch wheel setup and the goal is to balance proper fitment with the preferred look and driving character.
245/45R19 is a metric radial size that uses a 245-millimeter nominal section width, a 45-series profile, and a 19-inch rim diameter. For the 2019 Chevrolet Impala, it serves specific 19-inch configurations, so it should be chosen only after the wheel size is confirmed. Product selection in this size includes BFGoodrich and Nitto blackwall radials across g-Force and NT555 G2 series. It is the right size to evaluate when the car is equipped with 19-inch wheels and the buyer wants to compare brand character, tread family, and rim-width compatibility within the correct fitment.
245/40R20 is a metric radial size with a 245-millimeter nominal section width, a lower 40-series profile, and a 20-inch wheel diameter. On the 2019 Chevrolet Impala, this size belongs to 20-inch applications and brings the most wheel-dependent fitment of the three primary sizes. Available products include BFGoodrich, Nitto, and Pro-Trac offerings, with blackwall, redline, and raised white letter sidewall treatments represented in the selection. This size deserves close attention when the car carries factory-style or aftermarket 20-inch wheels, since wheel width and overall clearance should be checked before settling on a replacement.
Sub-model fitment matters on the 2019 Chevrolet Impala because tire size changes with trim and wheel package. The LS stays straightforward, while LT and Premier configurations can overlap or move to larger rim diameters, making exact sub-model and wheel confirmation important before buying tires.

2019 Chevrolet Impala LS
The 2019 Chevrolet Impala LS uses a single radial tire size, which makes replacement more straightforward than on the other trims. Tire selection then comes down to staying with the proper 18-inch fitment and comparing the available brand, series, and sidewall-style choices in that size.
The 2019 Chevrolet Impala LT can use either an 18-inch or 19-inch radial tire size, so the wheel diameter on the car needs to be verified before anything else. Once that is confirmed, the decision shifts to choosing the tire series and overall presentation that best suits a daily-driven sedan or a more customized look.
The 2019 Chevrolet Impala Premier uses larger-wheel radial fitments, with 19-inch and 20-inch applications both appearing in this trim. That makes wheel confirmation especially important, and it also opens the door to comparing blackwall performance-style tires against redline or raised white letter options where available.
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.

Owners of a 2019 Chevrolet Impala usually need clarity on exact tire size by trim, wheel diameter, sidewall options, and how to compare the available radial tire lines. The questions below focus on fitment, product selection, appearance, and the checks worth making before the car goes back on the road.
Tire Size & Fitment
What tire size fits a 2019 Chevrolet Impala?
The 2019 Chevrolet Impala uses three primary radial tire sizes: 235/50R18, 245/45R19, and 245/40R20. The correct size depends on the exact trim and wheel package, with LS using 235/50R18, LT using either 235/50R18 or 245/45R19, and Premier using either 245/45R19 or 245/40R20.
That makes wheel verification the first step before replacing tires. The easiest way to avoid a mismatch is to confirm the current rim diameter on the car and then match the tire size to that setup, especially if the Impala has changed hands, had wheel upgrades, or no longer carries its original trim-level wheel package.
What size rim does a 2019 Chevrolet Impala use?
A 2019 Chevrolet Impala can use 18-inch, 19-inch, or 20-inch rims, depending on sub-model and wheel package. The 235/50R18 size uses an 18-inch rim, 245/45R19 uses a 19-inch rim, and 245/40R20 uses a 20-inch rim.
Rim diameter matters because tire sizes are not interchangeable across different wheel diameters. Even though the overall tire diameters stay fairly close, the tire still has to match the wheel exactly, so the buyer should confirm the car’s actual wheel setup before comparing brands, sidewall styles, or tire series.
Why does the 2019 Chevrolet Impala have more than one tire size?
The 2019 Chevrolet Impala has more than one tire size because fitment changes by trim and wheel package. LS uses one size, while LT and Premier can use larger wheel diameters that bring different tire dimensions and profiles into the equation.
That means the right replacement is tied to how the specific car is equipped, not just the model name on the trunk. Checking the trim helps, but confirming the wheel diameter on the vehicle is still the safer move, especially on used cars or any Impala that may have received different factory-style wheels or aftermarket replacements.
Choosing the Right Tire
What should I consider when choosing a 2019 Chevrolet Impala tire?
Start with the exact tire size that matches the car’s wheel diameter, then compare construction, tire series, sidewall treatment, and rim-width compatibility within that size. On a 2019 Chevrolet Impala, the choice is always among radial tires, but the available products vary in character and presentation.
A practical approach is to decide whether the car needs a straightforward blackwall replacement or something with more visual impact, such as redline or raised white letter styling where offered. It also helps to confirm the wheel width and review any load figures shown for the tire, particularly if the car carries larger wheels.
What sidewall styles are available for 2019 Chevrolet Impala tires?
Sidewall choices for the 2019 Chevrolet Impala include blackwall across all three primary sizes, with redline and raised white letter options appearing in selected 18-inch and 20-inch fitments. Those appearance choices show up most clearly in the Pro-Trac Street Pro III line.
The sidewall decision changes the car’s visual character more than its basic fitment. Blackwall keeps the look clean and modern, while redline and raised white letter add a more customized presentation, so the best choice depends on whether the Impala is being kept understated or given a sportier, more personalized stance.
What brands offer tires for the 2019 Chevrolet Impala?
Tires for the 2019 Chevrolet Impala are available from BFGoodrich, Nitto, and Pro-Trac across the covered sizes. Depending on the exact fitment, the selection includes g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, Nitto NT555 G2, and Pro-Trac Street Pro III options.
Choosing among them comes down to selecting the proper size first and then comparing the type of tire each brand offers in that fitment. Some options focus on blackwall modern radial presentation, while others add redline or raised white letter styling, so the right brand choice is often tied to the look and use of the car.
Restoration & Appearance
Which tire should I choose for a period-style 2019 Chevrolet Impala?
A period-style direction on a 2019 Chevrolet Impala is less about vintage construction and more about choosing the correct modern radial size with the right visual treatment. Blackwall keeps the look closest to a typical late-model full-size sedan presentation, while redline or raised white letter options add a more customized appearance.
The best starting point is the tire size that matches the car’s actual wheel diameter, then the sidewall can be chosen to suit the overall theme. Since this is a recent model, appearance preferences usually matter more than strict restoration concerns, but wheel-package accuracy still shapes how authentic the finished car looks.
How does tire construction affect the appearance of a restored 2019 Chevrolet Impala?
Tire construction does not create a bias-ply versus radial decision on the 2019 Chevrolet Impala, because the primary fitments are radial throughout. The appearance difference comes instead from profile, wheel diameter, and sidewall styling, especially when comparing 18-inch, 19-inch, and 20-inch setups.
That means a clean restoration-oriented result depends on keeping the tire size in step with the intended trim-level look and avoiding mismatched wheel-and-tire combinations. A blackwall radial tends to preserve a more stock-style presentation, while redline or raised white letter choices give the car a distinctly customized visual tone.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 Chevrolet Impala?
Yes, modifications can affect tire fitment on a 2019 Chevrolet Impala, especially when wheel diameter, wheel width, offset, or suspension height has been changed. The car may have originally used one of several sizes, so aftermarket parts can make the fitment question more complicated than trim level alone suggests.
A modified Impala should be checked for wheel clearance, steering clearance, and fender room before new tires are selected. It is also smart to confirm the exact wheel dimensions already on the car, since a tire that matches the original trim-level size may not be the right choice for a different wheel setup.
What should I inspect before driving a 2019 Chevrolet Impala on new tires?
Before driving a 2019 Chevrolet Impala on new tires, inspect the wheel size, tire pressure, lug torque, tread and sidewall condition, and overall clearance at full steering lock. It also helps to look over the suspension and alignment condition so the new tires are not immediately subjected to uneven wear.
A careful first check is especially important when the car uses 19-inch or 20-inch wheels, where profile and clearance leave less room for mistakes. After installation, watch for rubbing, vibration, or irregular wear patterns during the first miles, since those signs often reveal a setup issue that should be corrected early.
How often should tires on a 2019 Chevrolet Impala be inspected?
Tires on a 2019 Chevrolet Impala should be inspected regularly, not just when tread looks low. Pressure, tread depth, sidewall condition, punctures, and uneven wear all deserve routine attention, particularly on a car with larger wheels or a lower-profile 19-inch or 20-inch tire package.
A good habit is to check the tires before longer drives and any time the car’s ride or steering feel changes. Vehicles that sit for stretches still need inspection, since age, air loss, and unnoticed damage can build up quietly, even when mileage stays modest and the car is not driven every day.
