The 2017 Chevrolet Impala carries the nameplate into a modern full-size sedan role, with a quieter, more substantial character than the rear-drive Impalas many enthusiasts remember from earlier decades. It is a roomy, highway-minded car, so tire choice affects both appearance and everyday road manners. This Impala uses radial fitments in either 235/50R18 or 245/45R19, depending on sub-model and wheel package. Available choices include blackwall performance-oriented radials as well as select redline and raised white letter options in 18-inch sizing. The key is confirming the exact trim and wheel diameter first, then choosing the tire style and series that best match the car's intended use.
Which Tire Size Is Right for The 2017 Chevrolet Impala
The 2017 Chevrolet Impala uses two primary tire sizes, and the correct one depends on sub-model and wheel diameter. Both are radial fitments, but 235/50R18 mounts on an 18-inch rim while 245/45R19 mounts on a 19-inch rim. Before comparing brands or sidewall styles, confirm whether the car has the 18-inch or 19-inch wheel setup and which trim level it carries.
In 235/50R18, the 235 is the nominal section width in millimeters, 50 is the aspect ratio, R identifies radial construction, and 18 is the rim diameter in inches. This is a modern radial size suited to 2017 Impala configurations that use an 18-inch wheel. Product choices in this size include BFGoodrich, Nitto, and Pro-Trac offerings, with blackwall, redline, and RWL sidewall treatments depending on the tire series. It is the right size to evaluate when the car has the 18-inch wheel package and the buyer wants to compare both conventional modern styling and more distinctive sidewall presentation.
In 245/45R19, the 245 identifies nominal section width in millimeters, 45 is the aspect ratio, R marks radial construction, and 19 indicates a 19-inch rim. This fitment applies to 2017 Impala configurations equipped with the larger 19-inch wheel. Available options in this size include BFGoodrich and Nitto tires, all in blackwall form, with series differences that matter more than sidewall styling on this application. It is the size to focus on when the car carries the 19-inch setup and the goal is staying with the proper wheel diameter while comparing the available radial tire families.
Sub-model fitment matters on the 2017 Impala because tire size is not the same across the full range. LS stays with one 18-inch size, Premier uses one 19-inch size, and LT may use either setup, so identifying the exact trim and wheel package comes first.

2017 Chevrolet Impala LS
The 2017 Chevrolet Impala LS uses the 235/50R18 radial fitment on an 18-inch wheel. Tire selection here is mostly about choosing among available radial series and sidewall treatments while keeping the correct 18-inch size in place.
The 2017 Chevrolet Impala LT can use either 235/50R18 or 245/45R19, so wheel diameter must be confirmed before a tire is selected. That makes the LT the trim where checking the actual wheel on the car matters most before comparing brands, series, or sidewall style.
The 2017 Chevrolet Impala Premier uses the 245/45R19 radial fitment on a 19-inch wheel. Tire choice centers on selecting the right 19-inch radial series and confirming wheel compatibility rather than sorting through multiple sidewall appearance options.
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.
Best 2017 Chevrolet Impala Tires for Sale
Available 2017 Chevrolet Impala tires center on 235/50R18 and 245/45R19 radial fitments from BFGoodrich, Nitto, and Pro-Trac. Buyers can compare blackwall choices across both sizes, while the 18-inch fitment also adds redline and raised white letter options for a more distinctive look.
These FAQs focus on the exact tire sizes used on the 2017 Chevrolet Impala, how fitment changes by sub-model, and what to compare when choosing between available radial tires, wheel diameters, sidewall styles, and road-use considerations.
Tire Size & Fitment
What tire size fits a 2017 Chevrolet Impala?
A 2017 Chevrolet Impala uses either 235/50R18 or 245/45R19, depending on the sub-model and wheel setup. Both are radial tire sizes, but they are built for different rim diameters, so they are not interchangeable as primary fitments without confirming the wheel on the car.
The practical first step is to identify whether the Impala has 18-inch or 19-inch wheels and then match the tire size to that wheel diameter. LS uses 235/50R18, Premier uses 245/45R19, and LT can use either size, which makes direct wheel verification especially important on that trim.
What size rim does a 2017 Chevrolet Impala use?
The 2017 Chevrolet Impala uses either an 18-inch or 19-inch rim, depending on trim and wheel package. The 235/50R18 tire fits the 18-inch setup, while the 245/45R19 tire fits the 19-inch setup.
Rim diameter is the first thing to confirm before buying tires for this Impala because the two tire sizes are tied to two different wheel diameters. An LT model deserves extra attention here, since it may be equipped with either setup, and a previous owner may also have changed wheels after the car left the factory.
Do all 2017 Chevrolet Impala sub-models use the same tire size?
No, 2017 Chevrolet Impala sub-models do not all use the same tire size. LS uses 235/50R18, Premier uses 245/45R19, and LT may use either 235/50R18 or 245/45R19 depending on the wheel package on the car.
That variation means trim identification alone is helpful, but it is not always enough for an LT. Checking the actual sidewall marking and wheel diameter prevents ordering the wrong size and keeps the comparison focused on the right product choices, sidewall styles, and rim-width specifications for the wheel already on the car.
Choosing the Right Tire
What should I consider when choosing a tire for a 2017 Chevrolet Impala?
Start with the correct primary size for the car: 235/50R18 or 245/45R19. From there, compare radial construction details that matter to ownership goals, including brand, tire series, sidewall style, rim-width specification, and load figures where they are stated.
A daily-driven Impala may call for a different choice than a car kept for occasional fair-weather use or one where appearance matters as much as road manners. Matching the tire to the actual wheel diameter, confirming wheel width, and deciding whether you want a straightforward blackwall or a more distinctive sidewall treatment are the key next steps.
What sidewall styles are available for 2017 Chevrolet Impala tires?
Sidewall choice depends on size. In 235/50R18, available styles include blackwall, redline, and RWL, while 245/45R19 options shown here are blackwall tires. That gives the 18-inch fitment more appearance variety than the 19-inch fitment.
Sidewall style does not change the need to keep the correct size and rim diameter, but it can change the overall presentation of the car. A buyer with an 18-inch Impala can choose between a more understated look and a more attention-grabbing one, while a 19-inch setup is better approached as a series-and-brand decision within blackwall radials.
What brands offer tires for the 2017 Chevrolet Impala?
BFGoodrich, Nitto, and Pro-Trac all offer tire choices for the 2017 Chevrolet Impala across its 18-inch and 19-inch fitments. BFGoodrich appears in both sizes, Nitto also spans both sizes, and Pro-Trac is represented in the 235/50R18 fitment.
Brand alone should not make the decision. It is more useful to compare the correct size first, then look at which series each brand offers, whether the sidewall style matches the look you want, and whether the wheel width on the car falls within the tire's stated compatibility range where that information is available.
Restoration & Appearance
Which tire should I choose for a period-style 2017 Chevrolet Impala?
A period-style approach on a 2017 Chevrolet Impala still begins with the correct modern radial size for the car's wheel package. Among the available options, 235/50R18 offers the broadest appearance range because it includes blackwall, redline, and RWL choices, while 245/45R19 remains a blackwall-focused fitment.
That makes the 18-inch setup the stronger candidate if appearance is part of the decision. The right choice depends on whether the goal is a subtle modern look or a more expressive presentation, but the wheel diameter and proper tire size still need to stay at the center of the selection process.
How does tire choice affect the appearance of a 2017 Chevrolet Impala?
Tire choice changes the visual character of a 2017 Chevrolet Impala more through sidewall treatment and wheel size than through construction, since both primary fitments are radial. A blackwall keeps the look understated, while redline or raised white letter styling on 235/50R18 adds a much stronger visual statement.
The car's trim and wheel package shape that decision. An LS or 18-inch LT has more room for appearance-driven sidewall selection, while a Premier or 19-inch LT is more about choosing among blackwall radial series that preserve the proper fitment and support the car's larger-wheel presentation.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2017 Chevrolet Impala?
Yes, modifications can affect tire fitment on a 2017 Chevrolet Impala. Changes such as aftermarket wheels, altered wheel width, different offset, suspension lowering, or body modifications can all change how a 235/50R18 or 245/45R19 tire sits in the wheel opening.
A modified Impala should be checked for actual wheel diameter, wheel width, and clearance at full steering lock and through suspension travel before a new tire is chosen. Even when the sidewall size matches one of the original fitments, the wheel and chassis setup may no longer mirror a standard LS, LT, or Premier configuration.
What should I inspect before driving a 2017 Chevrolet Impala on new tires?
Before driving a 2017 Chevrolet Impala on new tires, inspect the wheels for damage, confirm the tire size matches the wheel diameter, and make sure inflation is set correctly for the car's use. It is also wise to check for any rubbing at the fenders, liners, or steering components.
A short local drive is a good way to confirm that the tires seat and track properly before putting the car into regular service. Rechecking pressure after installation, listening for contact noises, and verifying that the tires clear during parking-lot turns can catch small fitment issues before they become larger problems.
How often should tires on a 2017 Chevrolet Impala be inspected?
Tires on a 2017 Chevrolet Impala should be inspected regularly, not just when tread looks low. Look at them before longer drives and during routine maintenance for uneven wear, cuts, cracking, bulges, and any steady loss of air pressure.
That habit matters whether the car is driven daily or sits for longer periods. An Impala that sees less use can still develop age-related condition problems, while a frequently driven one may show alignment or suspension issues through wear patterns. Checking the sidewalls and tread often helps catch problems before they affect ride quality or road confidence.
