The 2014 Chevrolet Impala marked a major shift for Chevrolet’s full-size sedan, with a more upscale design, larger footprint, and trim structure that gave the car a noticeably broader personality from practical daily driver to more appearance-focused touring sedan. That matters when choosing tires, because this Impala uses three different primary radial sizes: 235/50R18, 245/45R19, and 245/40R20. The right choice depends on the exact sub-model and wheel diameter, not just the model name on the trunk. Available options also vary by brand, tire series, and sidewall treatment, including blackwall, redline, and raised white letter styles. Before selecting a set, confirm the car’s trim and actual wheel setup, especially if it has been changed from stock.
Which Tire Size Is Right for The 2014 Chevrolet Impala
The 2014 Chevrolet Impala uses three primary tire sizes, and the correct one depends on sub-model and wheel diameter. Eco and LS models use 18-inch fitment, LT models can use either 18-inch or 19-inch tires, and LTZ models use 19-inch or 20-inch fitment. The first step is confirming the exact trim and measuring the wheels currently on the car, especially if it has aftermarket replacements.
235/50R18 is a modern metric radial size in which 235 identifies the section width in millimeters, 50 is the aspect ratio, R indicates radial construction, and 18 is the rim diameter in inches. On the 2014 Chevrolet Impala, this size serves the 18-inch wheel fitment used on Eco and LS models and on some LT applications. Product choices include BFGoodrich, Nitto, and Pro-Trac, with blackwall, redline, and RWL sidewall styles depending on the tire series. This size is the right place to start when the car retains its 18-inch wheel setup and you want to compare appearance and performance-oriented radial options within that fitment.
245/45R19 is a metric radial size that uses a 245-millimeter nominal width, a 45-series profile, and a 19-inch rim diameter. For the 2014 Chevrolet Impala, this size applies to certain LT and LTZ configurations, making it a trim-dependent choice rather than a universal fitment across the model line. Available products in this size come from BFGoodrich and Nitto, with blackwall styling across several tire series. It is a useful fitment to evaluate when the car is equipped with 19-inch wheels and the goal is to stay within the proper size range for that specific wheel package.
245/40R20 is a metric radial size where 245 is the nominal section width in millimeters, 40 is the aspect ratio, and 20 designates the wheel diameter in inches. On the 2014 Chevrolet Impala, this size belongs to the 20-inch fitment used on LTZ applications, so wheel confirmation is essential before choosing it. The available selection includes BFGoodrich, Nitto, and Pro-Trac options, with blackwall, redline, and RWL sidewall treatments depending on the tire series. This size makes the most sense when the Impala already carries the correct 20-inch wheels and you want to compare both conventional blackwall and more visually distinctive sidewall styles.
Tire fitment for the 2014 Chevrolet Impala varies by sub-model, so the trim badge matters before anything else. Some versions use a single wheel and tire package, while LT and LTZ models span more than one size, making wheel confirmation especially important.

2014 Chevrolet Impala Eco
The 2014 Chevrolet Impala Eco uses the 235/50R18 radial size. That keeps tire selection relatively straightforward, with the main decision centered on brand, tire series, and whether a blackwall, redline, or raised white letter presentation better suits the car.
The 2014 Chevrolet Impala LS also uses the 235/50R18 radial size. For an LS, the focus shifts from determining fitment to comparing the available radial choices within that size and confirming the wheels have not been changed from the original 18-inch format.
The 2014 Chevrolet Impala LT can use either 235/50R18 or 245/45R19, depending on the wheel package. That makes the LT the trim where checking the actual rim diameter is just as important as knowing the model name before choosing tires.
The 2014 Chevrolet Impala LTZ uses larger wheel fitments, with 245/45R19 or 245/40R20 depending on the setup. Tire selection for an LTZ starts with confirming which wheel diameter is on the car, then narrowing the choice by sidewall style, brand, and tire series.
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 2014 Chevrolet Impala?
The 2014 Chevrolet Impala uses three primary tire sizes: 235/50R18, 245/45R19, and 245/40R20. The correct size depends on the sub-model and wheel package. Eco and LS models use 235/50R18, LT models can use 235/50R18 or 245/45R19, and LTZ models use 245/45R19 or 245/40R20.
Choosing the right tire starts with confirming the trim and the wheel diameter actually on the car. Many fitment mistakes happen when an LT or LTZ has a different wheel package than expected, or when wheels have been changed. Checking the sidewall on the current tire and measuring the wheel diameter will keep the replacement process on track.
What size rim does a 2014 Chevrolet Impala use?
A 2014 Chevrolet Impala can use 18-inch, 19-inch, or 20-inch rims, depending on the sub-model and wheel package. The 235/50R18 tire mounts on an 18-inch rim, 245/45R19 uses a 19-inch rim, and 245/40R20 uses a 20-inch rim.
Rim diameter is the first fitment detail to confirm because the tire must match it exactly. An LT or LTZ may have more than one possible wheel size, so relying on the model name alone is not enough. It also helps to confirm wheel width when comparing tire options, especially if the car has aftermarket or replacement wheels.
Why does the 2014 Chevrolet Impala have more than one tire size?
The 2014 Chevrolet Impala has more than one tire size because different sub-models and wheel packages were used across the lineup. Eco and LS models use 235/50R18, LT models can use either 235/50R18 or 245/45R19, and LTZ models use 245/45R19 or 245/40R20.
That means the right replacement is tied to the exact version of the car and its actual wheels. The sizes are all radial, but they are not interchangeable simply because they belong to the same model year. Before choosing a tire, confirm the current wheel diameter and verify there is no mismatch from a previous wheel or suspension change.
Choosing the Right Tire
What should I consider when choosing a tire for a 2014 Chevrolet Impala?
Start with the correct tire size for the specific 2014 Chevrolet Impala sub-model and wheel diameter. From there, compare construction, sidewall style, tire series, and wheel-width compatibility where it is stated. The available lineup is entirely radial, so the decision is less about bias-ply versus radial and more about choosing the right tire character within the proper size.
A practical choice depends on how the car is used and how you want it to look. Blackwall options keep a modern appearance, while redline and RWL choices add more visual emphasis on applicable sizes. It also helps to compare load figures, tire weight, and wheel-width range when those details are available for the size you need.
What sidewall styles are available for 2014 Chevrolet Impala tires?
Sidewall choices for the 2014 Chevrolet Impala include blackwall, redline, and RWL on applicable sizes. Blackwall is available across all three primary sizes, while redline and RWL appear in selected 18-inch and 20-inch fitments through Pro-Trac Street Pro III offerings.
The sidewall does not change the basic size requirement, but it does shape the car’s appearance. A blackwall keeps the presentation understated and contemporary, while redline or raised white letters create a stronger visual accent. Before choosing a style-driven option, make sure it is offered in the exact size and rim diameter your Impala uses.
What brands offer tires for the 2014 Chevrolet Impala?
The 2014 Chevrolet Impala has tire options from BFGoodrich, Nitto, and Pro-Trac, depending on size. BFGoodrich appears across all three primary fitments through g-Force and Phenom T/A series, Nitto covers all three sizes with the NT555 G2, and Pro-Trac offers style-focused options in selected 18-inch and 20-inch sizes.
Brand choice should come after size and wheel confirmation, not before. Once the correct fitment is settled, compare the available series, sidewall treatment, and any published wheel-width or load details for that size. That approach keeps the decision centered on proper fitment and intended use instead of picking by brand name alone.
Restoration & Appearance
Which tire should I choose for a period-style 2014 Chevrolet Impala?
A period-style 2014 Chevrolet Impala tire choice still begins with the correct factory-era size for the car’s trim and wheel diameter: 235/50R18, 245/45R19, or 245/40R20. Since this is a modern full-size sedan with radial fitment, the appearance decision is usually about sidewall style and tire series rather than reproducing an older bias-ply look.
Blackwall tires maintain a cleaner, more contemporary presentation, while redline and RWL options add more personality on sizes where they are offered. Owners aiming for a presentation that matches the car’s original showroom era should also compare wheel design and trim level details, since those visual cues affect the finished look as much as the tire itself.
How does tire construction affect the appearance of a restored 2014 Chevrolet Impala?
Tire construction has less visual impact on a 2014 Chevrolet Impala than it would on an older collector car because the Impala uses modern radial sizes throughout. The visible difference comes more from profile, wheel diameter, and sidewall treatment than from switching between construction types.
For a clean restoration-oriented presentation, keeping the right size for the trim and wheel package matters most. A low-profile 20-inch setup gives the car a different stance than an 18-inch fitment, even though both are correct for certain versions. Sidewall style then becomes the finishing touch, especially where redline or RWL options are available.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2014 Chevrolet Impala?
Yes, modifications can affect tire fitment on a 2014 Chevrolet Impala. Wheel changes, altered wheel width, different offset, suspension lowering, or body modifications can all change how a 235/50R18, 245/45R19, or 245/40R20 tire sits in the wheel opening and how much clearance it has while turning or under compression.
A car that no longer has its original wheel setup should be checked carefully before ordering replacement tires. Confirm the actual rim diameter and width, then inspect inner and outer clearance around the tire. Even when the nominal size matches a known Impala fitment, a modified wheel or suspension setup can change what works safely on the car.
What should I inspect before driving a 2014 Chevrolet Impala on new tires?
Before driving a 2014 Chevrolet Impala on new tires, inspect the wheel diameter, wheel condition, and clearance at full steering lock. It is also wise to verify air pressure, look for any suspension wear that could affect tire wear, and make sure the lug hardware is correct and properly tightened.
A short initial road test can help confirm there is no rubbing, vibration, or pull once the new tires are mounted. Recheck pressure after the first few drives and look over the tread for any unusual wear pattern. That early inspection is especially important if the Impala has replacement wheels or has sat unused for long periods.
How often should tires on a 2014 Chevrolet Impala be inspected?
Tires on a 2014 Chevrolet Impala should be inspected regularly, even if the car is not driven every day. Check tread wear, air pressure, cracking, cuts, bulges, and any signs of irregular wear at routine intervals and before longer trips. A low-use car can still develop age-related tire issues despite limited mileage.
Frequent inspection matters because this Impala uses lower-profile radial sizes that depend on proper inflation and sound suspension condition. Pressure loss, curb damage, and alignment issues can show up quickly in the tread. Looking over the tires while the car is parked and again before road use helps catch problems before they become a fitment or safety concern.
