The 2020 Chrysler 300 carried one of the last traditional full-size American sedan formulas into the modern era, blending rear-wheel-drive proportions, available all-wheel drive, and a distinctly formal look that sets it apart from more anonymous contemporary cars. Tire selection on this model is more configuration-specific than it first appears, with four primary radial sizes used across the lineup: 215/65R17, 225/60R18, 235/55R19, and 245/45R20. That makes the first step identifying the exact sub-model and wheel diameter before comparing tire choices. For 245/45R20 applications, available options also bring meaningful sidewall and series differences, including Blackwall, Redline, and raised white letter styling. Buyers balancing appearance, road manners, and correct fitment should verify the actual wheel setup before choosing a replacement.
Which Tire Size Is Right for The 2020 Chrysler 300
The 2020 Chrysler 300 uses four primary tire sizes, and the right one depends on the exact sub-model and wheel diameter. All of them are radial fitments, but they are spread across 17-inch, 18-inch, 19-inch, and 20-inch rims, so confirming the specific trim and the actual wheels on the car is the first step before comparing tire styles or product options.
Fit(s): C (RWD), Limited (RWD), S (RWD), Touring (RWD), and Touring L (RWD)
Construction: Radial|Rim: 20 in
245/45R20 is a metric radial size with a 245-millimeter nominal section width, a 45-series aspect ratio, and fitment for a 20-inch wheel. On the 2020 Chrysler 300, this size is used on several rear-wheel-drive configurations and gives the buyer the broadest visible product choice within this fitment. Available options include BFGoodrich, Nitto, and Pro-Trac products, along with Blackwall, Redline, and raised white letter sidewall treatments across series such as g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, Nitto NT555 G2, and Street Pro III. This is the size to evaluate carefully when appearance and tire character both matter.
Fit(s): Limited (AWD), S (AWD), Touring (AWD), and Touring L (AWD)
Construction: Radial|Rim: 19 in
235/55R19 is a metric radial size that uses a 235-millimeter nominal section width, a 55-series profile, and a 19-inch rim. On the 2020 Chrysler 300, this size is tied to several all-wheel-drive sub-models rather than the lineup as a whole. Its role is straightforward from a fitment standpoint, but it still needs to match the actual wheel package on the car. Buyers selecting this size should focus first on confirming the AWD configuration and 19-inch wheel setup, then move on to normal replacement considerations such as construction consistency, wheel compatibility, and intended road use.
215/65R17 is a metric radial size with a 215-millimeter nominal section width, a 65-series aspect ratio, and fitment on a 17-inch wheel. For the 2020 Chrysler 300, this size appears on a Touring RWD configuration and represents one of the smaller wheel-and-tire packages used within the model range. The size format is familiar to modern buyers, but it still serves a specific application rather than every 300. This fitment should be chosen only after confirming that the car actually carries the 17-inch wheel package, especially on vehicles that may have been upgraded or changed from their original wheel setup.
225/60R18 is a metric radial size that combines a 225-millimeter nominal section width with a 60-series profile on an 18-inch rim. On the 2020 Chrysler 300, it is used on certain rear-wheel-drive Touring and Touring L configurations, placing it between the 17-inch and 20-inch fitments in the lineup. That makes it important to treat as its own specific wheel package rather than as a general Chrysler 300 size. Buyers considering this fitment should confirm the exact sub-model and 18-inch wheel diameter first, then compare replacement tires with attention to proper wheel compatibility and overall vehicle setup.
Tire fitment on the 2020 Chrysler 300 varies meaningfully by sub-model, drivetrain, and wheel package rather than staying consistent across the lineup. Checking the exact trim and whether the car is RWD or AWD matters just as much as reading the tire sidewall, especially on Touring and Touring L models with more than one size possibility.

2020 Chrysler 300 C (RWD)
The 2020 Chrysler 300 C (RWD) uses the 245/45R20 radial fitment. That points the tire decision toward 20-inch replacement choices, where sidewall style and tire series become part of the selection process alongside straightforward size matching.
The 2020 Chrysler 300 Limited (AWD) uses the 235/55R19 radial size. Tire selection here is mainly about confirming the 19-inch AWD wheel package and choosing a replacement that matches the vehicle's actual wheel setup and intended road use.
The 2020 Chrysler 300 Limited (RWD) uses the 245/45R20 radial fitment. That gives this sub-model the same basic sizing path as other 20-inch rear-wheel-drive 300s, making product style, brand, and sidewall presentation more relevant once the wheel diameter is confirmed.
The 2020 Chrysler 300 S (AWD) uses the 235/55R19 radial size. Buyers should treat this as a specific 19-inch AWD fitment and verify the actual wheels on the car before comparing replacement tires or considering any size change.
The 2020 Chrysler 300 S (RWD) uses the 245/45R20 radial fitment. Once that 20-inch setup is confirmed, the decision becomes less about size identification and more about choosing among the available tire series and sidewall styles that suit the car's look and use.
The 2020 Chrysler 300 Touring (AWD) uses the 235/55R19 radial size. That keeps fitment straightforward as long as the car still carries its 19-inch wheel package, which is worth checking on any vehicle that may have seen wheel changes.
The 2020 Chrysler 300 Touring (RWD) can use more than one tire size, so this is the sub-model where wheel confirmation matters most. Tire selection starts with identifying whether the car has the 17-inch, 18-inch, or 20-inch setup before moving on to replacement style and product choice.
The 2020 Chrysler 300 Touring L (AWD) uses the 235/55R19 radial fitment. Buyers should confirm the 19-inch AWD wheel package first, then focus on selecting a modern radial replacement that matches the vehicle's current wheels and intended driving use.
The 2020 Chrysler 300 Touring L (RWD) can use more than one tire size depending on the wheel package. That means the right replacement begins with confirming whether the car has the 18-inch or 20-inch setup, since both sizing and available tire presentation can change with the wheel diameter.
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.

The most useful questions for a 2020 Chrysler 300 usually come down to identifying the correct tire size by sub-model, confirming wheel diameter, and understanding how available 245/45R20 products differ by brand, series, and sidewall style.
Tire Size & Fitment
What tire size fits a 2020 Chrysler 300?
The 2020 Chrysler 300 uses four primary tire sizes: 215/65R17, 225/60R18, 235/55R19, and 245/45R20. All are radial sizes, but they do not apply across every version of the car. The correct fitment depends on the exact sub-model, drivetrain, and wheel package.
The practical first step is matching the tire size to the actual wheels on the car, not just the model name on the trunk. Touring and Touring L configurations can overlap with more than one wheel package, so checking the existing sidewall and confirming rim diameter helps prevent choosing a tire for the wrong setup.
What size rim does a 2020 Chrysler 300 use?
A 2020 Chrysler 300 can use 17-inch, 18-inch, 19-inch, or 20-inch rims depending on the sub-model and wheel package. Those rim diameters correspond to the four primary tire sizes used on the car, so wheel diameter is a direct part of tire fitment rather than a separate detail.
Reading the last number in the tire size is the quickest confirmation point: 17 in 215/65R17, 18 in 225/60R18, 19 in 235/55R19, and 20 in 245/45R20. Any replacement tire needs to match the wheel diameter already on the vehicle unless the wheels themselves are being changed as part of a complete fitment plan.
Why does the 2020 Chrysler 300 have more than one tire size?
The 2020 Chrysler 300 uses more than one tire size because the lineup includes different trims, drivetrains, and wheel packages. AWD models commonly use 235/55R19, while several RWD versions use 245/45R20, and Touring-based RWD configurations can also appear with 215/65R17 or 225/60R18.
That variation means the right replacement is determined by the exact car in front of you, not by assuming every 300 uses the same tire. Looking at the door-jamb placard, the existing tire sidewall, and the actual wheel diameter is especially important on cars that may have had dealer, aftermarket, or owner-installed wheel changes.
Choosing the Right Tire
What should I consider when choosing a 245/45R20 tire for a 2020 Chrysler 300?
Start with the basics: the tire needs to be the correct 245/45R20 size for a 20-inch wheel and suited to the car's actual wheel width. Within that fitment, available products vary by brand, tire series, sidewall style, and in some cases details such as stated load figures or wheel-width compatibility ranges.
The best way to narrow the choice is to decide what matters most on the car. Some owners will want a straightforward Blackwall look, while others may prefer Redline or raised white letter styling for a more customized presentation. It also helps to compare the wheel-width specification of the tire against the wheels currently on the vehicle.
What sidewall styles are available for 2020 Chrysler 300 tires?
For 245/45R20 applications on the 2020 Chrysler 300, available sidewall styles include Blackwall, Redline, and RWL, which is raised white letter. Those options appear within radial products, so the difference is primarily visual rather than a change from one basic construction type to another.
That makes sidewall style a useful way to tailor the appearance of the car once the correct size is confirmed. Blackwall keeps the presentation restrained and modern, while Redline or raised white letters create a more assertive look. The key is choosing the style within the correct 20-inch fitment rather than treating appearance as separate from proper sizing.
What brands offer tires for the 2020 Chrysler 300?
The 245/45R20 fitment for the 2020 Chrysler 300 is available from BFGoodrich, Nitto, and Pro-Trac. Those brands cover several different radial series, including 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 matters most after the fitment details are settled. Once the correct size, wheel diameter, and wheel-width compatibility are confirmed, the decision usually comes down to the kind of presentation and tire character you want. Comparing series names, sidewall styling, and published fitment specifications is more useful than trying to rank one brand universally over another.
Restoration & Appearance
Which tire should I choose for a period-style 2020 Chrysler 300?
A period-style approach on a 2020 Chrysler 300 starts with using the correct size for the exact sub-model and wheel package, then choosing a tire whose sidewall presentation suits the car's look. On 245/45R20 applications, that may mean comparing Blackwall, Redline, or raised white letter options within the available radial selections.
Since this is a modern sedan rather than an earlier collector-era car, appearance is usually more about preserving the character of the wheel-and-tire package than chasing strict originality. The smartest approach is to confirm the current wheels first, then choose a sidewall style and tire series that support the way the car is being kept and driven.
How does tire construction affect the appearance of a restored 2020 Chrysler 300?
On the 2020 Chrysler 300, tire construction is straightforward because the primary fitments are radial. That means the visual difference is less about bias-ply versus radial and more about the tire's sidewall style, tread presentation, and how the chosen series complements the wheel package on the car.
For an owner refreshing the car's appearance, the more important decision is usually whether to keep a clean Blackwall look or choose something more expressive such as Redline or raised white letters on a 245/45R20 setup. Size accuracy still comes first, because the right visual effect depends on the tire matching the intended wheel diameter and proportions.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 Chrysler 300?
Yes. Wheel changes, altered offsets, suspension lowering, and other modifications can all affect tire fitment on a 2020 Chrysler 300, even when the tire size itself sounds close to stock. That matters especially on a model that already uses several different factory wheel diameters across the lineup.
A car with aftermarket wheels should be checked for actual rim diameter, width, and clearance at the fender and steering components before replacing tires. Modified suspension height can also change how much room the tire has under compression or at full lock, so fitment should be verified on the car rather than assumed from the model year alone.
What should I inspect before driving a 2020 Chrysler 300 on new tires?
Before driving a 2020 Chrysler 300 on new tires, inspect the wheels for the correct diameter and condition, confirm proper air pressure, and look over the valve stems and lug hardware. It also helps to make sure the tire size matches the sub-model and wheel package the car is actually using.
A short post-installation check is just as important. Watch for rubbing during turns, listen for unusual contact noises, and recheck pressure after the first drives. On any car that has sat for a while or has changed hands, it is also smart to inspect alignment-related wear patterns and confirm that all four tires belong to the intended setup.
How often should tires on a 2020 Chrysler 300 be inspected?
Tires on a 2020 Chrysler 300 should be inspected regularly, not only when tread looks worn. A quick visual check every few weeks and a more careful inspection before longer drives helps catch uneven wear, low pressure, cuts, bulges, or sidewall damage before they become larger problems.
Cars that see irregular use deserve even closer attention because time and storage conditions can matter as much as mileage. Checking pressure, looking for age-related deterioration, and watching for air loss are especially worthwhile on a sedan that may alternate between daily use and longer parked periods. Consistent inspection also helps confirm the tires are wearing evenly across the wheel setup.
