The 2020 Chrysler lineup was focused and unmistakably American, with the 300 carrying the brand’s full-size sedan tradition into a modern era of rear-wheel-drive proportions and upscale highway comfort. Even within that single-model range, Chrysler used four different tire sizes to support different wheel packages and trim appearances. For 2020 Chrysler vehicles, the real choice is not bias-ply versus radial or one vintage construction against another, but identifying which wheel diameter your 300 actually uses, since the available sizes span 17-, 18-, 19-, and 20-inch fitments. Confirm the model and wheel package first, then match the tire size before comparing product style, load capacity, and driving character.
Which Tire Size Is Right for Your 2020 Chrysler
Four tire sizes are used on 2020 Chrysler vehicles, and all of them apply to the Chrysler 300 rather than being shared across multiple model lines. The real decision comes down to confirming the correct wheel diameter first, since these radial sizes span four different rim diameters. Understanding that distinction before choosing a product saves time and helps ensure the right match.
Year(s): 2020|Fit(s): 300|Construction: Radial|Rim: 20 in
245/45R20 is a radial metric size with a 245-millimeter section width, a 45-series aspect ratio, and fitment for a 20-inch wheel. In this size, BFGoodrich and Nitto are available, all with blackwall styling, and speed ratings vary by product with W rated to 168 mph and Y rated to 186 mph or higher. This size is specific to certain 2020 Chrysler 300 wheel packages rather than universal across the year and make. Buyers who want the largest factory-style wheel fitment and a modern performance-oriented radial selection should start here after confirming 20-inch wheels.
Year(s): 2020|Fit(s): 300|Construction: Radial|Rim: 19-in rim
235/55R19 is a radial metric size with a 235-millimeter section width, a 55-series aspect ratio, and fitment for a 19-inch wheel. Radial construction is the defining feature of this size for the 2020 Chrysler 300, and the key first step is verifying that your car carries the 19-inch wheel package. This size is specific to 300 applications that use 19-inch rims rather than to every 2020 Chrysler fitment. It is the right path for owners matching an original 19-inch setup and then narrowing choices by product design and intended road use.
Year(s): 2020|Fit(s): 300|Construction: Radial|Rim: 17-in rim
215/65R17 is a radial metric size with a 215-millimeter section width, a 65-series aspect ratio, and fitment for a 17-inch wheel. Radial construction gives this size the modern format expected on a late-model full-size sedan, and the main fitment question is simply whether your 2020 Chrysler 300 uses the 17-inch wheel package. This size is specific to 300 applications equipped with 17-inch rims, so it is not interchangeable with the larger-diameter wheel packages without changing wheels. Owners seeking a straightforward match for a factory 17-inch setup should confirm wheel diameter first and then compare individual tire options.
Year(s): 2020|Fit(s): 300|Construction: Radial|Rim: 18-in rim
225/60R18 is a radial metric size with a 225-millimeter section width, a 60-series aspect ratio, and fitment for an 18-inch wheel. Radial construction is standard here as well, so the practical distinction is wheel diameter rather than construction style. This size is specific to 2020 Chrysler 300 applications running 18-inch wheels instead of the 17-, 19-, or 20-inch packages. It suits owners who are matching an original 18-inch fitment and want to stay with the wheel diameter their car was equipped to use.
One model is covered for 2020 Chrysler: the 300. Even with a single model line, tire size still varies across the range because the 300 was offered with multiple wheel diameters, so identifying your exact wheel package matters before choosing a tire. Select the model below for model-specific fitment history and products.
2020 Chrysler 300
The 2020 Chrysler 300 carried on as a large, traditional American sedan with a long hood, upright stance, and a strong emphasis on highway comfort and presence. Within the 300 range, tire fitment spans 17-, 18-, 19-, and 20-inch wheel packages, so the wheel diameter on the car is the key detail to confirm before narrowing down tire choices.
Four products are available across one tire size for 2020 Chrysler vehicles. The 245/45R20 size includes four radial blackwall choices from BFGoodrich and Nitto, with speed ratings that vary by product. Confirm your wheel diameter and exact size before comparing tire construction details and service ratings.
These answers focus on the four radial sizes used across the 2020 Chrysler 300, how to identify the right wheel package, and what to compare when sidewall style, speed rating, and long-term collector-style care matter.
Size Basics & Fitment
What tire sizes fit 2020 Chrysler vehicles?
2020 Chrysler vehicles use four tire sizes, all on the Chrysler 300: 215/65R17, 225/60R18, 235/55R19, and 245/45R20. These are all radial sizes, and each one matches a different wheel diameter rather than serving as a universal fit across every 300 wheel package. The 245/45R20 fits 20-inch rims with a published rim-width range of 7.5 to 9.0 inches on available products.
That means the first fitment question for a 2020 Chrysler 300 is wheel diameter, not simply year and make. If your car has 17-, 18-, 19-, or 20-inch factory wheels, the tire size needs to match that wheel exactly. Once the size is confirmed from the tire sidewall, door placard, or original wheel package, you can compare product style, service description, and brand preference with much more confidence.
What does 245/45R20 mean on a 2020 Chrysler tire?
On a 2020 Chrysler tire, 245/45R20 means the tire is 245 millimeters wide, has a 45-series aspect ratio, uses radial construction, and mounts on a 20-inch wheel. The available 245/45R20 products for the Chrysler 300 are blackwall radials from BFGoodrich and Nitto. Speed ratings in this size include W, which is rated to 168 mph, and Y, which is rated to 186 mph or higher.
That code matters because each part affects compatibility with the wheel and the tire’s general service category. A 245/45R20 cannot replace a 235/55R19 or 225/60R18 without also changing to the correct wheel diameter. For a 2020 Chrysler 300 owner, the code is the quickest way to verify whether the car is running the 20-inch package before moving on to brand, tread design, and load rating details.
Do all 2020 Chrysler models use the same tire size?
No. The 2020 Chrysler range covered here consists of the Chrysler 300, and that single model uses four different tire sizes depending on wheel package: 215/65R17, 225/60R18, 235/55R19, and 245/45R20. All four are radial sizes, but they mount on different rim diameters, so they are not directly interchangeable on the same wheel.
For a buyer, that means identifying the exact version of the 2020 Chrysler 300 is less important than identifying the wheels currently on the car. Factory wheel upgrades often changed the tire size along with the wheel diameter. Checking the sidewall on the tire already fitted, the placard on the car, or the original wheel package is the most reliable starting point before choosing a replacement.
Buying the Right Tire
What sidewall styles are available for 2020 Chrysler tires?
The available 2020 Chrysler products shown here use blackwall sidewalls in 245/45R20. That sidewall treatment suits the modern, contemporary appearance of the Chrysler 300 and aligns with how late-model sport and touring sedans are commonly equipped. No vintage-style whitewall or bias-look sidewall treatment appears within the available 20-inch selection.
For most 2020 Chrysler 300 owners, sidewall style is therefore a simple decision: blackwall keeps the car visually correct for its era and trim character. Once the appearance question is settled, the more important distinctions become speed rating, load capability, and the tread category of the tire itself. Owners trying to preserve a factory-like look should generally stay with the clean blackwall presentation used on modern full-size sedans.
What brands make tires for 2020 Chrysler vehicles?
BFGoodrich and Nitto both make tires for 2020 Chrysler vehicles in 245/45R20, the 20-inch Chrysler 300 fitment covered by current product availability. BFGoodrich appears with multiple g-Force series options as well as the g-Force Phenom T/A, while Nitto is represented by the NT555 G2. All of those choices use radial construction and blackwall styling.
That mix gives a 2020 Chrysler 300 owner more than one brand path within the same size, which is useful when comparing service description and tread intent rather than just basic fitment. BFGoodrich has long recognition in the performance street market, while Nitto is also well known among enthusiasts looking for modern radial performance character. The right choice comes down to matching the confirmed tire size first and then selecting the product profile that best suits how the car is driven.
What is the difference between BFGoodrich and Nitto options for 2020 Chrysler 245/45R20 tires?
For 2020 Chrysler 245/45R20 tires, BFGoodrich offers several choices in the g-Force family plus the g-Force Phenom T/A, while Nitto offers the NT555 G2. The BFGoodrich products carry published weights around 30 to 30.73 pounds, with rim-width guidance of 7.5 to 9.0 inches and load figures around 1929 to 1930 pounds at 50 psi where stated. The Nitto NT555 G2 carries a published weight of 30.38 pounds and a W speed rating in the same basic size category.
Those differences are subtle rather than dramatic, so most 2020 Chrysler 300 owners should use them as a comparison tool after size confirmation, not as a substitute for fitment research. If your priority is staying within a known rim-width window, the BFGoodrich specifications are more fully spelled out in the available details. If you are comparing by brand character within the same 20-inch fitment, both brands offer modern radial blackwall choices aimed at contemporary road use.
Fitting & Setup
What rim width do 2020 Chrysler tires require?
For 2020 Chrysler tires in 245/45R20, available products specify a 20-inch rim diameter and a rim-width range of 7.5 to 9.0 inches. That range appears on multiple BFGoodrich options in this size, making it a useful reference point for Chrysler 300 owners with the 20-inch wheel package. The other 2020 Chrysler sizes here use 17-, 18-, and 19-inch diameters, but a rim-width range is not stated for them in the available specifications.
Rim width matters because the correct tire size still needs an appropriate wheel width to support proper sidewall shape and tread behavior. If your 2020 Chrysler 300 runs 20-inch wheels, confirming that the wheel falls within the published width range is a smart step before installation. Owners using other factory diameters should verify wheel width from the wheel specification itself or through Chrysler service information before changing tire brands or profiles.
Do 2020 Chrysler tires require inner tubes?
The available 2020 Chrysler 245/45R20 products are modern radial tires, and one BFGoodrich option is explicitly marked TL for tubeless service. The rest of the 245/45R20 entries are modern radial passenger-car products without tube-type markings. That makes tubeless service the expected setup for the 20-inch Chrysler 300 applications covered here.
For a 2020 Chrysler owner, the practical concern is usually not adding tubes but making sure the wheel, valve stem, and bead seat are in good condition for tubeless use. Tubes should not be added casually to a modern radial application unless a manufacturer specifically calls for it. If a wheel has damage, corrosion, or a sealing issue, correct the wheel problem first rather than trying to solve it with an unnecessary tube.
Maintenance, Storage & Longevity
How should I store a 2020 Chrysler when the tires are fitted?
A 2020 Chrysler should be stored out of direct sunlight, away from ozone-producing equipment such as electric motors and battery chargers, and on a clean, dry surface. Keeping the tires properly inflated helps the sidewalls hold their intended shape during long static periods. Because these are modern radial tires rather than bias-ply designs, they generally resist temporary flat spotting better than older vintage constructions, but they still benefit from periodic movement.
If the Chrysler 300 will sit for weeks or months, move it occasionally or support it in a way that reduces long-term stress on one contact patch. Washing off road salts and keeping the tire sidewalls free of petroleum-based dressings also helps long-term rubber condition. Good storage habits matter just as much for a late-model collector sedan as they do for an older classic if you want the tires to age evenly and remain dependable.
How long do tires on a 2020 Chrysler typically last?
Tires on a 2020 Chrysler should be judged by age and condition as much as by remaining tread depth. A sensible collector and enthusiast rule is to begin close inspection once tires reach about five to seven years of age and to treat around ten years as a serious replacement point, even if mileage is low. The DOT date code on the sidewall is the best way to establish the tire’s actual age.
That approach is especially important on a Chrysler 300 that may see less use than an ordinary daily driver. A tire can look serviceable at a glance yet still harden with age, lose wet-weather grip, or develop internal deterioration. If the car has been stored indoors and driven sparingly, inspect it anyway rather than assuming low mileage guarantees a long safe life.
How often should tires on a 2020 Chrysler be inspected?
Tires on a 2020 Chrysler should be inspected before every drive and again before any longer highway outing. Check for pressure loss, sidewall cracking, cuts, punctures, bulges, unusual wear, and any vibration or pull that suggests a balance or alignment issue. On a modern tubeless Chrysler 300 setup, the valve stems and wheel sealing surfaces deserve attention along with the tire itself.
Frequent inspection is a simple habit that can prevent a minor aging or road-hazard issue from becoming a trip-ending problem. A full-size sedan like the Chrysler 300 places meaningful load on its tires, especially at interstate speeds, so small signs of deterioration are worth taking seriously. Including the spare in your inspection routine is also wise, since a neglected spare often becomes unusable when it is finally needed.
Safety & Road Use
Are 2020 Chrysler tires safe for highway driving?
Yes, 2020 Chrysler tires in the 245/45R20 fitment are modern radial products intended for contemporary road use, and available speed ratings include W and Y. W is rated to 168 mph, while Y is rated to 186 mph or higher. Those ratings sit far above normal U.S. highway speeds, so in ordinary use the tire’s speed capability is not likely to be the limiting factor on a well-maintained Chrysler 300.
Real-world highway safety depends more on choosing the correct size, maintaining proper inflation, and making sure the tire is in sound condition than on chasing the highest speed symbol. A 2020 Chrysler 300 is a modern full-size sedan, but suspension condition, brake condition, alignment, and tire age still matter greatly on longer drives. Treat the speed rating as a service-category indicator, not as an invitation to operate beyond legal or prudent speeds.
What inflation pressure should I use for 2020 Chrysler tires?
For 2020 Chrysler tires, use the vehicle manufacturer’s recommended cold inflation pressure for the exact wheel and tire package on the car, then compare that with the tire maker’s service information for the specific product. In the 245/45R20 size, available products include load figures around 1929 to 1930 pounds at 50 psi where stated, but that number reflects the tire’s rated maximum load relationship rather than the everyday operating pressure Chrysler necessarily specified for the 300.
That distinction matters because a maximum-pressure figure should not automatically be used as the target pressure for normal driving. A 17-inch Chrysler 300 package may call for a different operating pressure than a 20-inch package, even though both fit the same model line. Check the door placard or owner’s manual first, then confirm the tire’s service details so the inflation choice matches both the vehicle and the tire.
What should I check before taking a 2020 Chrysler on a longer drive?
Before taking a 2020 Chrysler on a longer drive, inspect each tire for cuts, punctures, bulges, irregular wear, exposed cords, and age-related cracking. Confirm cold pressure, make sure the valve stems are sound, and verify that the spare is usable if the car still carries one. On a Chrysler 300 with 20-inch tires, it is also wise to confirm that the wheel and tire combination still matches the correct 245/45R20 fitment if the car has ever had wheels changed.
Tire checks should be part of a broader pre-trip look at brakes, fluids, battery condition, and suspension health, especially on a heavier full-size sedan. A long highway run places more continuous heat and load into the tires than short local trips do. Catching a pressure issue or sidewall problem at home is far easier than dealing with it roadside, and it helps preserve both the car and the trip.
