The 2019 Chrysler lineup was far more focused than the brand’s broad sedan-and-minivan years, with the 300 carrying Chrysler’s full-size rear-drive tradition into the modern era. That gives 2019 Chrysler buyers a simpler model picture, but tire choice still matters because the 300 used four distinct radial sizes depending on wheel package and trim direction. Every size belongs to the same model rather than being shared across multiple Chrysler nameplates, so the real task is matching your car to its exact wheel diameter and tire code. Before choosing a tire, confirm whether your 2019 Chrysler 300 is on 17-, 18-, 19-, or 20-inch wheels and then narrow the options from there.
Which Tire Size Is Right for Your 2019 Chrysler
Four tire sizes are used on 2019 Chrysler vehicles, and all of them belong to the Chrysler 300 rather than being shared across a wider model range. Because every size is a radial and the rim diameters differ, the real decision starts with confirming whether your car has 17-, 18-, 19-, or 20-inch wheels. Understanding that distinction before choosing a product saves time and helps ensure the right match.
Year(s): 2019|Fit(s): 300|Construction: Radial|Rim: 20 in
245/45R20 is a metric radial size with a 245-millimeter section width, a 45-series aspect ratio, and fitment for a 20-inch wheel. This size is available from BFGoodrich and Nitto in Blackwall form, with speed ratings that vary by product between W and Y. Because it is specific to certain 2019 Chrysler 300 wheel packages rather than universal across the year and make, this size should be chosen only after confirming the 20-inch wheel on the car. It suits buyers who want the modern response and road manners expected from a contemporary radial performance tire.
Year(s): 2019|Fit(s): 300|Construction: Radial|Rim: 19-in rim
235/55R19 is a metric radial size with a 235-millimeter section width, a 55-series aspect ratio, and fitment for a 19-inch wheel. Radial construction defines the fitment here, though brand, sidewall style, and speed-rating detail should be confirmed at the product level for this size. This size is specific to 2019 Chrysler 300 applications that use 19-inch wheels, so it is not interchangeable with the 17-, 18-, or 20-inch fitments without a wheel change. It is the right path for a buyer restoring or maintaining a 300 already equipped with the corresponding 19-inch setup.
Year(s): 2019|Fit(s): 300|Construction: Radial|Rim: 17-in rim
215/65R17 is a metric radial size with a 215-millimeter section width, a 65-series aspect ratio, and fitment for a 17-inch wheel. Radial construction defines the fitment here, while brand, sidewall style, and any speed-rating details depend on the exact product chosen in this size. This size is specific to 2019 Chrysler 300 versions running 17-inch wheels rather than the larger wheel packages used elsewhere in the range. It is the correct choice when preserving the intended fitment of a 300 equipped with the smaller-diameter factory wheel setup.
Year(s): 2019|Fit(s): 300|Construction: Radial|Rim: 18-in rim
225/60R18 is a metric radial size with a 225-millimeter section width, a 60-series aspect ratio, and fitment for an 18-inch wheel. Radial construction is standard in this size, while specific brand, sidewall style, and speed-rating choices should be checked on the individual tire. This size is specific to 2019 Chrysler 300 applications using 18-inch wheels, so it should not be selected simply because it is close in overall profile to another 300 size. It is best for buyers matching an existing 18-inch wheel package and keeping the car aligned with its intended fitment.
One model is covered for 2019 Chrysler: the Chrysler 300. Even with a single model, tire size still varies across the range because the 300 was offered with multiple wheel diameters, so identifying your exact setup matters before choosing a tire. Select the model below for model-specific fitment history and products.
2019 Chrysler 300
The 2019 Chrysler 300 remained Chrysler’s full-size sedan, carrying a traditional long-wheelbase, rear-drive American touring character that set it apart from many front-drive modern sedans. Its tire fitments span 17-, 18-, 19-, and 20-inch wheels, reflecting the difference between comfort-oriented and appearance-oriented wheel packages within the same model line.
Four products are available across one tire size for 2019 Chrysler vehicles. The 245/45R20 fitment has four radial choices from BFGoodrich and Nitto, all in Blackwall styling. Confirm your exact wheel size before selecting, since the 300 also uses 17-, 18-, and 19-inch fitments.
These answers focus on how the 2019 Chrysler 300’s four wheel-and-tire combinations relate to each other, what the metric size codes mean, and what to verify before replacing tires on a modern full-size Chrysler sedan.
Size Basics & Fitment
What tire sizes fit 2019 Chrysler vehicles?
2019 Chrysler fitment centers on the Chrysler 300, which uses four tire sizes: 215/65R17, 225/60R18, 235/55R19, and 245/45R20. Each size is a radial, and each mounts to the wheel diameter named at the end of the code: 17, 18, 19, or 20 inches. For the 245/45R20, the compatible rim width range runs from 7.5 to 9.0 inches across the available products.
The practical takeaway is that year and make alone are not enough for a replacement decision on a 2019 Chrysler 300. Two cars that look similar can still use different wheel packages, so the safest starting point is the existing sidewall code or a direct wheel measurement. Once the wheel diameter is confirmed, the correct tire size usually becomes straightforward.
What does 245/45R20 mean on a 2019 Chrysler tire?
On a 2019 Chrysler 300, 245/45R20 is a metric radial size. The 245 is the nominal section width in millimeters, 45 is the aspect ratio, the R means radial construction, and 20 is the wheel diameter in inches. Available products in this size carry W and Y speed ratings, with W rated to 168 mph and Y rated to 186 mph.
That code matters because it combines the tire’s width, sidewall proportion, construction, and wheel size in one line. Changing any part of it can affect fitment, appearance, and the way the car sits on the road. On a 2019 Chrysler 300, the 245/45R20 size should be matched to a true 20-inch wheel rather than treated as interchangeable with the 17-, 18-, or 19-inch options.
Do all 2019 Chrysler models use the same tire size?
No. For 2019 Chrysler, the Chrysler 300 is the model in view, and it 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 are tied to different wheel diameters rather than being one universal fitment for every 300.
That means a buyer should identify the exact wheel and tire combination on the car before choosing a replacement. Looking only at the model name can lead to the right brand in the wrong size. Checking the sidewall on the current tire or verifying the wheel diameter first is usually faster than sorting by trim names alone.
Buying the Right Tire
What sidewall styles are available for 2019 Chrysler tires?
The available 245/45R20 tires for 2019 Chrysler 300 applications are Blackwall radials from BFGoodrich and Nitto. That sidewall treatment suits the modern character of a late-model full-size sedan and keeps the appearance clean and contemporary. No alternate sidewall treatment appears in the available 20-inch products.
For most 2019 Chrysler 300 owners, that means the decision is less about period-correct sidewall styling and more about selecting the right size and performance category within a modern radial tire. If appearance matters, Blackwall maintains the understated factory-era look associated with contemporary sedans. The better comparison point is your wheel package and intended use, not a wide-white or vintage-style visual choice.
What brands make tires for 2019 Chrysler vehicles?
BFGoodrich and Nitto both cover the 245/45R20 fitment used on some 2019 Chrysler 300 applications. BFGoodrich appears in multiple series, including g-Force Sport Comp 2, g-Force Comp 2 A/S, and g-Force Phenom T/A, while Nitto covers the size with the NT555 G2. All of these are radial Blackwall tires.
Brand choice on a 2019 Chrysler 300 usually comes down to the character of the tire line you want within the correct size, rather than a difference in basic fitment. Sticking with a known performance-oriented brand family can make comparison easier when you are balancing everyday use, seasonal expectations, and the look you want on the car. The key is to narrow the search to the exact tire code first.
What is the difference between BFGoodrich and Nitto options for the 2019 Chrysler 300 in 245/45R20?
In 245/45R20 for the 2019 Chrysler 300, BFGoodrich covers the size with several g-Force variants and the g-Force Phenom T/A, while Nitto offers the NT555 G2. The BFGoodrich and Nitto products all use Blackwall radial construction, and the recorded weights cluster closely around 30 pounds. BFGoodrich products in this size also show a 7.5-to-9.0-inch rim width range, giving a clear wheel-width reference point.
That makes the comparison more about tire family and intended character than about a dramatic difference in fitment envelope. A buyer choosing among them should compare the exact series, speed rating, and use pattern rather than assuming all 245/45R20 tires in this group are identical. When two products share the same nominal size, the finer details become the deciding factors.
Fitting & Setup
What rim width do 2019 Chrysler tires require?
For the 2019 Chrysler 300 in 245/45R20, the available tires fit 20-inch wheels with a rim width range of 7.5 to 9.0 inches. That range appears consistently across the BFGoodrich products in this size and aligns with the tire’s intended wheel fitment envelope. The other 2019 Chrysler 300 sizes use different wheel diameters, so they should be matched to their own correct wheel packages.
Rim width matters because the same wheel diameter alone does not guarantee an ideal tire fit. A tire mounted on a wheel outside its intended width range can change sidewall shape and affect steering feel or tread behavior. If your 2019 Chrysler 300 has aftermarket wheels, verify both diameter and width before replacing the tires.
Do 2019 Chrysler tires require inner tubes?
The available 245/45R20 products for 2019 Chrysler 300 applications are tubeless radials. One BFGoodrich product explicitly carries a TL marker, and the rest are modern radial fitments in the same category rather than tube-type collector sizes. Nothing about these 20-inch offerings suggests an inner-tube requirement under normal modern wheel use.
That said, the wheel itself still needs to be in proper condition, with clean bead seats and sound valve hardware. If a 2019 Chrysler 300 has custom or damaged wheels, the wheel condition can matter as much as the tire specification. Tube use should never be assumed as a fix for an air-leak problem on a modern tubeless application without expert evaluation.
Can the original 2019 Chrysler wheels be used with all tire sizes?
No, not across all four sizes. The 2019 Chrysler 300 uses 215/65R17, 225/60R18, 235/55R19, and 245/45R20, and each one is built around a different wheel diameter. A 20-inch tire cannot be mounted on an 18-inch wheel, and the same rule applies across the rest of the range.
Original wheels can be reused when the tire size matches the wheel diameter and width requirements for that specific setup. That is why wheel confirmation comes first on a 2019 Chrysler 300 with uncertain history or aftermarket changes. If the car has changed hands or had wheel swaps, inspect the actual wheel rather than relying only on trim assumptions.
Maintenance, Storage & Longevity
How should I store a 2019 Chrysler when the tires are fitted?
A 2019 Chrysler 300 stores best on clean, properly inflated tires in a cool, dry space away from direct sun, electric motors, welders, battery chargers, and other ozone-producing equipment. Even modern radials age faster when they sit under low pressure or in strong UV exposure. Rolling the car periodically helps reduce long static loading on one contact patch.
For longer storage, many owners either move the car occasionally or support it in a way that reduces continuous load while still protecting the suspension and chassis. Tire covers and a stable indoor environment are useful if the car is part of a low-use collection. Good storage habits preserve sidewall condition and help the car feel more predictable when it returns to the road.
How long do tires on a 2019 Chrysler typically last?
On a 2019 Chrysler 300, tire life should be judged by age and condition as much as by tread depth. A useful rule is to begin close inspection around five to seven years of service and to treat about ten years from the date code as a serious replacement point, even if the car has been driven sparingly. Collector and low-mileage cars often age out their tires before they wear them out.
That matters because a full-size sedan can still look fine on old tires while the rubber hardens internally. Checking the DOT date code, sidewall condition, and ride quality is often more revealing than mileage alone. If a 2019 Chrysler has spent long stretches parked, age-based evaluation becomes even more important than it would on a daily driver.
How often should tires on a 2019 Chrysler be inspected?
Tires on a 2019 Chrysler 300 should be inspected before every drive and more carefully before any longer trip. Look for cracking, bulges, punctures, uneven wear, and pressure loss, and check that the tread is wearing consistently across the tire. Modern radial construction is durable, but pressure and condition still affect the way a heavy sedan behaves at speed.
A quick visual check catches many problems before they become roadside issues. For a car that sees occasional use, monthly pressure checks and seasonal inspections are a sensible baseline, with extra attention after storage or after hitting potholes. If the steering feel changes or the car begins to pull, inspect the tires before assuming the problem is elsewhere.
Safety & Road Use
Are 2019 Chrysler tires safe for highway driving?
Yes, the radial tires used on the 2019 Chrysler 300 are built for modern road use, and the available 245/45R20 products carry W and Y speed ratings. That means ceilings of 168 mph for W and 186 mph for Y, which far exceed normal highway operation. In everyday use, the car’s alignment, tire condition, inflation, and overall mechanical health matter more than the theoretical speed ceiling.
Highway safety on a 2019 Chrysler 300 depends on matching the exact tire size to the wheel and keeping the tire in good condition. A fresh, properly inflated tire with the correct load capability is more meaningful than choosing a higher speed rating for bragging rights. On a modern Chrysler sedan, routine maintenance usually has a bigger effect on confidence than headline tire specs alone.
What inflation pressure should I use for 2019 Chrysler tires?
Inflation pressure on a 2019 Chrysler 300 should follow the vehicle’s factory recommendation for the exact wheel-and-tire package, with the tire manufacturer’s maximum pressure used only as a tire rating reference, not as the everyday setting. In the available 245/45R20 products, max load figures reach 1930 pounds at 50 psi and 1929 pounds at 50 psi on specific BFGoodrich tires. Those numbers describe the tire’s rated limit, not the car’s normal operating pressure.
The correct day-to-day pressure belongs on the door placard or in the owner’s manual for your exact 17-, 18-, 19-, or 20-inch setup. Using one size’s pressure assumptions on another can change wear and ride quality. When a 2019 Chrysler 300 has aftermarket wheels or tires, compare the vehicle recommendation with the tire maker’s guidance before settling on a final pressure.
What should I check before taking a 2019 Chrysler on a longer drive?
Before a longer trip in a 2019 Chrysler 300, inspect every tire for cuts, cracking, bulges, embedded debris, uneven wear, and proper cold inflation. Check the spare as well, since an unused spare can age just like the road tires. On a car with 20-inch fitment, also make sure the wheels are free from obvious curb damage or bead-seat issues that could affect air retention.
Tires are only one part of the pre-drive picture on a modern full-size sedan, so it also makes sense to review brakes, fluids, lights, and suspension condition. A highway drive puts steady heat into the tires, and small problems become easier to notice before departure than on the shoulder of the road. A few minutes of inspection can prevent a much more disruptive problem later.
