2023 Chrysler Tire Fitment Guide

2023 Chrysler vehicles use three tire sizes, all on the Chrysler 300: 215/65R17, 235/55R19, and 245/45R20. These sizes do not interchange by default, because each one fits a different wheel diameter: 17 inches, 19 inches, or 20 inches. The 245/45R20 products in current coverage fit 20-inch wheels with a rim-width range of 7.5 to 9.0 inches where specified.

The practical takeaway is that year and make alone are not enough for a 2023 Chrysler tire search. A Chrysler 300 owner should confirm the tire placard, the existing wheel diameter, and the exact size already on the car before moving to brand or tread selection. That prevents confusion between visually similar 300 models that wear different factory wheel packages.

On a 2023 Chrysler 300, 245/45R20 breaks down into four parts: 245 is the section width in millimeters, 45 is the aspect ratio, R means radial construction, and 20 is the wheel diameter in inches. In this case, the size belongs to a 20-inch Chrysler 300 fitment rather than to every 2023 Chrysler vehicle configuration.

That code matters because each part affects compatibility. If the width, profile, or wheel diameter changes, the tire may no longer suit the wheel or the vehicle’s intended setup. Once the size is confirmed, the next comparison points are speed rating, load rating, and the wheel-width range approved for the specific tire you are considering.

No. Chrysler offered only the 300 for 2023, but the 300 itself used more than one tire size. The three sizes are 215/65R17, 235/55R19, and 245/45R20, and each one corresponds to a different wheel package rather than a universal fitment across the entire model.

That means a 2023 Chrysler 300 owner still needs to identify the exact configuration before choosing tires. Two cars that both say Chrysler 300 on the decklid can require different diameters and profiles. Checking the wheel, the sidewall on the current tire, and the placard on the car is the fastest way to avoid ordering the wrong size.

For the 2023 Chrysler 300’s covered 245/45R20 fitment, the available sidewall style is blackwall. That matches the modern performance-sedan character of the 300 and suits a late-model car far better than a period-style wide whitewall or other vintage presentation. The 17- and 19-inch fitments remain size-driven decisions first, with style choices depending on the exact tire offered in those sizes.

Sidewall appearance matters most when you want the tire to complement the look of the car rather than stand out as a restoration detail. On a modern Chrysler sedan, blackwall is the expected visual choice. After that, compare the tire’s intended character through its speed rating, load capability, and approved rim-width range instead of treating sidewall style as the main selection factor.

BFGoodrich and Nitto both have coverage for 2023 Chrysler 300 applications in the 245/45R20 size. BFGoodrich appears in several versions of the g-Force line, while Nitto covers the same size with the NT555 G2. All of those are radial blackwall tires aimed at a modern 20-inch fitment.

Brand choice comes after size confirmation. A 2023 Chrysler owner should first verify whether the car uses the 17-, 19-, or 20-inch package, then compare the brands available in that exact size. Within 245/45R20, the decision becomes more about speed rating, load capacity, and the type of driving you expect than about whether one brand is universally right for every Chrysler 300.

In 245/45R20 for the 2023 Chrysler 300, the BFGoodrich g-Force Sport COMP-2 carries a 103W rating and a stated maximum load of 1,930 pounds at 50 psi, while the Nitto NT555 G2 also carries a 103W rating. The BFGoodrich tire is shown with a 7.5- to 9.0-inch approved rim-width range, and both tires sit in roughly the 30-pound class by weight.

That means the two tires are close in broad fitment intent but still worth comparing line by line. A Chrysler 300 owner should look beyond the brand name and check the exact speed rating, load figure, and approved wheel-width range that matches the car’s wheel. When one tire publishes more complete fitment detail than another, that extra information can be useful for narrowing the choice.

Rim-width guidance is available for the 2023 Chrysler 300’s 245/45R20 fitment, where approved wheel width runs from 7.5 to 9.0 inches on the BFGoodrich options covered here. The same size also fits a 20-inch rim diameter, which is separate from wheel width. The 17- and 19-inch Chrysler 300 sizes require confirmation from the specific tire chosen in those fitments.

Wheel diameter gets most of the attention, but rim width is just as important once you have the correct size. A 2023 Chrysler owner with 20-inch wheels should verify both measurements before selecting a 245/45R20 tire. That check is especially useful if the wheels are not original or if the car has been updated with aftermarket wheels that may differ from factory width.

The covered 245/45R20 tires for the 2023 Chrysler 300 are modern radial products, and one BFGoodrich option is explicitly marked TL for tubeless use. Nothing about these fitments suggests an antique tube-type application. The 17- and 19-inch sizes belong to the same modern Chrysler 300 platform, so the starting assumption should still be to match the tire and wheel type used on the car.

The key point is to confirm the exact sidewall marking on the tire you choose and the condition of the wheel it mounts to. On a 2023 Chrysler 300, tube use would not be treated as a normal default the way it is on many vintage applications. If a wheel has been changed or repaired, inspect the valve area and bead seat carefully before mounting new tires.

A 2023 Chrysler 300 stores best on clean, properly inflated tires in a cool, dry garage away from direct sunlight, electric motors, battery chargers, furnaces, and other ozone-producing equipment. Even modern radial tires age faster when exposed to heat, UV light, and long static periods on rough concrete or damp surfaces. If the car sits for extended stretches, moving it periodically helps avoid temporary flat spotting.

Collector-style storage habits still matter even on a modern Chrysler sedan. Keep the tires clean, avoid petroleum-based dressings, and make sure the car is not resting for months on underinflated tires. If the 300 is parked long term, many owners also place a barrier under the tires or use support methods that reduce prolonged load without leaving the suspension fully hanging.

Tire life on a 2023 Chrysler 300 should be judged by age and condition, not mileage alone. A good rule is to begin close inspection around five to seven years of service and to treat roughly ten years from the DOT date code as a serious replacement point even if tread remains. Heat cycles, sun exposure, and long storage periods can shorten useful life before the tread is fully worn.

That matters because many Chrysler 300s are driven irregularly, and low annual mileage can disguise tire aging. A car that looks lightly used can still be riding on hardened rubber or developing sidewall cracking. Checking the production date on each tire and comparing that to the car’s use pattern is often more revealing than looking only at remaining tread depth.

Tires on a 2023 Chrysler 300 should be inspected before every drive and again before any longer highway trip. Look for cuts, bulges, punctures, uneven wear, sidewall cracking, and pressure loss, and do not forget the spare if the car still carries one. On a modern radial fitment, the valve stem and bead area also deserve a close look if the tire has recently been mounted or the wheel has seen curb contact.

Routine inspection catches problems long before they become roadside failures. A Chrysler 300 owner should also pay attention to changes in steering feel, vibration, or pulling, since those can point to tire damage or an inflation issue even when the tread looks acceptable at a glance. Frequent checks are simple insurance on a heavy, full-size sedan.

Yes, when the correct size is chosen and the tires are in sound condition, 2023 Chrysler 300 tires are suitable for normal highway driving. In the covered 245/45R20 fitment, available products carry W and Y speed ratings, which correspond to 168 mph and 186+ mph respectively. Those ratings are far above ordinary U.S. highway speeds and align with the modern touring and performance character of the Chrysler 300.

Real-world safety still depends on more than the speed symbol on the sidewall. Inflation, load, alignment, road hazard damage, and the vehicle’s overall mechanical condition all matter. A Chrysler 300 owner should treat the tire’s rating as one part of the picture and make sure the selected tire matches the car’s wheel size, expected use, and actual load requirements.

A 2023 Chrysler 300 should follow the factory placard or owner’s manual for everyday cold inflation pressure, because those figures are calibrated to the vehicle rather than to the tire alone. Some 245/45R20 tires in this fitment publish maximum load at 50 psi, with load figures around 1,929 to 1,930 pounds where stated, but that is not the same thing as the correct running pressure for the car.

The important distinction is that sidewall pressure information describes the tire’s rated limit under specified conditions, while Chrysler’s placard gives the target pressure for the vehicle’s balance of ride, handling, and load. A 2023 Chrysler owner should use the placard as the primary guide and reserve the tire maker’s pressure information for understanding the tire’s rating rather than setting all four tires by maximum pressure.

Before a longer trip in a 2023 Chrysler 300, inspect all four tires for cracking, cuts, bulges, punctures, and uneven wear, then confirm cold pressure against the door-jamb placard. Check the spare, the valve stems, and the inside shoulder of each tire as well, since damage can hide where it is hardest to see. If the car runs the 245/45R20 fitment, also verify that the tire still matches the wheel width it is mounted on.

A longer drive is also the right time for a broader mechanical once-over. Tire condition is only one part of making a large sedan road-ready, so braking feel, suspension behavior, and alignment should all be considered if the car has been sitting or if it recently hit potholes. A few minutes of inspection can prevent both tire trouble and avoidable handling issues on the road.
