The 2009 Chrysler 300 carried the model’s distinctive full-size sedan presence into the late-2000s, blending American-style proportions with trims that ranged from everyday touring duty to more aggressive performance versions. That wide spread in character is reflected in the tire fitment. Depending on sub-model, the 2009 Chrysler 300 uses 215/65R17, 225/60R18, 245/45R20, or 255/45R20 radial tires. The 20-inch fitments bring additional choice through blackwall, redline, and raised white letter sidewall styles, along with several sport-oriented tire series. The key is matching the tire to the exact trim and wheel setup before comparing appearance, handling character, or replacement options.
Which Tire Size Is Right for The 2009 Chrysler 300
The 2009 Chrysler 300 uses four primary tire sizes, and the right one depends on the exact sub-model and wheel diameter. All of these are metric radial sizes, but they span 17-inch, 18-inch, and 20-inch rims, with the SRT8 setup also using different front and rear sizes. The first step is confirming the exact trim and wheel size already on the car before choosing a replacement tire.
Fit(s): C (AWD), C (RWD), C Executive Series (RWD), Limited (AWD), Limited (RWD), Touring (AWD), and Touring Executive Series (RWD)
Construction: Radial|Rim: 18 in
A 225/60R18 tire uses a 225-millimeter nominal section width, a 60-series aspect ratio, radial construction, and fits an 18-inch rim. On the 2009 Chrysler 300, this size serves several C, Limited, and Touring variants, making it an important fitment for buyers with mid-level wheel packages. Its role is less about appearance variety and more about confirming the correct trim and wheel combination first. This size is the right place to focus when the car is equipped with 18-inch factory-style wheels and you want to stay aligned with the original fitment format.
Fit(s): C Heritage (RWD), C SRT8, and C SRT8 Front
Construction: Radial|Rim: 20 in
A 245/45R20 tire is a metric radial with a 245-millimeter nominal width, a 45-series profile, and a 20-inch rim diameter. On the 2009 Chrysler 300, it appears on 20-inch performance-oriented applications, including the C Heritage and the front of the C SRT8 setup. Available choices include BFGoodrich, Nitto, and Pro-Trac, with blackwall, redline, and RWL sidewall treatments across several tire series. This size deserves close attention if your car wears 20-inch wheels and you want to balance correct fitment with a particular visual style.
A 255/45R20 tire keeps the same 20-inch rim diameter as the 245/45R20 but increases nominal width to 255 millimeters while retaining radial construction and a 45-series profile. On the 2009 Chrysler 300, this size is used at the rear of the C SRT8, so it plays a specific role within a staggered front-to-rear setup rather than across the full model line. BFGoodrich, Nitto, and Pro-Trac options are available, including blackwall, redline, and RWL styles. It should be evaluated as a rear-axle fitment only after confirming the wheel width and overall SRT8 configuration.
A 215/65R17 tire has a 215-millimeter nominal section width, a 65-series aspect ratio, radial construction, and fits a 17-inch rim. On the 2009 Chrysler 300, this size is associated with LX, Signature Series, and some Touring applications, placing it among the more straightforward non-20-inch fitments in the range. The practical decision here is confirming that the car is actually on the 17-inch wheel package rather than an 18-inch or 20-inch setup. That matters especially on used vehicles, where wheel changes can blur the line between trims and original tire sizes.
Tire fitment on the 2009 Chrysler 300 varies meaningfully by sub-model, so trim identification matters before any tire is selected. The main distinction is wheel diameter, with some versions on 17-inch or 18-inch setups and certain 20-inch performance models using a more specialized fitment.

2009 Chrysler 300 C (AWD)
The 2009 Chrysler 300 C (AWD) uses the 225/60R18 radial size. That makes the buying decision less about multiple fitments and more about confirming the 18-inch wheel setup before comparing replacement tire character and intended road use.
The 2009 Chrysler 300 C (RWD) also uses 225/60R18 radial tires. Buyers with this trim should verify that the car still carries the correct 18-inch wheels, especially if it has seen aftermarket changes over time.
The 2009 Chrysler 300 C Executive Series (RWD) is fitted with the same 225/60R18 radial size. Tire selection starts with that 18-inch fitment and then moves to replacement priorities such as everyday use, ride character, and wheel compatibility.
The 2009 Chrysler 300 C Heritage (RWD) uses a 245/45R20 radial tire. This places it with the 20-inch fitments, where buyers can compare available sidewall styles and tire series after confirming the wheel package.
The 2009 Chrysler 300 C SRT8 uses a 245/45R20 radial tire in the core fitment record, but the dedicated front and rear entries show a staggered 20-inch setup. Selection should start by confirming whether the car still uses its intended front and rear wheel arrangement.
The front fitment for the 2009 Chrysler 300 C SRT8 is 245/45R20. That front-specific role matters because tire choice should preserve the intended staggered arrangement rather than treating all four corners as identical.
The rear fitment for the 2009 Chrysler 300 C SRT8 is 255/45R20. Buyers should treat this as a dedicated rear size and confirm wheel width and axle position before selecting among the available 20-inch replacements.
The 2009 Chrysler 300 LX uses the 215/65R17 radial size. Tire selection is most straightforward here, with the main task being confirmation that the car remains on the proper 17-inch wheel package.
The 2009 Chrysler 300 Limited (AWD) uses 225/60R18 radial tires. That keeps it in the 18-inch group, where correct wheel diameter comes first before comparing any replacement tire options.
The 2009 Chrysler 300 Limited (RWD) also uses the 225/60R18 radial size. A buyer should confirm that the wheels match that fitment, since wheel swaps on used 300s can easily change what size is actually needed today.
The 2009 Chrysler 300 Signature Series uses 215/65R17 radial tires. That makes it part of the 17-inch fitment group, where the focus is on staying with the correct diameter and overall trim-specific setup.
The 2009 Chrysler 300 Touring (AWD) uses the 225/60R18 radial size. Buyers should verify the 18-inch wheel setup first, then move on to selecting a tire that suits the car’s actual driving use and condition.
The 2009 Chrysler 300 Touring (RWD) uses 215/65R17 radial tires. That distinction is important because Touring models do not all share the same fitment, so trim and wheel confirmation should happen before ordering replacements.
The 2009 Chrysler 300 Touring Executive Series (RWD) uses the 225/60R18 radial size. It belongs with the 18-inch fitments, so correct replacement starts with wheel confirmation rather than assuming all Touring versions use the same tire.
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 2009 Chrysler 300?
The 2009 Chrysler 300 uses four primary tire sizes: 215/65R17, 225/60R18, 245/45R20, and 255/45R20. The correct size depends on the exact sub-model and wheel package, with most trims using a single size and the C SRT8 range introducing 20-inch fitments, including a dedicated rear 255/45R20 entry.
That means the first job is identifying the exact trim and checking the wheel diameter currently on the car. A used 300 may no longer wear its original wheels, so reading the sidewall and confirming the wheel setup matters more than assuming every 2009 Chrysler 300 uses the same tire.
What size rim does a 2009 Chrysler 300 use?
A 2009 Chrysler 300 can use 17-inch, 18-inch, or 20-inch rims, depending on the sub-model. The 215/65R17 fitments use 17-inch rims, the 225/60R18 fitments use 18-inch rims, and the 245/45R20 and 255/45R20 fitments use 20-inch rims.
Rim diameter is the most important fitment checkpoint because the tire must match it exactly. Wheel width also matters, especially on the 20-inch sizes, so buyers should confirm both the wheel diameter and the actual wheel setup already on the vehicle before choosing among available replacement tires.
Why does the 2009 Chrysler 300 have more than one tire size?
The 2009 Chrysler 300 spans several sub-models with different wheel packages, which is why more than one tire size applies. LX, Signature Series, Touring, C, Limited, Heritage, and SRT8 variations do not all share the same wheel diameter, and the C SRT8 rear fitment differs from its front fitment.
That variation means trim level and wheel configuration are tied directly to tire choice. It is best to confirm the exact sub-model name, read the current tire size, and check whether the car uses a square setup or a staggered front-and-rear arrangement before settling on a replacement.
Choosing the Right Tire
What should I consider when choosing a tire for a 2009 Chrysler 300?
Start with the correct size for the exact 2009 Chrysler 300 sub-model, then confirm the wheel diameter and whether the car uses a uniform or staggered setup. Since all primary fitments here are radial, the main decision usually becomes selecting the right tire within that size rather than changing construction type.
Once the size is confirmed, compare the available tire series, sidewall treatments, and wheel-width compatibility where applicable. A 20-inch Heritage or SRT8 application calls for a different selection approach than a 17-inch or 18-inch trim, especially if appearance and wheel specifications both matter to the final choice.
What sidewall styles are available for 2009 Chrysler 300 tires?
Among the available 20-inch Chrysler 300 tire options, sidewall styles include Blackwall, Redline, and RWL. Blackwall appears across several BFGoodrich and Nitto choices, while Pro-Trac Street Pro III adds Redline and RWL alternatives in both 245/45R20 and 255/45R20 sizes.
That sidewall variation matters most for buyers trying to shape the car’s overall presentation. A blackwall keeps a more understated look, while redline or raised white letter styling adds a stronger visual statement, so the final choice should reflect both the correct fitment and the appearance you want from the car.
What brands offer tires for the 2009 Chrysler 300?
Available 20-inch tires for the 2009 Chrysler 300 come from BFGoodrich, Nitto, and Pro-Trac. Those brands cover the 245/45R20 and 255/45R20 sizes with multiple radial tire series, including sport-focused blackwall options as well as redline and raised white letter alternatives.
Brand choice should come after confirming the exact tire size and wheel setup on the car. Once fitment is settled, compare each brand’s available series, sidewall style, wheel-width specifications where shown, and overall visual character instead of treating every 20-inch tire as the same kind of replacement.
Restoration & Appearance
Which tire should I choose for a period-style 2009 Chrysler 300?
A period-style 2009 Chrysler 300 build should begin with the correct trim-specific tire size and wheel diameter, since that establishes the car’s stance before anything else. For 20-inch applications, the available choices include blackwall, redline, and RWL sidewall treatments, which can change the look of the car substantially.
A cleaner factory-inspired presentation usually points buyers toward a blackwall, while redline or raised white letter tires can create a more customized, muscle-influenced look. When exact historical originality matters, it is wise to compare the car against window-sticker information, original photos, or model-specific Chrysler enthusiast references.
Does correct tire fitment matter for a 2009 Chrysler 300 restoration?
Correct tire fitment matters because the 2009 Chrysler 300 was offered with more than one wheel and tire combination. Using the proper 17-inch, 18-inch, or 20-inch size helps preserve the intended proportions of the specific trim, and the SRT8 rear fitment adds another detail that affects the finished look.
Appearance is only part of the picture. Correct size selection also supports proper wheel matching and helps avoid an obviously mismatched stance, so a restoration-minded buyer should verify the trim, current wheels, and front-to-rear setup before choosing a tire mainly on sidewall style alone.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2009 Chrysler 300?
Yes. Modifications such as aftermarket wheels, suspension changes, altered ride height, or bodywork can affect tire fitment on a 2009 Chrysler 300 even when the tire size seems close to stock. That is especially important on 20-inch applications and on the staggered C SRT8 setup, where front and rear roles differ.
A modified car should be checked for wheel diameter, wheel width, steering clearance, and fender clearance before replacement tires are chosen. Even a correct-looking size can create problems if the wheel specification or suspension position has changed from the configuration that originally used that tire.
What should I inspect before driving a 2009 Chrysler 300 on new tires?
Before driving, inspect the wheels for damage, confirm that the tire size matches the sub-model and axle position, and make sure the tires are seated and inflated properly. It is also smart to check for suspension wear, alignment issues, and any signs that the old tires were rubbing or wearing unevenly.
A short road test should include attention to steering feel, vibration, and clearance during turning and compression. On a 2009 Chrysler 300 with 20-inch tires, especially an SRT8 arrangement, confirm that the front and rear sizes are installed in their proper positions before putting regular miles on the car.
How often should tires on a 2009 Chrysler 300 be inspected?
Tires on a 2009 Chrysler 300 should be inspected regularly for air loss, uneven tread wear, cracking, cuts, and bulges. A monthly visual inspection is a practical baseline, and any car that sits for long periods deserves extra attention because low-use vehicles can hide age-related issues behind low mileage.
Inspection matters even more before highway driving or seasonal use. A Chrysler 300 that has been stored, driven infrequently, or fitted with larger 20-inch tires should have its pressures checked and its tread and sidewalls reviewed carefully so small problems are caught before they become road-use problems.
