The 2010 Chrysler 300 blends full-size American sedan presence with a more assertive, modern performance character than many buyers expect, especially in upper trims and SRT8 form. By this point in the 300’s run, wheel and tire fitment could vary quite a bit depending on drivetrain and sub-model, so the first step is identifying the exact configuration on the car. This model year uses radial tires throughout, with primary sizes ranging from 215/65R17 and 225/60R18 to 245/45R20 and 255/45R20. That opens the door to different visual and driving personalities, including blackwall, redline, and raised white letter options in the 20-inch sizes. The right choice depends on whether the goal is stock-style fitment, a sportier look, or maintaining the existing wheel setup.
Which Tire Size Is Right for The 2010 Chrysler 300
The 2010 Chrysler 300 uses four primary tire sizes, and the correct one depends on the exact sub-model and wheel diameter. All of them are radial sizes, but they span 17-inch, 18-inch, and 20-inch rims, so confirming the specific trim and the actual wheels on the car comes first. Once that is settled, the real choice becomes tread and sidewall style, brand selection, and whether the car is being kept close to stock or tailored to a more performance-oriented look.
Fit(s): C (AWD), C (RWD), C Executive Series (RWD), Limited (AWD), Limited (RWD), Touring Executive Series (RWD), Touring Signature (AWD), and Touring Signature (RWD)
Construction: Radial|Rim: 18 in
225/60R18 is a modern metric radial size in which 225 identifies the nominal section width in millimeters, 60 is the aspect ratio, and 18 is the rim diameter in inches. On the 2010 Chrysler 300, this size suits several AWD and RWD sub-models and represents a balanced full-size sedan fitment rather than an overtly aggressive one. It sits in the middle of this model year’s tire range, so wheel confirmation is still important if the car has been changed from its original setup. This is the size to use when your specific 300 configuration calls for an 18-inch radial and the goal is to preserve the intended stance and proportions.

Construction: Radial|Rim: 20 in
245/45R20 is a metric radial size with a 245-millimeter nominal width, a 45-series profile, and a 20-inch rim diameter. On the 2010 Chrysler 300, it appears on several sportier-looking sub-models and also serves as the front fitment on the 300 C SRT8, so it should not be assumed to apply across the whole model line. Product choice in this size is broader, with BFGoodrich, Nitto, and Pro-Trac offerings plus blackwall, redline, and raised white letter sidewall treatments. This is the size to evaluate carefully when the car already wears 20-inch wheels and appearance plays a big part in the decision.
255/45R20 is a metric radial size where 255 is the nominal section width in millimeters, 45 is the aspect ratio, and 20 is the rim diameter in inches. For the 2010 Chrysler 300, this size is tied to the rear position on the 300 C SRT8, which makes it a more specialized fitment than the other sizes on this page. Available choices include BFGoodrich, Nitto, and Pro-Trac products in blackwall, redline, and raised white letter form. This size deserves close attention because rear fitment, wheel width, and overall setup matter more on a staggered application than on a standard four-corner arrangement.
215/65R17 is a metric radial size made up of a 215-millimeter nominal section width, a 65-series profile, and a 17-inch rim diameter. On the 2010 Chrysler 300, this size is associated with the Touring (RWD) configuration and reflects a taller-profile, comfort-oriented fitment compared with the 20-inch applications. It fills a different role from the lower-profile sport sizes, so a buyer should not substitute it casually just because the overall tire diameter is in a similar range. This is the size to use when the car retains its 17-inch wheel setup and the sub-model calls for that original fitment direction.
Tire fitment on the 2010 Chrysler 300 varies by sub-model, and the differences are significant enough that trim identification matters before choosing a tire. Some versions use 17-inch or 18-inch wheel packages, while others move to 20-inch fitments, including a staggered front and rear setup on the SRT8.

2010 Chrysler 300 C (AWD)
The 2010 Chrysler 300 C (AWD) uses a 225/60R18 radial tire. That keeps selection focused on confirming the 18-inch wheel setup and choosing the right replacement style for everyday road use rather than sorting through multiple primary fitments.
The 2010 Chrysler 300 C (RWD) also uses 225/60R18 radial tires. Tire choice here centers on maintaining the proper 18-inch fitment and checking whether the car still wears its original wheel package or has been changed to another diameter.
The 2010 Chrysler 300 C Executive Series (RWD) uses the same 225/60R18 radial size. That makes the main decision less about finding the fitment and more about confirming wheel condition and selecting a tire that suits the sedan’s intended look and road use.
The 2010 Chrysler 300 C Heritage (RWD) uses a 245/45R20 radial tire. With a 20-inch fitment, attention shifts toward matching the existing wheel package and deciding between more understated blackwall styling or more distinctive sidewall treatments where available.
The 2010 Chrysler 300 C SRT8 uses 20-inch radial fitment, and this model line also appears with separate front and rear size assignments.

Questions around the 2010 Chrysler 300 usually come down to identifying the right sub-model, confirming 17-, 18-, or 20-inch wheel fitment, and choosing among available radial tire styles. The FAQs below also cover staggered SRT8 sizing, sidewall options, and key checks before road use.
Tire Size & Fitment
What tire size fits a 2010 Chrysler 300?
A 2010 Chrysler 300 can use 215/65R17, 225/60R18, 245/45R20, or 255/45R20, depending on the exact sub-model and wheel position. All of these are radial tire sizes, but they are not interchangeable primary fitments across the entire model range.
The key is matching the tire size to the exact trim and the wheels currently on the car. Touring (RWD) uses 215/65R17, many C, Limited, and Touring Signature variations use 225/60R18, several sport-oriented trims use 245/45R20, and the 300 C SRT8 rear uses 255/45R20.
What size rim does a 2010 Chrysler 300 use?
The 2010 Chrysler 300 appears with 17-inch, 18-inch, and 20-inch rim diameters, depending on sub-model. That means rim size is one of the first things to confirm before selecting tires, especially if the car has changed hands or has aftermarket wheels.
A Touring (RWD) uses a 17-inch setup with 215/65R17, several AWD and RWD trims use 18-inch wheels with 225/60R18, and multiple higher-style or performance-oriented versions use 20-inch tires. On the SRT8, 20-inch wheels also come with different front and rear tire sizes, so wheel position matters too.
Why does the 2010 Chrysler 300 have more than one tire size?
The 2010 Chrysler 300 has more than one tire size because fitment changes across sub-models, drivetrains, and wheel packages. Some versions use a more comfort-oriented 17-inch or 18-inch setup, while others move to lower-profile 20-inch tires for a different stance and appearance.
That variation means the right tire is tied to the specific version of the car rather than the 300 name alone. It is smart to confirm the trim badge, check the current tire sidewall, and verify the actual wheel diameter before choosing a replacement, particularly on cars with previous wheel or suspension changes.
Choosing the Right Tire
What should I consider when choosing a tire for a 2010 Chrysler 300?
Start with the correct tire size for the exact 2010 Chrysler 300 sub-model and wheel diameter. After that, the main considerations are whether the car uses a standard or staggered setup, the available tire series in that size, sidewall appearance, and any relevant rim-width or load specifications shown on the tire options.
A Touring on 17-inch wheels calls for a different approach than a 20-inch SRT8 or Heritage model. It also helps to think about how the car is used: regular cruising, performance-minded driving, or a more appearance-focused build can each point toward a different radial tire within the correct size.
What sidewall styles are available for 2010 Chrysler 300 tires?
The visible sidewall variety in this fitment centers on the 20-inch sizes. In 245/45R20 and 255/45R20, available styles include blackwall, redline, and RWL, which can be described naturally as raised white letter.
That gives a 2010 Chrysler 300 owner a meaningful appearance choice without changing the primary tire size. Blackwall keeps the look understated, while redline and raised white letter options create a more custom or performance-flavored presentation. The best approach is to choose the sidewall style after the correct size and wheel setup have already been confirmed.
What brands offer tires for the 2010 Chrysler 300?
In the 20-inch fitments for the 2010 Chrysler 300, available brands include BFGoodrich, Nitto, and Pro-Trac. Those choices appear in 245/45R20 and 255/45R20, giving buyers multiple ways to compare tire character and appearance within the correct size.
Brand alone should not be the only deciding factor. It is more useful to compare the exact tire series, sidewall treatment, rim-width suitability where stated, and the intended role of the car. A staggered SRT8 setup also needs extra attention so the selected front and rear tires remain properly matched to their wheel positions.
How do I choose between the available 20-inch tires for a 2010 Chrysler 300?
The 20-inch choices for a 2010 Chrysler 300 are best sorted by exact size first, then by brand, tire series, and sidewall style. A 245/45R20 front or four-corner fitment should not be confused with the 255/45R20 rear size used on the 300 C SRT8.
Once the size is confirmed, compare what matters to the car’s purpose. Some tires are offered only as blackwalls, while others also come in redline or raised white letter form. Rim-width guidance is also worth checking, especially on cars with aftermarket wheels or on SRT8 applications where front and rear fitment differ.
Restoration & Appearance
Which tire should I choose for a period-style 2010 Chrysler 300?
A period-style 2010 Chrysler 300 starts with using the exact tire size assigned to the car’s sub-model and wheel package. Because this is a modern-era sedan with radial fitments throughout, the visual decision usually comes down to keeping a clean blackwall look or choosing a more expressive sidewall treatment in the available 20-inch sizes.
The most convincing appearance usually comes from matching the tire to the car’s trim level and stance rather than forcing a style from another application. On 20-inch cars, redline or raised white letter tires can change the presentation noticeably, while 17-inch and 18-inch owners may place more emphasis on maintaining stock-style proportions.
How does tire construction affect the appearance of a restored 2010 Chrysler 300?
On a 2010 Chrysler 300, construction does not create a bias-ply-versus-radial decision because the primary fitments are radial. The visual difference comes more from size, profile, and sidewall treatment than from construction type itself.
That means a restoration-oriented owner should focus on preserving the proper wheel diameter and the tire’s overall visual proportion on the car. A 17-inch Touring setup presents differently from a 20-inch Heritage, S, or SRT8 setup, and sidewall details such as blackwall, redline, or raised white letter can further shape the finished look.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2010 Chrysler 300?
Yes, modifications can affect tire fitment on a 2010 Chrysler 300, especially because this model already spans 17-inch, 18-inch, and 20-inch wheel packages. Aftermarket wheels, suspension changes, altered ride height, or wheel spacers can all change the clearances that the original tire sizes were designed around.
That is particularly important on 20-inch cars and on the staggered 300 C SRT8 layout, where wheel position matters. A tire that matches the nominal size still needs to be checked against actual wheel width, steering travel, fender room, and suspension condition before assuming the existing modified setup will accept it cleanly.
What should I inspect before driving a 2010 Chrysler 300 on new tires?
Before driving a 2010 Chrysler 300 on new tires, inspect the wheels for damage, confirm the tire size matches the exact sub-model, and make sure the tires are mounted in the correct positions. On SRT8 applications, that includes verifying that 245/45R20 fronts and 255/45R20 rears have not been mixed.
It also helps to check inflation, valve stems, tread seating, and visible clearance at the fenders and suspension. A short, careful road test can reveal rubbing, pull, vibration, or interference that was not obvious on the lift. Any car with aftermarket wheels should get extra attention before regular road use.
How often should tires on a 2010 Chrysler 300 be inspected?
Tires on a 2010 Chrysler 300 should be inspected regularly, not just when they look low or begin to wear unevenly. A quick visual check for cracking, cuts, bulges, irregular tread wear, and air loss is worthwhile before longer drives and as part of routine maintenance.
Cars that see limited use still need attention because age and storage conditions matter even when mileage stays low. It is also smart to watch for signs of alignment or suspension issues, especially on 20-inch fitments and staggered setups, where uneven wear can develop quickly if the car is out of specification.
