The 2008 Chrysler 300 carried the bold, squared-shoulder styling that made this generation stand out in the modern full-size sedan market, blending American presence with rear-drive proportions and a distinctly upscale street look. That wide range of personalities matters at tire time, because the 2008 Chrysler 300 uses several different radial sizes depending on trim and drivetrain. Mainstream models center on 17-inch or 18-inch metric radials, while SRT8 fitment moves to staggered 20-inch sizing. Available tire choices also vary by brand, series, and sidewall treatment, including blackwall, redline, and raised white letter options in the 20-inch sizes. The key is matching the exact sub-model and wheel setup before comparing style or performance character.
Which Tire Size Is Right for The 2008 Chrysler 300
The 2008 Chrysler 300 uses four primary tire sizes, and the right one depends on the exact sub-model and wheel diameter. All of the primary fitments are radial, but this is not a one-size-fits-all application: some models use 17-inch wheels, some use 18-inch wheels, and SRT8 applications use 20-inch fitment, including a staggered front-and-rear setup. Confirming the sub-model and the actual wheel diameter on the car should come first.
Fit(s): C (AWD), C (RWD), C Executive Series (RWD), Limited (AWD), Limited (RWD), and Touring (AWD)
Construction: Radial|Rim: 18 in
225/60R18 is a metric radial size in which 225 identifies the nominal section width in millimeters, 60 is the aspect ratio, R denotes radial construction, and 18 is the wheel diameter in inches. On the 2008 Chrysler 300, this size serves several C, Limited, and Touring AWD or RWD applications, making it one of the core everyday fitments in the range. The emphasis here is less about appearance variation and more about confirming the correct wheel package for the specific car. It is the right place to start when the vehicle uses an 18-inch wheel and does not carry the SRT8 20-inch setup.
245/45R20 is a metric radial size with a 245-millimeter nominal section width, a 45-series profile, radial construction, and a 20-inch rim diameter. On the 2008 Chrysler 300, this size is used on SRT8 front fitment and also appears as the general SRT8 size reference, so it belongs to the performance-oriented 20-inch setup rather than the standard sedan applications. Available products in this size include BFGoodrich, Nitto, and Pro-Trac choices across blackwall, redline, and RWL sidewall styles. It is the size to evaluate when the front axle or overall SRT8 configuration calls for the narrower of the two 20-inch staggered sizes.
255/45R20 follows the same modern metric radial format, but with a wider 255-millimeter nominal section width on a 45-series profile for a 20-inch wheel. On the 2008 Chrysler 300, this size is tied to the SRT8 rear position, so it should be treated as part of a staggered arrangement rather than as a universal 20-inch fitment for every trim. BFGoodrich, Nitto, and Pro-Trac offerings are available here as well, with blackwall, redline, and RWL sidewall treatments depending on the tire series. This is the size to confirm when preserving the SRT8 rear-wheel look and maintaining the intended front-to-rear sizing relationship.
215/65R17 is a metric radial size in which 215 is the nominal section width in millimeters, 65 is the aspect ratio, R marks radial construction, and 17 designates wheel diameter. On the 2008 Chrysler 300, it is used on the LX and Touring RWD configurations, placing it with the 17-inch wheel package rather than the larger-wheel trims. This size has a more straightforward fitment role than the staggered SRT8 setup, but wheel confirmation still matters on any car that may have been changed over time. It is the correct direction when the car retains its 17-inch configuration and is not one of the 18-inch or 20-inch variants.
Tire fitment for the 2008 Chrysler 300 varies by sub-model, drivetrain, and in one case by front-versus-rear position. Checking the exact trim and wheel package matters, because the covered models span 17-inch, 18-inch, and 20-inch fitments rather than sharing one common size.

2008 Chrysler 300 C (AWD)
The 2008 Chrysler 300 C (AWD) uses an 18-inch radial fitment rather than the 17-inch base-size setup or the SRT8 20-inch arrangement. Tire selection starts with confirming that the car still wears its 18-inch wheel package, then comparing tires within that size and intended driving use.
The 2008 Chrysler 300 C (RWD) shares the same 18-inch radial size used by several non-SRT8 upper trims. That keeps fitment relatively straightforward, with the main concern being whether the car still carries the original wheel diameter or has been changed to another setup.
The 2008 Chrysler 300 C Executive Series (RWD) uses the same 18-inch radial fitment found on other C-based configurations. The practical decision is choosing the right tire within that size while confirming wheel diameter and overall setup before ordering replacements.
The 2008 Chrysler 300 C SRT8 belongs to the 20-inch performance fitment group rather than the 17-inch and 18-inch sedan sizes. Tire selection should focus first on whether the car is being matched by axle position, since SRT8 applications also appear with separate front and rear size references.
The 2008 Chrysler 300 C SRT8 Front uses the narrower of the two 20-inch SRT8 tire sizes. That makes front-position confirmation important before comparing available brands, series, or sidewall treatments in this performance-oriented fitment.
The 2008 Chrysler 300 C SRT8 Rear uses the wider 20-inch rear tire size that completes the staggered SRT8 setup. Choosing correctly here means matching the rear position specifically and avoiding the assumption that every 20-inch Chrysler 300 application uses the same size.
The 2008 Chrysler 300 LX uses the 17-inch radial size found on the simpler wheel package within the range. For this sub-model, the tire decision is mainly about staying with the correct 17-inch fitment and verifying that the car has not been upgraded to larger wheels.
The 2008 Chrysler 300 Limited (AWD) uses an 18-inch radial tire size rather than the 17-inch LX and Touring RWD fitment. That points the buyer toward the 18-inch selection path first, with wheel confirmation especially important on a vehicle that may have seen aftermarket changes.
The 2008 Chrysler 300 Limited (RWD) also uses the 18-inch radial fitment shared with several other upper-trim Chrysler 300 models. The main task is making sure the car still carries that wheel diameter so the buyer can compare the correct size rather than shopping by model name alone.
The 2008 Chrysler 300 Touring (AWD) moves to the 18-inch radial size instead of the 17-inch Touring RWD fitment. That difference makes drivetrain confirmation important, since Touring badging alone is not enough to select the correct tire.
The 2008 Chrysler 300 Touring (RWD) uses the 17-inch radial fitment rather than the 18-inch size used by Touring AWD. The practical takeaway is to confirm both drivetrain and wheel diameter before ordering, especially on a car that may now wear replacement wheels.
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 questions on the 2008 Chrysler 300 usually come down to identifying the correct sub-model, wheel diameter, and whether the car uses standard sedan fitment or the staggered SRT8 setup. The answers below focus on size, rim fitment, product choice, appearance, and practical road-use checks.
Tire Size & Fitment
What tire size fits a 2008 Chrysler 300?
The 2008 Chrysler 300 uses four primary tire sizes: 215/65R17, 225/60R18, 245/45R20, and 255/45R20. The correct one depends on the exact sub-model and wheel package, with LX and Touring RWD using 17-inch fitment, several C and Limited models using 18-inch fitment, and SRT8 applications using 20-inch sizing.
The first step is matching the tire to the actual car, not just the model name on the decklid. Touring AWD and Touring RWD do not use the same size, and SRT8 fitment can involve separate front and rear sizes, so confirming trim, drivetrain, axle position, and wheel diameter prevents ordering the wrong tire.
What size rim does a 2008 Chrysler 300 use?
A 2008 Chrysler 300 can use 17-inch, 18-inch, or 20-inch rims depending on sub-model. The 215/65R17 fitment uses a 17-inch rim, the 225/60R18 fitment uses an 18-inch rim, and the 245/45R20 and 255/45R20 SRT8 sizes use 20-inch rims.
Wheel diameter should be confirmed before choosing a tire, especially on a used Chrysler 300 that may have received aftermarket wheels. Tire size, rim diameter, and trim level need to agree with each other, and on SRT8 models the front and rear wheel-and-tire pairing should be checked as a matched setup rather than assumed from one corner.
Why does the 2008 Chrysler 300 have more than one tire size?
The 2008 Chrysler 300 has more than one tire size because the model range covers several trims, drivetrains, and wheel packages. Standard sedan versions use either 17-inch or 18-inch radial fitment, while the SRT8 moves to 20-inch performance-oriented sizing, including a staggered arrangement with different front and rear tire sizes.
That variation means tire selection is tied to configuration, not just year and model badge. A buyer should confirm whether the car is LX, Touring, Limited, C, or SRT8, and whether it is AWD or RWD where that changes fitment, then verify the actual wheels on the vehicle before comparing tire choices.
Choosing the Right Tire
What should I consider when choosing a 245/45R20 or 255/45R20 tire for a 2008 Chrysler 300?
For a 2008 Chrysler 300 using 245/45R20 or 255/45R20, the main considerations are axle position, correct size, radial construction, and the tire's intended character. These sizes belong to SRT8 fitment, and available choices vary by brand, tire series, sidewall style, rim-width specification, and in some cases stated load figures.
A useful approach is to decide whether the priority is a clean blackwall performance look or a more distinctive redline or raised white letter presentation. Front and rear sizes should not be treated as interchangeable, and the wheel width on the car should be checked against the tire's fitment range before making a final selection.
What sidewall styles are available for 2008 Chrysler 300 tires?
The visible sidewall choices shown for the 2008 Chrysler 300 are blackwall, redline, and RWL on the 20-inch SRT8 sizes. Blackwall appears across BFGoodrich and Nitto offerings, while Pro-Trac Street Pro III options add redline and raised white letter styling in both 245/45R20 and 255/45R20.
Sidewall style does not change the need to match the correct size and wheel, but it can change the car's presentation noticeably. A blackwall keeps the look understated and modern, while redline or RWL adds more visual emphasis, so the best choice depends on whether the goal is a cleaner performance sedan look or something more expressive.
What brands offer tires for the 2008 Chrysler 300?
For the 20-inch Chrysler 300 applications, available brands include BFGoodrich, Nitto, and Pro-Trac. Those options cover several radial product lines, including g-Force variants, Nitto NT555 G2, and Pro-Trac Street Pro III, giving SRT8 buyers a mix of brand identity and style choices within the correct sizes.
Brand should be compared alongside the actual tire series, sidewall presentation, and wheel specifications rather than treated as the only decision point. A Chrysler 300 owner should first confirm whether the car uses the 245/45R20 front size or the 255/45R20 rear size, then compare the available products within that exact fitment.
Restoration & Appearance
Which tire should I choose for a period-style 2008 Chrysler 300?
A period-style 2008 Chrysler 300 tire choice starts with the exact original-size format for the sub-model, since this is a modern radial-fitment car rather than a vintage bias-ply application. For SRT8 sizes, blackwall, redline, and RWL options create different visual impressions while still staying within the correct 20-inch size family.
The best appearance choice depends on how the car is being presented today. A cleaner, more restrained look usually points toward blackwall, while redline or raised white letter styling gives the Chrysler 300 a stronger custom or muscle-influenced visual character, especially on the larger 20-inch wheel package.
Does correct tire fitment matter for a 2008 Chrysler 300 restoration?
Correct tire fitment matters on a 2008 Chrysler 300 restoration because wheel diameter and tire size are part of the car's stance, proportions, and intended trim-level presentation. A 17-inch Touring or LX setup, an 18-inch C or Limited setup, and a 20-inch SRT8 setup do not create the same visual result.
Using the right size family also avoids blending appearance goals with fitment mistakes. Even when a Chrysler 300 is being refreshed more as a collector-driven modern classic than a strict restoration, matching the tire to the proper trim and wheel package helps preserve the car's character and keeps later clearance questions to a minimum.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2008 Chrysler 300?
Yes, modifications can affect tire fitment on a 2008 Chrysler 300. Aftermarket wheels, suspension changes, lowering, spacer use, or body modifications can alter the relationship between the tire, wheel opening, and steering components, even when the tire size itself matches one of the standard Chrysler 300 fitments.
That is especially important on SRT8 applications, where the 20-inch setup already uses distinct sizing by position. Any modified Chrysler 300 should have wheel diameter, wheel width, tire-to-fender clearance, and steering clearance checked on the actual car before new tires are chosen simply by trim label or stock specification.
What should I inspect before driving a 2008 Chrysler 300 on new tires?
Before driving a 2008 Chrysler 300 on new tires, inspect the wheels for damage, confirm the tire sizes match the correct sub-model, and make sure inflation is set properly for the application. It is also smart to look over suspension and steering components so the new tires are not being asked to compensate for worn hardware.
A short first drive should be used to check for rubbing, vibration, or any sign that the car's current wheel-and-tire setup differs from what was expected. On an SRT8, verify that the front and rear tires are mounted in their proper positions so the staggered arrangement remains consistent across the car.
What should I check before a longer drive in a 2008 Chrysler 300?
Before a longer drive in a 2008 Chrysler 300, check tire pressure, inspect tread and sidewalls for cuts or bulges, and confirm there is no unusual air loss. It is also worth looking for uneven wear that could suggest an alignment or suspension issue, particularly on cars with larger wheels or performance-oriented fitment.
Longer-distance confidence comes from knowing the full setup is stable, not just the rubber itself. A Chrysler 300 that has sat for extended periods, has aftermarket wheels, or uses the staggered SRT8 tire combination deserves an extra look at wheel fasteners, visible clearances, and overall tire condition before heading out.
