The 2007 Chrysler 300 blends full-size American sedan presence with a distinctly modern performance-touring character, ranging from everyday Base and Touring trims to the more aggressive C and SRT8 configurations. That wide spread of personalities carries directly into tire fitment. This model year uses four primary radial sizes: 215/65R17, 225/60R18, 245/45R20, and 255/45R20, with size selection tied to the exact sub-model and wheel package. The strongest product depth appears in the 20-inch SRT8 sizes, where blackwall, redline, and raised white letter choices add a noticeable visual difference. For a 2007 Chrysler 300, the right decision starts with the exact trim, then moves to wheel diameter, tire style, and intended road use.
Which Tire Size Is Right for The 2007 Chrysler 300
The 2007 Chrysler 300 uses four primary tire sizes, and the correct one depends on the exact sub-model and wheel diameter. Fitment spans 17-inch, 18-inch, and 20-inch rims, so the first step is confirming whether the car is a Base, Touring, C, Limited, or SRT8 configuration and then matching the tire to the wheel already on the vehicle.
Fit(s): Base, Touring (RWD), and Touring Executive Series (RWD)
Construction: Radial|Rim: 17 in
215/65R17 is a metric radial size in which 215 identifies the section width in millimeters, 65 is the aspect ratio, R indicates radial construction, and 17 is the rim diameter in inches. On the 2007 Chrysler 300, this size serves 17-inch wheel applications rather than the larger-wheel trims. Its taller-profile look suits buyers who want to stay with the original wheel diameter and maintain the intended stance of the covered Base and Touring applications. The key reason to choose this size is preserving the correct fitment for the 17-inch setup already on the car.
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, with a 225-millimeter section width, a 60-series profile, and an 18-inch rim diameter. This is the primary fitment for several 2007 Chrysler 300 C, Limited, and Touring configurations, making it the central choice for many non-SRT8 cars equipped with 18-inch wheels. It balances a substantial sidewall with a larger wheel diameter than the 17-inch fitment, so selection is less about construction changes and more about confirming the exact trim and wheel package. Buyers should use this size only after verifying that the car is on the 18-inch setup.
245/45R20 is a metric radial size that uses a 245-millimeter section width, a 45-series profile, and a 20-inch rim diameter. On the 2007 Chrysler 300, it is associated with the front fitment used on SRT8 applications rather than the regular sedan trims. Product choice is broader here, with BFGoodrich, Nitto, and Pro-Trac offerings plus blackwall, redline, and RWL sidewall treatments across several series. This is the size to evaluate when the car carries the SRT8 front-wheel setup and the owner wants to compare both performance-oriented and appearance-oriented tire choices.
255/45R20 is a metric radial size, where 255 is the section width in millimeters, 45 is the aspect ratio, and 20 identifies the wheel diameter. On the 2007 Chrysler 300, this size is tied to the rear position on SRT8 fitment, giving that application a wider rear tire than the front. Available choices include BFGoodrich, Nitto, and Pro-Trac options, with blackwall, redline, and RWL presentations depending on the tire series. This size matters when keeping the staggered 20-inch SRT8 setup intact and confirming that the rear wheel width matches the tire's intended range.
Tire fitment on the 2007 Chrysler 300 changes by sub-model, and the wheel diameter changes with it. Checking the exact trim matters because this model year ranges from 17-inch fitments to 18-inch and staggered 20-inch SRT8 applications.

2007 Chrysler 300 Base
The 2007 Chrysler 300 Base uses the 215/65R17 radial size on a 17-inch wheel setup. Tire selection here centers on staying with the correct 17-inch fitment rather than stepping into the larger-wheel sizes used by other 300 trims.
The 2007 Chrysler 300 C (AWD) uses 225/60R18 radial tires. That makes wheel confirmation especially important, since this trim shares its size with several other 18-inch Chrysler 300 configurations but not with the 17-inch or SRT8 20-inch setups.
The 2007 Chrysler 300 C (RWD) also uses the 225/60R18 radial size. The main selection task is matching the existing 18-inch wheel package and then choosing a tire that suits the car's intended road use and overall presentation.
The 2007 Chrysler 300 C Executive Series (RWD) uses 225/60R18 radial tires. Buyers with this trim should focus first on preserving the 18-inch fitment, then comparing tire choices that maintain the right proportions for the car's wheel and suspension setup.
The 2007 Chrysler 300 C SRT8 uses 245/45R20 at the front and 255/45R20 at the rear as part of its 20-inch performance-oriented setup. Tire selection here depends on keeping the staggered arrangement straight and choosing the sidewall style and series that fit the car's intended look.
The front position of the 2007 Chrysler 300 C SRT8 uses 245/45R20 radial tires. This is where buyers can compare blackwall, redline, and RWL choices while still confirming that the front wheel width matches the tire's intended application.
The rear position of the 2007 Chrysler 300 C SRT8 uses the wider 255/45R20 radial size. Keeping that rear fitment distinct from the front matters, especially on cars where wheels or suspension settings may have been altered over time.
The 2007 Chrysler 300 Limited (AWD) uses 225/60R18 radial tires. For this trim, the decision is mostly about confirming the 18-inch wheel package and selecting a tire that keeps the intended fitment without crossing into SRT8-specific 20-inch sizes.
The 2007 Chrysler 300 Limited (RWD) shares the 225/60R18 radial fitment. That makes selection fairly straightforward once the wheel diameter is confirmed, with the focus then shifting to the kind of driving the car sees and the appearance the owner wants.
The 2007 Chrysler 300 Touring (AWD) uses 225/60R18 radial tires. It is important not to assume all Touring models use the same size, since Touring fitment changes within the model range and depends on the exact drivetrain and wheel combination.
The 2007 Chrysler 300 Touring (RWD) uses 215/65R17 radial tires rather than the 18-inch size found on some other Touring-related configurations. The practical step is confirming that the car still carries its 17-inch wheels before selecting replacement tires.
The 2007 Chrysler 300 Touring Executive Series (RWD) uses the 215/65R17 radial size. Buyers should treat it as a 17-inch fitment first, then evaluate tire choice around maintaining proper dimensions and overall compatibility with the existing wheel setup.
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.

Product choice is concentrated in the 20-inch SRT8 sizes, where BFGoodrich, Nitto, and Pro-Trac options span several radial series and sidewall treatments. Blackwall, redline, and RWL tires give buyers a meaningful appearance decision alongside rim-width and load-capacity details.
For the 2007 Chrysler 300, the most common questions center on identifying the right trim-specific tire size, understanding the staggered SRT8 setup, and comparing sidewall, brand, and wheel-fitment details before putting the car back on the road.
Tire Size & Fitment
What tire size fits a 2007 Chrysler 300?
The 2007 Chrysler 300 uses four primary tire sizes depending on sub-model: 215/65R17, 225/60R18, 245/45R20, and 255/45R20. Base and some Touring applications use 215/65R17, several C and Limited models use 225/60R18, and the SRT8 uses a 20-inch staggered setup with 245/45R20 in front and 255/45R20 in the rear.
The practical step is matching the tire size to the exact trim and the wheels currently on the car. A Chrysler 300 that has been fitted with aftermarket wheels or changed suspension parts should be checked carefully, because the model year spans three wheel diameters and one performance application uses different front and rear sizes.
What size rim does a 2007 Chrysler 300 use?
A 2007 Chrysler 300 can use 17-inch, 18-inch, or 20-inch rims depending on the sub-model. The 215/65R17 fitment belongs to 17-inch wheels, 225/60R18 belongs to 18-inch wheels, and the SRT8 uses 20-inch wheels with 245/45R20 front and 255/45R20 rear tire sizes.
Wheel diameter needs to be confirmed before shopping by tire size, especially on a car that may no longer be on its original wheel package. Looking at the sidewall size marking and physically verifying the installed wheel is the safest way to avoid mixing a correct Chrysler 300 tire size with the wrong rim diameter.
Why does the 2007 Chrysler 300 have more than one tire size?
The 2007 Chrysler 300 covers several trim and drivetrain combinations, so tire fitment changes with the wheel package used on each version. Base and some Touring models use 17-inch tires, several C and Limited trims use 18-inch tires, and the SRT8 steps up to a 20-inch staggered arrangement with separate front and rear sizes.
That means the correct replacement choice is tied to the exact configuration rather than the Chrysler 300 name alone. Buyers should identify the sub-model first, then confirm whether the car still has its original wheel diameter, since later wheel changes can make the current setup different from the stock trim fitment.
Choosing the Right Tire
What should I consider when choosing a 245/45R20 tire for a 2007 Chrysler 300?
On a 2007 Chrysler 300, 245/45R20 is tied to the front fitment used on SRT8 applications. The main selection points are keeping the correct front size, confirming the 20-inch wheel setup, and comparing the available radial choices by series, sidewall treatment, rim-width specification, and load details where those figures are given.
This size has meaningful variety, including blackwall, redline, and RWL presentations from BFGoodrich, Nitto, and Pro-Trac. Buyers trying to preserve the SRT8's intended staggered layout should also make sure the rear tires remain in the correct companion size, because front and rear selection work together on this application.
What sidewall styles are available for 2007 Chrysler 300 tires?
The clearest sidewall variation for the 2007 Chrysler 300 appears in the 20-inch SRT8 sizes, where blackwall, redline, and RWL options are available. Blackwall gives a more understated modern look, while redline and raised white letter sidewalls create a more assertive visual presentation on the larger-wheel Chrysler 300 setup.
Sidewall style does not change the need to stay with the correct tire size for the sub-model and wheel diameter. It is best treated as an appearance choice after the fitment basics are settled, especially on SRT8 cars where the front and rear sizes differ and the overall look depends on keeping the staggered combination intact.
What brands offer tires for the 2007 Chrysler 300?
For the 20-inch Chrysler 300 fitments, available brands include BFGoodrich, Nitto, and Pro-Trac. Those choices appear in the 245/45R20 and 255/45R20 sizes used on SRT8 applications, with several tire series represented, including g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, NT555 G2, and Street Pro III.
Brand comparison should come after the correct size and wheel setup are confirmed. A buyer deciding among these options can then focus on factors such as sidewall treatment, stated rim-width range where it is provided, and whether the goal is a subtle blackwall presentation or a more distinctive redline or raised white letter look.
Restoration & Appearance
Which tire should I choose for a period-style 2007 Chrysler 300?
A period-style 2007 Chrysler 300 tire choice starts with using the exact size that matches the car's trim and wheel diameter. From there, the 20-inch SRT8 fitments offer the most visual character, with Pro-Trac Street Pro III options in redline and RWL alongside blackwall choices from BFGoodrich and Nitto.
Appearance decisions should still respect the way the car is actually configured today. A Chrysler 300 kept close to its original trim setup will usually look most coherent when the tire size, wheel diameter, and sidewall treatment all match the stance and personality of that specific version rather than borrowing a style from another sub-model.
How does tire construction affect the appearance of a restored 2007 Chrysler 300?
The 2007 Chrysler 300 uses radial tires across its primary fitments, so construction choice is less about bias-ply versus radial appearance and more about the way modern radial designs present themselves on the car. On SRT8 sizes in particular, blackwall, redline, and RWL options can change the visual character more than construction itself.
For an appearance-focused Chrysler 300, the bigger question is whether the car is being kept in a clean contemporary style or given a more expressive muscle-sedan look. Matching the sidewall treatment to the wheel size and trim level usually has more impact than chasing a different construction type on this particular model year.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2007 Chrysler 300?
Yes. A 2007 Chrysler 300 can be affected by aftermarket wheels, suspension changes, ride-height alterations, or body modifications, especially because this model year already spans 17-inch, 18-inch, and 20-inch factory-type fitments. The SRT8 adds another layer of complexity by using a staggered setup with different front and rear tire sizes.
Any modified car should be checked for wheel diameter, wheel width, and clearance before replacement tires are chosen. Steering clearance up front and fender or suspension clearance at the rear become especially important on 20-inch applications, where using the correct front-to-rear size relationship helps preserve the intended fitment balance.
What should I inspect before driving a 2007 Chrysler 300 on new tires?
Before driving a 2007 Chrysler 300 on new tires, inspect the wheels for damage, confirm that the tire sizes match the trim and axle position, and check inflation pressure carefully. It also helps to look over suspension and steering components, since worn parts can affect tracking, alignment behavior, and tire wear soon after installation.
A short initial road test is a smart follow-up, especially on an SRT8 with front and rear tires in different sizes. Any rubbing, pull, vibration, or unusual clearance issue should be addressed early, and an alignment check is worthwhile if the car has recently had suspension work, wheel changes, or uneven wear on the previous tires.
How often should tires on a 2007 Chrysler 300 be inspected?
Tires on a 2007 Chrysler 300 should be inspected regularly, not just when tread appears low. Pressure loss, irregular wear, cuts, bulges, and sidewall cracking are all worth checking, and a car that sees occasional use should still be looked over before longer drives because time and storage conditions can affect tire condition.
Inspection matters even more when the car uses 20-inch SRT8 tires, since a staggered setup can hide wear differences between the front and rear. Keeping a close eye on condition, air retention, and visible clearance helps catch problems early, especially if the Chrysler 300 has been parked for long periods or has non-original wheels.
