The 2002 Chrysler 300M belongs to the era when Chrysler was giving its full-size sedan line a more assertive, sport-luxury character, blending front-wheel-drive practicality with a distinctly cab-forward profile. It appeals to owners who want modern road manners without losing the model’s clean early-2000s identity. Tire fitment centers on two radial sizes, with 225/55R17 used on the Base and Performance Package cars and 245/45R18 used on the 300M Special. That creates a real choice between standard and Special-model fitment, along with different product personalities ranging from blackwall performance tires to Silvertown Radials with whitewall or redline styling. The key is matching the tire to the car’s exact sub-model, wheel diameter, and intended look.
Which Tire Size Is Right for The 2002 Chrysler 300M
The 2002 Chrysler 300M uses two primary tire sizes, and the correct one depends on the exact sub-model and wheel diameter. Base models and cars with the Performance Package use 225/55R17 on a 17-inch rim, while the 300M Special uses 245/45R18 on an 18-inch rim. Before comparing tire series or sidewall styles, confirm whether the car has the standard 17-inch setup or the Special-model 18-inch package.
The 225/55R17 size is a modern metric radial: 225 is the nominal section width in millimeters, 55 is the aspect ratio, R indicates radial construction, and 17 is the rim diameter in inches. On the 2002 Chrysler 300M, this size supports the standard 17-inch wheel fitment used on the Base and Performance Package configurations. Available choices include BFGoodrich performance-oriented g-Force series as well as Silvertown Radial options in blackwall-related performance styling, wide whitewall, and redline presentations. This size makes sense when preserving the car’s standard wheel setup while deciding whether the priority is contemporary handling character or a more distinctive visual treatment.
The 245/45R18 size is also a modern metric radial, with a wider 245-millimeter section width, a 45-series profile, radial construction, and an 18-inch rim diameter. For the 2002 Chrysler 300M, this size belongs to the Special model and should be treated as a separate fitment path rather than an alternative for every 300M. Product choices in this size focus on blackwall performance tires, including BFGoodrich g-Force series options and the Nitto NT555 G2. It is the right size to evaluate when the car already has the Special-model 18-inch wheel setup and the goal is to maintain that lower-profile, performance-oriented presentation.
Sub-model fitment matters on the 2002 Chrysler 300M because wheel diameter and tire size are not the same across the range. The Base and Performance Package cars share one setup, while the 300M Special moves to a different size on a different rim diameter.

2002 Chrysler 300M Base
The 2002 Chrysler 300M Base uses the 225/55R17 radial fitment on a 17-inch wheel. Tire selection here is mostly about choosing the right product style, whether that means a straightforward blackwall performance radial or a more appearance-driven wide whitewall or redline option.
The 2002 Chrysler 300M Special uses 245/45R18 radials on an 18-inch wheel, making it the distinct fitment within the 300M lineup. That means tire shopping starts with confirming the Special-model wheel package, then comparing the available blackwall performance-oriented choices within that exact size.
The 2002 Chrysler 300M w/Performance Pkg. uses the same 225/55R17 radial tire size as the Base model. That keeps fitment straightforward, but wheel width, tire series, and sidewall appearance still matter when narrowing the choice to match the car’s use and presentation.
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 2002 Chrysler 300M?
The 2002 Chrysler 300M uses two tire sizes, and the correct one depends on the sub-model. Base models use 225/55R17 radials, the 300M Special uses 245/45R18 radials, and the 300M w/Performance Pkg. also uses 225/55R17 radials.
That means the first step is confirming exactly which 300M you have and which wheels are on the car now. A Base or Performance Package car should not be treated the same as a Special simply because they share the same model name, since the rim diameter and tire size are different.
What size rim does a 2002 Chrysler 300M use?
A 2002 Chrysler 300M uses either a 17-inch or 18-inch rim, depending on the sub-model. The 225/55R17 fitment uses a 17-inch rim, while the 245/45R18 fitment used on the 300M Special requires an 18-inch rim.
Rim diameter is the first thing to verify before comparing tires, because a 17-inch tire cannot mount on an 18-inch wheel and vice versa. It also helps to confirm the actual wheel setup on the car, especially if it has been changed over the years or fitted with aftermarket wheels.
Do all 2002 Chrysler 300M sub-models use the same tire size?
No, the 2002 Chrysler 300M does not use one tire size across every sub-model. The Base and 300M w/Performance Pkg. use 225/55R17, while the 300M Special uses the larger 245/45R18 fitment.
That difference matters because the Special model follows a different wheel-and-tire path from the standard 17-inch cars. Anyone replacing tires should confirm the sub-model name and the wheel diameter already on the vehicle before assuming that any 300M tire option will suit the car.
Choosing the Right Tire
What should I consider when choosing a 2002 Chrysler 300M tire?
Start with the correct size for the car’s sub-model: 225/55R17 for the Base and Performance Package cars, or 245/45R18 for the Special. From there, compare radial construction details such as tire series, sidewall style, approved rim-width range, and any load information tied to the product.
The right choice depends on how the car is used and how you want it to look. A blackwall performance radial suits a more contemporary presentation, while a Silvertown Radial in 225/55R17 adds a stronger visual statement through whitewall or redline styling without changing the primary tire size.
What sidewall styles are available for 2002 Chrysler 300M tires?
Sidewall style depends on the tire size. In 225/55R17, available choices include Blackwall, Wide Whitewall, and Redline. In 245/45R18, the available products are blackwall performance radials, which keeps the Special model’s choices focused on a more modern, low-profile look.
That makes sidewall appearance part of the decision, especially on standard 17-inch 300M models. A whitewall or redline changes the car’s visual character noticeably, while blackwall tires keep the presentation cleaner and more contemporary. The sidewall should match both the wheel setup and the overall style goal for the car.
What brands offer tires for the 2002 Chrysler 300M?
Tires for the 2002 Chrysler 300M are available from BFGoodrich and Nitto. BFGoodrich appears in both 225/55R17 and 245/45R18, while Nitto appears in 245/45R18 for the 300M Special fitment.
Brand is only one part of the decision. It still helps to compare the specific tire series, sidewall treatment, rim-width compatibility, and the overall character of the tire in the size your 300M uses. A Base car and a Special may share brand names, but they do not share the same size or wheel diameter.
Restoration & Appearance
Which tire should I choose for a period-style 2002 Chrysler 300M?
A period-style approach starts with keeping the correct size for the specific 2002 Chrysler 300M sub-model. For Base and Performance Package cars, 225/55R17 offers the broadest appearance range, including BFGoodrich Silvertown Radial options alongside modern blackwall performance tires. The 300M Special stays with 245/45R18 blackwall performance styling.
The visual goal matters as much as the size. A standard blackwall keeps the look closer to an early-2000s sport-sedan presentation, while a whitewall or redline creates a more customized or collector-focused appearance. Anyone chasing exact historical presentation should also compare tire appearance against period photos, brochures, or marque-specific references.
How does tire construction affect the appearance of a restored 2002 Chrysler 300M?
On the 2002 Chrysler 300M, tire construction is straightforward because the primary fitments are radial. The bigger appearance difference comes from the tire’s profile and sidewall treatment, especially in 225/55R17 where blackwall, wide whitewall, and redline options can give the car very different visual character.
A blackwall performance radial tends to preserve the 300M’s original-era sport-luxury feel, while whitewall or redline styling pushes the car toward a more individualized presentation. The cleaner the restoration goal, the more important it becomes to keep the proper size and wheel diameter matched to the exact sub-model before making appearance-driven changes.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2002 Chrysler 300M?
Yes, modifications can affect tire fitment on a 2002 Chrysler 300M even when the tire size itself is correct. Aftermarket wheels, suspension changes, altered ride height, or body and steering-component changes can all influence how a 225/55R17 or 245/45R18 tire sits and clears.
That is why the actual wheel diameter and width on the car should be checked before ordering replacement tires. Clearance at full steering lock and through suspension travel also matters, particularly if the car no longer has its original wheel-and-suspension setup. A modified 300M should always be measured as it sits now.
What should I inspect before driving a 2002 Chrysler 300M on new tires?
Before driving a 2002 Chrysler 300M on new tires, inspect the wheels for damage, confirm the tire size matches the sub-model, and check that each tire is inflated properly for the vehicle’s setup. It also makes sense to verify valve stems, lug torque, and overall wheel condition before road use.
A short test drive should include listening for rubbing, vibration, or pulling, especially if the car has replacement wheels or suspension changes. After that initial drive, recheck tire pressure and give the tires a quick visual inspection. Catching a clearance or mounting issue early is much easier than discovering it on a longer trip.
How often should tires on a 2002 Chrysler 300M be inspected?
Tires on a 2002 Chrysler 300M should be inspected regularly, not just when tread looks worn. Collector and low-mileage cars can develop problems from age, storage, or long periods of sitting, so sidewalls, tread surfaces, and air pressure deserve routine attention even when the car is driven infrequently.
A consistent inspection habit helps catch cracking, bulges, cuts, uneven wear, or slow air loss before those issues become road problems. It is also smart to inspect the tires before any highway drive or extended trip. The 300M is a substantial sedan, so tire condition and pressure have a direct effect on confidence and comfort.
