The 2006 Chrysler 300 brought a bold, upright sedan shape back into the American market, blending rear-wheel-drive proportions with modern luxury and, in SRT8 form, serious performance intent. That wide spread of personalities is exactly why tire fitment matters on this car. Depending on the sub-model, the 2006 Chrysler 300 uses 215/65R17, 225/60R18, 245/45R20, or 255/45R20 radial tires, with wheel diameter and even front-to-rear sizing changing across the lineup. The available choices also vary by brand, tire series, and sidewall treatment, especially in the 20-inch fitments. Getting the right tire starts with confirming the exact trim and wheel setup on the car.
Which Tire Size Is Right for The 2006 Chrysler 300
The 2006 Chrysler 300 uses four different tire sizes, and the correct one depends on the exact sub-model and wheel diameter. Sizes range across 17-inch, 18-inch, and 20-inch rims, and the C SRT8 adds a staggered setup with different front and rear sizes. Before choosing a tire, confirm the trim level and the actual wheels on the car, especially if it has been changed from its original configuration.
215/65R17 is a metric radial size: 215 is the section width in millimeters, 65 is the aspect ratio, R identifies radial construction, and 17 is the wheel diameter in inches. On the 2006 Chrysler 300, this size suits the 17-inch wheel fitments used on certain Base, Limited (RWD), and Touring (RWD) configurations. Its role in this lineup is straightforward, with an emphasis on matching the correct wheel diameter and overall fitment rather than sorting through appearance-driven variations. It is the right size to evaluate when the car retains its 17-inch setup and stock-style proportions.
225/60R18 is a metric radial size with a 225-millimeter nominal section width, a 60-series profile, and an 18-inch rim diameter. For the 2006 Chrysler 300, this size applies to certain 18-inch configurations, including the C, Limited (AWD), and Touring (AWD). This fitment keeps the buyer's attention on confirming the exact sub-model and wheel package, since it is different from both the 17-inch standard setups and the 20-inch performance applications. Choose this size only after verifying that the car is actually on its intended 18-inch wheels.
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 2006 Chrysler 300, this size is tied to the C SRT8 front fitment and appears where a larger, lower-profile performance-oriented setup is required. Product choice is broader here, with BFGoodrich, Nitto, and Pro-Trac options, plus Blackwall, Redline, and RWL sidewall treatments across series such as g-Force and Street Pro III. It is the size to evaluate when the car uses the SRT8 front wheel position or a matching 20-inch front setup.
255/45R20 is a metric radial size with a wider 255-millimeter section width, the same 45-series profile family, and a 20-inch rim diameter. On the 2006 Chrysler 300, this size is used at the rear of the C SRT8, making it part of the car's staggered 20-inch arrangement rather than a universal 300 fitment. Available choices include BFGoodrich, Nitto, and Pro-Trac tires, with Blackwall, Redline, and RWL sidewall styles depending on the series. This is the rear size to confirm when maintaining the SRT8's front-to-rear tire relationship and overall stance.
Tire fitment on the 2006 Chrysler 300 varies by sub-model, drivetrain, and in SRT8 form, by axle position as well. Checking the exact trim matters because the lineup spans three wheel diameters and includes both square and staggered tire setups.

2006 Chrysler 300 Base
The 2006 Chrysler 300 Base uses the 215/65R17 radial size on a 17-inch wheel setup. Tire selection here is mainly about keeping the correct metric size and confirming that the car still has its original wheel diameter if it has seen wheel or suspension changes.
The 2006 Chrysler 300 C uses the 225/60R18 radial size. That makes the decision more about matching the correct 18-inch fitment than sorting through multiple primary sizes, especially if the car has been upgraded or altered since new.
The 2006 Chrysler 300 C SRT8 uses a 20-inch radial setup, with 245/45R20 at the front and 255/45R20 at the rear. Tire selection should preserve that front-to-rear sizing relationship unless the wheel package has been changed and the full setup has been rechecked.
The front position on the 2006 Chrysler 300 C SRT8 uses 245/45R20 radial tires. That gives the buyer access to several brands, tire series, and sidewall treatments, but the front fitment still needs to be matched to the correct 20-inch wheel width and overall axle setup.
The rear position on the 2006 Chrysler 300 C SRT8 uses 255/45R20 radial tires. Keeping that wider rear size in place is part of maintaining the intended staggered arrangement, so rear tire selection should be made with the front size and wheel combination in mind.
The 2006 Chrysler 300 Limited (AWD) uses 225/60R18 radial tires. The key step is verifying that the car remains on its correct 18-inch AWD wheel setup before comparing available replacement tires.
The 2006 Chrysler 300 Limited (RWD) uses the 215/65R17 radial size. That makes correct wheel diameter and overall tire dimensions the main concerns, particularly on cars that may have been switched to larger aftermarket wheels.
The 2006 Chrysler 300 Touring (AWD) uses 225/60R18 radial tires. Tire choice starts with preserving that 18-inch AWD fitment and then checking whether the current wheels still match the intended size and width.
The 2006 Chrysler 300 Touring (RWD) uses 215/65R17 radial tires. Buyers should treat this as a 17-inch fitment first, then confirm wheel condition and overall setup before selecting a replacement 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 2006 Chrysler 300?
A 2006 Chrysler 300 can use 215/65R17, 225/60R18, 245/45R20, or 255/45R20, depending on the exact sub-model and wheel setup. Base, Limited (RWD), and Touring (RWD) use 215/65R17, while the C, Limited (AWD), and Touring (AWD) use 225/60R18. The C SRT8 uses 245/45R20 at the front and 255/45R20 at the rear.
That means the first step is identifying the trim level and checking the actual wheels on the car. A Chrysler 300 with aftermarket wheels, replacement rims, or an SRT8-style conversion may no longer match its original setup, so wheel diameter and front-to-rear sizing should be confirmed before choosing tires.
What size rim does a 2006 Chrysler 300 use?
The 2006 Chrysler 300 uses three rim diameters across the lineup: 17-inch, 18-inch, and 20-inch. The 215/65R17 fitment uses a 17-inch wheel, the 225/60R18 fitment uses an 18-inch wheel, and both SRT8 sizes, 245/45R20 and 255/45R20, use 20-inch wheels.
Rim diameter is the quickest way to narrow the correct tire size, but it is not the only check that matters. On the SRT8, the front and rear both use 20-inch wheels yet require different tire widths, so buyers should confirm both axle position and wheel width before selecting replacements.
Why does the 2006 Chrysler 300 have more than one tire size?
The 2006 Chrysler 300 was offered in several trims with different wheel packages, so tire size changes with the model. Some versions use 17-inch wheels, others use 18-inch wheels, and the C SRT8 moves to a 20-inch setup with different front and rear tire sizes.
This variety means tire choice is tied to the exact configuration rather than the Chrysler 300 name alone. Trim badge, drivetrain, wheel diameter, and on SRT8 models the axle position all matter, so it is worth checking the current car carefully instead of assuming one size fits the whole range.
Choosing the Right Tire
What should I consider when choosing a 245/45R20 or 255/45R20 tire for a 2006 Chrysler 300?
Start by matching the tire to the correct axle position and wheel size. On the 2006 Chrysler 300 C SRT8, 245/45R20 is the front size and 255/45R20 is the rear size, so the selection process is about keeping that staggered arrangement intact while comparing radial tire choices within each size.
After size, look at brand, tire series, sidewall style, and wheel-width compatibility where it is stated. Some 20-inch options are Blackwall only, while others add Redline or RWL styling, so the right pick depends on whether the goal is a restrained appearance, a more performance-oriented look, or a custom presentation.
What sidewall styles are available for 2006 Chrysler 300 tires?
In the available 20-inch Chrysler 300 fitments, sidewall styles include Blackwall, Redline, and RWL. Blackwall choices appear across BFGoodrich and Nitto performance-oriented tires, while Pro-Trac Street Pro III adds Redline and RWL options in both 245/45R20 and 255/45R20.
Sidewall style mainly changes the visual character of the car rather than the underlying fitment size. Buyers preserving an understated modern look may lean toward Blackwall, while Redline or raised white letter sidewalls can push the SRT8 toward a more aggressive or custom appearance, provided the correct size is maintained.
What brands offer tires for the 2006 Chrysler 300?
For the available 20-inch fitments on the 2006 Chrysler 300, brands include BFGoodrich, Nitto, and Pro-Trac. Those brands appear in 245/45R20 and 255/45R20 sizes, covering several tire series and giving SRT8 owners more than one path when replacing front and rear tires.
Brand alone should not drive the decision. It makes more sense to compare the exact size, sidewall treatment, tire series, and any stated rim-width or load details so the tire matches the car's wheel setup and the owner's preferred balance of appearance and intended use.
Restoration & Appearance
Which tire should I choose for a period-style 2006 Chrysler 300?
A period-style 2006 Chrysler 300 tire choice starts with preserving the correct original-size format for the specific trim. That means 215/65R17 on certain RWD models, 225/60R18 on some C and AWD variants, or the staggered 245/45R20 front and 255/45R20 rear setup on the C SRT8.
Once the size is correct, appearance becomes the next filter. A Blackwall tire keeps the look closer to the restrained factory-era presentation of many modern sedans, while Redline or RWL options can create a more personalized SRT8-style statement. Exact originality questions are best checked against vehicle-specific brochures or marque references.
How does tire construction affect the appearance of a restored 2006 Chrysler 300?
On the 2006 Chrysler 300, construction is simpler than on older collector cars because the primary fitments are radial tires throughout the lineup. The visual differences come less from bias-ply versus radial choice and more from the tire's profile, wheel diameter, and sidewall treatment within the correct modern metric size.
That makes wheel-and-tire proportion especially important on a clean, restoration-minded car. A 17-inch or 18-inch setup gives a different visual balance than the SRT8's 20-inch arrangement, and sidewall style can further shift the character, so preserving the intended trim-specific sizing usually matters more than chasing novelty.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2006 Chrysler 300?
Yes. A 2006 Chrysler 300 can be sensitive to wheel and tire changes because the lineup already uses several factory sizes across 17-inch, 18-inch, and 20-inch applications. Cars with aftermarket wheels, lowered suspension, spacer changes, or SRT8-style conversions may no longer have the same clearance or wheel-width relationship as stock examples.
That is why the current setup should be checked before ordering replacement tires. Measure the wheel diameter, confirm the installed tire size at each axle, and look at fender, steering, and suspension clearance so the new tire matches the car as it sits now rather than how it left the factory.
What should I inspect before driving a 2006 Chrysler 300 on new tires?
Check the wheel condition, valve stems, air pressure, and the tire size installed at each position before putting miles on a 2006 Chrysler 300. It is also smart to inspect alignment-related wear, brake clearance, and on C SRT8 models, whether the staggered front and rear sizes have been mounted in the proper locations.
A short road test should follow installation so any vibration, rubbing, or steering pull is caught early. Collector and enthusiast cars that sit for long periods deserve an extra look for age-related issues elsewhere on the chassis, since fresh tires perform best when the suspension and alignment are in good order.
What should I check before a longer drive in a 2006 Chrysler 300?
Before a longer drive, confirm that all four tires on the 2006 Chrysler 300 are inflated properly, free from cuts or bulges, and showing even tread wear. The tire size should match the correct trim and wheel package, and SRT8 models should retain the proper 245/45R20 front and 255/45R20 rear arrangement.
Longer trips also make it worth checking for slow air loss and looking over the spare or roadside equipment if the car still carries it. A vehicle that has spent time parked should get extra attention for age cracking and flat spotting, since storage-related tire issues often appear before highway use.
