The 2009 Dodge Challenger brought Mopar muscle back in modern form, blending retro-inspired styling with contemporary chassis, braking, and powertrain hardware. For many owners, that mix creates a tire decision that is less about recreating an older bias-ply look and more about matching the exact trim and wheel package on the car today. The 2009 Dodge Challenger uses radial tire fitments only, with several metric sizes spanning 17-, 18-, and 20-inch rims across SE, R/T, and SRT8 configurations. Available choices include blackwall, redline, and raised white letter presentations in selected 20-inch sizes. The key is confirming the exact sub-model and wheel setup before comparing appearance, series, and road-use priorities.
Which Tire Size Is Right for The 2009 Dodge Challenger
Five primary tire sizes apply to the 2009 Dodge Challenger, and the correct one depends on the sub-model and wheel package. Sizes vary across SE, R/T, and SRT8 applications, and this car uses more than one rim diameter, so the first step is confirming both the exact trim and whether the car is on 17-, 18-, or 20-inch wheels before choosing among the available radial tire options.
235/55R18 is a metric radial size with a 235-millimeter nominal section width, a 55-series aspect ratio, and fitment for an 18-inch rim. On the 2009 Dodge Challenger, this size is used on certain R/T applications and reflects the modern radial construction that defines this model year's primary fitments. Compared with the 20-inch options, it represents a different wheel-and-tire package rather than a simple styling variation. Choosing this size starts with verifying that the car actually carries the 18-inch wheel setup, especially if wheels have been changed since new.
245/45R20 is a metric radial size that combines a 245-millimeter nominal width with a 45-series profile on a 20-inch rim. This size appears on 2009 Dodge Challenger R/T and SRT8 applications, and it is one of the most developed choices in the available product range. BFGoodrich, Nitto, and Pro-Trac options are available here, with blackwall, redline, and raised white letter sidewall treatments across series such as g-Force and Street Pro III. It is a strong comparison point for owners focused on both 20-inch fitment accuracy and appearance selection.
215/65R17 is a metric radial size with a 215-millimeter nominal section width, a 65-series aspect ratio, and fitment for a 17-inch rim. On the 2009 Dodge Challenger, this size belongs to certain SE configurations and should be treated as a distinct trim-level fitment rather than an interchangeable substitute for the larger-wheel packages. Its taller sidewall profile follows the sizing convention used on the 17-inch setup, which gives the buyer a different baseline than the 18- and 20-inch combinations. Selection begins with confirming that the car still retains its original 17-inch wheel diameter.
225/60R18 is a metric radial tire size using a 225-millimeter nominal width, a 60-series aspect ratio, and an 18-inch rim. This fitment appears on certain 2009 Dodge Challenger SE models and reflects a different wheel package from the SE cars that use 215/65R17. That makes it important to distinguish wheel diameter before comparing tires, since the 17-inch and 18-inch SE applications are not the same decision. Buyers looking at this size should confirm the actual wheel on the car first, then compare radial options appropriate to that 18-inch configuration.
255/45R20 is a metric radial size with a 255-millimeter nominal section width, a 45-series profile, and fitment for a 20-inch rim. On the 2009 Dodge Challenger, it serves the SRT8 rear application, so its role is tied to that specific staggered 20-inch setup rather than to the whole model line. Available choices include BFGoodrich, Nitto, and Pro-Trac products, with blackwall, redline, and raised white letter sidewall treatments depending on the series. This size should be evaluated with the rear wheel specification in mind, especially on cars where wheel width or suspension setup may have been altered.
Sub-model fitment matters on the 2009 Dodge Challenger because tire size changes with trim and wheel package, not just with model year. SE, R/T, and SRT8 applications do not all use the same setup, so confirming the exact version of the car is the clearest way to narrow the correct radial tire size.

2009 Dodge Challenger R/T
The 2009 Dodge Challenger R/T uses either an 18-inch or 20-inch radial tire setup, so tire selection starts with confirming which wheel package is on the car. That affects both the correct size and the range of available product styles, especially if appearance details such as blackwall, redline, or raised white letter sidewalls matter.
The 2009 Dodge Challenger SE uses two different radial fitments depending on whether the car has a 17-inch or 18-inch wheel package. That makes wheel-diameter confirmation especially important before comparing tires, since the choice is tied to the actual setup on the car rather than to SE badging alone.
The 2009 Dodge Challenger SRT8 uses a 20-inch radial setup and should be checked carefully because front and rear sizing can differ. Tire choice here often involves balancing correct staggered fitment with sidewall appearance and series selection in the available 20-inch products.
The 2009 Dodge Challenger SRT8 Front uses the 245/45R20 radial size as part of the car's 20-inch performance-oriented layout. Front-tire selection should be matched to the actual wheel and paired thoughtfully with the rear size so the staggered setup remains consistent.
The 2009 Dodge Challenger SRT8 Rear uses the wider 255/45R20 radial size on a 20-inch rim. Rear fitment should be chosen with the staggered arrangement in mind, especially when comparing series, sidewall treatments, and any wheel changes made since the car was built.
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 2009 Dodge Challenger?
A 2009 Dodge Challenger can use 215/65R17, 225/60R18, 235/55R18, 245/45R20, or 255/45R20, depending on the sub-model and wheel setup. SE applications use either 215/65R17 or 225/60R18, R/T uses 235/55R18 or 245/45R20, and SRT8 applications use 245/45R20 at the front with 255/45R20 at the rear in the staggered setup.
The main takeaway is that there is no single tire size for every 2009 Challenger. Start by confirming the exact trim and measuring the wheel diameter on the car, especially if it has been modified or fitted with different wheels. That step separates the correct 17-, 18-, and 20-inch options before any comparison of brand, sidewall style, or tire series begins.
What size rim does a 2009 Dodge Challenger use?
The 2009 Dodge Challenger uses three rim diameters across its factory fitments: 17-inch, 18-inch, and 20-inch. SE models can be found with 17- or 18-inch setups, R/T applications use 18- or 20-inch setups, and SRT8 applications use 20-inch wheels with separate front and rear tire sizes in the staggered arrangement.
Rim diameter is the first thing to verify before ordering tires, because a 17-inch tire cannot be mounted on an 18-inch wheel, and an 18-inch tire cannot be mounted on a 20-inch wheel. Wheel changes are common on modern muscle cars, so checking the actual wheel on the car matters more than relying only on trim name or appearance.
Why does the 2009 Dodge Challenger have more than one tire size?
The 2009 Dodge Challenger has more than one tire size because Dodge used different wheel-and-tire packages across the SE, R/T, and SRT8 lineup. Some trims offered more than one wheel diameter, and the SRT8 uses a staggered arrangement with 245/45R20 in front and 255/45R20 in the rear rather than the same size at all four corners.
That means tire selection is tied to the car's exact configuration, not just the model year. A buyer should confirm the sub-model, then confirm the wheel diameter, and on SRT8 applications also confirm whether the front and rear wheels still follow the original staggered pattern. Those checks prevent choosing a size meant for a different Challenger setup.
Choosing the Right Tire
What should I consider when choosing a 245/45R20 tire for a 2009 Dodge Challenger?
A 245/45R20 tire for a 2009 Dodge Challenger should first match the car's actual 20-inch wheel setup and intended position on the vehicle. This size appears on certain R/T applications and on the SRT8 front, and the available choices include BFGoodrich, Nitto, and Pro-Trac products across blackwall, redline, and raised white letter presentations.
Once the size is confirmed, compare tire series, sidewall style, and wheel-width compatibility where that specification is given. On some 245/45R20 products, the supported rim-width range is 7.5 to 9.0 inches. That matters on cars with aftermarket wheels, and it helps narrow the right choice for an owner who cares as much about appearance as road-use character.
What sidewall styles are available for 2009 Dodge Challenger tires?
Available sidewall styles for 2009 Dodge Challenger tires include blackwall, redline, and RWL, or raised white letter, in the supported 20-inch product range. Those appearance choices are offered in 245/45R20 and 255/45R20 selections, giving owners some flexibility between a cleaner modern look and a more overt muscle-car presentation.
Sidewall style does not replace the need to match the correct size and wheel diameter. It comes after fitment is settled. For an owner refining the look of an R/T or SRT8, these treatments can noticeably change the car's visual character, so it helps to decide early whether the goal is understated blackwall or a more nostalgic redline or lettered sidewall appearance.
What brands offer tires for the 2009 Dodge Challenger?
BFGoodrich, Nitto, and Pro-Trac offer tires in the available 20-inch Challenger fitments covered here. The product range includes series such as g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, Nitto NT555 G2, and Pro-Trac Street Pro III, giving the buyer several different product families within the correct 20-inch sizes.
Brand choice should be treated as one part of the decision rather than the whole answer. After confirming whether the car needs 245/45R20 or 255/45R20, compare sidewall style, supported rim width where stated, and any load or weight details that matter to your setup. That keeps the process centered on fitment and intended use instead of choosing by name alone.
Restoration & Appearance
Which tire should I choose for a period-style 2009 Dodge Challenger?
A period-style 2009 Dodge Challenger usually starts with the correct trim-specific radial size and the wheel diameter actually on the car. Since this model uses modern radial fitments rather than vintage bias-ply sizes, the appearance decision often comes down to choosing among the available 20-inch tire series and whether a blackwall, redline, or raised white letter sidewall best suits the car.
For a more faithful early modern-muscle presentation, keep the selection tied closely to the Challenger's original trim and wheel package rather than treating all 20-inch tires the same. Owners pursuing a highly exact restoration should also compare the car against marque references, period photography, or build-specific documentation before treating any single sidewall treatment as definitive.
How does tire construction affect the appearance of a restored 2009 Dodge Challenger?
Tire construction has less visual impact on a restored 2009 Dodge Challenger than it would on an older collector car because the primary fitments for this model year are already radial. The bigger appearance differences come from tire size, wheel diameter, sidewall profile, and whether the tire uses a blackwall, redline, or raised white letter sidewall treatment.
That means restoration-minded owners should focus first on preserving the correct 17-, 18-, or 20-inch stance for the exact trim. A mismatched wheel diameter or the wrong front-to-rear relationship on an SRT8 will change the car's look more than the radial construction itself. Sidewall presentation then becomes the finishing detail that shapes the overall visual impression.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2009 Dodge Challenger?
Yes, modifications can affect tire fitment on a 2009 Dodge Challenger even when the size sounds close to the original specification. Aftermarket wheels can change width or offset, suspension changes can alter clearance, and body or brake modifications can also affect how much room is available around the tire, especially on 20-inch setups and staggered SRT8 applications.
A modified Challenger should be checked at the wheel and car level before any tire is chosen. Measure the actual wheel diameter and width, confirm front and rear sizes separately on staggered cars, and inspect steering and fender clearance through the full range of motion. Those steps matter far more than assuming a stock tire size will behave the same on a changed setup.
What should I inspect before driving a 2009 Dodge Challenger on new tires?
Before driving a 2009 Dodge Challenger on new tires, inspect wheel condition, valve stems, lug hardware, and the overall condition of the suspension and alignment-related components. The tires themselves should be checked for proper inflation, accurate front and rear placement, and adequate clearance around fenders, liners, and steering components once mounted on the car.
That inspection is especially important on an SRT8 with separate front and rear sizes, or on any Challenger that may have aftermarket wheels. A short, careful test drive can help reveal rubbing, vibration, or pull that was not obvious at installation. Catching those issues early helps protect the new tires and confirms that the car's setup matches the selected fitment.
How often should tires on a 2009 Dodge Challenger be inspected?
Tires on a 2009 Dodge Challenger should be inspected regularly, not just when tread looks low. Check them for air loss, uneven wear, cuts, bulges, cracking, and any sign of contact with suspension or body parts. Cars that see seasonal use or long storage periods still need routine inspection because aging and pressure loss can happen even with limited mileage.
A practical habit is to inspect the tires before longer drives and during normal pressure checks. On an SRT8, make sure the front and rear sizes remain in their proper positions and wear evenly as a set. Any change in ride feel, steering response, or visible sidewall condition is a reason to inspect more closely before putting more road miles on the car.
