The 2006 Dodge Magnum brought station-wagon practicality into the modern muscle era, pairing a long roof and bold stance with rear-drive Chrysler LX architecture and, in some trims, serious V8 performance. That mix means tire choice on a 2006 Dodge Magnum is closely tied to the exact trim and wheel package, not just the model name alone. Depending on sub-model, Magnum fitment ranges from 215/65R17 and 225/60R18 to staggered 20-inch SRT8 sizing with 245/45R20 front and 255/45R20 rear radials. Sidewall and series choices also vary, especially in the 20-inch sizes. The right selection starts with confirming trim, wheel diameter, and whether the goal is stock-style fitment or a more customized presentation.
Which Tire Size Is Right for The 2006 Dodge Magnum
The 2006 Dodge Magnum uses four primary tire sizes, and the correct one depends on sub-model and wheel diameter. Some trims share a common 17-inch or 18-inch radial size, while the SRT8 uses 20-inch fitment, including a staggered setup with different front and rear sizes. The first step is confirming the exact sub-model and verifying whether the car has 17-inch, 18-inch, or 20-inch wheels before comparing tire choices.
Fit(s): R/T (AWD), R/T (RWD), SXT (AWD), and SXT (RWD)
Construction: Radial|Rim: 18 in
225/60R18 is a metric radial size in which 225 is the section width in millimeters, 60 is the aspect ratio, R identifies radial construction, and 18 is the wheel diameter in inches. On the 2006 Dodge Magnum, this size suits several 18-inch applications and keeps the tire choice centered on proper trim and wheel confirmation rather than construction changes. The main buying differences come from how the vehicle is equipped, since product variety is more pronounced in the 20-inch performance sizes. This size is the right place to start when an R/T or certain SXT and AWD configurations are running 18-inch wheels.
215/65R17 is a metric radial size with a 215-millimeter section width, a 65-series profile, and fitment for a 17-inch wheel. For the 2006 Dodge Magnum, this size belongs to 17-inch applications and represents a different wheel-and-tire package than the 18-inch and 20-inch setups used elsewhere in the range. The practical decision here is making sure the car actually has the correct 17-inch wheel before moving into product selection. This size matters most for buyers keeping a Magnum in its standard-style trim configuration rather than moving toward larger-diameter wheel fitment.
245/45R20 is a metric radial size where 245 gives the section width in millimeters, 45 is the aspect ratio, and 20 is the rim diameter in inches. On the 2006 Dodge Magnum, this size is tied to the 20-inch SRT8 front fitment and is part of the model's more aggressive performance-oriented setup. Available choices in this size include BFGoodrich, Nitto, and Pro-Trac, with Blackwall, Redline, and RWL sidewall treatments across series such as g-Force and Street Pro III. It is the size to evaluate when the Magnum has the correct 20-inch front wheel and the buyer wants either a conventional modern look or a more custom muscle-era appearance.
255/45R20 is a metric radial size with a wider 255-millimeter section width, a 45-series profile, and a 20-inch wheel diameter. On the 2006 Dodge Magnum, this size serves the SRT8 rear position and works as the back half of the staggered 20-inch setup rather than a universal fitment across all trims. Product choices include BFGoodrich, Nitto, and Pro-Trac, with Blackwall, Redline, and RWL sidewall styles available depending on the series. This size should be chosen only after confirming rear-wheel application and making sure the wider rear tire matches the wheel width and overall stance of the car.
Tire fitment on the 2006 Dodge Magnum varies by sub-model, and the wheel diameter changes with it. Checking the exact trim matters because the Magnum range spans 17-inch, 18-inch, and 20-inch applications, with the SRT8 also introducing a staggered front-and-rear setup.

2006 Dodge Magnum R/T (AWD)
The 2006 Dodge Magnum R/T (AWD) uses the 225/60R18 radial size. Tire selection here is mainly about confirming the 18-inch wheel package and then choosing a tire that matches the car's intended mix of road use, appearance, and overall setup.
The 2006 Dodge Magnum R/T (RWD) also uses the 225/60R18 radial size. That keeps fitment straightforward, but the buyer should still verify that the car has not been changed to a different wheel diameter before selecting tires.
The 2006 Dodge Magnum SE uses the 215/65R17 radial size on a 17-inch wheel package. The practical priority is keeping the correct wheel diameter in place and matching the tire choice to the car's present ride height, wheel setup, and intended use.
The 2006 Dodge Magnum SRT8 uses 20-inch radial fitment, and its tire selection should be approached as a performance-oriented setup rather than a one-size-fits-all Magnum application. Wheel position matters here, especially if the car is still using its staggered arrangement or has been changed from stock.
The 2006 Dodge Magnum SRT8 Front uses 245/45R20. That means front tire choice should be made with the correct 20-inch front wheel in mind, along with any preference for Blackwall, Redline, or RWL presentation where available.
The 2006 Dodge Magnum SRT8 Rear uses 255/45R20. Because this is the wider rear portion of the staggered setup, the buyer should confirm rear wheel width and keep front-versus-rear positioning straight before comparing tire options.
The 2006 Dodge Magnum SXT (AWD) uses the 225/60R18 radial size. Tire choice begins with confirming that the vehicle is still on the proper 18-inch wheel package, then narrowing the selection based on present-day driving needs and fitment condition.
The 2006 Dodge Magnum SXT (RWD) can use either 215/65R17 or 225/60R18, so wheel diameter must be verified before selecting a tire. This trim is a good example of why checking the actual wheel on the car matters more than relying on the model name alone.
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 Dodge Magnum?
The 2006 Dodge Magnum uses several tire sizes rather than one universal fitment. Depending on sub-model, the primary sizes are 215/65R17, 225/60R18, 245/45R20, and 255/45R20, and all are radial tires. The SRT8 setup is especially important because it uses 20-inch sizing and can involve different front and rear tire sizes.
The right way to choose is to identify the exact trim and then confirm the wheel diameter actually on the car. A Magnum that has been fitted with different wheels over the years may no longer match its original trim-based sizing, so checking the sidewall of the existing tire and measuring the wheel is a smart first step.
What size rim does a 2006 Dodge Magnum use?
A 2006 Dodge Magnum can use 17-inch, 18-inch, or 20-inch rims, depending on sub-model and tire size. The 215/65R17 fitment uses a 17-inch rim, 225/60R18 uses an 18-inch rim, and the SRT8-related 245/45R20 and 255/45R20 sizes use 20-inch rims.
Wheel diameter is the first fitment detail to verify because the tire size must match it exactly. A 17-inch tire cannot be mounted on an 18-inch wheel, and a 20-inch SRT8 tire setup should not be assumed for every Magnum, especially if the vehicle has seen aftermarket wheel changes or trim conversions.
Why does the 2006 Dodge Magnum have more than one tire size?
The 2006 Dodge Magnum was offered in several sub-models, and they did not all use the same wheel-and-tire package. SE, R/T, SXT, and SRT8 applications vary, with some using 17-inch or 18-inch fitment and the SRT8 using 20-inch sizing, including a staggered front-and-rear arrangement.
That variation means the model name by itself is not enough for accurate tire selection. The practical choice starts with confirming the exact trim and then checking whether the wheels on the car are still original to that setup, since many Magnums have been customized with different wheel diameters or replacement packages over time.
Choosing the Right Tire
What should I consider when choosing a 245/45R20 or 255/45R20 tire for a 2006 Dodge Magnum?
Start by confirming whether the car uses the SRT8 20-inch setup and whether the tire is for the front 245/45R20 position or the rear 255/45R20 position. These are not interchangeable just because they share the same wheel diameter. Brand, tire series, sidewall style, and stated rim-width specifications can all affect which option best suits the car.
A buyer comparing 20-inch Magnum tires should also look at how the vehicle is used and how much emphasis goes to appearance. Redline and RWL choices create a much different presentation than Blackwall, while wheel width and rear-versus-front placement matter before committing to a tire in the wider SRT8-style sizes.
What sidewall styles are available for 2006 Dodge Magnum tires?
In the available 20-inch Magnum sizes, sidewall choices include Blackwall, Redline, and RWL. Blackwall appears across BFGoodrich and Nitto offerings, while Pro-Trac Street Pro III adds Redline and RWL versions in both 245/45R20 and 255/45R20.
That sidewall choice changes the visual character of the car even when the tire size stays the same. Blackwall keeps a more contemporary look, while Redline and raised white letter styling lean more toward a custom or muscle-inspired presentation, so the best choice depends on whether the Magnum is being kept understated or given a more assertive appearance.
What brands offer tires for the 2006 Dodge Magnum?
For the available 20-inch Magnum fitments, tire choices include BFGoodrich, Nitto, and Pro-Trac. Those brands appear across 245/45R20 and 255/45R20 sizing, with series such as g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, Nitto NT555 G2, and Street Pro III.
The practical comparison is less about picking a brand name in isolation and more about matching the actual tire to the car's setup. Sidewall treatment, rim-width suitability, load-related specs where stated, and whether the tire is intended for front or rear SRT8 use all matter as much as the brand on the sidewall.
Restoration & Appearance
Which tire should I choose for a period-style 2006 Dodge Magnum?
A period-style 2006 Dodge Magnum still begins with the correct trim-based size, whether that means 17-inch, 18-inch, or 20-inch fitment. For buyers focused on a more distinctive visual presentation in the 20-inch sizes, Pro-Trac Street Pro III options in Redline or RWL offer a different look than standard Blackwall performance radials.
The key is separating appearance from fitment. A tire can support the style of the build without automatically being historically exact for every Magnum, so owners pursuing a very specific restoration theme should verify trim-era details and wheel setup before choosing a sidewall treatment based mainly on looks.
How does tire construction affect the appearance of a restored 2006 Dodge Magnum?
On the 2006 Dodge Magnum, the primary fitments are radial tires, so the construction question is less about bias-ply versus radial and more about how a modern radial is presented. In practice, the visible differences come from sidewall treatment, tread style, and how the tire fills the wheel opening on 17-inch, 18-inch, or 20-inch packages.
That means appearance choices should stay tied to the trim and wheel size actually being used. A Blackwall radial can keep the car looking cleaner and more contemporary, while Redline or RWL choices can push the Magnum toward a more customized performance look without changing the fundamental radial construction the vehicle uses.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2006 Dodge Magnum?
Yes. A 2006 Dodge Magnum may have had aftermarket wheels, lowering components, suspension changes, or brake upgrades, and each of those can affect tire fitment even when the size sounds correct on paper. That is especially important on SRT8-style 20-inch setups, where front and rear sizing already differ from each other.
The safest approach is to confirm wheel diameter and width, then check steering clearance, fender clearance, and rear wheel position with the car at normal ride height. A Magnum that has been altered from stock should always be measured against its actual setup rather than selected only by original trim-based tire sizing.
What should I inspect before driving a 2006 Dodge Magnum on new tires?
Before road use, 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, bead seating, and any visible issues such as cuts, bulges, or irregularity after mounting, especially if the car has been stored or recently revived.
A short, careful test drive is a good next step after installation. Pay attention to rubbing, pulling, vibration, and any sign that the tire is contacting suspension or bodywork, because those symptoms can reveal wheel-width, clearance, or front-versus-rear placement problems that are easy to miss when the car is standing still.
What should I check before a longer drive in a 2006 Dodge Magnum?
Before a longer drive, confirm that the 2006 Dodge Magnum is running the correct tire size for its trim and wheel diameter, and make sure all four tires are in sound condition. Tread condition, sidewall condition, and stable air pressure matter on any vehicle, but they are especially important on a heavier modern wagon with performance-oriented trim levels.
It also helps to recheck clearances after the first miles if the car has 20-inch tires, staggered SRT8 fitment, or any suspension changes. Long trips place more heat and load into the tires, so catching a slow leak, rubbing issue, or mounting problem early can prevent a minor fitment issue from becoming a roadside problem.
