The 2007 Dodge Magnum brought full-size American wagon utility into the modern Hemi era, blending rear-wheel-drive muscle-car character with a long-roof body that still stands apart today. Buyers looking at one now are often balancing daily-road manners, performance attitude, and a presentation that suits the specific trim. Tire fitment on the 2007 Dodge Magnum is entirely radial, but size choice varies by sub-model, from 17-inch and 18-inch applications to staggered 20-inch SRT8 fitments. That opens up meaningful differences in sidewall style, tire series, and brand selection, especially on the 20-inch sizes. The right choice starts with the exact trim and wheel setup already on the car.
Which Tire Size Is Right for The 2007 Dodge Magnum
The 2007 Dodge Magnum 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, with the SRT8 using 20-inch sizing and a staggered front-to-rear setup. Before choosing a tire, confirm the trim level and verify the wheel diameter currently on the car, especially if it has been changed from stock-style sizing.
Fit(s): R/T (AWD), R/T (RWD), SXT (AWD), and SXT (RWD)
Construction: Radial|Rim: 18 in
A 225/60R18 tire is a metric radial size with a 225-millimeter nominal section width, a 60-series aspect ratio, and fitment for an 18-inch rim. On the 2007 Dodge Magnum, this size serves several AWD and RWD configurations, making it one of the key fitments in the range. Its overall proportions suit owners who need to stay with the correct 18-inch application rather than moving up or down in wheel diameter. Choosing this size starts with confirming that the car is one of the Magnum trims equipped for 18-inch radial fitment.
A 215/65R17 tire uses a 215-millimeter nominal section width, a 65-series profile, and an open R that identifies radial construction on a 17-inch rim. This size appears on the 2007 Dodge Magnum in SE trim and in certain SXT applications, so it is tied to specific configurations rather than the entire model line. The slightly taller-profile format gives this fitment a distinct place within the Magnum lineup compared with the 18-inch and 20-inch options. It is the right size to evaluate only after confirming that the car actually carries the 17-inch wheel setup.
A 245/45R20 tire is a metric radial size with a 245-millimeter nominal width, a 45-series profile, and a 20-inch rim diameter. On the 2007 Dodge Magnum, this size is tied to the SRT8 front fitment, so it should be treated as part of a performance-oriented 20-inch setup rather than a general Magnum size. Available choices include BFGoodrich, Nitto, and Pro-Trac options, with Blackwall, Redline, and RWL sidewall treatments across several tire series. Selecting this size means confirming front SRT8 fitment and comparing tire character as well as appearance.
A 255/45R20 tire is a metric radial size that uses a 255-millimeter nominal width, a 45-series profile, and a 20-inch rim. This size is used on the rear of the 2007 Dodge Magnum SRT8, where it works as the wider half of the staggered 20-inch arrangement. Product choices include BFGoodrich, Nitto, and Pro-Trac offerings, with Blackwall, Redline, and RWL sidewall styles depending on the tire series. It should be evaluated as a rear-specific SRT8 fitment, with wheel width and overall front-to-rear setup checked before changing anything.
Tire fitment on the 2007 Dodge Magnum varies meaningfully by sub-model, so trim identification matters before any tire is selected. Wheel diameter changes across the lineup, and the SRT8 adds a staggered 20-inch setup that should not be treated like the rest of the Magnum range.

2007 Dodge Magnum R/T (AWD)
The 2007 Dodge Magnum R/T (AWD) uses the 225/60R18 radial size. Tire selection here is less about choosing between multiple primary sizes and more about staying with the correct 18-inch fitment for the AWD wheel setup already on the car.
The 2007 Dodge Magnum R/T (RWD) also uses 225/60R18 radial tires. That keeps fitment straightforward, but the correct choice still starts with verifying that the car remains on its proper 18-inch wheels and has not been changed to another Magnum wheel package.
The 2007 Dodge Magnum SE uses the 215/65R17 radial size. Buyers should approach this trim as a dedicated 17-inch application and confirm the wheel diameter first, since moving between Magnum trim levels can introduce a completely different fitment.
The 2007 Dodge Magnum SRT8 uses 20-inch radial sizing, with 245/45R20 at the front and 255/45R20 at the rear. Tire choice here centers on preserving the staggered layout and comparing available series and sidewall treatments without mixing up front and rear positions.
The 2007 Dodge Magnum SRT8 Front position uses the 245/45R20 radial size. That makes front tire selection a matter of matching the proper 20-inch front fitment while considering whether Blackwall, Redline, or RWL better suits the car's presentation.
The 2007 Dodge Magnum SRT8 Rear position uses the 255/45R20 radial size. Keeping the rear-specific size in place matters on a staggered setup, so wheel width and rear clearance should be part of the selection process before changing tire series or sidewall style.
The 2007 Dodge Magnum SXT (AWD) uses the 225/60R18 radial size. This fitment aligns the car with the 18-inch Magnum applications, so the main priority is confirming the existing wheel setup rather than comparing across unrelated trim-level sizes.
The 2007 Dodge Magnum SXT (RWD) can use either 215/65R17 or 225/60R18, depending on the wheel package on the car. Tire choice begins with confirming whether the Magnum is on 17-inch or 18-inch wheels, since both sizes belong to this sub-model but are not interchangeable without the matching rim diameter.
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 questions on a 2007 Dodge Magnum usually come down to trim-specific sizing, wheel diameter, and whether the car uses a standard or staggered setup. The answers below focus on fitment, product selection, appearance choices, and the checks worth making before putting the car back on the road.
Tire Size & Fitment
What tire size fits a 2007 Dodge Magnum?
A 2007 Dodge Magnum can use 215/65R17, 225/60R18, 245/45R20, or 255/45R20, depending on the sub-model and wheel position. SE uses 215/65R17, several R/T and AWD applications use 225/60R18, and the SRT8 uses 245/45R20 in front with 255/45R20 in the rear.
The first step is identifying the exact trim and confirming the wheel diameter already on the car. An SXT (RWD) may use either 17-inch or 18-inch fitment, while the SRT8 should be treated as a staggered front-and-rear 20-inch setup rather than a single-size application.
What size rim does a 2007 Dodge Magnum use?
The 2007 Dodge Magnum uses 17-inch, 18-inch, or 20-inch rims depending on the sub-model. The 215/65R17 size fits a 17-inch rim, 225/60R18 fits an 18-inch rim, and both 245/45R20 and 255/45R20 fit 20-inch rims.
Rim diameter should be verified before looking at tread style or brand because the correct tire size follows the wheel on the car. That matters most on SXT (RWD) models, which can appear with either 17-inch or 18-inch fitment, and on SRT8 cars that use 20-inch wheels front and rear.
Why does the 2007 Dodge Magnum have more than one tire size?
The 2007 Dodge Magnum has more than one tire size because tire fitment changes with trim level, drivetrain, and in one case front-versus-rear position. SE, R/T, SXT, and SRT8 versions do not all share the same wheel package, so the tire size changes with the configuration.
That means the correct choice is not based on the Magnum name alone. A buyer should confirm the exact sub-model, check whether the car has 17-inch, 18-inch, or 20-inch wheels, and on an SRT8 make sure the front and rear sizes are not being confused or combined incorrectly.
Choosing the Right Tire
What should I consider when choosing a 245/45R20 or 255/45R20 tire for a 2007 Dodge Magnum?
Start by confirming whether the tire is for the front or rear of a 2007 Dodge Magnum SRT8. The front uses 245/45R20 and the rear uses 255/45R20, so choosing the right size is the first decision before comparing brands, tire series, sidewall treatment, or rim-width specification.
Once size is confirmed, compare the available options by how the car will be used and how you want it to look. Blackwall choices keep a modern presentation, while Redline and RWL add more visual character. Wheel width should also be checked against the tire specification before changing from one product line to another.
What sidewall styles are available for 2007 Dodge Magnum tires?
For the 20-inch 2007 Dodge Magnum fitments, available sidewall styles include Blackwall, Redline, and RWL. Those choices appear in 245/45R20 and 255/45R20 sizes, giving SRT8 owners room to shape the car's presentation while staying within the correct radial size range.
A sidewall change affects appearance more than basic fitment, but it still belongs after the correct size and wheel setup have been confirmed. Redline and RWL can push the car toward a more distinctive visual style, while Blackwall keeps the look closer to a modern performance-tire presentation.
What brands offer tires for the 2007 Dodge Magnum?
The 20-inch tire sizes used on the 2007 Dodge Magnum SRT8 are available from BFGoodrich, Nitto, and Pro-Trac. Those choices cover several tire series, including g-Force lines, Nitto NT555 G2, and Pro-Trac Street Pro III, with different sidewall treatments across the range.
Brand choice should come after confirming the exact Magnum fitment and wheel position. Once the proper size is established, compare each option by sidewall style, tire series, and wheel-width compatibility rather than assuming every product in a nearby size serves the same role on the car.
Restoration & Appearance
Which tire should I choose for a period-style 2007 Dodge Magnum?
A period-style 2007 Dodge Magnum tire choice starts with the correct trim-specific size, then moves to the overall look you want from the car. On 20-inch SRT8 fitments, Pro-Trac Street Pro III options with Redline or RWL sidewalls offer a more expressive appearance than a standard Blackwall tire.
The right visual direction depends on whether the goal is a clean modern-driver look or something that leans harder into the Magnum's muscle-wagon personality. Keep the size and wheel position correct first, then use sidewall treatment and tire series to shape the presentation without compromising basic fitment.
How does tire construction affect the appearance of a restored 2007 Dodge Magnum?
On a 2007 Dodge Magnum, construction does not create a bias-ply-versus-radial appearance decision because the primary fitments are radial. The visual differences come more from size, profile, and sidewall treatment, especially on SRT8 applications where Blackwall, Redline, and RWL choices are available.
That makes tire selection more about matching the car's era and intended style than recreating an earlier construction type. A Magnum being refreshed as a clean late-2000s performance wagon may suit one presentation, while a more personalized build may benefit from a stronger sidewall statement within the proper size.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2007 Dodge Magnum?
Yes. Modifications can affect tire fitment on a 2007 Dodge Magnum even when the tire size itself is correct for the original trim. Aftermarket wheels, changes in wheel width or offset, lowered suspension, and body alterations can all change how much clearance the tire has during steering and suspension movement.
A Magnum with changed wheels should be checked carefully before new tires are chosen. Verify the actual rim diameter on the car, compare wheel width to the tire's approved range where available, and inspect front and rear clearance separately on an SRT8 because its fitment is staggered.
What should I inspect before driving a 2007 Dodge Magnum on new tires?
Before driving a 2007 Dodge Magnum on new tires, inspect the wheels for the correct diameter and condition, make sure the tire size matches the trim, and confirm proper air pressure. It is also wise to look over suspension and steering components so the new tires are not being asked to work around worn hardware.
A short clearance check can prevent avoidable problems, especially if the car has aftermarket wheels or has sat for a long period. Watch for rubbing at full steering lock, uneven stance, vibration, and any sign of contact at the fender or inner wheelhouse once the car is back on the road.
What should I check before a longer drive in a 2007 Dodge Magnum?
Before a longer drive, check tread condition, sidewalls, air pressure, and signs of air loss on the 2007 Dodge Magnum's tires. A car that is driven occasionally should also be inspected for age-related cracking, cuts, bulges, or uneven wear that may not be obvious during short local use.
Longer trips put more heat and sustained load into the tires, so the correct front and rear placement matters just as much as the size itself. That is especially important on an SRT8, where the 245/45R20 front and 255/45R20 rear arrangement should remain in the proper positions.
