The 2012 Dodge Challenger carried modern muscle-car styling with clear visual links to the original E-body era, but its tire fitment reflects contemporary performance and touring priorities. Depending on the exact sub-model, this Challenger uses 235/55R18, 245/45R20, or 255/45R20 radial tires, so the first step is confirming both the trim and whether the car is on 18-inch or 20-inch wheels. From there, the choice shifts to how the car is used and presented, with blackwall, redline, and raised white letter options available in the 20-inch sizes. Getting the size right matters, especially on cars with staggered SRT8 fitment or wheel changes.
Which Tire Size Is Right for The 2012 Dodge Challenger
Three primary tire sizes apply to the 2012 Dodge Challenger, and the right one depends on the exact sub-model and wheel diameter. Some versions use 18-inch wheels with 235/55R18 tires, while others use 20-inch wheels with either 245/45R20 or, on the SRT8 rear application, 255/45R20. Before choosing a tire, confirm the trim level and check whether the car is set up with 18-inch or 20-inch rims.
A 235/55R18 tire 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 2012 Dodge Challenger, this is a modern radial fitment used on certain sub-models rather than a universal size across the whole range. Its role is straightforward: matching the correct 18-inch wheel setup before any brand or tread-style decision is made. This size should be evaluated carefully on cars that may have been upgraded to 20-inch wheels or altered from their original trim configuration.
Fit(s): R/T, R/T Classic, R/T Plus, R/T w/Super Track Pkg., SRT8, SRT8 Front, and SXT Plus
Construction: Radial|Rim: 20 in
A 245/45R20 tire uses a 245-millimeter nominal section width, a 45-series profile, and an 20-inch rim diameter, placing it squarely in modern performance sizing. For the 2012 Dodge Challenger, it appears across several 20-inch applications, including multiple R/T and SRT8-related configurations. Available choices in this size include BFGoodrich, Nitto, and Pro-Trac, with blackwall, redline, and RWL sidewall treatments plus series such as g-Force and Street Pro III. It is the key size to verify on Challengers equipped with factory-style 20-inch muscle-car wheels.
A 255/45R20 tire is a metric radial size with a 255-millimeter nominal section width, a 45-series profile, and fitment for a 20-inch wheel. On the 2012 Dodge Challenger, this size serves a specific role rather than a full-range one, appearing as the rear fitment for the SRT8 rear application. Product choices include BFGoodrich, Nitto, and Pro-Trac, with blackwall, redline, and RWL sidewall presentations depending on the tire series. This size deserves extra attention on staggered-wheel cars, where front and rear fitment should be confirmed separately.
Tire fitment for the 2012 Dodge Challenger is not the same across every covered sub-model. Checking the exact trim matters because some versions use 18-inch tires, some use 20-inch tires, and the SRT8 rear application uses its own rear size.

2012 Dodge Challenger R/T
The 2012 Dodge Challenger R/T can use either 235/55R18 or 245/45R20 radial tires, depending on the wheel setup on the car. That makes wheel-diameter confirmation the first step before comparing brands, series, or sidewall presentation.
The 2012 Dodge Challenger R/T Classic uses a 245/45R20 radial tire fitment. Tire selection then comes down to choosing among the available 20-inch product styles, including traditional blackwall or more appearance-driven options such as redline and RWL.
The 2012 Dodge Challenger R/T Plus can be fitted with either 235/55R18 or 245/45R20 radial tires. Identifying which wheel package is actually on the car is more important here than comparing tires by brand alone.
The 2012 Dodge Challenger R/T w/Super Track Pkg. uses the 245/45R20 radial size. With the fitment narrowed to one 20-inch size, the main decision becomes selecting the tire series and sidewall style that best suits the car's use and appearance.
The 2012 Dodge Challenger SRT8 uses a 245/45R20 radial tire in this fitment grouping. Buyers should still verify whether they are choosing for a standard front position or pairing tires with the separate SRT8 rear size.
The 2012 Dodge Challenger SRT8 Front uses the 245/45R20 radial size. That front fitment should be matched carefully with the car's rear setup on staggered applications rather than selected as though all four corners use the same size.
The 2012 Dodge Challenger SRT8 Rear uses 255/45R20 radial tires. Rear tire selection should be handled as part of a staggered setup, with attention to matching the proper front size and confirming wheel width before making a final choice.
The 2012 Dodge Challenger SXT uses the 235/55R18 radial size. For this sub-model, the main fitment question is making sure the car remains on the correct 18-inch wheel setup and has not been converted to a different diameter.
The 2012 Dodge Challenger SXT Plus can use either 235/55R18 or 245/45R20 radial tires. The most important step is confirming whether the car is wearing its 18-inch or 20-inch wheels before narrowing the choice to tire style or brand.
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.
Best 2012 Dodge Challenger Tires for Sale
Available 20-inch Challenger tires include BFGoodrich, Nitto, and Pro-Trac options in 245/45R20 and 255/45R20. Buyers can compare blackwall, redline, and RWL sidewall treatments across series such as g-Force, NT555 G2, and Street Pro III, along with rim-width specifications where stated.
The most common 2012 Dodge Challenger tire questions center on exact size by sub-model, 18-inch versus 20-inch wheel fitment, staggered SRT8 setups, and how to choose among available radial tire styles, brands, and sidewall treatments.
Tire Size & Fitment
What tire size fits a 2012 Dodge Challenger?
A 2012 Dodge Challenger can use 235/55R18, 245/45R20, or 255/45R20 tires, depending on the exact sub-model and wheel position. The 255/45R20 fitment is tied to the SRT8 rear application, while 235/55R18 and 245/45R20 appear across other Challenger trims.
The key is not assuming every 2012 Challenger uses the same tire. Start by confirming the trim level, then verify whether the car is on 18-inch or 20-inch wheels and whether it has a staggered front-and-rear setup. That matters even more if the car has been modified or fitted with non-original wheels.
What size rim does a 2012 Dodge Challenger use?
A 2012 Dodge Challenger uses either an 18-inch or 20-inch rim, depending on the specific tire size and sub-model. The 235/55R18 size fits an 18-inch wheel, while both 245/45R20 and 255/45R20 fit 20-inch wheels.
Wheel diameter should be verified before looking at tire brands or sidewall styles. Some Challenger trims can appear similar while using different wheel packages, and SRT8 applications may involve separate front and rear sizes. Checking the actual wheel on the car helps prevent choosing the right tire size for the wrong rim diameter.
Why does the 2012 Dodge Challenger have more than one tire size?
The 2012 Dodge Challenger has more than one tire size because fitment varies by sub-model and wheel package. Some versions use 18-inch wheels with 235/55R18 tires, others use 20-inch wheels with 245/45R20, and the SRT8 rear application uses 255/45R20.
That means tire selection starts with identifying the exact Challenger configuration rather than shopping by year and model alone. A car that has changed wheels since new also needs a visual wheel check. Matching the tire to the actual rim diameter and position on the vehicle is more important than assuming one size covers the entire model line.
Choosing the Right Tire
What should I consider when choosing a 245/45R20 tire for a 2012 Dodge Challenger?
A 245/45R20 tire for a 2012 Dodge Challenger should first match the correct 20-inch application on the car. After size is confirmed, the real comparison points are brand, tire series, sidewall style, and any stated rim-width or load details that suit the wheel and intended use.
This size is available from BFGoodrich, Nitto, and Pro-Trac, with choices that range from blackwall performance-oriented presentations to redline and RWL styles. A buyer focused on appearance may narrow the field differently than one prioritizing a contemporary blackwall look, so the best choice depends on how the Challenger is driven and shown.
What sidewall styles are available for 2012 Dodge Challenger tires?
For the available 20-inch 2012 Dodge Challenger tire options, sidewall styles include blackwall, redline, and RWL. Blackwall appears across BFGoodrich and Nitto choices, while Pro-Trac offers both redline and raised white letter presentations in 245/45R20 and 255/45R20.
Sidewall style changes the car's visual character more than its basic fitment, provided the size remains correct. A blackwall keeps a modern, understated look, while redline or RWL leans harder into muscle-era styling cues. The right choice depends on whether the goal is a cleaner late-model appearance or a stronger retro presentation.
What brands offer tires for the 2012 Dodge Challenger?
Available 20-inch tires for the 2012 Dodge Challenger come from BFGoodrich, Nitto, and Pro-Trac. Those brands cover the 245/45R20 and 255/45R20 fitments with multiple radial series, including g-Force, NT555 G2, and Street Pro III.
Brand alone should not be the only filter. Compare the exact size, confirm the wheel position on staggered cars, and look at sidewall style and any stated rim-width details before deciding. Two tires may share the same nominal size yet appeal to different buyers based on how the Challenger is driven and how period-oriented the finished look should be.
Restoration & Appearance
Which tire should I choose for a period-style 2012 Dodge Challenger?
A period-style 2012 Dodge Challenger tire choice starts with the correct fitted size for the exact sub-model, then moves to the visual character of the tire. On 20-inch applications, options such as redline and RWL sidewalls create a more overt muscle-inspired appearance than a plain blackwall.
The right look depends on whether the car is being kept close to its early-2010s factory-era presentation or styled with a stronger retro theme. Appearance should never come at the expense of proper size and wheel compatibility, especially on SRT8 staggered setups where front and rear fitment may differ.
How does tire construction affect the appearance of a restored 2012 Dodge Challenger?
For the 2012 Dodge Challenger, the primary fitments are radial tires, so construction changes are less about bias-ply versus radial and more about how a modern radial is presented. The biggest visible differences come from sidewall treatment and tire series rather than from a vintage-style construction decision.
That makes details such as blackwall, redline, or raised white letter especially important on a restoration-oriented or show-focused car. Buyers trying to match a specific original-era appearance should also compare the actual wheel package on the vehicle, since an 18-inch SXT setup creates a different visual impression than the 20-inch R/T or SRT8 fitments.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2012 Dodge Challenger?
Modifications can absolutely affect tire fitment on a 2012 Dodge Challenger. Aftermarket wheels, suspension changes, lowering, spacer use, or brake upgrades can alter the space available for the original 235/55R18, 245/45R20, or 255/45R20 sizes, especially on cars with staggered front-and-rear setups.
A Challenger that no longer has its original wheel package should be checked at the wheel itself rather than selected by catalog size alone. Wheel diameter is only part of the picture; width, offset, and clearance at the fender and steering components matter too. That is particularly important when replacing only one axle pair on an SRT8.
What should I inspect before driving a 2012 Dodge Challenger on new tires?
Before driving a 2012 Dodge Challenger on new tires, inspect the wheels for the correct diameter and condition, confirm proper inflation, and look over the suspension and alignment-related wear points. It also helps to verify that the tire size matches the actual trim and wheel position on the car.
A short clearance check at full steering lock is worthwhile on 20-inch cars and on any Challenger with aftermarket wheels. After the first miles, recheck air pressure and watch for any rubbing, vibration, or uneven contact. Those simple steps help confirm that the tires are seated, sized, and operating as intended.
How often should tires on a 2012 Dodge Challenger be inspected?
Tires on a 2012 Dodge Challenger should be inspected regularly, especially if the car is driven seasonally or stored for long periods. Look for tread wear, cracking, bulges, punctures, and pressure loss, and check both front and rear sizes carefully on staggered SRT8 applications.
Collector-minded or low-mileage use can hide tire aging because the tread may still look fresh while the rubber is getting older. A visual inspection before routine drives and a more thorough check before longer trips helps catch issues early. Cars that sit should also be monitored for flat spotting and pressure change during storage.
