The 2014 Dodge Challenger carried the long-hood, retro-muscle look of the modern LX-era Mopar while offering a wide spread of trim levels, from V6 cruisers to Hemi-powered performance models. That broad lineup matters when it is time to replace tires, because this Challenger uses three different radial sizes: 235/55R18, 245/45R20, and 255/45R20. Some sub-models share front fitment, while the SRT8 rear uses a wider 255/45R20 on a 20-inch rim. Available choices also vary by brand, tire series, and sidewall style, including blackwall, redline, and raised white letter options. The key is matching the tire to the exact trim and wheel setup before focusing on appearance or performance character.
Which Tire Size Is Right for The 2014 Dodge Challenger
Three tire sizes apply to the 2014 Dodge Challenger, and the right one depends on the exact sub-model and wheel diameter. Both 18-inch and 20-inch rims are used, so confirming the wheel on the car comes first. Some trims can use either 235/55R18 or 245/45R20, while the SRT8 rear uses a separate 255/45R20 fitment that should not be confused with the front size.
235/55R18 is a metric radial size in which 235 identifies the section width in millimeters, 55 is the aspect ratio, R denotes radial construction, and 18 is the rim diameter in inches. On the 2014 Dodge Challenger, this size serves trims that use an 18-inch wheel and gives the car a distinctly different fitment path than the 20-inch setups. Because this page's product assortment centers on the 20-inch sizes, the main value here is confirming whether your Challenger is on the 18-inch wheel package. Check the actual wheel and existing tire size before moving to replacement selection.

Construction: Radial|Rim: 20 in
245/45R20 is a metric radial size with a 245-millimeter section width, a 45-series profile, and a 20-inch rim diameter. It is a core 20-inch Challenger fitment used across several 2014 sub-models, including performance-oriented and appearance-package variants. This size has the broadest product choice here, with options from BFGoodrich, Nitto, and Pro-Trac in blackwall, redline, and RWL sidewall treatments across series such as g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, NT555 G2, and Street Pro III. It is the size to evaluate closely when balancing wheel compatibility, intended use, and the visual character you want.
255/45R20 is a metric radial size in which the 255-millimeter width makes it visibly broader than the 245 front fitment, while the 45-series profile and 20-inch rim keep it within the same general sizing family. On the 2014 Dodge Challenger, this size appears as the SRT8 rear fitment rather than a universal size across the lineup. Available choices include BFGoodrich, Nitto, and Pro-Trac, with blackwall, redline, and RWL presentations depending on the tire series. This size should be chosen only after confirming that the car uses the wider rear wheel and matching that wheel to the tire's intended application.
Sub-model fitment on the 2014 Dodge Challenger is not one-size-fits-all. Some trims use either 18-inch or 20-inch wheel packages, while the SRT8 split front and rear fitment makes the exact sub-model especially important before selecting tires.

2014 Dodge Challenger R/T
The 2014 Dodge Challenger R/T can use either an 18-inch 235/55R18 setup or a 20-inch 245/45R20 setup. That makes wheel confirmation the first step, followed by choosing the tire style and series that match how the car is driven and presented.
The 2014 Dodge Challenger R/T Classic uses the 245/45R20 radial fitment. Tire selection then becomes a matter of comparing available brands, sidewall treatments, and series within that 20-inch size.
The 2014 Dodge Challenger R/T Plus uses 245/45R20 radial tires. With the size established, attention can shift to product character, including blackwall or specialty sidewall styling and the wheel-width range of the tire being considered.
The 2014 Dodge Challenger Rallye Redline uses the 245/45R20 radial size. That keeps the fitment straightforward, but there is still room to tailor the car's look through available sidewall styles and tire series.
The 2014 Dodge Challenger SRT8 uses 245/45R20 in the covered fitment. Selection should stay focused on the correct 20-inch size and on comparing the available radial options that suit the car's wheel setup and intended road use.
The 2014 Dodge Challenger SRT8 Front uses 245/45R20. This matters because the front size should be matched to the actual front wheel, not assumed from the wider rear fitment used elsewhere in the SRT8 setup.
The 2014 Dodge Challenger SRT8 Rear uses the wider 255/45R20 radial size. Rear-tire selection should account for the correct wheel width and should not be mixed up with the narrower 245/45R20 front fitment.
The 2014 Dodge Challenger SXT can use either 235/55R18 or 245/45R20, depending on the wheel package on the car. Verifying the actual rim diameter is more important than assuming fitment from the trim name alone.
The 2014 Dodge Challenger SXT Plus can use either 235/55R18 or 245/45R20. Replacement choice begins with confirming whether the car has the 18-inch or 20-inch setup, then comparing the available radial options in that exact size.
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.

These FAQs focus on 2014 Dodge Challenger tire sizing by trim, 18-inch versus 20-inch wheel fitment, product selection across available radial options, and the checks worth making before putting the car back on the road.
Tire Size & Fitment
What tire size fits a 2014 Dodge Challenger?
The 2014 Dodge Challenger uses three radial tire sizes: 235/55R18, 245/45R20, and 255/45R20. The correct size depends on the exact sub-model and wheel setup. Some trims such as the R/T, SXT, and SXT Plus can use either 18-inch or 20-inch fitments, while the SRT8 rear uses 255/45R20.
That means the first step is confirming the actual tire size already on the car and the wheel diameter it uses. A trim name alone is not always enough, especially on Challengers that could be ordered with different wheel packages or have been changed since new.
What size rim does a 2014 Dodge Challenger use?
A 2014 Dodge Challenger uses either an 18-inch or 20-inch rim, depending on the fitment. The 235/55R18 size is for an 18-inch rim, while both 245/45R20 and 255/45R20 are designed for 20-inch rims. The SRT8 rear fitment uses the wider 255/45R20 on a 20-inch wheel.
Rim diameter needs to be verified before any replacement tire is chosen, because a 20-inch tire will not mount on an 18-inch wheel and vice versa. It is also worth checking wheel width when comparing products, particularly on the wider 20-inch sizes used on performance-oriented setups.
Why does the 2014 Dodge Challenger have more than one tire size?
The 2014 Dodge Challenger has more than one tire size because different sub-models and wheel packages use different fitments. Some trims were equipped with 18-inch wheels and 235/55R18 tires, others use 20-inch wheels with 245/45R20 tires, and the SRT8 rear uses a separate 255/45R20 size.
That variation is normal for a model line that ranges from everyday street trims to more aggressive performance versions. A buyer should identify the exact sub-model and then confirm the actual wheels on the car, since aftermarket changes can make the original trim-based assumption less reliable.
Choosing the Right Tire
What should I consider when choosing a tire for a 2014 Dodge Challenger?
Start with the correct size for the car's exact setup: 235/55R18, 245/45R20, or 255/45R20. From there, compare radial construction details that matter to the way the Challenger is used, including brand, tire series, sidewall style, and wheel-width compatibility where that information is available.
A daily-driven SXT or R/T may lead to a different choice than an SRT8 with a dedicated front and rear arrangement. Matching the tire to the intended use, the actual wheel dimensions, and the appearance you want will narrow the field faster than choosing by brand name alone.
What sidewall styles are available for 2014 Dodge Challenger tires?
The available 20-inch tires for the 2014 Dodge Challenger include blackwall, redline, and RWL sidewall styles. Blackwall options appear across BFGoodrich and Nitto lines, while Pro-Trac Street Pro III options add redline and RWL choices in both 245/45R20 and 255/45R20 sizes.
Sidewall style mainly affects the car's visual presentation rather than the basic fitment. A blackwall keeps the look understated, while redline or raised white letter styling adds more period-inspired muscle-car flavor, so the better choice depends on how closely the car's appearance should lean toward stock-like or custom.
What brands offer tires for the 2014 Dodge Challenger?
The available 20-inch tire options for the 2014 Dodge Challenger include BFGoodrich, Nitto, and Pro-Trac. Within those brands, the product range covers several series such as g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, NT555 G2, and Street Pro III.
Brand choice should be considered alongside the exact size and the character of the tire line itself. Some options stay with a plain blackwall performance look, while others give the Challenger a stronger muscle-car appearance through redline or RWL sidewalls in the same basic size.
Restoration & Appearance
Which tire should I choose for a period-style 2014 Dodge Challenger?
A period-style 2014 Dodge Challenger still needs to start with the correct modern radial size for the sub-model and wheel package. Once that is established, 245/45R20 and 255/45R20 options with redline or RWL sidewalls can give the car a more traditional muscle-car presentation than a plain blackwall tire.
The right appearance choice depends on whether the goal is a restrained showroom-inspired look or a more assertive custom style. Visual preference should come after fitment basics, so confirm the wheel diameter and, on staggered SRT8 setups, make sure the rear tire is not being selected from the front size.
How does tire construction affect the appearance of a restored 2014 Dodge Challenger?
For the 2014 Dodge Challenger, the primary fitments are radial rather than bias-ply, so the main appearance differences come from sidewall treatment and tire series instead of construction type. In practical terms, the visual choice is more about blackwall, redline, or RWL styling within the correct modern radial size.
That gives a restoration-oriented owner some flexibility without moving away from the correct basic construction family for the car. A more subtle build may favor blackwall, while a bolder muscle-era look can lean toward redline or raised white letter styling if it suits the car's overall presentation.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2014 Dodge Challenger?
Yes, modifications can affect tire fitment on a 2014 Dodge Challenger even when the tire size matches a known trim application. Aftermarket wheels, different wheel widths, offset changes, lowering springs, suspension alterations, or brake upgrades can all change how an 18-inch or 20-inch tire sits in the car.
A Challenger with changed wheels should be checked for wheel diameter, wheel width, and clearance at full steering lock and suspension movement before replacement tires are chosen. That matters most when moving between 18-inch and 20-inch packages or when dealing with the wider 255/45R20 rear fitment.
What should I inspect before driving a 2014 Dodge Challenger on new tires?
Before driving a 2014 Dodge Challenger on new tires, inspect the wheels for damage, confirm that the tire size matches the car's actual setup, and make sure inflation is set correctly for the tires being installed. It is also smart to look over alignment condition, lug hardware, and overall tread and sidewall condition on any tire being reused.
A short test drive should include attention to vibration, rubbing, or steering pull, especially if the car has aftermarket wheels or a front and rear staggered setup. Rechecking pressure after the first few drives helps confirm that the tires are settling in properly and holding air as expected.
How should tires on a 2014 Dodge Challenger be maintained?
Tires on a 2014 Dodge Challenger should be maintained through regular pressure checks, visual inspections, and periodic evaluation of tread wear across all four corners. Even on a newer collector-era muscle car, long periods of storage can contribute to air loss, flat spotting, and gradual sidewall aging if the car is not driven often.
Keeping the car on a clean, dry surface and away from prolonged sunlight helps preserve the tires' condition over time. Owners should also watch for uneven wear that may point to alignment or suspension issues, because a powerful rear-drive car can hide fitment or maintenance problems until the tires are already affected.
