The 2011 Dodge Challenger brought modern muscle-car proportions into a distinctly retro shape, blending everyday drivability with styling that nodded directly to the original Challenger era. That combination makes tire choice especially important, because stance and sidewall presentation affect the car’s look almost as much as its road manners. This model uses radial tire fitments in 235/55R18, 245/45R20, and 255/45R20 depending on the sub-model and wheel position. Available choices include blackwall, redline, and raised white letter styles across several performance-oriented series. The key is matching the exact sub-model and wheel setup before comparing appearance and tire-character differences.
Which Tire Size Is Right for The 2011 Dodge Challenger
Three tire sizes apply to the 2011 Dodge Challenger, and the right one depends on the exact sub-model and whether the car uses 18-inch or 20-inch wheels. Some versions share the same size all around, while SRT8 fitment can split front and rear sizes. Before choosing a tire, confirm the specific Challenger trim and actual wheel diameter on the car, especially if it has been changed from stock-style fitment.
In 235/55R18, the 235 is the section width in millimeters, 55 is the aspect ratio, R identifies radial construction, and 18 is the rim diameter in inches. This is a modern radial size used on 18-inch-wheel Challenger applications, giving the car a taller sidewall profile than the 20-inch fitments. Product choices are not shown here for this size, so the main consideration is confirming that the vehicle actually uses the 18-inch setup. It is the right place to start for SE-based applications and any Challenger that still carries its original-style 18-inch wheel package.
Fit(s): R/T, R/T Classic, R/T Plus, R/T w/Super Track Pkg., SE w/Super Sport Pkg., SRT8, and SRT8 Front
Construction: Radial|Rim: 20 in
In 245/45R20, the tire is 245 millimeters wide, the sidewall height is based on a 45-series profile, and the tire mounts on a 20-inch rim. This radial size appears across many 20-inch Challenger applications, including several R/T and SRT8-related fitments, so it is one of the most common choices for this model year. Available options include BFGoodrich, Nitto, and Pro-Trac products in blackwall, redline, and raised white letter styles, with series such as g-Force and Street Pro III. It is the size to evaluate when the car has 20-inch wheels and a square front-to-rear setup.
In 255/45R20, the 255 indicates a wider section width than 245/45R20, while the 45-series profile and 20-inch rim diameter remain the same. This is also a radial fitment, and on the 2011 Challenger it is associated with the SRT8 rear position rather than every version of the car. BFGoodrich, Nitto, and Pro-Trac options are available, again with blackwall, redline, and raised white letter presentations depending on the tire line. This size matters most when the Challenger uses a staggered setup, so rear-wheel confirmation is essential before selecting a replacement.
Tire fitment on the 2011 Dodge Challenger varies by sub-model, and in some cases by wheel position as well. Checking the exact trim matters because this model year includes both 18-inch and 20-inch applications, plus an SRT8 rear size that differs from the front.

2011 Dodge Challenger R/T
The 2011 Dodge Challenger R/T can use either 235/55R18 or 245/45R20 depending on the wheel package. Tire selection starts with confirming whether the car is on 18-inch or 20-inch wheels, then narrowing the choice by sidewall style and tire series.
The 2011 Dodge Challenger R/T Classic uses the 245/45R20 radial size. That makes the decision more about comparing the available 20-inch tire options, including blackwall, redline, and raised white letter styles, rather than sorting through multiple primary sizes.
The 2011 Dodge Challenger R/T Plus uses 245/45R20. With the size already narrowed down, the practical next step is choosing among the available radial tire lines and sidewall presentations that best suit the car’s intended look and use.
The 2011 Dodge Challenger R/T w/Super Track Pkg. uses 245/45R20. Since the fitment stays within one 20-inch radial size, selection focuses on product character, sidewall appearance, and making sure the wheel setup has not been altered.
The 2011 Dodge Challenger SE uses 235/55R18. For this sub-model, the first priority is staying with the correct 18-inch fitment and then checking that the wheel package on the car still matches the original-style size.
The 2011 Dodge Challenger SE Rallye uses 235/55R18. That keeps fitment straightforward, but it is still worth confirming the actual wheel diameter before purchase because later owner changes can move the car away from its original-size setup.
The 2011 Dodge Challenger SE w/Super Sport Pkg. uses 245/45R20. Once that 20-inch size is confirmed, the main decision becomes choosing the tire line and sidewall treatment that fits the car’s appearance and road-use goals.
The 2011 Dodge Challenger SRT8 uses 245/45R20 as a primary fitment, with separate front and rear fitments also broken out elsewhere. Tire replacement on an SRT8 should begin with confirming whether the car is being matched as a square setup or by axle position.
The 2011 Dodge Challenger SRT8 Front uses 245/45R20. Front tire selection should stay focused on that size while also checking that the wheel and staggered setup, if present, remain consistent with the rest of the car.
The 2011 Dodge Challenger SRT8 Rear uses 255/45R20. That rear-specific size makes it especially important to confirm axle position before ordering, since a staggered Challenger should not be treated like a same-size setup at all four corners.
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.

Owners of a 2011 Dodge Challenger usually need to sort out exact tire size by trim, wheel diameter, and in some cases front-versus-rear fitment. The questions below focus on size selection, available tire styles, product differences, and practical checks before road use.
Tire Size & Fitment
What tire size fits a 2011 Dodge Challenger?
The 2011 Dodge Challenger uses three radial tire sizes: 235/55R18, 245/45R20, and 255/45R20. Which one applies depends on the sub-model and wheel setup. Many 20-inch applications use 245/45R20, while 235/55R18 appears on certain 18-inch setups, and 255/45R20 is used at the rear on the SRT8 Rear fitment.
The practical first step is identifying the exact Challenger trim and confirming the actual wheels on the car. An R/T can be found with either 18-inch or 20-inch fitment, and an SRT8 may involve separate front and rear sizes, so replacement should begin with the vehicle’s current wheel and axle configuration.
What size rim does a 2011 Dodge Challenger use?
A 2011 Dodge Challenger uses either an 18-inch or 20-inch rim, depending on the tire size and sub-model. The 235/55R18 fitment mounts on an 18-inch rim, while both 245/45R20 and 255/45R20 use 20-inch rims. That makes wheel diameter one of the most important checks before selecting replacement tires.
Tire size and rim diameter have to match, so a 20-inch tire cannot be used on an 18-inch wheel, and the reverse is also true. The safest approach is to read the size on the current tire and confirm the wheel itself, especially on a Challenger that may have been upgraded to aftermarket wheels.
Why does the 2011 Dodge Challenger have more than one tire size?
More than one tire size appears on the 2011 Dodge Challenger because the model line includes different trims, wheel packages, and at least one staggered application. SE-based versions can use 235/55R18, many R/T and SRT8-related applications use 245/45R20, and the SRT8 Rear fitment uses 255/45R20.
That variation means tire selection should not be based on the model name alone. The buyer needs to confirm the exact sub-model, check whether the car has 18-inch or 20-inch wheels, and note whether the front and rear use the same size before comparing brands, series, or sidewall styles.
Choosing the Right Tire
What should I consider when choosing a 245/45R20 tire for a 2011 Dodge Challenger?
A 245/45R20 tire for a 2011 Dodge Challenger should first match the correct sub-model and wheel package, then be compared by tire series, sidewall style, and rim-width specification. This size is available from BFGoodrich, Nitto, and Pro-Trac, with choices that include blackwall, redline, and raised white letter presentations.
After the size is confirmed, think about how the car will be used and how you want it to look. A Challenger kept close to a modern factory-inspired appearance may lean toward blackwall, while a more nostalgic muscle-car presentation may point toward redline or raised white letter styling on the correct 20-inch wheel.
What sidewall styles are available for 2011 Dodge Challenger tires?
For the 20-inch Challenger fitments shown here, available sidewall styles include blackwall, redline, and RWL, which means raised white letter. Those choices appear within both 245/45R20 and 255/45R20, giving the 2011 Dodge Challenger owner a meaningful appearance decision even after the correct tire size has been identified.
Sidewall style changes the car’s presentation more than many buyers expect. Blackwall keeps a cleaner modern look, while redline and raised white letter options push the car toward a more overt muscle-car visual character, so the best choice depends on whether the goal is subtle road use or a stronger retro-inspired stance.
What brands offer tires for the 2011 Dodge Challenger?
BFGoodrich, Nitto, and Pro-Trac offer tires in the 20-inch sizes used on the 2011 Dodge Challenger. Within those sizes, the available series include BFGoodrich g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, Nitto NT555 G2, and Pro-Trac Street Pro III.
Brand choice should come after size and wheel fitment are confirmed. Once the correct 245/45R20 or 255/45R20 application is established, compare series character, sidewall appearance, and any rim-width requirements so the tire choice matches both the Challenger’s setup and the owner’s visual preference.
Restoration & Appearance
Which tire should I choose for a period-style 2011 Dodge Challenger?
A period-style 2011 Dodge Challenger tire choice starts with the correct fitment for the specific trim, then moves to appearance. For many 20-inch applications, the available choices include blackwall, redline, and raised white letter options, which means the car can be kept understated or given a more overt muscle-car visual theme.
The best approach is to decide whether the goal is a cleaner modern look or a stronger retro-inspired presentation. Size accuracy still comes first, and buyers pursuing a highly exact restoration-style result should compare the car’s current presentation with marque references, original sales material, or trusted Challenger-specific historical guidance.
How does tire construction affect the appearance of a restored 2011 Dodge Challenger?
On a 2011 Dodge Challenger, the primary fitments are radial, so the biggest appearance differences come from sidewall treatment rather than switching between bias-ply and radial construction. In the 20-inch sizes, blackwall, redline, and raised white letter choices create noticeably different visual personalities while staying within radial construction.
That matters on a restoration-oriented or show-focused car because the sidewall can either emphasize the Challenger’s modern muscle identity or pull it toward a more retro cue. Matching the tire size to the exact trim remains essential, but once that is settled, sidewall style becomes one of the strongest appearance decisions available.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2011 Dodge Challenger?
Yes, modifications can affect tire fitment on a 2011 Dodge Challenger even when the size sounds correct on paper. Aftermarket wheels, changes in wheel width, offset differences, suspension lowering, and brake upgrades can all alter how a 235/55R18, 245/45R20, or 255/45R20 tire sits and clears the car.
A Challenger with non-stock wheels should be checked carefully before replacement. Confirm the actual wheel diameter, compare the wheel width to the tire’s fitment range when that information is available, and inspect fender, steering, and suspension clearance so the new tire suits the car’s current setup rather than an assumed one.
What should I inspect before driving a 2011 Dodge Challenger on new tires?
Before driving a 2011 Dodge Challenger on new tires, inspect wheel condition, valve stems, lug hardware, and tire pressure, then make sure the size and mounting position are correct. On cars with staggered fitment, confirm that the rear receives the proper size and that front and rear tires have not been mixed accidentally.
A short, careful road test is a smart follow-up. Listen for rubbing, watch for vibration, and recheck inflation after the first drive, especially if the Challenger has aftermarket wheels or recent suspension work. Those simple checks help catch clearance or installation issues before the car is used at normal highway speeds.
How should tires on a 2011 Dodge Challenger be maintained?
Tires on a 2011 Dodge Challenger should be maintained with regular pressure checks, routine visual inspections, and close attention to tread wear across all four corners. Look for uneven wear, sidewall damage, cuts, bulges, and slow air loss, since any of those conditions can affect how a modern muscle car feels on the road.
Cars that see limited use still need inspection because time, storage conditions, and inactivity can age a tire even when tread looks good. Keeping the Challenger clean, stored away from prolonged sun and ozone sources, and checked before longer drives helps preserve both tire condition and overall road readiness.
