The 2008 Dodge Challenger marked the return of one of Dodge's most recognizable muscle car names, blending retro-inspired styling with modern performance hardware in the SRT8 launch model. Its look deliberately echoed classic Mopar proportions, but its tire fitment is thoroughly contemporary. This application uses staggered 20-inch radial sizing, with 245/45R20 at the front and 255/45R20 at the rear, so the first step is confirming where the tire will be mounted. Available choices include blackwall, redline, and raised white letter sidewall treatments across several performance-oriented series. For owners balancing appearance, road manners, and correct front-to-rear fitment, construction and position matter more than nostalgia alone.
Which Tire Size Is Right for The 2008 Dodge Challenger
The 2008 Dodge Challenger uses two primary tire sizes, and the difference is tied to position rather than unrelated trim levels. Both are radial tires for 20-inch wheels, but the front and rear SRT8 fitments are not the same, so identifying whether you need a front, rear, or all-season SRT8 replacement is the key first step before comparing brands, sidewall styles, or tire series.
245/45R20 is a modern metric radial size in which 245 identifies nominal section width in millimeters, 45 is the aspect ratio, R denotes radial construction, and 20 is the wheel diameter in inches. On the 2008 Dodge Challenger, this size is used in the SRT8 front position and also appears in the SRT8 all-season listing. Available choices include BFGoodrich, Nitto, and Pro-Trac options with blackwall, redline, and RWL sidewall treatments across series such as g-Force and Street Pro III. This is the size to evaluate when replacing front-position tires while keeping the intended 20-inch setup.
255/45R20 follows the same metric radial sizing format, with a wider nominal section width than 245/45R20 while keeping the same 45-series profile family and 20-inch rim diameter. On the 2008 Dodge Challenger, this size serves the SRT8 rear position, making it part of the car's staggered fitment rather than a universal all-around size. Product choices include BFGoodrich, Nitto, and Pro-Trac offerings, again with blackwall, redline, and RWL appearance options in several performance-focused series. This is the size to compare when rear traction, stance, and correct rear-wheel compatibility are the immediate concern.
Sub-model fitment on the 2008 Dodge Challenger is straightforward once the exact SRT8 application is identified, but front and rear positions do not use the same tire size. Checking the specific sub-model or axle position matters because the 20-inch wheel diameter stays the same while the tire width changes.

2008 Dodge Challenger SRT8 (All-Season Tire)
The 2008 Dodge Challenger SRT8 all-season application uses a 245/45R20 radial tire. That keeps selection focused on choosing the right 20-inch radial within that size, including brand, series, and sidewall presentation rather than sorting through multiple primary fitments.
The 2008 Dodge Challenger SRT8 front position uses 245/45R20 radial tires. Front replacement means confirming that the tire matches the intended axle position, then comparing options such as blackwall, redline, or RWL styling within the available performance-oriented product range.
The 2008 Dodge Challenger SRT8 rear position uses 255/45R20 radial tires. Rear tire selection should center on maintaining the correct staggered setup, confirming wheel compatibility, and choosing among the available brand and sidewall options in that wider rear 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.

Tire Size & Fitment
What tire size fits a 2008 Dodge Challenger?
The 2008 Dodge Challenger uses two radial tire sizes: 245/45R20 and 255/45R20. On the SRT8 application, 245/45R20 is used at the front, while 255/45R20 is used at the rear, so this is a staggered setup rather than one universal size used at every corner.
That means the first fitment question is not just year and model, but also tire position. A front replacement should be matched to the 245/45R20 fitment, and a rear replacement should be matched to 255/45R20, while any modified wheel or suspension setup deserves an extra clearance and wheel-width check before installation.
What size rim does a 2008 Dodge Challenger use?
The 2008 Dodge Challenger fitments covered here use 20-inch rims. Both primary tire sizes, 245/45R20 and 255/45R20, are built for the same 20-inch wheel diameter even though the front and rear tire widths differ.
Rim diameter should still be confirmed on the actual car before replacement, especially if the Challenger has been changed from its original wheel package. The tire size must match the wheel diameter exactly, and wheel width also matters when comparing products because the 245 and 255 sizes do not share the same ideal width range.
Why does the 2008 Dodge Challenger have more than one tire size?
The 2008 Dodge Challenger uses more than one tire size because the SRT8 fitment is staggered, with a narrower 245/45R20 tire at the front and a wider 255/45R20 tire at the rear. Both remain radial 20-inch tires, but they serve different positions on the car.
That arrangement affects replacement strategy. Owners should confirm whether they are buying for the front axle, rear axle, or a full set, and they should avoid assuming the two sizes are interchangeable simply because they share the same rim diameter and similar profile format.
Choosing the Right Tire
What should I consider when choosing a 245/45R20 or 255/45R20 tire for a 2008 Dodge Challenger?
Start with the correct position-specific size, because the 2008 Dodge Challenger SRT8 uses 245/45R20 at the front and 255/45R20 at the rear. From there, compare radial construction details such as tire series, sidewall style, rim-width suitability, and load figures where they are stated.
Appearance and use both matter on this car. Some owners prefer a straightforward blackwall performance look, while others want redline or raised white letter styling to emphasize the Challenger's muscle-car character, and any final choice should still be checked against the actual wheel setup on the vehicle.
What sidewall styles are available for 2008 Dodge Challenger tires?
The available sidewall styles for the 2008 Dodge Challenger sizes covered here include blackwall, redline, and RWL. Those choices appear within the 245/45R20 and 255/45R20 radial fitments, giving owners a way to keep the same basic size while changing the visual presentation.
Sidewall style does not change the need to match the correct front or rear size, but it can noticeably change the car's overall character. Blackwall keeps the look modern and understated, while redline and raised white letter options bring in a stronger period-inspired muscle-car flavor without changing the 20-inch fitment itself.
What brands offer tires for the 2008 Dodge Challenger?
BFGoodrich, Nitto, and Pro-Trac all offer tires in the 2008 Dodge Challenger fitments covered here. The available choices span several radial series, including BFGoodrich g-Force lines, Nitto NT555 G2, and Pro-Trac Street Pro III options.
Brand choice is best treated as one part of a larger comparison rather than the whole decision. The more useful approach is to start with the correct 245/45R20 front or 255/45R20 rear size, then compare sidewall treatment, rim-width compatibility, and the overall look and intended use you want from the car.
Restoration & Appearance
Which tire should I choose for a period-style 2008 Dodge Challenger?
A period-style 2008 Dodge Challenger tire choice usually starts with keeping the correct staggered 20-inch sizing, then selecting a sidewall treatment that suits the look you want. Blackwall, redline, and RWL options are all available within the covered radial fitments, so appearance can be tailored without abandoning the proper size format.
Because this Challenger is a modern revival of a classic muscle-car name, visual preference often matters as much as raw specification. Owners aiming for a cleaner contemporary look may lean toward blackwall, while redline or raised white letter tires can add a stronger retro accent to the car's already nostalgic styling.
How does tire construction affect the appearance of a restored 2008 Dodge Challenger?
On the 2008 Dodge Challenger fitments covered here, construction itself is not the main appearance dividing line because the primary fitments are radial. The visible difference comes more from sidewall treatment and series character than from choosing between bias-ply and radial, since this application is already rooted in modern radial sizing.
That makes the visual decision more about how aggressive, subtle, or retro you want the car to appear on its 20-inch wheels. A blackwall tire tends to keep the presentation modern, while redline and RWL options can shift the Challenger toward a more overt muscle-car statement without changing its basic fitment layout.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2008 Dodge Challenger?
Yes, modifications can affect tire fitment on a 2008 Dodge Challenger even when the tire sizes themselves are correct. Aftermarket wheels, altered wheel width, suspension changes, lowering, or brake upgrades can all change how a 245/45R20 front or 255/45R20 rear tire sits in the wheel opening.
A modified car should be checked for wheel diameter, wheel width, and clearance at full steering lock and suspension travel before new tires go into service. That is especially important on a staggered setup, where front and rear tires already differ and small changes in wheel specification can have different effects at each axle.
What should I inspect before driving a 2008 Dodge Challenger on new tires?
Before driving a 2008 Dodge Challenger on new tires, inspect that the correct size is mounted in the correct position, verify inflation pressure, and look over the wheels for damage or irregular bead seating. It also helps to confirm there is no rubbing at the front or rear once the car is back on the ground.
A short initial road check is worthwhile after installation. Pay attention to vibration, pulling, unusual noise, or any sign that a front 245/45R20 and rear 255/45R20 set has been mixed incorrectly, and recheck pressure and general condition after the first few miles of normal driving.
What should I check before a longer drive in a 2008 Dodge Challenger?
Before a longer drive in a 2008 Dodge Challenger, check tire pressure, tread condition, sidewall condition, and any sign of cuts, bulges, or uneven wear. The car's staggered sizing also makes it important to confirm that the 245/45R20 front and 255/45R20 rear tires are mounted in their proper positions.
Longer trips put more emphasis on overall condition than occasional local use. It is smart to inspect for slow air loss, confirm that the wheels remain in good condition, and make sure no recent suspension or wheel changes have introduced contact issues that only become obvious after sustained highway driving.
