2017 Dodge Challenger Tires

The 2017 Dodge Challenger uses four primary tire sizes: 235/55R18, 235/55R19, 245/45R20, and 275/40R20. All of these are radial fitments, but they do not apply across the entire model range. Most trims use 245/45R20, higher-output SRT 392, SRT Hellcat, and T/A 392 models use 275/40R20, the GT uses 235/55R19, and some SXT applications use 235/55R18.

The practical takeaway is that wheel diameter and trim identification matter before choosing a tire. A Challenger wearing 18-inch, 19-inch, or 20-inch wheels will need the matching tire size, and the SXT deserves special attention because it appears with more than one fitment. Checking the door placard, existing tire size, and actual wheel setup helps avoid choosing a tire that is correct for the model year but wrong for the car.

A 2017 Dodge Challenger can use 18-inch, 19-inch, or 20-inch rims depending on the sub-model and tire size. The 235/55R18 fits an 18-inch rim, the 235/55R19 fits a 19-inch rim, and both 245/45R20 and 275/40R20 fit 20-inch rims. Rim diameter is built into the tire size, so the final number in each size is the wheel diameter in inches.

That means a tire cannot be chosen by width alone. A 235/55R18 and 235/55R19 may look similar on paper, but they require different wheels. Owners shopping for replacement tires should verify whether the car still has its original wheel package or has been changed to an aftermarket setup. Diameter comes first, then the proper width and profile can be matched to the exact Challenger trim.

The 2017 Dodge Challenger has more than one tire size because the model range covers several trims with different wheel packages and performance intent. Some versions use 18-inch or 19-inch fitments, while many 20-inch cars use 245/45R20 and higher-output configurations move to the wider 275/40R20. The SXT also appears with more than one primary fitment, depending on how the car was equipped.

That variation is why trim level alone is helpful but not always enough. The safest approach is to confirm both the sub-model and the wheels actually on the car before comparing tires. A Challenger that has been upgraded, swapped to different factory-style wheels, or fitted with aftermarket rims may no longer match the size another trim from the same year uses.

Start with the fact that 245/45R20 is a common 20-inch radial fitment for many 2017 Dodge Challenger trims. Within that size, available choices include BFGoodrich, Nitto, and Pro-Trac products, with blackwall, redline, and RWL sidewall treatments represented. Tire series also vary, so the decision is not just about size but about the kind of look and driving character you want from the car.

Rim compatibility is worth checking as well, especially if the car no longer has its original wheels. Some 245/45R20 products include rim-width guidance in the 7.5- to 9-inch range, which can help narrow the field. Matching the tire to the wheel, intended road use, and visual style will usually do more for satisfaction than simply choosing the first tire that shares the right size.

Sidewall style depends on the tire size and product chosen, but the available 2017 Dodge Challenger options include blackwall, redline, and RWL. In the 245/45R20 and 275/40R20 sizes, blackwall tires appear alongside Pro-Trac Street Pro III versions with redline or raised white letter styling. That gives owners both understated and more appearance-driven choices within the correct fitment.

The right sidewall comes down to how the Challenger is used and how closely the owner wants the tire to shape the car's personality. A blackwall keeps the presentation cleaner and more modern, while redline or RWL can emphasize the car's retro muscle theme. Sidewall style should be treated as an appearance decision after the correct size, rim diameter, and intended use have already been confirmed.

Available brands for the 2017 Dodge Challenger include BFGoodrich, Nitto, Pro-Trac, and M&H Racemaster, depending on tire size. The 245/45R20 size is offered by BFGoodrich, Nitto, and Pro-Trac, while 275/40R20 also adds an M&H Racemaster option. Brand choice in this case is tied to size, tire series, and sidewall style rather than a single one-brand-fits-all answer.

The best way to use that brand variety is to compare products within the exact size your Challenger requires. One tire may offer a different sidewall treatment, another may suit a narrower or wider rim range, and another may be aimed at a more specialized use. Comparing those details within the correct fitment will tell you more than choosing only by brand name.

A period-style 2017 Dodge Challenger tire choice starts with the exact size the car uses, then moves to the sidewall and tire series that best support its retro muscle presentation. For 20-inch applications, 245/45R20 and 275/40R20 are available in blackwall as well as styled options such as redline and RWL. That makes it possible to keep the fitment modern while leaning harder into the Challenger's throwback visual theme.

Appearance goals should still come after correct fitment. Confirm the trim, wheel diameter, and actual wheel setup before selecting a more style-driven tire, especially on cars that may have been changed from their original wheel package. For owners seeking a highly exact presentation, marque-specific references and original vehicle documentation remain the better guide for visual authenticity than size alone.

On the 2017 Dodge Challenger, the primary fitments are radial tires, so the construction itself is not the visual fork in the road that it is on older collector vehicles. The more visible difference comes from the tire's profile, series, and sidewall treatment. In the available 20-inch sizes, that can mean choosing between a plain blackwall look and more expressive redline or raised white letter styling.

That distinction matters because a Challenger's personality can change noticeably with the sidewall alone, even when the size stays the same. Owners building a cleaner late-model muscle look may prefer blackwall, while a more overt retro treatment can push the car closer to classic street-machine territory. The right answer depends on the car's existing wheel package and the kind of finished presentation the owner wants.

Yes, modifications can affect tire fitment on a 2017 Dodge Challenger even when the tire size itself is correct for a factory trim. Aftermarket wheels, different wheel widths, offset changes, lowering, altered springs, or body changes can all influence clearance. That becomes especially important on 20-inch setups and on the wider 275/40R20 fitment used by several higher-output models.

A Challenger that has been changed from stock should be checked for wheel diameter, wheel width, steering clearance, and fender or suspension clearance before new tires are chosen. Looking only at the original trim specification may not be enough once the hardware has changed. A quick inspection of the current setup often prevents rubbing issues and helps narrow the correct tire choices more confidently.

Before driving a 2017 Dodge Challenger on new tires, inspect the wheels for the correct diameter and general condition, verify that all four tires match the intended fitment, and confirm that inflation is set properly for the installation. It is also wise to look over the suspension and steering for worn parts that could affect tire wear or straight-line behavior once the new tires are on the car.

A short clearance check is just as important as the tire installation itself. Turn the steering from lock to lock, look for any sign of interference at the inner fender or suspension, and make sure the car sits evenly. After the first drive, recheck pressure and watch for vibration, pull, or unusual contact marks. Catching small problems early protects both the tires and the Challenger.

Tires on a 2017 Dodge Challenger should be inspected regularly, not only when replacement time arrives. A monthly pressure and condition check is a sensible routine, and any car that sits for long periods deserves extra attention before road use. Tread wear, cuts, sidewall cracking, bulges, punctures, and uneven wear patterns are all worth watching regardless of whether the car uses 18-inch, 19-inch, or 20-inch fitments.

Owners of lower-mileage specialty cars sometimes overlook tire age and condition because the tread still looks good. A Challenger that spends a lot of time parked can still develop issues from time, environment, or underinflation. Regular inspection also helps spot alignment or suspension problems early. Keeping an eye on condition between drives is one of the simplest ways to preserve ride quality and safe road manners.
